Oh God, this is so wrong. I shouldn't be watching this video. Three giggling teenage girls are flouncing around my bedroom, swapping swimsuit tops, comparing breast sizes and unknowingly putting on an erotic show as my hard cock strains against my shorts. I rationalize that my voyeurism isn't perverted because I'm not looking directly at Samantha, my granddaughter. I'm keeping my eyes focused on her two friends, Jenna and Angela. Anyone would look at these beautiful half-naked teens. It doesn't mean I'm perverted.

Jenna is not part of the breast size competition presumably because she would win it hands down. With thick, protruding nipples and wide areolas her tits are more adult-size than the teen-sized tits of her friends. Her gorgeous almond-shaped eyes, complements of her Asian mother, are as exotic as her mocha colored skin and voluptuous figure which I'm certain come from her African-American heritage on her father's side. She is laughing as her friends compare their much smaller breasts to see whose are larger.

Appointing Jenna the judge, they trade swimsuit tops to help her evaluate. Hell, I'd be the judge if my eyes weren't locked on Jenna's bouncing breasts while she dances around the room swinging her bikini top over her head and playfully making fun of her friends.

"You call those breasts?" she laughs. "These are breasts!" she boasts as she cups her brown tits and shakes them at her friends.

"Yeah, you're lucky you can stand up straight," Samantha quips as she pulls her top loose and hands it to Angela. A quick glimpse of my granddaughter's lightly freckled breasts sends unexpected pleasure signals to my already hardened cock. Her quarter-sized areolas are tipped with short, pointy nipples and her deep brown tan lines beautifully accent her perfectly shaped white domes. She's not going to win any size contests but she has impeccable breasts with erotic tan lines.

I tear my eyes away to check out Angela's tits before she tucks them into Sam's bikini top. Angela is a light-skinned Latina beauty with long black hair and it looks to me like she'll win the size competition against Samantha. Because of her olive complexion, her tan lines aren't as pronounced and it might be that her tits just look larger because of the way her wide areolas blend into her big puffy rose-colored nipples.

The girls are having trouble determining who's tits are larger and I watch them swap tops a couple of times before Jenna finally uses her phone to take pictures and compare them side by side. The whole time, Jenna is bouncing around the room topless, diverting my attention away from the other two girls.

My cock is throbbing but I don't want to get caught jacking off to explicit video of my granddaughter and her friends. I check my watch but I'm not even sure how long the girls have been gone. Seems like about an hour. Maybe I could risk a quick yank. Standing up, I glance out the window as I start unbuttoning my shorts. Damn! The subjects of my erotic video are already walking up from the beach. This will have to wait until later.

You may not believe it but this all started rather innocently. Samantha asked if she and her friends could stay with us during beach week. My wife and I retired to our beach house a couple of years ago and have been the destination vacation for our kids and grandkids ever since. We love having family around and I certainly didn't mind that Samantha and her friends wanted to spend the week after graduation parading around our house in skimpy bikinis. Although all three girls are eighteen, we checked in with their parents and assured them we would be responsible chaperones. It was true at the time we said it.

A couple of days after they arrived, my wife received a call from her brother-in-law saying her sister was very sick and had been admitted to the hospital. She caught the next plane to Oregon, leaving me with three beautiful teenagers in the house. I admit that I love seeing their nubile bodies displayed in an ever-changing array of swimwear but I swear that spying or making videos was the farthest thing from my mind.

After breakfast, the morning after her grandma left, Sam asked if they could use our bedroom to change for the beach. This was not an unusual request. Our room was the largest bedroom and would be less cramped with three people in it.

"Sure, just let me grab my MacBook," I said, heading into the bedroom as the girls cleared the table. The spacious room was set up with a bed, dresser and nightstands on one side and a desk, filing cabinet and desk chair on the other. I grabbed my computer and came back into the kitchen to find the girls laughing and blushing as they finished washing the breakfast plates and glasses.

"I'll be the judge!" Jenna laughed as they grabbed their swimsuits from the other bedrooms and raced each other into my bedroom.

I smiled at their youthful energy as I flipped the MacBook open. It was already on and I noticed the webcam app flashing in the upper corner. Clicking on it as I took a sip of my coffee, I almost choked when the screen filled with images of my granddaughter and her friends laughing as they stripped off their clothes. Fuck! I'd forgotten about the webcam.

I bought an external webcam last year when my wife and I got tired of trying to crowd in front of the laptop while Face-timing with our grandkids. We must have left the webcam on after talking with our daughter yesterday morning about my wife's travel plans.

I knew what I was doing was immoral and maybe even illegal but I rationalized that it was an accident. I hadn't planned to do this. I knew the right thing to do. With one click I could cut the webcam's Bluetooth connection and no one would be the wiser. Spying on my granddaughter and her friends was absolutely wrong on so many levels but I figured one quick peek wouldn't hurt and then I'll click to disconnect. As I watched them pull their sleep tops over their heads; their young, hard bodies and their innocent beauty were mesmerizing.

I adjusted my shorts around my stiffening cock as these three panty-clad teenagers compared their naked breasts in the mirror over my dresser. My eyes darted from one girl to the next, trying to take in everything at once. I've always loved looking at photos and videos of teenage tits but these girls were right in the next room. It was such a fucking turn on that my quick peek lasted much longer than I intended.

Sam was the first one to strip off her panties and it seemed so perverted to wish that my own granddaughter would turn towards me so I could see her pussy. She has a beautiful apple-cheeked ass, lightly frosted with her ever-present freckles that are more prevalent between the tan lines.

Jenna and Angela followed suit, revealing firm young asses that were every bit as enticing as Samantha's. I stared wide-eyed at Jenna's large breasts, hanging deliciously from her chest as she bent over to remove her panties. Her nipples jutted out nearly a half of an inch and I doubt they were even aroused. I was so absorbed in Jenna's mammary display that I almost missed seeing Sam's pussy as she turned momentarily towards the camera and then back to the mirror.

Fuck! I only saw it for a few seconds but my cock responded instantly. Her tan lines frame a small patch of neatly trimmed blonde pubic hair. The triangular shape makes it look like a little arrow pointing down towards her hidden treasure.

I knew I was taking more than the peek and I should have clicked to disconnect the webcam by now. I was honestly just going to do it but then Angela turned and started walking towards my desk, directly into the camera. The webcam is on a shelf over the desk and takes in most of the room. I studied this naked teenager, taking in all of her attributes at once, from her perfectly round, puffy nipples to her thick black pubic hair. She was laughing at something Sam said as she reached out towards my desk.

"I can see why your grandma married your granddad," she said, holding up a copy of our wedding photo that I keep on my desk. "He was a damn good looking guy."

"Still is if you ask me," Jenna came up behind Angela and looked over her friend's shoulder at the picture. Angela handed it to her as she turned away. My cock sprang to attention as I got my first look at Jenna's fur-lined pussy. She was standing perfectly still, almost filling my screen with her large tits and exotic looking pussy. I was devouring her body with my eyes. Her thick nipples were pointing right at me but I could barely look away from her spongy black pubic hair. I was rubbing my hard cock through my shorts.

These girls were putting on the most erotic show I had ever seen and they were hardly doing anything. I knew if I didn't click soon I'd regret it later. My hand was shaking as I finally grabbed the mouse and clicked ... on the record button.

When they finally emerged from my bedroom, I was sitting at the kitchen table innocently checking my email. I was watching the entire video again when I spotted the girls coming up from the beach.

"You guys weren't gone long," I say, looking up from my computer screen. I try to keep from staring but as I look at these three girls in their sexy bikinis all I see are their naked bodies prancing around in my room.

"It's too hot," Sam says as she grabs a bottle of water from the fridge.

"And there weren't any cute guys," Jenna adds with a mischievous smile.

"And the old guys that were there acted like they'd never seen a girl before," Angela chimes in. "I swear there was actual drool running down their chins." She laughs as she takes a sip of Sam's water.

"Well, I can't blame them," I wink. "You three would turn heads wherever you went."

"Which head?" Jenna asks with a more lascivious smile. My cock twinges at the mention of an alternative head but Sam answers before I can think a worthy comeback.

"Jenna!" Sam yells, her face turning a bright shade of red. "Don't say things like that in front of my grandpa."

"He doesn't mind, do you Granddad?" Jenna asks. "Anyway, I'm just playing."

"I don't mind," I answer. "It's all in fun, Sam." This time my wink is specifically directed at Jenna and she rewards me with a kiss on the forehead. As she pulls back from the kiss, her barely covered tits hang enticingly just inches from my face. I swallow hard as I stare at her generous cleavage and she takes her time standing back up. Hmm. It appears she is enjoying my reaction. I don't know Jenna well, this trip is the first time we've met her and I'm not sure what to make of this.

"We're just going to hang by the pool, okay?" Sam asks, interrupting Jenna's show.

As they head out the door it appears that Jenna has added a little more swing to her step. Her bikini-covered ass is swaying hypnotically or maybe I'm just imagining it. Maybe I'm a little over stimulated from viewing the video and I'm reading more into this than is actually there.

I check my email and then settle into my easy chair with a recent mystery novel. I find myself reading the same page over and over as my eyes wander out past the sliding glass door to where the girls are lounging on the covered patio. They've moved the lounge chairs into a circle and seem to be having a rather intense discussion. Sam gets pretty animated but the discussion seems to be focused on Angela. They go quiet for a few minutes and then Jenna points at me and the discussion picks up again. I thought I'd been caught staring at them and then I realize she was making reference to me but can't actually see me through the reflective glass.

"Um ... can I talk to you for a minute?" Sam asks, opening the patio door and stepping inside.

"Sure, honey. Is something wrong?"

"Kind of, but not really," Sam answers cryptically. She sits on the ottoman a few feet to the side of my chair and pushes her hair back over her shoulder. I reflexively glance at her breasts, picturing them naked before I can catch myself.

"Whatever it is, I'm all ears." I smile, making eye contact to encourage her.

"It's confidential," she says very seriously.

"I can keep a secret."

"Even from our parents?" she asks.

"Unless it is something that puts you or your friends in danger, yes." Samantha laughs.

"No danger but Angie has a problem and we think you can help us figure it out," she says quietly.

"I'll do whatever I can," I tell her honestly, unable to imagine what kind of problem Angela might have that I could help.

"It's about sex," she says, matter-of-factly.

"Okay..." I wait for her to continue but Sam just looks at me and then glances towards her friends on the patio.

"Confidential, right?" she asks again.

"Cross my heart, Sam. What is it?"

"Well..." Long pause. "First of all, we're all sexually active, okay?" She seems to be testing the waters to see if I'm going to freak out at this revelation.

"I'm not completely shocked," I answer. "You're all over eighteen and extremely desirable young women."

"Thank you." Sam's almost blushing and she takes a deep breath before she continues. "Angela has a steady boyfriend and they ... have sex regularly." She pauses again and I just wait for her to continue. I think I know where this is going and I'm not sure I'm going to be able to keep my confidentiality promise.

"A lot of our friends who are having sex, including Jenna, go on and on about their orgasms and how their boyfriends leave them breathless. Angela thinks something might be wrong with her because sex isn't doing that for her." She stops again and just looks at me.

I just nod, not trusting myself to speak. I wasn't expecting that. An hour ago I was getting ready to jack off to video of these teen beauties getting naked and now they want to discuss their sex lives with me. Fuck!

"We've told her that nothing is wrong with her but Jenna thinks that if you talk to her it might help. You know, because you're older and more experienced."

I don't know what to say. Of course, I'd love to hear about Angela's sex life, but I'm no therapist or doctor. What can I tell her?

"Will you please talk to her, Grandpa?" Sam asks.

"Sure, Sam. When do you want to do it?" I ask wondering why my wife isn't here to help with this.

"Right away before she changes her mind, okay?" Sam is already getting up and moving towards the door as my mind races to catch up with this weird turn of events.

Okay, what's the worse that can happen? I get to hear all about Angela's and maybe Jenna's sex life. Who knows, this could be better than reading erotic stories on line. I follow Sam as far as the kitchen and grab a diet coke from the fridge before sitting down at the kitchen table.

"So ... you think there might be something wrong with you, Angela?" I ask as all three girls settle in around the table.

"Yes sir," Angela answers quietly. "And um ... you can call me Angie, okay?"

"Okay, Angie. Why do you think the problem is with you?" I ask, trying to act like the responsible adult.

"Because unless these other girls are lying, I'm not like them," she says, hanging her head.

"I'm not lying!" Jenna chimes in with a defiant look and maybe a little bit of a smirk as she looks right at me.

"Just because other girls are experiencing more intense orgasms doesn't mean there is anything wrong with you, Angie."

"That's what I told her," Sam adds.

"Maybe she won't take your word for it because you've only been with a guy that one time and don't have a steady boyfriend," Jenna almost whispers to Sam before turning to me. "Tell her Granddad that it is as much what the guy does than what the girl does." I'm not sure exactly what that means but I try again with Angie.

"Why don't you just tell me what you and your boyfriend do when you're together and maybe we can figure this out." I tell her, unexpectedly anxious to hear all the juicy details.

"We fu ... have sex. That's what we do when we're together."

"You can say fuck if it's more comfortable. I'm not offended," I answer. "I realize you guys fuck but what else do you do?" Angie is looking everywhere except at me, and I realize that maybe all of us sitting here isn't such a good idea.

"Would you rather we talk about this in private?" I ask. "We can go into my office." It's actually my bedroom but that might have sounded weird.

"NO!" Her head jerks up. "They can stay. I'm just not sure why you need to know exactly what we do or who's on top?" she says.

"Well ... I think I agree with Jenna that if you're not having an orgasm it might be because your boyfriend isn't taking enough time."

"My boyfriend is fine. It's me that can't have the orgasm." Angie is almost in tears and I wonder what I've gotten myself into.

"Angie, all I'm saying is that guys usually get off faster than girls. That's a fact. If the girl isn't getting off with the sex it can usually be fixed by increasing the foreplay. I don't know if that's the problem unless you tell me what you're doing."

"I told you he would know all about this stuff," Jenna says, smiling that same lascivious smile that she gave me when I was checking out her tits.

"Look, maybe this is a conversation that you should have with your mother..."

"No way," Angie says, vigorously shaking her head. "She thinks I'll be a virgin until I get married."

"Well, your doctor then. Have a check up and tell him what you've told me." She's shaking her head before I even get the sentence out.

"He's friends with my parents. I wouldn't trust him to keep it confidential," she says.

"Well..." I don't quite know where to go with this. It seems obvious to me that her boyfriend either doesn't care enough about her needs or isn't experienced enough to know he's not satisfying her.

"What do you want to know?" Angie says, sitting ups straighter and giving me a full view of her sexy teen breasts. All three girls are still in their skimpy bikinis, which adds some nice visual effects to this erotic conversation.

"How about if I just list off some typical foreplay and you tell me if you guys engage in it?" I ask, trying to make her comfortable with the conversation.


"Kissing is probably a yes," I say, trying to ease into this.

"Yes," she laughs and I watch Jenna role her eyes. I give her a look and she stops.

"Sucking your nipples?" My eyes drift to her chest and I picture her teen sized tits nearly filling my computer screen.

"Uh huh," she nods.

"Blow jobs?" I ask, shifting in my chair and trying not to be obvious that my cock is enjoying this conversation. Jenna is smiling broadly but Angie is looking down and blushing as she nods her head.

"Does he return the favor?" I ask.

"What?" Angie's head jerks up and she looks confused by the question.

"Does he eat your pussy?" Jenna blurts out before I can clarify what I meant. "Just tell the man if he goes down on you." Angie is really blushing now.

"Um ... yes. He does." She says just above a whisper.

"When you blow him does he come in your mouth?" I ask.

"Does that matter, Grandpa?" Sam asks, sticking up for her friend's embarrassment.

"It goes with my follow up question, Sam." I answer. "Just nod if it's yes, Angie." She nods and I move ahead with where I was going.

"Do you cum when he eats you?" I ask. She shakes her head, no. The look in her eyes tells me she gets the point of the question before the others.

"But it feels good, you know, when he's licking me," she offers in her boyfriend's defense.

"I'm sure it does but if you suck him until he gets off, shouldn't he eat you until you get off?" All three girls are sitting up paying attention now and I'm wondering if any of them have been eaten to orgasm.

"I never thought of it that way," she says.

"So ... he eats you and then, I'm guessing moves right over you and you guys fuck. Is that right?"

"Usually. Sometimes I suck him again after he eats me. Because, you know, like he won't be hard enough right away for it to go in me easily," she seems to be getting more comfortable talking about it.

"I know this is a hard question and it's pure speculation but when he comes inside you ... what's his name?"


"When Rob comes inside you, about how close to orgasm do you think you usually are?"

"I don't know. I get really excited and it feels so good but when he collapses on top of me, I still want to keep going."

"Fair enough," I answer and then sit back in my chair considering what to say next.

"What? What are you thinking?" Sam asks.

"I don't think there is anything wrong with you," I answer. From what I've seen, everything is very right about her but I don't say that. "I think your boyfriend isn't experienced enough yet to get you off." I hold up my hand to stop her interruption. "There are a few things you can do about that."

"What things?"

"You can talk to him. He probably doesn't know. Tell him what you need and ask him if he'll try a few things to help you get off like he does." She's shaking her head before I even finish.

"You don't know him," she says. "He would feel like I'm putting him down and telling him he's not a good lover."

"He's not," I say before thinking about it.

"Trust me, that would not go over well," she says. "You said a few things. What else?"

"I have a feeling you're not going to like this one any better but you could go out with a guy who knows what he's doing and verify for yourself that it's not you."

"I can't go out on Rob! He's my boyfriend." Her head is swirling between Jenna and Sam like she's pleading with them to agree with her.

"Maybe Jenna would loan you her boyfriend just for a night so you can experience what she's getting." I don't really think this is a good idea but I said it just to get a rise out of Jenna.

"I got a better idea." Jenna says, looking right at me with that half smile of hers turning up her cheek bones and making her almond shaped eyes twinkle exotically. "Why don't you show her, Granddad? You're experienced and seem to know a lot about female orgasms."

I don't have a comeback for that. I'm sure my mouth is hanging open. I just stare at Jenna's defiant smile as she sits back and folds her arms across her ample chest. Touché. I smile at her like she just made the biggest joke ever but Sam's not laughing.

"That is a great idea!" Sam says excitedly as she sits forward and tries to gauge my reaction.

"It's a very bad idea," I say, not taking my eyes off Jenna.

"Why?" Sam asks.

"Because..." I pause momentarily, as my mind sorts through the myriad of reasons why I won't be giving Angie any orgasms. "I'm too old, too married and she should be fucking someone her own age."

"You just made a pretty strong case that guys her own age aren't able to give her what she needs," Jenna retorts. "You are obviously not too old to fuck," she continues while glancing at my crotch. I fight the urge to look down and see if my hard cock is really that obvious. "Besides it's not like you're going to marry her or anything. You'll be like a teacher or mentor or whatever."

"It's the whatever that bothers me," I respond.

"Do I have a say in this?" Angie asks quietly.

"There is nothing to have a say in because I'm not doing it!" I say, pushing my chair back and standing up. I'm about to make a dramatic exit when I notice all three girls staring at my crotch. This time I do look down and sure enough, the front of my shorts are tented straight out in front of me.

"Fine, I'm human. So sue me!" I say and make as dramatic an exit as I can, stomping off to my bedroom.

Flopping down on my bed, I feel really stupid for the way I handled that. But what the fuck was I supposed to do? Why would Jenna even suggest something like that. What would happen if Angie's parents ever found out? Or my wife? What the fuck is she thinking? And Sam thinking it's a great idea. What's that about? I'm staring at the ceiling when there's a knock on the door jam of the open door.

"Hey," Angie says. "Can I come in?"

"Sure." I sit up on the edge of the bed. "I'm sorry about all that. I'm sure they mean well," I say as Angie comes over and sits next to me.

"I understand why you got weirded out," Angie says with a nervous laugh. "But ... um ... would you at least think about it?" she asks. She's sitting right next to me and she turns sideways on the bed so she's facing me. "I'd really like to know for sure if something is wrong with me." He eyes are welling up with tears and I instinctively put my arm around her.

"There is nothing wrong with you, sweetheart." I tell her as I pull her against me. She's still in her bikini and I wasn't anticipating the warmth of her bare skin. My heart thumps in my chest as I will my cock not to react.

"You don't know that for sure," she says, leaning her head against my shoulder. Damn! Why am I arguing with her? Because she's an eighteen-year-old girl who just needs a better boyfriend!

"I'm pretty sure," I say. "And like Jenna said, I have some experience with this." I try for a lighter tone but instead I've spurred her on.

"That's why you would be so perfect," she says. "It wouldn't be like I'd be going out on my boyfriend ... well at least, not with anyone at school who would tell everyone about it. And I'd really like to know for sure. Please! Just tell me you'll think about it."

With a heavy sigh, I relent. "I will think about it ... but that's all ... no promises, okay?"

"Okay!" Angie hugs me tightly and kisses me lightly on the cheek. "Thank you," she says and gets up to leave.

"Angie," I call her name as she gets to the door. Her bikini bottom has ridden up between her cheeks and I'm treated to a wonderful view of her near naked ass.

"You need to think about this, too," I tell her as she stops and turns towards me. She just smiles. "I'm serious, this shouldn't be a spur of the moment decision."

"I'll think about it, Granddad," she smiles. "It's probably all I'll think about." She disappears into the hallway.

Fuck! Most guys would kill to be in my position — a beautiful young teen wants me to prove she can have orgasms. It's like the ultimate fantasy. So why am I feeling so desperate? Not desperate, I'm scared shitless. It's one thing to fantasize about these young girls and jack off to a video of their naked bodies. It's something else to actually have sex with one of them.

When I finally emerge from my bedroom, the girls are out on the patio. Music is playing on one of their phones as Sam paints her toenails and Jenna braids Angie's hair. Such typical teenage behavior makes me smile and I decide we should just have a fun afternoon.

"What do you guys want to do this afternoon?" I ask, walking onto the patio with a cold beer. They turn almost in unison, with big wide grins. "Besides that," I add and we all laugh.

"How about miniature golf?" Sam asks, looking from me to her companions for support.

"I like that," Jenna says, "since what we really want to do is off the table." She smiles that wonderfully lascivious smile again before turning her attention back to Angie's hair. My cock stirs and I wonder if I'd be as resistant if it were Jenna instead of Angie who wants me to fuck her. Probably, they're the same age but Jenna just seems more, I don't know, womanly than the other two, in both looks and actions.

"How about lunch at the pier and then miniature golf?" I ask, getting nods all around. Angie is the only one who hasn't actually spoken her ascent.

We have a wonderful afternoon. The girls are really fun to be with and there is relatively no sexual tension between us. It helps that their shorts outfits are much less revealing than the bikinis I was used to seeing them wear. It is also clear from their playful teasing and the way they finish each other's sentences that they are very close friends and have been for a long time.

When we get home, I grill burgers and we eat outside. After dinner, the girls leave to sit on the beach until sunset and I call my wife. She says her sister is doing better but she won't be home for another week. I assure her that we were doing fine and that she doesn't need to worry about us. Or does she? I retreat to my bedroom to think.

The question is still looming out there and I haven't decided what to do about it. After having adamantly declined, I don't realize until just this moment that I'm actually considering it. She is a beautiful young girl with a problem I am certain I can solve. There is no question that her inexperienced boyfriend is the problem.

I lie down on my bed and try clearing my brain of the image of her sexy young body so I can treat the decision objectively. Every time I mentally list the pros and cons the cons outweigh the pros by a huge proportion. The trouble is that my dick stays hard through the whole process, tipping the scales in favor of the pros. Fuck!

I hear the girls come back in and the TV burst to life in the living room. I consider initiating another discussion to persuade them how illogical this is but decide avoidance is a better strategy. I stay in my room, trying to read my book. As you can imagine, my mind keeps wandering.

I'm just putting my book on the nightstand and turning off my light when the TV shuts off and I hear the girls make their way down the hall to their bedrooms. A light knock on my door and Sam sticks her head it.

"Goodnight, Grandpa," she whispers into the dark room

"No goodnight kiss?" I ask.

"I wasn't sure you were awake," she says as she makes her way to my bed and crawls up beside me.

"Just turned the light off," I answer, kissing the top of her head as she snuggles against me.

"I'm sorry about this morning," she says. "I didn't mean to put you in such an awkward position."

"No, I'm sorry," I respond. "I shouldn't have freaked out on you guys. My reaction was inappropriate. I should have stayed and talked it through some more."

"Only part of your reaction was inappropriate," she laughs, tickling my ribs. I'm glad she can't see me blushing in the dark thinking about my tented shorts.

"I'm sorry. I couldn't help that," I say, squirming away from her hand.

"At least we know you weren't repulsed by the idea," she laughs again before settling her head back down on my shoulder."

"Yeah, that was pretty obvious but you know this is wrong, don't you?" The length of her silence gives me my answer and I realize that the right and wrong argument isn't going to get any traction.

"It's just that Angie is so self conscious, you know?" Sam lets out a long sigh and leans up to look in my face. "She thinks because her boyfriend is inept that there is something wrong with her. Now you won't have sex with her so she thinks there's something wrong with her. Instead of helping her, we're just making it worse!" She blurts this all out in one breath and then plops back down. "I just want to help her," she whispers.

While I'm glad to hear that my granddaughter realizes that there is nothing wrong with Angie, I'm not sure how me fucking her is going to build her self-esteem. I choose my next words very carefully.

"Are there other examples of Angie having low self-esteem?" I ask. Sam thinks for a long time before answering.

"No. I think it's just with sex," she finally answers. "She's very confident in sports and she's really smart and does well in all of her classes." Sam takes a breath before continuing. "I know she doesn't like her body. She's always complaining that her breasts are too small and she's always afraid of losing her boyfriend to someone with a better body. That's why she won't talk to him about sex. She's afraid of losing him."

It occurs to me that this is probably typical teenage girl dramatics and I wonder if Sam feels the same way.

"You two have similar bodies, you don't feel that way do you?"

"No, my breasts are a little larger," she says, confirming who won the competition. "But even if they weren't I don't think my body defines who I am and I've tried to tell Angie that but..." her voice trails off and we're silent for a while.

"Will you at least consider helping her, Grandpa? I know you don't think it's right but is it right for her to feel rejected? And besides you could show her what a lousy fuck her boyfriend is, right?" She kisses me on the cheek and rolls over to get off the bed.

"You've given me a lot to think about Sam," I answer noncommittally.

"Don't take too long," she says. "We've only got tomorrow. Remember grandma said that Jenna and Angie's boyfriends can come down on Friday to join us for the weekend." I had forgotten that arrangement until just now.

"I'll have an answer in the morning, Sam." I assure her, wondering how I'm going to decide. "But don't get your hopes up."

"Like my teachers always tell me, don't over think it," Sam says with a big smile before leaving me alone with my thoughts.

I toss and turn all night as I consider the risks, not the least of which is my wife finding out. We've continued to have a very active sex life. We're not as flexible as we once were but we don't confine ourselves to the missionary position either. We have both always been addicted to oral sex. I'm not worried about whether I'll be able to give Angie several mind-blowing orgasms but I am worried about what these teenage girls might say or tweet when this is over.

The girls usually sleep late but since I'm awake early, I run a few critical errands and I'm sitting at the table when they wander into the kitchen.

"I'll do it," I say without any preamble.

"Really?" Angie's face lights up and all three girls rush over to hug me.

"But we have to talk about a few things first." I motion them to the chairs and they take their seats, looking at me like they are about to hear the meaning of life.

"First, you asked me for confidentiality, Sam." She nods. "I have to ask you guys the same thing. No discussing, tweeting or anything else. When it's over, no one talks about it, agreed?" All three girls nod their ascent.

"Second..." I don't really have a second point. "Well, I guess that was the main thing but I want to talk about how we're going to do this," I say, looking at Angie. "How did you envision it? Will you and I just go into my bedroom while Sam and Jenna wait out here?"

"No way," Jenna answers for her. "We're all coming into the bedroom. We want to see what this is all about."

"That's alright isn't it?" Sam looks questioningly at me.

"I think that's up to Angie," I answer, not sure how I feel about an audience.

"I just assumed they'd be there," Angie says. "That makes it less like I'm cheating on my boyfriend and more like you're teaching us stuff." Her logic isn't infallible but if they all want to be there while I fuck their friend ... damn! What have I gotten myself into?

"Okay. I've been thinking about this and we're not going to just plop down on the bed and start having sex. We're going to spend the day together and work towards it gradually, like you would in a real relationship, okay?"

"Whatever you say," Angie answers, obviously eager to get past the talking stage.

"You're the boss," Jenna adds. Sam just smiles appreciatively at me.

"Breakfast first and then we'll go in the pool," I announce. "I'll fix breakfast while you guys get your suits on."

The girls rush to the bedroom while I whip up some eggs and bacon. After the dishes are cleaned up we head out back to the pool. I don't have this all planned out but I know I want to start with a relatively normal setting and then gradually make it more erotic.

I grab a beach ball and we start tossing it around in the pool. I stay focused on Angie even though Jenna's bouncing breasts are terribly distracting. We're all having fun and after a good round of innocent splashing I gradually begin touching Angie in a more familiar manner. At first I'm just playfully grabbing her around the waist, pulling her against me and then patting her fanny as I push away. I progress to kissing her neck and telling her how beautiful she is while my hands wander over her exposed skin.

Sam and Jenna instinctively retreat to the other side of the pool with the beach ball and I turn Angie towards me. Brushing her hair from her eyes, I kiss her tenderly on the lips. My hands are lightly caressing her shoulders as her lips part and my tongue slides inside her warm mouth. She is a surprisingly good kisser and my hands roam her naked back as our tongues dance in and out of each other's mouth. Sam and Jenna have climbed out of the pool and are sunning themselves on the deck as they watch our increasingly intimate encounter.

Cupping Angie's firm young ass cheeks, I pull her against me and my cock makes no secret of its arousal level. Damn if she doesn't surprise me again by wrapping her legs around me and grinding her bikini-covered pussy against the bulge in my suit. With our tongues continuing their tasty probe, I untie the strings holding her bikini top and slip it out from between us.

Angie halts the kiss, realizing she is topless in my backyard. Good, I was finally able to surprise her. It's fairly secluded back here and there isn't much chance anyone will see us but I have found that just the idea of being exposed outside tends to enhance the arousal.

"I'm going to lick the water drops from your naked breasts," I whisper, wanting to stimulate her thoughts as well as her body. Her only response is an audible sigh as she gives into her urgings and crushes her firm tits against my chest. "I can't wait to get my mouth around your incredible nipples," I add.

Unhooking her legs from behind me, I stand Angie back on her feet in the water. With my hands firmly on her waist, I smile at the sight of her lovely teenage chest. It's even more enticing in person than on the video but my gawking is making her self-conscious and she moves her hands up toward her chest.

"Don't cover yourself," I plead, pulling her hands back down.

"They're kind of small," she says quietly as her face blushes and she lets her arms drop to her sides.

"They're perfect," I counter. "Like a masterful work of art." Leaning forward, I start licking the beads of water from the valley between her mounds. This is unbelievable. My cock is rock hard as I lick up and down, gradually widening my path to include the inside curves of her tits. Angie rests her hands on my shoulders as I slowly swirl my tongue all around the contours of her pert young breasts, consciously avoiding her puffy nipples.
