I’m sure it was the two glasses of wine we’d just had that loosened Julie, my sister-in-law up enough to embark on the conversation neither of us will ever forget. It was Friday afternoon and Steve was due home anytime. His sister had just left her husband and was staying with us while looking for an apartment.

“Please tell me my baby brother knows how to use that horse cock of his. I had a couple of big ones when I was in college—not as big as Steve’s of course, but neither of those guys could last long enough to do much for me. In fact, one of them couldn’t even keep it up long enough to change positions.”

I couldn’t believe it when I heard myself say, “Well, fortunately, your brother doesn’t have either of those problems. He does just fine in that department.”

“Oh really? Do tell.”

I felt my face grow flush. “Uh, that’s a bit more than I feel comfortable discussing with someone ... especially his sister.”

“Oh c’mon. It’s just between us girls. I won’t repeat anything to anyone. I promise. My lips are sealed.” And she made a zipping motion over her lips.

I thought about it for a minute before deciding that sharing a little couldn’t hurt anything. “Well, if you really want to know, a friend of his gave him some Viagra to try last year, and he’s been using it ever since. I told him he didn’t need it—that he satisfied me just fine without it, but I must confess, once we tried it, we were hooked. He’s been an animal in the sack ever since. That stuff is amazing.”

“Viagra!” she almost shouted, her hand flying to her chest. “He’s 29. Surely he doesn’t need--”

“He doesn’t need it.” I defended my husband. “But holy shit! After taking it, he lasts even longer, and just needs a few minutes to be ready again. He can literally go all night, and his ... penis gets so hard I sometimes worry that it will burst.”

“Oh my gawd! I saw it hard once when I walked in on him while he was jacking off. That was back when he was still a teenager. He covered it up quickly, but I got a great look at it. I can only imagine what he’d be like after taking Viagra. I’d probably cum just from looking at it.”

Thankfully our conversation was interrupted when her phone rang, but it didn’t last long. Then right out of the blue, Julie asked me “Okay, so my baby brother can keep that monster cock of his up long enough to take care of business, but how is he in other areas?”

“What ... what other areas?” I asked, blushing again.

“You know. Is he a good lover, or does he just climb on, fuck, and then roll over and go to sleep? Is he any good at foreplay? Does he know how to use his tongue? Shit, girl! How is he at eating pussy?”

I was shocked at both her language and her questions. “I ... well ... I’m not sure how to--”

“Deb, he’s good at it or he’s not. Which is it?”

“I ... I don’t know.”

“You don’t know? How can you not know?”

I was almost a virgin when we got married. My one previous experience with sex consisted of 10 minutes in the backseat of Randy Boyle’s car, and that wasn’t even worth remembering. “We don’t ... you know ... do that other stuff.”

Julie’s jaw dropped. She stared at me for almost a full minute before somberly mumbling, “You don’t do ‘that other stuff’. Are you telling me you two never have oral sex? He doesn’t go down on you, or you on him?”

“Uh, yeah ... we don’t do that.”

“But you have with other guys, right? You have done it before, haven’t you?”

I couldn’t answer so I just shook my head.

I didn’t think it was possible, but my sister-in-law’s eyes grew even wider. “You’ve never experienced oral sex—never given a blowjob? You’ve never had your pussy eaten?”

Again, I just shook my head. Until that moment, the thought of doing those things had never crossed my mind. Steve never brought it up, and I was happy with our sex life, so I hadn’t seen any need to experiment with other things.

“Oh my gawd!” Julie’s tone reflected her amazement. “Girl, you have no idea what you’re missing.”

Fortunately, Steve came through the front door and the conversation ended right there.

Steve and I had been married for just over three years, but I’d never seen him have more than one drink on any given day. That changed after supper. I couldn’t really blame him, since his sister had been hitting the wine enough to introduce sex into the conversation again. That was a topic even he and I didn’t talk much about.

Julie’s promise to keep our earlier conversation just between us went right out the window when she blurted out “So, brother of mine, I understand that you and my sister-in-law have a ... let’s say ‘limited’ assortment of activities in the bedroom.”

I’m sure my face had never been flusher than it was right then. I glared hard at her but she barely glanced my way. Steve, on the other hand, jerked his eyes toward mine, then immediately got up to mix his second Jack and Coke.

He didn’t look around while asking “So, exactly how much wine did you two have before supper?”

Julie laughed and then answered, “Just enough to loosen your wife up enough to participate in a little girl talk.”

“So it would seem.” He said with a frown on his way back to the couch. “And apparently enough that you now want to draw me into your girl talk.”

“Don’t worry, little brother, Deb did nothing but brag about your sexual prowess, even before you got hooked on Viagra.”

Again, my husband jerked his eyes toward me with a red-faced glare.

I couldn’t remain quiet any longer, “Julie, let’s change the subject, please.”

Steve seconded that, “That’s a great idea.”

“You two are acting like old prudes. It’s no wonder you don’t have any variety in your bed if you can’t even talk about it. You do know there is more to sex than missionary intercourse, don’t you?”

My husband said, “We do just fine, thank you.”

From the tone of his voice, I could tell my husband was starting to get irritated, but Julie wouldn’t let up. She shook her head, “For now maybe, but it won’t last. You’ve only been married three years. How long do you think you’ll stay interested in fooling around, especially without any variety to keep things exciting? Would it kill either of you to try some new things?”

Steve got up and went to the wet bar for third time. “Ok, sis, what kind of things do you think we need to try to keep things ‘exciting’?”

I knew the alcohol was starting to affect his judgment, otherwise he never would have swung the door open for her like that.

“Hell, you could just start with the very basics like oral sex. Then, if you like it—or even if you don’t, move on to trying other things. Don’t practice contempt prior to investigation. Try everything.”

Steve let out a tipsy chuckle, “I’m not sure I’d enjoy getting all that hair between my teeth, let alone in my mouth and throat. It just doesn’t sound all that appealing to me, and I’m sure Deb can live without gagging while trying to do that to me.”

Now I knew we were in trouble. Steve was actually starting to think about what his sister was saying, and he was defending us for not following her advice. Then he turned to me and asked, “Have you ever tried it?”

I just shook my head before getting up to head to the wet bar myself. I hadn’t had any wine since long before supper, so I mixed myself a Screwdriver. I made it much stiffer than my usual, figuring I was going to need it if I was going to have to listen to more of this.

“See! That’s my point. She doesn’t know if she likes giving head, because she’s never tried it. And I’m sure she’ll love you going down on her after you learn how. And besides, if getting hair in your mouth is the only thing holding you back, she can always shave.”

“The shaving thing sounds a little dangerous to me. I might cut off something.” I said with a chuckle.

“You’ll be fine ... the first time can be a little tough, but after that it’s a piece of cake. I’ll help you the first time.”

“Now that I’d like to see.”

I couldn’t believe my husband said that. “What, me clean shaven?”

“No, you getting shaved by my sister. That would be really hot!”

Julie sprang to her feet and looked at me, “Well, what are you waiting for? Go get a pan of hot water and a towel. I’ll go grab my razor and shaving cream. This is going to be fun.”

“I ... I...” was all I could get out as I looked at Steve only to find him grinning from ear to ear. “Really?” I finally managed.

I couldn’t believe my ears when he said “Hell yeah, go for it, but only if I can watch.”

“I can’t believe I let you two talk me into this.” I said as I pulled off my slacks and panties and sat on a towel in a kitchen chair. I looked at Steve and he was still grinning, so I handed him my empty glass and asked him to mix me another screwdriver, “and make it a strong one.” He was back in a flash, I assume because he didn’t want to miss any of what was happening. Julie was kneeling on a pillow between my legs and was just starting to trim my abundant bush with scissors. It was odd having another woman touch me there, and odder still doing this right in front of my grinning husband.

If I am being honest, I have to admit, by half way through it, I was as turned on I as I can remember ever being. The alcohol had apparently calmed my nerves enough to enjoy the sensations ... and the intimate attention. Several times, I was sure my sister-in-law touched my clit on purpose. That was something Steve rarely did during foreplay. He typically just finger-fucked me until I begged him to put his wonderful cock inside me.

When she was finished, the only hair remaining was a small strip above my slit, and that was trimmed closely so as not to cause a problem should my husband decide to go down on me. To me, that was still in question. I wasn’t sure he ever would.

After rinsing and drying me several times, she turned to her brother, “There you have it. All you need to do now is give it the tongue test?”

“The tongue test?”

“Of course, silly. You have to tongue test it to see if it’s smooth enough. Your tongue and lips are much more sensitive than fingers.” She stood up and motioned for him to take her place between my legs. “So, go ahead and test my handiwork. What are you waiting for, a written invitation?”

“Uh ... I think that can wait until we are alone.” He mumbled.

“Oh no it can’t.” Julie shot back. “I’ve got the water here, the shaving cream here, and the razor here. If I missed something, now is the time to let me know. Now get your lazy ass over here and test it ... or do I have to do that for you too?”

Steve’s eyes shot open, as I’m sure mine did. But the next words out of my husband’s mouth simply blew me into outer space.

He let out a disturbing chuckle. “You do it then. I dare you.”

“Steve!” I gasped.

Julie showed him a naughty grin, but then she moved quickly, “Okay, you asked for it.” And then before I could protest, she was on her knees on the pillow again. In the next instant, she had her mouth on my pussy. I was in too much shock to know how it felt. I just knew I was staring down at my sister-in-law as she licked up and down my pussy lips and sucked each one into her mouth. After only a few seconds, she began swirling her tongue around on my already swollen clit. Seconds later, I felt a powerful orgasm building rapidly within my loins. Before I could push her away, it hit me, and seconds later, my world went black.

When I regained some measure of consciousness, I saw my sister-in-law standing with her hand on my husband’s shoulder and I heard her say with pride in her voice, “And that, baby brother, is the proper way to eat a pussy.”

But hearing her words didn’t shock me nearly as much as Steve’s reply, “Holy shit! I’ve never seen her black out before. I need to learn how to do that!”

Julie let out a loud laugh, and when she could, she said, “I’ll be happy to teach you.”

“You’d do that?” He asked earnestly.

“Sure. Your wife has the sweetest pussy I’ve ever eaten, so it will be my pleasure.”

“How many have you eaten?” He asked her.

Julie chuckled again, “More than a few. I’d have to stop and count, but right now, I need a fresh glass of wine. Would you do the honors?”

When Steve was out of earshot, Julie turned to me and said, “You didn’t freak out. You relaxed and let it happen. Good for you. I’m very proud of you, and I wasn’t kidding about how you taste. Your pussy is as sweet as honey.”

I was somewhat under the influence of alcohol and still basking in the afterglow of the best orgasm I’d ever experienced. I smiled up at her, “If you can teach him to do that—just like that, I’ll be in your debt forever.”

She chuckled again, “I’m sure he’ll be saying the same thing when I teach you how to give him a proper blowjob.”

For my first attempt at giving my husband a blowjob later that evening, I didn’t fly solo. My sister-in-law was right there with me. She described exactly what I should do, and then she demonstrated it—on her own brother. Even without Viagra, Steve’s massive cock jerked and twitched right in front of our eyes.

“My gawd! What a beautiful site that is. You’re one lucky girl.”

“Uh, thanks, I think.” My hesitation was rooted in my not knowing how I was supposed to feel about another woman seeing my husband’s erect cock ... and commenting on it. I finally shrugged inwardly, knowing that she was his big sister and had confessed to seeing it before and being impressed by it. I experienced similar uncertainty about what happened next, but again, I was able to shrug it off, probably because the whole situation—hell, the whole afternoon’s events were just so damn exciting and deliciously naughty, it overwhelmed my doubts, uncertainties ... and jealousies. Of course, I’m sure the alcohol helped more than a little.

The first time I teased the loose skin on his shaft just under the head with my tongue, my husband moaned his approval. And when I held his ten inch cock straight up and began licking up and down one side of his thick shaft, Julie moved in and did the same to the other side. Our tongues touched more than once, and after a few times, it evolved into more than accidental touching. Julie purposefully swirled her tongue over mine. Her arm was around my back, and every now and then, she would reach down and fondle my breast. I soon began wishing she would knead my breast harder and pinch my nipples, but I didn’t say anything.

After almost thirty minutes of toying with Steve’s cock, Julie announced that it was time to get serious. She showed me how to move my head up and down on him with the same rhythm my hand was moving up and down his shaft. Of course, I could barely get any of him into my mouth—the head and perhaps two inches. Julie could engulf over half of him with ease. “Don’t worry.” She whispered, “It’ll get easier with practice.”

And then she warned me, “When he begins to feel cum rising to his cock, his whole body will stiffen, especially his leg muscles. When you feel that, at least for the first few times, stop the motion with your mouth and concentrate on stroking him. Just keep your lips over the head. And then, when he starts to cum, take as much in your mouth as you can and then pull away and swallow. That part takes some practice, but soon, you’ll be taking his full load and loving every drop of it. In the meantime, just remember to keep stroking him with your hand until he tells you to slow down or stop. Just because there isn’t any more cum shooting out doesn’t mean he’s finished. All men are different, so it’s up to him to tell you until you learn what your man needs. Oh, and afterward, you’re going to owe me something.”

I pulled the head of Steve’s cock out of my mouth and asked “What?”

She showed me a sly wink, “You just get serious now and finish him off. You’ll find out soon enough.”

I did as my sister-in-law instructed, and it wasn’t long before I felt my husband’s legs stiffen. I wasn’t afraid. I wanted this. His first shot of hot cum startled me, but I remained committed. It took only seconds for me to pull back, but I kept stroking him. Gob after gob of cum continued to spew forth with each upstroke of my hand. It covered my hand and wrist, and some even ran down onto his crotch and thigh. Julie even moved in and licked up some of her own brother’s cum as it gushed out of his cock.

I’m not sure what I expected cum to taste like, but I was so caught up in the moment that I’m not sure I even tasted it. I do remember thinking that it had an odd texture. It wasn’t displeasing to me.

When Steve finally told me to stop, his sister gathered a huge amount of his cum on her tongue, then she grabbed my hair and crushed her mouth onto mine, forcing my lips apart. Her tongue found mine, and she shared my husband’s—her brother’s cum with me.

Our tongues had touched several times while licking his cock, so that wasn’t shocking, but those times could have been easily dismissed as accidental. This could not be dismissed. She held me firmly to keep me from pulling back. The combination of feeling her tongue on mine like that, and the texture of Steve’s cum on both our tongues, and the fact that I knew he was watching us was all simply overwhelming.

Before she pulled away, my clit came alive and another orgasm washed over my body. It wasn’t like before. It wasn’t as powerful by any stretch, but it was nice and warm and wonderful.

When she broke our kiss, Julie asked me, “How long does it take the Viagra to go to work on him?”

Steve answered for me, “Usually about twenty minutes. Why?”

She slapped her brother on the thigh. “Go take some now and clean yourself up. Then we’ll have a twenty minute first lesson on eating pussy.” And she punctuated her statement with a naughty giggle.

While Steve was in the bathroom, Julie pointed to my cum covered hand, “You’re not going to waste that, are you?”

When I just stared at her, she took my hand and licked some of her brother’s cum from it. She showed me a naughty wink, then pushed my hand toward my mouth. I did as she expected and began licking my husband’s cum from my hand and wrist. The taste and texture was pleasing to me. “Ummm” I moaned, to which she responded, “See, I knew you’d love it. I know I do.” And with that, she moved closer and helped me clean up the remaining cum.

When we were finished, my sister-in-law stood and offered me her hand. When I was standing, she whispered, “I think we’re way past the need for this.” And she grabbed the hem of my shirt and pulled it over my head. I raised my arms to allow it without protest. Then she began removing her own clothes and was soon standing before me totally naked. “Does this bother you?”

“No, but I do need another drink.”

“After you, my dear.” She motioned me downstairs with a silly giggle.

I felt very naughty going downstairs naked like that, and especially with my sister-in-law right behind me, but by the time we got back upstairs, I was much more at ease. Steve had returned to the bedroom and slid under the sheets. He was propped up by two pillows, his hands interlocked behind his head. When he saw us appear in the doorway, his smile turned into a wide grin. Julie pulled me to a stop just inside the doorway and slid her arm around my waist. “Enjoying the view?” She asked her brother.

“I sure am.” He answered, still grinning from ear to ear.

“Then enjoy it for another few seconds, and then get your ass out of Deb’s spot.”

It was a bit awkward just standing there like that—like I was saying “Look at me. I’m beautiful and sexy.” Even though I believe I am both of those things, I’ve never been one to flaunt it. At twenty-six and shapely, men do look my way. My blonde hair falls well below my shoulders, and my 36D breasts are slightly larger than would be considered proportionate on my slender frame.

Julie was very, very sexy. She was thirty-one and very slim and fit. Her hair was dark brown and just a bit shorter than mine. I guessed her breasts to be C cups, and they were beautiful and perky. Her pubic area was totally shaven. I had no doubt that Steve was already rock hard under the sheet, Viagra or not. And why not? It’s not every guy who gets to see his older sister like this. I didn’t blame him for looking at her more than me, even though he was doing his best to hide that fact.

Finally, Julie said “Ok, buster. Get out of bed and let Deb have that spot. She took one of the pillows that Steve had been resting on and told me to raise my hips. She then placed the pillow under my buttocks, but far enough up to keep it from being below my pubic area. Then she forced my knees up and apart.

As I had predicted, my husband’s cock was standing up proudly and twitching for attention. Just the sight of him standing there got me wet. He’s six one with broad shoulders and a muscular chest. His arms and legs were toned and firm as well. He had short black hair, and the most loving blue eyes you can imagine.

When Steve was between my legs, Julie pulled my knee up and over her back so that she could get closer. She reached out and trailed a fingertip along the outer edges of my lips. “Start here. Very gently lick all around, but don’t touch her clit or try to slide your tongue between her lips. Just go slow and gentle at first.”

I watched as my husband obeyed her instructions to the letter. I let out a low moan to let both of them know I was enjoying what he was doing.

“Now, lightly run your tongue between her lips, but don’t touch her clit—not yet. That will come later. That’s it ... just like that. Now go between them a millimeter farther each time or two. Yes, just like that. You’re a great student, baby brother.”

“Yes he is.” I said in what I hoped was a sexy purr.

Then Julie continued her coaching, “Now, take one of her lips between yours and gently lick and suck on it and then the other. That’s it. Do you like that, Deb?”

“Gawd yes!” I practically yelled.

Julie giggled and my husband let out a chuckle. “Now run your tongue up and down between her lips a few times.”

After he’d done that, she instructed him again, “Now lick farther up. You can lick her clit now, but don’t linger on it too long. Every now and then, suck her lips into your mouth and gently nibble on them with your teeth.”

The first time he did that, an unintended moan escaped me. The sensations were just too much to keep inside.

“Um, she likes that. You’ll need to remember that for future reference. But right now, wiggle your tongue down into her pussy a few times so you can taste what you’re doing to her.”

When Steve complied, she asked, “See, sweet as honey, isn’t she?”

I heard Steve moan out a muffled “Uh huh”. It gratified me to know that my husband approved of the way my pussy tasted.

“Now, back up to her clit. You need to start applying more pressure with your tongue now. Do circles around her clit, then over it, and then back down inside her. Keep repeating that until she lets you know she’s getting close. Then I’ll tell you what to do.”

I could barely keep my butt on the pillow. I was already close to orgasm, it’s just that she kept him moving around so much; I couldn’t quite get there. I needed to let her know, so I half moaned, half shouted, “Gawd! I’m already close. I need to ... need to cum now.”

Quickly, Julie instructed him, “Move to her clit and suck it into your mouth, then flick your tongue over it as firmly and as fast as you can.”

Steve obeyed, but I just couldn’t get over the top. I needed something. If I knew what, I would have told them, but I didn’t have a clue. Finally, thankfully, Julie said, “You’re loosing her. We can’t let her fall off the mountain. Move over.”

My husband quickly backed away and his sister took his place. Her mouth was on me in a flash, and my clit was between her teeth. The more pressure she applied with her teeth, and the faster her tongue flicked it, the higher I rose. I felt my butt rise up and Julie’s hands around my thighs holding her in place. And then it started. I felt it building until I screamed out “Harder!” And I felt her teeth close tighter and even tighter until I felt a blissful mixture of pleasure and pain.

My orgasm burst out in all directions from my clit. I needed it to last and I was afraid Julie would back off or ease up, so I grabbed her hair and pulled her mouth hard to me. The only words I could get out were “Gawd!” and “Harder!”

A second explosion rocked me, and then a third. Seconds later, the forth and even larger one hit me and I lost consciousness.

When my world came back into focus, and with my eyes still closed, I could hear Julie explaining to her brother, “It wasn’t you, Bro. There was something I didn’t tell you because I was afraid you might injure her. You’ll have to learn it though, so we’ll do it next time.”

“What?” he practically pleaded.

“Teeth clamped on her clit, but you’ll have to learn to pay attention to her, and take the cues from her as to how hard to bite. I knew when she grabbed my head and pulled me to her harder that she hadn’t hit the big one yet and she was desperately struggling to get there. So, I clamped down even harder, and that did the trick.”

“Wow!” Steve said in amazement.

“Wow is the understatement of the year.” I said while showing them both a very satisfied grin.

Julie crawled off the bed and announced, “I have to pee.”

When she was in the bathroom, I said to my husband, “You did really great for your first time. I’m sure you would have got me there if she’d told you what to do.”

“I’m not so sure. I probably would have been too afraid of hurting you, but now that I know, I’ll force myself to try.”

Until then, neither Steve nor I had noticed that Julie hadn’t closed the bathroom door. We could hear her pee splashing into the toilet, and she could apparently hear our conversation, because she called out, “Don’t worry, I’ll help him through it as many times as you want. Just remember, you owe me something.”

When she appeared after flushing the toilet, she crooked a finger to me to come in the bathroom with her. Once inside, she closed the door, looked me straight in the eye and whispered, “I want to feel his magnificant cock inside me.”

Her words shocked me enough that I couldn’t think or speak for a few seconds, but when I could, I told her, “I’m not sure he will agree to that.”

“So, you’re saying you’d be okay with it, if he agrees to do it?”

“I’m not sure. I mean ... after what we’ve already done today, I guess that’s not a big step farther—so yeah, I guess I don’t mind, if he doesn’t.”

“Good then. I’m going to take a quick shower while you go talk to him. When I come out, just give me a thumbs up or down so I’ll know.”

“Steve, Dear, you know Julie has opened up a whole new world for us today, even if she did have to drag us into it kicking and screaming. She’s given us gifts that will last for the rest of our lives, and she may even have more up her sleeve to show us.”

“She said you owe her something. What does she want?”

I took a deep breath and let it out slowly, gathered my nerve and then told him straight out, “She wants you to fuck her.”

His eyes shot open, “But she’s my sister.”

“Yes, she is your sister—the same sister you watched shave my pussy and then get me off with her mouth after you dared her to. She’s the same sister who taught me how to give you a proper blowjob and then helped me do it. I didn’t hear any protest from you about that. And she’s the same sister who you watched get a mouth full of your cum and share it with me. Oh, not to mention that she’s the same sister who just taught you how to eat pussy, and then got me off with her mouth a second time.”

His expression softened, “So, you don’t think me fucking her would be over the line?”

I let out a chuckle, “After everything we’ve already done, I’m not sure there is a line.”

“We’ll, in that case, okay sure. I’m a man with hard dick, and she’s a sexy woman. Why wouldn’t I agree to fuck her—that is, if you’re okay with it?”

I let out a wild giggle, “That’s my horny man.” It was just then that I glanced down and saw that my husband’s cock was standing straight up and twitching. As I was sliding to the floor and maneuvering myself between his legs, I told him, “I’m going to practice some of what I’ve learned today. When she comes out of the bathroom, just give her a thumbs up. She’ll know what that means. Just remember one thing.”

“Oh, what?”

I slid both hands around his massive cock, kissed the tip, and then grinned up at him. “I expect you to save some of this for me tonight. Pussy eating is one thing—one great thing, but it will never replace having this inside me.”

“Deal.”

I was very busy ‘practicing’ when I heard Julie come out of the bathroom. I glanced up to see my husband giving his sister two thumbs up. And I heard her exclaim, “Yummy!”

When I got to my feet, I realized that neither Julie nor I had touched the drinks we’d brought upstairs, and the ice was melted. I pointed that out to Julie and we immediately took up our drinks and headed downstairs.
