Sunday, May 14th
I guess I am your average fifteen-year-old boy growing up in a loving family. I have fantastic parents and even love my four siblings. Now I’m not saying everything is roses and puppy dogs, but we are a happy family.
My name is Eddie, I just turned fifteen yesterday. Like the rest of my family. I’m not bad looking and in excellent shape. I play baseball and football for my high school, junior varsity this year. I love running and lifting weights, which is a family trait passed down by my parents. They are kind of fitness fanatics, although not at the sake of all else. They had us exercising in one form or another since we were crawling. We have a home gym set up in our basement, complete with two treadmills, a stepper, stationary bike, Olympic weight set with lots of dumbbells and a multi-station weight machine. We all spend several hours a week using them, often with the whole family together.
My parents started a family almost right out of high school where they were sweethearts. My mom and dad are 38, although my dad will be 39 next Sunday. They look younger and no one believes they could have teenage kids, but they have five of us. My older sister is 17 and I have a 16-year-old brother. I also have two younger sisters who will be 14 in two weeks. They’re twins, but fraternal, not identical. They look somewhat alike with light brown hair and brown eyes, but other than that, not very much. Patty is an early bloomer and has 32B breasts (I snoop in laundry baskets), while Katie is 30A only so she doesn’t have to say she wears a trainer anymore. They both have hope of getting fuller figures like my sister Julie (34D) and mom (34C).
My parents also encouraged us to have pursuits outside of fitness and athletics. My sisters all play musical instruments and my brother is just into music and has a very extensive collection. I draw and am told I’m pretty good at it. Once each of us found our passion, so to speak, they tried to give us all the tools we needed to pursue them. My sisters got high quality instruments, private lessons and in the summer attended musical camps. My brother, Tommy, got a high-end stereo system and lots of music gift cards. I received lots of sketch books, pencils, easel and for my latest birthday, I also got a top-of-the-line digital camera with loads of attachments and a printer capable of printing high resolution photos up to 13x19.
It may sound dumb to get a camera when I love to draw, but I mostly draw from pictures I take. That had been with an old Polaroid, but quality wasn’t great, pictures had to be small and film is about impossible to get anymore. Now I can get much better definition and larger prints to work from.
I suppose I should tell a little more about my parents so later things make sense. I mentioned they were fit, but they’re both gorgeous, yeah even my dad if my sister’s friends are any judge. My parents, Carl and Samantha (Dad and her friends call her Sam), could be one of those sexy Hollywood couples splashed all over the tabloids. She’s about 5’5”, 105lbs., shapely behind, nice breasts, beautiful face and in general, a fit tan body. I feel bad to say this, but with the exception that Mom’s boobs are real, she looks a lot like porn star Cory Chase, especially when she’s dressed up and wearing her glasses. Remember, I just turned 15 and she may be my mom, but she’s also been the focus of more than a few loads of my boy juice I’ve shot into tissue.
Now about Dad, he’s a stud. He doesn’t say that, but Mom, my sisters and their girlfriends all say he is. He’s 6’2”, about 205lbs., nicely muscled, but not muscle-bound, has washboard abs, just the right amount of hair on his chest and his face has chiseled features. Even my dad’s voice is sexy. He could do late night radio and have all the girls swooning.
I have been raised seeing my parents openly show their affection in kissing and touching each other, pretty much every time they’re in the same room. It’s usually tame, but there have been occasions, mostly since we’re all teenagers now, that I’ve seen dad grab her ass or squeeze her breast briefly and her grabbing his butt and even giving his cock a quick grope. Kisses are seldom quick pecks, but are usually involving lots of tongue and some moaning from mom. There have even been times when one has dragged the other to their bedroom and told us to order pizza for supper. After an hour or so, they come out to join us and appear to be very hungry and happy. In general, we see daily how crazy in love our parents are with each other. That’s the environment I’ve been raised in.
I should also mention the pool and hot tub out back as we spend a good amount of time out there, now that it’s mid-May. My mom and sisters have all been tanning in their skimpiest bikinis for a couple weeks now. I could lie and say I don’t notice how sexy they all look, even my younger sisters, but I think you’d see through me.
Having told you about myself and my home life as it is, I must say my life was about to change dramatically. I could not have imagined it in my most erotic wet dream or my scariest nightmare. It all started with that new camera and my teenage libido. I suppose the change to warmer weather and the females of the family desire to have great tans this summer may have also been contributing factors. Of course, let’s not disregard dumb luck, both good and bad. So, back to the camera and my constantly raging hard-on...
Since opening the present, I had hardly put the camera down. That night I hooked up the printer, tried it out with a stupid selfie and read the manual cover to cover. I took pictures around my room, then the house and even went outside to see about taking pics in low light. By then the sun had gone down and soon I had to get to bed as it was a school night. I set the camera bag where I could see it when I woke. Remember, I’m still a kid and this was the coolest present I ever got!
I will confess that I got home as early as I could for the last two weeks. Until suppertime, there were always sexy bodies sunning around the pool and not always family. I usually had baseball practice, but still had time to go to my bedroom, which overlooked the backyard and survey the lovely ladies in their natural habitat. I would also masturbate like a mad man imagining them taking off those little strips of cloth and oiling each other up. I never lasted very long picturing my sister Julie and her friends slowing working oil into their young firm tits, tweaking their erect nipples and even running their fingers down to their bare pussies. In my mind they were devoid of any hair, although I was only basing that on how tiny their suits were.
As I kneel in front of my window, erection in one hand, tissue at the ready, watching my mom, sisters and their friends enjoy our pool, I furiously stroke my cock. It won’t come as a total shock to anyone that I’m still a virgin. I suppose I’m good looking enough and my cock compares very well with my peers, but I don’t talk very easily to females. Especially if they are attractive and that’s compounded when they are scantily clad. I don’t just mean a bikini, but even some of the summer outfits these girls wear. My Lord! I have trouble not popping a boner just seeing a nice body in tight shorts or a tank top, and if there is no bra present, I’m lucky not to cum in my pants.
Like most fifteen-year-olds, I’m always thinking about girls/women. I’m not even sure what to do, although I have watched plenty of porn. I shouldn’t say I don’t know what to do, but more how to do it so I get a second invitation. It’s a scary idea in my mind that I’ll get my chance with one of my sisters hot and popular friends and screw it up. After which everyone would find out and I would be a laughing stock and need to run away to Tibet or something. That fear can consume me around a pretty girl, so I’m here jacking off, looking out my bedroom window, instead of being down at the pool offering to be the oil boy for all of them.
So, after I’ve shot my second load into the mouth and all over the tits of my sister’s friend Diane ... oops, I meant to say into the tissue in my other hand, it’s time for homework and then a good work-out. Such are my evenings during the week, but truth be told, my weekends are quite similar.
On Tuesday, I was lucky because practice was cancelled and mom was home. She doesn’t work Tuesdays. She’s a surgical nurse for a group of surgeons and they take off Tuesdays. So, another turn of fate was that no one else was home yet and wouldn’t be for a good hour. She was out at the pool in a very small bikini, glistening from sweat and oil. I ran to my room, took up my usual spot and imagined her looking up and waving for me to come down. There goes the first load.
I would go down and see what she wanted and it would involve applying oil after removing her suit to keep from staining it. I would be allowed to massage the sunblock into her gorgeous breasts, running her nipples through my fingers. She’d notice my mammoth erection (it’s certainly mammoth in my fantasy) and reach for it, telling me to remove my shorts and let her see it. Once again being the obedient son, I oblige her and she starts to apply the oil to me. She starts stroking it and in no time, I am blasting cum on her face and chest. She even kisses the spunk covered head before letting go. There goes the second load.
The internal conflict I have is she’s my mom and I shouldn’t be thinking like this. Even more so is she’s my dad’s wife and I would never do anything to hurt him. The other half of me would simply love to play with her tits while she jacks me off. I think we know who usually wins.
Now I’m sated and still home alone with mom and she’s laying there wearing less than her underwear, and I have a new camera with attachments like a 75-200mm lens. Time to try out my new toy.
I set up the tripod and mounted my camera to it. She was laying on a lounge out in the sun, sunglasses on while reading a book. I could focus fine on her, but the book and her arms were blocking her wonderful breasts enough to ruin the view. I suppose I could yell out the window for her to put the book down, but as I took sample pictures, I decided yelling might not get me what I was after.
I downloaded the handful of pics and the quality was really nice, but it just didn’t accomplish what I wanted. I sat there and debated about going downstairs and finding a place to discreetly take better pictures. but getting caught could create problems I didn’t want in my life. It also would be embarrassing as hell and would probably label me as a complete perv with my mom and sisters, and likely my sister’s friends.
As I sat there pouting about not getting the jack-off material I had hoped for, it hit me. My dad’s birthday was this coming Sunday and he would love a picture of his sexy wife to frame and that was why I got the camera. How could she tell her young son “no” when it was for a birthday present for her adoring husband? Camera in hand, I headed out the pool.
As I came through the slider, mom looked up from her book and said, “I didn’t think you’d be home this early.”
“Yeah, I wouldn’t be, but coach had something come up and cancelled practice.”
“Why don’t you get your trunks on and take a dip in the pool?” she asked.
“Well, I came out to ask you to help me with something.”
“And how my I assist my favorite artist?”
“You could pose for me,” I said maybe a little too quickly.
She sat up a little straighter and looked at me over her sunglasses with a raised eyebrow.
“Why don’t you tell me exactly what you want me to do and then I’ll decide.”
“You know dad’s birthday is Sunday and I still don’t have anything for him. I thought he’d enjoy a high-quality drawing, suitable for framing, of his beautiful wife. I could also give him a collage of several of the better photos he could put with the sketch.”
She gave me a considering look and took just a minute to say, “Okay, I can help you out.”
“Thanks, mom.”
“What do you want me in and where are we going to do this?”
“I thought what you’re wearing would be awesome. I’ve heard Dad mention how good you look in your swim suit, so I think he’d really like you in it,” I explained with my fingers crossed.
“Your father isn’t very shy about saying things like that within earshot of you kids. It used to bother me until your sister, Julie, told me it made her feel good that her parents openly talked like that. She thought it showed we loved each other.”
“All us kids have talked about that and we all feel like Julie does. We kind of like hearing you two talk about each other like that and we are all teenagers. It’s not like we’re little kids anymore,” I explained.
“The fact you are all growing up is not lost on me. It makes me feel older every time I think about it.”
“You don’t look old. Guys check you out whenever we’re out together and girls hope they look as good as you when they get older.”
“That’s lovely of you to say, even if I’m your mom, but if you want to do this we need to get going. I’ll need to go in and start supper in twenty to thirty minutes, plus your brother and sisters will be home by then and I’d prefer not to have an audience. So, tell me what to do.”
I paused for my mind to run a quick inventory of the poses I imagined as I stroked my dick daily, but then decided to treat this professionally or at least with a minimum of perversion.
“If you don’t mind, I’d like to first have you walk to the far end of the pool and then back. Just walk normally,” I said, again hoping she didn’t ask me why.
She just got up and adjusted her suit, an act that was erotic by itself. As she primped, I turned to video on. I can take stills even as the video recorder runs and I wanted everything I could get.
She looked at me and asked, “Ready?”
I nodded and she walked to the end of the pool, pausing only for an instant before turning and walking back. I took about twenty pictures in the minute it took her to perform this maneuver. I knew both dad and I would enjoy the results of this exercise.
“Now can you lay back on the lounger? No book this time, just make like you’re asleep in the sun.”
She bent over, facing away from me to adjust her towel and small pillow. Thankfully the camera also had a setting for silent picture taking, no annoying clicks. I racked off about twenty more as she bent over with her delicious ass sticking up and her legs straight. I knew I was going to hell for the thoughts I was having. Once she got settled, I took a few shots and then had her put one arm over her head, then had her bring one leg up, so the knee was up.
I figured I’d see how much I could stretch things before she told me that was enough.
“Mom, can you roll over on your stomach now?”
She did and had her arms above her head as I clicked away. Her suit bottom had pulled more toward her crack and well over half of her cheeks were bare. I was mesmerized and kept taking digital memories.
Now I went for broke. “Mom, you should untie you top because all you girls do when you’re tanning.”
She did it without hesitation!
“I hope you don’t get offended, but would you take the top completely off and drape it over the arm of the chair? I’ll turn my back until you lay back down. I just think it will be a visual dad will like”
She got up a little turning to me, holding her top in place, and said sarcastically, “Oh, your father will like it?”
“Well, turn around,” she instructed.
I kept the camera pointed behind me and I did as I was told. I just knew I would be beating my meat until my arm gave out later.
“Okay, you can turn back around.”
She had done as I asked. There she was with only a skimpy bottom on, her top hanging off the arm of the lounger. Her arms were crossed under her head and her ample boobs were peeking out from her sides. I was staring and almost forgot what I was doing. Once I got around to taking the desired shots, from multiple angles I let her know my last requests.
“Thanks mom, these pictures will be a great gift. There are a couple more things, if we still have a few minutes.”
She quickly pointed out, “You know I’m not taking anything else off.”
“Oh, I know. I was thinking you could turn around and sit like you were, but cover your breasts with your hands. After a few pictures like that, you can get your top back on and I want a couple shots coming out of the pool.”
All she did was say, “Turn back around.”
I again turned around and kept the camera recording behind me. I was so excited; I was worried all the video and pics would be blurry.
“Okay,” she said, waking me from my daze.
As I turned to look at her, I almost came in my shorts. There she was, one leg straight out, one bent up, her black bikini bottoms dipping low to what must be below her pubic hair line. As I followed her taut stomach up to her chest, there they were, her full naked tits ... with her hands covering her nipples. She was kind of mashing them out and hadn’t bothered to put her sunglasses back on and was staring into my eyes. She gave me a minute to compose myself. After what felt like a very long time, I raised the camera and started taking pictures as I moved around to her side.
“Last thing is to get the top back on and jump in the pool. I want you to come out of the water and fling your hair back, so the water throws a rooster tail. After I get that, then I just want you to get out using the ladder and looking up into the camera lens. Those are the last poses, if you don’t mind.”
The whole time I was talking, she was still holding her breasts and I was looking at them way too much. I wanted to keep talking so she couldn’t get dressed, but I thought I had already pushed the envelope.
“Alright, assume the position.”
I again turned until being told I could look. She walked past me without telling me I could look and dove into the pool. I readied my camera as she broke the surface of the water and flung her hair back. I had her do it four times before I got what I thought I needed and then had her move to the ladder.
She waited until I was set and then looking in my eyes, got up out of the water. I had her do that three times just because it was a view to savor. I am a fifteen-year-old boy after all.
As I took my last shot, I handed her the towel I had set aside for her to use.
“Thank you for being such a great sport and helping me out. I just know dad will love what I give him.”
She smiled as she padded her body dry, “I better not find any of these pictures on the internet.”
I smiled and said, “Certainly none of the sites a fine upstanding woman like you would visit.”
She just smiled, grabbed her stuff from the lounger and headed into the house.
I followed her inside, which was a wonderful experience and headed to my bedroom to download the camera. It turned out to be even better than I had hoped. The resolution was incredible!
I stored the pictures in one file, plainly named. Then I moved the video to a password protected folder with a completely innocuous title. I had time so I played the video and fast forwarded to see if I gotten the shots I really wanted. I hadn’t pointed the right way on the first and second attempt, but on the last one, when she was topless and taking her hands away to put her top on, I got a well centered shot of her tits. They were exceptional! Large, round, smallish areolas, and nipples, and amazingly firm. They were obviously real, but only had a minimal amount of sag. I couldn’t help but masturbate. Between seeing her topless and spending a half hour photographing her, I exploded almost immediately.
Shortly after I got cleaned up and sanitized my camera and computer screen, I was called down to supper. I would never look at my mom the same way.
After supper, I went back to my room and started looking through the photos in earnest. It would look pretty bad if I didn’t give dad the present I had talked to my mom about. I figure she was already a bit suspicious about my motives for taking pictures of her in her little bikini, but ultimately let me do it for her husband.
I went through all the pictures once and took out about fifteen of the best, both for composition, as well as their hotness factor. By the time I was through looking at all of them, I had to jack off again. I dropped my shorts down to my ankles as I was running the pictures again, but in a slide show. I was on such a sexual high the whole afternoon that even though I had masturbated several times already, I still fired a good load into the ever-present tissue.
After I relieved myself, again, I whittled the pictures down to six amazing shots. They were amazing more for the model than for the photographer’s expertise. I had one each of walking towards and away from the camera, one of her bending over fixing her towel on the lounge, one of her laying on her stomach with her naked breasts pressing out her sides, one of her sitting with a hand bra and one of her climbing out of the pool. As incredible as her body looked in all of them, it was her facial expression in each that caught my eyes.
I had already mentioned how beautiful my mother is, but these pictures brought something out I had never seen before. I don’t know if it’s always there or she just wanted to make these good for dad or if there was something else. Regardless, if all I did was photograph her face, men would still get hard-ons looking at it. She had a sensuality about her, a look that said if you could meet her high standards, she’d rock your world. All that was left to do was arrange the six finalists into a design I could print out, which didn’t take a lot of time. I printed them at the 13x19 size and in the best quality.
The print was exceptional. Now I could look at all six and pick which one would get drawn. It really wasn’t a contest. I had two basic considerations, the sexiest and would it be appreciated as being drawn by their fifteen-year-old son. I chose the hand bra pic. It was still conservative enough and had both her full body and her face, as opposed to the butt shots that were sexy as hell, but maybe a bit over the top or a little too naughty. I did love the one of her getting out of the pool, but it was shot from above and didn’t show her entire body, something I wanted to do from the start.
Something I didn’t notice until going through all the pictures in detail, but one of the pictures looking down on her as she climbed the pool ladder, my hard-on was in the picture. I suddenly realized if it was that prominent to get caught in that picture, then she certainly saw it and possibly could have looked up the leg of my shorts and seen even more of her son’s cock and nut sack. I sat there and could feel the blush go over my entire body at first, but then the pervert in me took over and imagined she wanted to see it and enjoyed that I got an erection looking at her body. I eventually settled on that she was probably amused and understood fifteen-year-old boys get erections about a hundred times a day. I was still embarrassed when I thought about it.
The only picture I vacillated over was one with the rooster tail as she emerged from the water. One of them was near perfect with the water creating a circular wall above her, her arms were slightly back and her chest out. As good as it was, I thought it didn’t fit this project, but I decided to draw it on its own and give it to mom as a thank you for letting me photograph her. You never know when you might want to take more pictures, so keep the model happy.
I printed both the rooster-tail picture and the hand-bra pic as big and clear as I could. The former I put in a folder and placed in my desk for later, but the hand bra I started drawing. I was going to give dad a 16x24 sketch, so I set up the scale on my easel by just getting some outline of the drawing. This took me a while, but when I was pleased with it, I figured I’d put it away and finish after school tomorrow.
Speaking of school, I still had at least an hour of homework for tomorrow and being an excellent student, part of the deal for getting all the other stuff, I would get it finished before I went to bed. Needing to get on it immediately, I of course opened the computer back up and got mom’s topless picture on my 21” monitor and spanked the monkey one more time. Let me tell you, the monkey was getting tired and sore, but I still couldn’t stop myself. That was five times since school, six if you count the one in the shower this morning. If I kept up this pace, I’d be growing calluses on my dick before much longer or I would simply wear it out. I hoped exercising it regularly would help build the muscle ... I read it on-line so it must be true.
When I woke in the morning, my cock was rock hard and was already oozing juice into my boxers. I decided moving right into the shower, so I could piss without missing the toilet and jack-off while cleaning my sticky dick, would be a good start. I think it took longer to piss than cum and I was lucky not to bump into any of my sisters on the way there. Having my cock sticking straight out and a big wet spot on my boxers is not how I want to meet one of my sisters ... or my mom for that matter.
I got all my morning necessities out of the way and headed back to my room in a towel. I forgot my robe as I was in more of hurry than normal.
My sister Julie saw me and threatened, “Oooh little brother, going for the sexy look this morning. It would probably look better if you just dropped the towel.”
She hesitated for only a second before reaching for my towel and starting to pull.
As soon as I felt her start to tug, I panicked a little. Holding on for dear life (If I knew what I know now, I’d have let her pull or at least called her bluff) and at the same time, I kinda yelled like a little girl, “Stop it!” Big Mistake!
At that first squeal, my twin sisters hit the hallway, followed only a couple seconds by my brother. No one was my ally. Next thing I know, I’m down on the floor with a death grip on the towel. Most of my ass is already hanging out and I am trying to salvage what dignity I can, which really is not much at this point.
As I begin to think they’re all getting bored and about to leave me alone, my two little sisters start tickling me. That’s it, I’m done! I am a basket case when tickled. I can’t help it and they know me well enough to hit all the right spots. I lose the towel and can’t even control my arms enough to cover my junk with a hand or two. This is the time when my mother comes up and finds me sprawled naked in the hallway, giggling my fool head off.
The next thing I hear is one of the twins in a bit of an accusing tone, “Mom, Eddie got a boner!”
I didn’t realize it, but there it was for everyone to see, Eddie’s boner. I suspect I was red enough to look sunburnt at that statement.
My mom tried not to laugh, but she couldn’t help it and as she was also trying desperately to be stern, she instructed, “Julie give him his towel back and the rest of you get ready for school.”
Still snickering, Julie threw me the towel. I immediately placed it over my groin and stood, not caring my behind was still exposed.
Mom asked, “Eddie, are you alright?”
“Yeah, just embarrassed.”
She then surprised me with, “From the looks of it, you have nothing to be embarrassed about. It looked quite lovely”
As I froze in place, she turned and went back downstairs. My hard-on strained to get even harder. The idea that my mom saw my hard cock and thought it was lovely got my fantasy machine cranking at full capacity. My gorgeous mom, who let me take pictures of her in a skimpy bikini, thinks my erection is lovely.
Yes, I masturbated again before dressing and heading downstairs for breakfast.
My day at school was not memorable. I’m not sure if anything happened in any class because I was in a daze thinking about my lovely cock. I wondered if she was just saying that to give me confidence or if she really meant it.
I suppose I could take a survey of the cute girls in school.
“Hey Cindy, check out my erection. Do you think it’s lovely?” Probably not the best approach.
Maybe I could talk to Julie. Word is she’s spread her legs for quite a few people at school. I’m not judging, but word is she’s easy. Of course, the way guys brag, she might still be a virgin or she’s fucked the entire varsity football team or it could be somewhere in the middle. It’s probably best to be delicate when asking her. Don’t just go up to her and say, “Hey Julie, I hear you’re the school slut and have seen a variety of erections, so I was wondering if you think I have a lovely cock?” Maybe I’ll wordsmith that a little before I talk to her.
When I got home after practice, I spent ten minutes reviewing mom’s pictures on my computer, strictly from an artist’s standpoint. I could only work the keyboard one handed as the other was furiously stroking my stiff cock. Once I drained all that nasty spunk from my system, I headed to take a shower. This time bringing my robe.
