My sister is four years older than me. I am 18 yrs old. One of four kids. My sister Amy is a collage student. After our grandmother died she left us all a nice little trust fund. When Amy turned twenty one she bought herself a small starter house. A one bedroom, with a small front yard and a small back yard. I used to go over on weekends and we would hang out, watch movies and have a couple of drinks. One of the courses my sister took as an interest course was photography. She had converted part of her basement into a dark room and processed all of her black and white photos there. She had taken some truly lovely pictures.

One weekend when I had been invited over we had had a few drinks and she started to tell me about an assignment for her photo class that she was having trouble with. It was an expose of nudes and, do to a conflict in her scheduling, she was unable to attend the modeling session. She explained that she had tried to take shots of her self but was unable to get the lighting right and as the camera was on timer she did not like her poses as well.

I suggested that she ask her friend Sue to pose as she was a beautiful girl. Amy told me she had asked her and she refused. Amy said that she didn’t know what to do and that if she did not turn in the assignment on Monday she would get a zero.

I said “that sucks, do you want another drink?”

She said “sure I would love one.”

When I came back into the room the conversation moved on to other things. After a couple more drinks Amy asked me if I would do her a huge favour. I told her that of course I would. She responded that I should not answer so fast as it was a HUGE favour.

She then asked me if I would pose for her. Well my dick did the scared turtle thing and sucked right up inside me. I could not believe my sister wanted me to pose naked in front of her. I told her that even the thought of it made me nervous that I would not make much of a naked model as I would look like I just got out of an ice water bath. She laughed at this and said if I could just sleep on it and we would talk more in the morning.

The next day started out as a normal Saturday. We showered then went to a local greasy spoon for breakfast sharing sections of the news paper. We returned to the house put on some music and played some cards on the front porch. We started to drink sometime after lunch and over our first drink the question of the night before was once again broached.

I told Amy that I was still nervous but I would give it a try on one condition.

She asked “what condition is that.”

I told her if she was willing to show me the pictures she took of herself I would pose for her.

She asked if I wanted to have another drink, I nodded. She returned with two drinks and a bunch of photos but did not offer me the pictures. She told me she understood my reluctance because she did not know if she wanted me to see her pics. We sat and talked often breaking in to laughter which helped put us both at ease.

She offered me the photos a couple drinks later. As I looked at the photos of my naked sister I felt a familiar feeling between my legs and buy the tenth picture I had a full hard on. My sister noticed the bulge in my shorts and said, with laughter in her voice, so much for the ice bath.

Blushing I said “I’m sorry I did not expect that reaction.”

And she said she would have been offended if I did not have some kind of reaction.

We decided we would wait until it got dark so she could better use artificial lighting.

After dinner Amy set up her lights and cameras in the basement and chose a back drop she felt appropriate. I know it sounds like we drink a lot but very seldom do we get drunk. It was all I could do not to start to hammer the drinks back.

It was time. Amy said lets start slow so I could get use to the camera. She took pictures on her digital while I slowly undressed. When I was down to my boxers I realised the scared turtle was back and told this to Amy. She told me not to worry that most shots would not involve penis shots. I removed my underwear and Amy directed me into a bunch of poses that did not include penis shots. She was at this point using the black and white camera. She said she wanted to now take some full frontal nudes. I was still not relaxed enough for my liking.

First I don’t have an overly large cock. I’m just over average in both length and girth. I said that that afternoon seeing her naked really helped and since I was naked and I had already seen her naked would she take off her cloths. She said what the hell and undressed. Again seeing Amy naked I could feel the swelling start, but, do to my nervousness I did not have the same reaction, almost but not quite. Amy got some good shots and over all seemed happy with the session.

Standing naked in front me Amy asked if she could get some shots of me fully hard. I told her that I could not do that with out playing with myself as I was still camera shy. She said for me to go ahead. I told her I could not masturbate in front her, it was to embarrassing. She suggested we do it together.

Amy started to massage her breasts. Her breasts were not large but perky and nicely formed with nipples that were slightly high and just a little to the outside. I started to stroke my cock and soon became fully erect. Amy’s hand had moved south and her finger was slowly stroking between the lips of her pussy.

I had noticed that she was now using the digital camera with her remote control. She was watching me taking random pictures without lighting changes or even looking in the view finder.

I had to stop or I was going to cum. When I did this Amy asked what was wrong. I told her I was going to cum and had to stop. She smiled at me lowered her head and took a nipple into her mouth her other hand increasing in speed and force. Seconds later her head went back and she let out an extended moan. She looked at me and told me she wanted to see me cum.

I approached her with my cock in one hand and with the other took the hand that had been between her legs and put her finger in my mouth sucking it. My pace had picked up and I could feel my load building, about to explode. Amy placed her hand on the back of my head and brought my mouth to her erect left nipple. For me this was just too much. I was pounding on my cock and I had my sisters left nipple in my mouth. I could feel myself starting to cum and squeezed my cock really hard, trying to stem the flow. I exploded shooting cum on to both of our bellies, her right tit and my chin.

I looked up at Amy and said oh my god. She smiled, kissed me, then, licked my cum from my chin. Then she said next time she gets to get it right from the source. I smiled at Amy and said Lets get a drink and in twenty minutes you can do just that

Amy gave me a robe and put one on her self. We got drinks and went out to the back porch. We talked about the photo shoot and our mutual masturbation. Amy was saying that we should not have done that and she was feeling bad that she had not only allowed it to happen but that she had instigated it.

I said “well that sucks, I guess you won’t be giving me head tonite and sorry about the pun.”

This got a laugh from us both. Amy told me she didn’t think it was a good idea as we were brother and sister. After a few minutes of silence, both in our own thoughts, she said “maybe we could masturbate together again but that was all.” She suggested we go to the dark room and process the black and whites.

We started the processing and I drifted off to a far corner so I would be out of her way. I started going through some photos and came across some of Amy’s self portraits’. They were a lot more graphic than the ones she showed me. She had taken pictures of herself masturbating and using a dildo. Legs spread wide open and taking the whole length of this anatomically correct vibrator.

I was starting to get a hard on so I put the pictures aside and watched as Amy finished processing the film. We went upstairs and back out to the back porch with drinks in hand. We were talking and I told her I had seen the other pictures and thought they were really hot! She asked me to go and get the pictures so we could look at them together. I returned and we started going through them. As before I started getting a hard on but this time we continued to go through the pics. Before long I had a sizeable tent in my lap. Amy had noticed and had spread her legs and was toying with her pussy. I pulled aside my robe and started to stroke myself. Once again I took Amy’s hand and sucked her fingers. I asked Amy, ok pleaded, for her to put some of her cunt juice on my cock. She was reluctant stating that she should not touch my cock. I begged unabashedly. She finally relented and took her two cum covered fingers and rubbed my throbbing cock head. The feeling was electric. We were staring at each others laps while we continued to play with our selves. Neither of us was going at it hard, just playing and staring. Amy asked me to put some of my pre cum on her nipples which I did with great pleasure. I asked her to reapply her pussy juice to my cock. This time instead of just rubbing it on my head she grabbed my shaft and with two fingers and her thumb finger fucked the head of my very swollen cock. Her ministrations felt incredible and I closed my eyes and put my head back. I moved my hand and slid it up her thigh to her sopping wet cunt. As I touched her pussy I could feel my orgasm getting closer and closer. “Amy please take my cock into your mouth, I’m going to cum!” She didn’t say anything, she just moved between my legs and plunged my cock deep into her throat. That was about all I could take. She then did something I had never experienced before. With her mouth at the base of my cock she stuck her tongue out and licked my balls. That was it, I screamed out “wholly FUCK I’M GOING”. That was all I got out as I came with a force that over took my whole being. After I regained my senses, I looked down and into the eyes of my sister. I have to admit that that was one of the most beautiful sights I have ever seen. My still ridged cock, going slowly in and out of my sister’s mouth as we stared into each others eyes.

As I trembled with after shocks I took Amy’s head in my hands and pulled her up. We had a long, passionate kiss and I said “Ok Amy I don’t think I can top that but I’m going to do my best.”
