My name is Mark. I am 22 years old and I live in a big house uptown with my two sisters. Our parents died in an accident two years ago, leaving me in charge of the family. Our uncles offered to let us move in with them, but we refused to leave our home. My sisters and I were very close even before the accident and now more than ever. I am a couple years older than Tracy and Kelly is the youngest. Both girls are very pretty and sexy. I admit that in the last few months, as I'd watched them go around the house wearing only t-shirts or nightgowns, I had wondered what they would look like naked, or how would it feel to touch their soft bodies. I never suspected that my opportunity to find out was in the very near future.
It all started when I was walking past Kelly's room and I heard some quiet moaning coming from inside. I could easily imagine what was going on and I carefully opened the door. My little sister was lying on her bed completely naked, fondling her pussy with one hand and rubbing her tits with the other. She was unaware of my presence; completely drowned in her senses.
I stood there quietly for a while, admiring her beautiful body. Her skin looked so smooth and tender. She was thin and her breasts were rather small but they had a shape and size just right for her frame. Her ass was another thing; it was perfectly round with no tan lines. With this magnificent body, combined with her angelical face, she had nothing to envy from any magazine model. I walked out careful not to make any noise and closed the door.
Twenty minutes later her room door opened and she walked out dressed in a long t-shirt, white panties and nothing else. She walked down the stairs and joined me in the living room to watch TV. She had a look of satisfaction in her face.
"Hi!" she said.
I just smiled back at her. As I changed the channels, I stopped at FTV channel (fashion TV) and there were some teenage models posing in bikinis on a beautiful beach. They looked gorgeous, of course, but no better that my young sister, so I asked her,
"Have you ever considered becoming a model?"
"What? Me? A model?" she asked back.
"Sure! Those girls look no better than you."
"Do you think so? That would be really cool! Travel to all those places for free!"
Then I said, "Hey, I just bought a digital camera, would you like me to take some pictures of you? Later we can load them in my computer and put them in a slideshow, so you can watch yourself posing like a model".
"Yes! Lets do it!" she said excitedly.
"Ok. Follow me"
My sister Tracy was out for the weekend so Kelly and I had the house to ourselves. We went to my room and I pulled my camera out of its case.
"Stand near the window," I said.
She walked in a sexy way, looking back at me. She leaned on the window, smiling at the camera and lifted her left calf a little bit. I started taking pictures. Her sensual moves and positions were turning me on.
"You look beautiful. Nice butt" I said. She felt ashamed and looked down. "Come on! If you want to become a model you have to be shameless. Make love to the camera!"
She just giggled and said, "Ok".
"Why don't you change your clothes? Put on something sexy."
"What should I wear?" she asked.
"Anything you want."
She ran to her room and after a few minutes she came back wearing a white blouse and a short skirt with black shoes.
"Now, let's take some pictures of you on the bed" I said.
She sat on the bed and I started shooting away, "Move your hands over your body".
"What?" she said surprised by my request.
"Move your hands like the models we just saw on TV."
She hesitated for a second but then she started to slide her hands over her legs and arms. I kept taking pictures and let her move at her own pace. Then, she moved one hand over one of her breasts and closed her eyes.
"Yes! Like that! This is perfect!" I said loudly.
This seemed to loosen her shyness a little because then she began to caress both of her tits and looked to the camera with very sexy eyes.
"Wow! You were born for this!" I said and she gave me a big smile.
I noticed she was not wearing a bra so I said, "Undo the top buttons of your blouse."
She did it without hesitation. She unbuttoned not just the top but all of them. Her blouse was still tucked into her skirt so her naked breasts were just barely visible as she moved from one position to the other. This was incredibly sexy and I was really horny.
"Lift your skirt a little bit," I said.
My young sister was obviously excited too, because she lifted her skirt almost all the way to her panties. I took pictures of her perfect legs. "You have the most beautiful legs I have ever seen," I told her.
"You mean it?" She asked.
"Sure. Let me see them with more light. Why don't you take off your skirt?"
She hesitated for a second, but then she pulled it down to her feet and a second later, she was standing in front of me wearing just her white panties and her open blouse.
"You are so damned beautiful. Now lay on the bed and keep moving," I said.
She did as told and with her blouse now opened freely, her creamy white breasts became fully exposed as she shifted from one position to the other. I didn't waste the opportunity and captured everything on the camera's memory.
After a long while we both got tired and finished the session.
"Did you like being a model?" I asked.
"I loved it! Let's look at the pictures!" she answered.
I downloaded all the pictures to the computer and set them up in a slide show, ready to be displayed sequentially, after hitting the enter-key. Kelly glowed with enchantment as she watched herself semi-naked on the screen.
"Ok. That's it for today. Maybe we can do it again tomorrow".
That night I could not stop thinking of that gorgeous young body posing only for me. One question was going through my head and I didn't know the answer to it... Given the opportunity, would I be capable of fucking my own sister? Well, it didn't matter anyway because the chances of that happening were very remote... weren't they?
That night I looked at the pictures over and over and I ended up jerking off so I could catch some sleep. But I was not the only one. When I went for a glass of water and passed outside my sister's room, I again heard moaning coming from the inside. I felt an irresistible urge to peek inside but the house was too quiet and I was afraid that she would catch me this time, so I didn't. I listened to her moans until she finished and then continued my way to the kitchen.
The next afternoon, after Kelly arrived from school, she knocked on my door.
"Can I see the pictures again?" she asked timidly.
"Sure, come in," I said. "I don't have another chair but you can sit on my lap."
"Ok," she responded gladly.
When she sat over me, I could smell her delicious perfume and that made my dick swell noticeably. I though that maybe having her sit on my lap was not such a good idea after all, since she could easily feel me getting hard inside my pants.
I started to display the pictures at random order, pausing longer on the most revealing ones. Kelly looked at each picture and then looked at me each time with such an angelic face that I felt the urge to throw her to the bed and fuck her brains out right there.
"Mark, do you really think I'm pretty?" Kelly asked.
"You are not only pretty, you're gorgeous," I said.
Kelly smiled and gave me a big kiss on the cheek while she put her arms around my neck. Then she rested her head on my shoulder and I took the chance to put my hand on her thigh. Then, with her head still resting on my shoulder she asked,
"Mark, what's a gangbang?"
I was taken by surprise by her question and I only responded, "Why do you want to know that?"
"Well, when I asked my friend Laura if she was still a virgin, she told me that she wasn't and that she had even participated in a gangbang with her boyfriend and other guys. I had no idea what Laura was talking about so I changed the subject," Kelly responded.
"Well," I said, "a gangbang is when a girl has sex with several guys at the same time"
"What? Do you mean one right after the other?" she asked.
"No, I mean at the same time," I responded.
"But, how do you do that?" she asked.
"I have some pictures of a gangbang if you want to watch how it's done," I said.
"Yes! Show me!" she said agitatedly.
I searched for the porn pictures I had stored in the computer and opened the first one. It was a picture of a beautiful teenager, with black hair and blue eyes, sitting fully dressed on a sofa with five guys sitting and standing around her, also fully clothed.
"First answer me something. Have you seen a naked man before?" I asked Kelly.
