We had fondled each other during sleep overs. Guy was slim and I was somewhat chubby; my breasts were large. One day he asked me over to his house to ...have some fun." When I arrived, Guy was in his bedroom wearing a light blue shorty nightgown and panties that belonged to his mom. I undressed completely and climbed into the bed. We kissed getting more and more passionate. I had never even kissed a girl before, much less another boy. It seemed so natural to me as we french kissed. I did not know. I gulped knowing what I was doing but the fact that she was perpetuating it was incredibly arousing. I stood up and caught up with her in only a few strides. My mind knew what we were about to do and my cock was reacting with an intensity I haven’t felt in a long long time. I held our my arm to her and she took it and hugged it as we walked to the fence gate that opened to the back yard.She punched in a key-code on the keypad and the lock clicked. I pulled the door open and let her through then. I had my arms wrapped around her as she did this, she then lifted herself up and began moving a little more. Her eyes were shut at first as she bit her lower lip. The movement then started to pick up even more and she was back to her heavy breathing and slight moaning. I took my hands and cupped her tits into my hands slightly pinching those little nipples. I held as still as possible letting her do all the work, I wanted her to practice because there was no way in hell I would just fuck her. I then decided I had to taste her again. I jumped out of my bed with a pure adrenaline rush and busted into her room. She looked alarmed but as soon as she knew it was me, she turned back to her cam and continued to fuck her tight pussy with her dildo. I smiled at her before climbing on her bed with her. I then removed by bra and moved over to her amazing boobs.I took her left nipple into my mouth and sucked like I had wanted to since I did it the first time. I then moved my fingers towards her.
