Part 1
I was 20, my brother 23. I pretty much left him alone, not really caring too much what he was into. I dated very little, always having feelings for men. To add to my confusion, I also liked crossdressing. I felt so confused until that day.
I came home from class pissed off. I just found out I would not be getting credit for all the work I did. My Professor who I had a crush on totally backstabbed me. ARGHH, my head was hurting. My brother and parents have 9-5 jobs, so I knew I had the house to myself. I went upstairs and slipped on my favorite lingerie, a black teddy with garters and matching stockings. It was then that I heard him. My brother was home, in his room. I recognized the noises he was making, I do the same when I masturbate. I opened his door slightly to peek in. It looked like he was trying real hard with little success, Hmmphh, amateur I thought, needs practice.
He looked good, I never noticed him that way before. Tall, thin but muscular. Gorgeous ass nice and round, but thin but perfect. His cock was a full 8". Now I was stiff and I couldn't take it anymore. I had enough shit today, I don't know what came over me, but I went in. He looked surprised to see me, especially dressed in lingerie. Before he could speak, I climbed on his bed and grabbed his beautiful cock. He was so stunned he couldn't move. "you look like you need help" I said. I started stroking his cock and all he could do was moan in ecstasy. I decided to go all the way and it seemed like he didn't care. I lowered my head on his cock. I've never done this before, but I knew how. The head of his cock swirled in my mouth as a sucked and stroked. I licked the shaft and even sucked on his bag. My head bobbed up and down as I sucked and sucked. I didn't quite know what to do because I am having so much fun. He was moaning and grunting, getting me even hotter. I could taste the pre-cum on the tip, and then he exploded in my mouth. My first reaction was to start swallowing as much as I could there was more than I could handle and some dripped down my chin and on his cock. It tasted so good, I never thought it would.
I crept up and lied down next to him, he still had nothing to say. I leaned over and started to french kiss him, sharing a little of that precious cum with him. He pulled away and said "I never knew". "Neither did I" I replied. I got up and went to leave, feeling good. I turned and said "don't tell anyone ok?" He replied "that'll cost you my little bitch, I'll be home early tomorrow too. You just got yourself a new boyfriend slut". Hmmmmm, a boyfriend? I feel so good right now.
Part 2
I couldn't wait to get home from school. I couldn't wait to see him again. On the way home I stopped and bought some condoms. I arrived home and went to look for him. Sure enough he was upstairs, naked and ready to go. He got up and we kissed passionately. I skipped the lingerie and started to undress. I stood there naked and rock hard. He held out a bag to me and said "my slut is going to need some special lingerie. Go put these on". In the bag I found some beautiful red lingerie. A frilly lace bustier with red stockings and patent leather shoes with a 5" heel. Excited I slipped the lingerie and the shoes on. I was surprised how easily I could walk.
I returned to his room to find him rock hard holding one of my condoms. "you look pretty" he said. "thanks " I replied. Looking at the condom, he asks "what's this for, you wanna please me like that?" "I'm not sure, I don't really know what I was thinking". He put the condom on and came towards me. We kissed again and he lead me to the bed. I noticed he had mom's tube of KY. I knew then that he already had this in mind. He told me to lay on my stomach with my ass in the air. He lubed my asshole and stuck a finger in. The pleasure coursed through my body like nothing I ever felt before. I let out a little moan of delight. "if you liked that, you'll love this; get ready" he said. I felt the head of his cock at the entrance to my ass. He pushed the tip in and it felt good. It slid in easily. He pushed harder and the shaft began to enter. Now it hurt. I let out a small scream, which turned into a loud moan. He was all the way in. He let me feel him inside me for a while, then he began to slowly fuck me. I began to moan louder and scream in delight. I begged him "fuck me harder, I'm your bitch, fuck me harder". I began rocking with him trying to slam my ass into his cock. He exploded inside me and we collapsed on top of each other. This time he lay down next to me and we kissed again. I was his bitch, his slut and I was happy.
