Recap from pt 2: sis and I came home drunk Friday and she wanted to fuck me but I told her I wouldnt take advantage of her. Saturday night I came home drunk and she wasn't, and started begging to at least suck my cock. "just close your eyes and pretend I'm Amanda" By this point I was pitching a full tent and her hand was migrating to the button of my jeans. I didn't say a word as she popped it open and pulled on the zipper. Her eyes moved from my cock to my eyes and I nodded lightly. "I'm going to take real good care of you big brother" she said as she reached in and grabbed my cock firmly. I gasped slightly as she squeezed harder and rubbed it a little. In no time she was on her knees in front of me, pulling my pants down. My 8" cock sprang out and her eyes opened wide "it's bigger than I thought!" she immediately inhaled the first few inches of it and I gasped for air. If I wasn't drunk I might have exploded in her mouth instantly. I'll never forget her cute face gazing up and me as she gently sucked my cock. Slowly in and out, savoring it as much as she could. After what seemed an eternity, but was probably 5 minutes she picked up the pace. Bobbing her head as fast as she could. Pausing occasionally to tease my head as she stroked my full length as fast as she could. A few minutes of this and I moaned "you're gonna make me cum". She looked back up at me "mhm" she said without ever taking me out of her mouth. She went into overdrive and I immediately started cumming in her mouth. She kept sucking and stroking, taking every drop. As my cum started slowing, so did she. Gently cleaning every last drop as I finished. I sat there panting and shaking as she kissed the tip of my cock. "now I see why she likes you so much" she joked as she stood up. She pulled her shirt off, exposing a beautiful black and green push up bra. She used her shirt to dry my cock and balls of gently then simply said "goodnight" and went to her room. I sat there in a haze of drunkenness, ecstasy and disbelief for about 10 minutes before I could compose myself enough to get to the bathroom and then into bed.
