A few years ago I was home for the summer from college, and I was up late drinking vodka with my 18 year old little sister. We were both a little tipsy, but not too drunk. We were watching a movie together when we heard my mom and her boyfriend having sex in her bedroom. we could hear our mom moaning loudly, and decided to sneak up to her door and see if we could see her in action. We slowly opened the door just a crack and looked in at our mom. We had to lean pretty close together so we could both see in. we saw our mom on all fours getting fucked hard from behind. My cock instantly started getting hard, and my boner was pressing right into my little sister's ass through her jeans. She felt my dick pressing against her, and reached back and started rubbing it. I was so horny that I started rubbing her pussy through her pants and squeezing her huge soft tits. Then she reached down my pants and took my cock in her hand, and led me down the hall to her room. Once there, we both stripped as fast as we could, and she pushed me back onto her bed. Then she started sucking my dick, and her tongue felt great on my throbbing cock. After a nice quick bj, she climbed on top of me and slid my dick inside her pussy. She was so wet I couldn't believe it. She bounced up and down on my cock for awhile, then told me she wanted me to fuck her from behind like we had seen our mom getting fucked. I pounded her pussy hard and long, and the sound of her moans drove me crazy. when I was ready to cum, I pulled my dick out and blew a huge load all over her sweet round ass. She told me I had the nicest cock she'd ever had inside ofher, and ever since then we fuck at every chance we get. I love having sex with my little sister, but I have no plans on getting her pregnant. I just love the way her pussy feels wrapped around my cock!
