My slutty sister came home from school one afternoon. She started going on about her new sexual education class she’s been taking at school. Amazed, she started listing all the new sex positions she learned about and how she couldn’t wait to try them. She was without a doubt enthusiastic about it until she started begging to show me. I was not in the mood but I couldn’t say no with the look on her face. She came out in a cute light pink lingerie set, pull them to the side, and sat all the way down on my throbbing cock. After, she puts my legs up, riding me, ass up, until I almost cum. Lastly, she sits on her shoulder with her legs all the way up so I can pound and squat my dick inside of her tight wet pussy as hard as I can.
