My cousin gives me some sweet riding on her less fertile days

My cousin, a hot chick with a wild side, loves to take control. On her less fertile days, she hops on, riding me doggystyle, her skinny body moving in perfect rhythm. She's all about pleasure, and I'm all about giving it to her. No strings, just pure, unfiltered fun. We both know the rules, and we play by them. It's our little secret, a thrill we can't get enough of.
