I knew my step-grandparents were excited to have me spend the weekend with them for Grandparents' Day, but I didn't know how much. I realized what I'd gotten myself into until my step-grandma started stripping for me while my step-grandpa was talking to me! Sure, he didn't notice, and her body was smoking hot, but I didn't know if that was better or worse. She went underneath the table and sucked my cock dry like a pro! I guess she learned a thing or two in all her years of experience, and I could feel it in every inch of my body.
Later at night, she sneaked into my room, looking more tempting than ever. How could I not fuck her when she was craving my dick so badly, and her tits were so massive! I don't think I've ever been that hard. The only thing that wasn't letting me enjoy her as I should was thinking about my step-grandpa. Then, we got the best idea: we invited him to join us. He fucked her on all fours as she licked and sucked my dick. Then, we switched and kept using all her holes however we wanted to. It was the best Grandparents' Day ever.
