grandmarian old woman with big ass riding her male friend

Grandma Marian was an old woman with a big, ripe ass that she used to tease her male friend. She would take him on rides on her back, seductively rubbing her ass against his body and causing him to become aroused. One night, she decided to take things a step further and propose something he never expected. She rode atop him, straddling his body and grinding her ass against his ever-hardening cock. She loved the way he desperately tried to keep his composure, even as his groaning grew louder. Each time her ass pressed against him, Grandma Marian could feel the fire growing in her core, intensifying with each movement. His hands roamed her body as her ass bounced against him in a frenzy. The experience was one neither of them would ever forget, and it reminded Grandma Marian that, despite her age, she was still very capable of arousing her male companion and making him feel alive.
