She’s been doing this since he was in diapers. That much is clear from the way she pins his wrists to the couch, her thighs squeezing tight around his waist like a vise. Thick thighs smack against his hips as she rides—wrinkled skin glistening with sweat, tits jiggling just enough to make it look effortless. He tries to flip her but she laughs, shoves him back down: Not yet, baby. Cowgirl turns into reverse cowgirl faster than you can say ‘grandma.’ By the time he finally gets on top? She’s already got one leg hooked behind him for leverage. Ass slaps loud enough to wake the neighbors.
