Katrina Colt, the gym's naughty MILF coach, can't resist the temptation of a client's rock-hard cock. She strips off her sports bra, her small tits bouncing free, and pushes her big ass out, inviting his thrusts. She takes him deep, her big booty slapping against his abs as she rides him rough. The gym's mirrors reflect their taboo dance, Katrina's full lips glistening with spit and cum as she switches between sucking him off and taking him hard from behind, their workout turning into a hardcore fucking marathon.
