Undercover, the private eye infiltrates the unsuspecting couple's outdoor rendezvous. The blonde, eager mistress, unaware of her husband's surveillance, sucks the detective's cock with wild abandon. He returns the favor, tasting her wet pussy before sliding his shaft in, fucking her doggystyle in the open. She then hops on, riding him cowgirl-style, her natural tits bouncing. As they change positions, the detective's thick load spills onto her chest, and she milks his cock for every last drop.
