Unbeknownst to him, a hidden camera captures this lucky guy's secret pleasure. He thinks he's alone, but his girlfriend has other plans. As he strokes his throbbing cock, lost in fantasy, her soft footsteps approach. He's caught red-handed, his rock-hard dick standing at attention. Her surprise turns to anger, then lust, as she decides to join in, straddling him and riding him hard, his earlier solo session now a shared, passionate encounter.
