Benjamin Blue, the horny stepdad, offers his stepson Jeremy Spark an unusual kind of workout support. As Jeremy pounds away on the treadmill, Benjamin can't resist the temptation of his tight ass. He moves in, spreading Jeremy's cheeks to reveal his pink pucker, then dives in for a deep rim job, lapping at the sweaty hole. Jeremy, now rock hard, turns to face his stepdad, and they engage in a passionate 69, sucking each other's big dicks. Benjamin then mounts Jeremy in doggystyle, his massive cock stretching Jeremy's ass as he pounds away. They switch positions, with Jeremy now riding Benjamin's cock, taking it deep while they make out, tongues entwined. The workout ends with Benjamin breeding Jeremy, filling his mouth with hot cum.
