younger fighter dominated by an older, out-of-shape opponent in a grappling match

It’s a heated, hard-fought struggle in bed; Scofild can't execute his jiu-jitsu moves against an older, heavier opponent. He faces a major disadvantage, finding himself trapped and immobilized—with no time to think—as he is suffocated by a rear-naked choke and his opponent's weight. The situation gets even hotter when he is taunted with slaps on the ass while being dominated in the grapple.
