When Marc walked into his gym's locker room after a workout, it was completely empty... with no one around, his mind (and hands) wandered towards what he'd be getting up to back home~
Only, he got quite a bit too involved in his own fantasies and didn't hear another gym-goer enter the showers next to him... and it didn't take long for his activities to be noticed~
He's a bit too occupied to care, though.
