Shit on someone?

You decide you might as well join in on the fun and get naked. You approach the nearest man, as attractive and horny as the rest of them. Fairly toned, nicely tanned and a moderate amount of body hair particularly on his chest. Leaning against a wall rubbing himself through his newly acquired diaper, seemingly soaked with piss. "You want my shit?" you ask, beginning to jerk off. His head perks up and turns to you, obviously excited by the thought. "Yes!" he whimpers as he gets on his knees. Submissive for a big fella. You turn and spread your beefy cheeks, he crawls to you drooling. "You gonna spread this on ya or just eat the lot?" you ask over your shoulder.
