Since someone prompted Matt wanting to stick his dick in crazy, and who's crazier than Deadpool? (Well the Joker from Batman, but that'd be seriously weird on a riddiculous number of levels)
So, just Matt screwing DP up the ass. Maybe DP is less self-conscious about stripping off in front of a blind person? Maybe it's a threesome with Vanessa? Or Spidey (as long as he's legal)? Or a weird-ass dream?
