“Nice job jerking off my big cock, but now I have cum on my stomach.  I think you should lick that up.”  

“I don’t want to taste your cum, I am not a fag.  I thought we were just guys helping each other out? You said you would jerk me off next.”

“I lied, to give you an excuse to touch my cock. You are obviously a cum hungry fag, and wanted to touch me.  Look at you….my cum is splashed on your face, and you have made no move to wipe it off.  You are still holding my meat and slowly stroking it. You are a fag. Now get down there and clean me up.  Do a good job and next time I’ll let you suck me dry instead of stroking it.”
