Tony stark was vigorously masturbating. Just the thought of the hulk got him off.
"Oh," he moaned. "A-a-a-aaaahhhh!" He came. Michael, his French lover, burst in, visibly upset.
"Are you masturbating to Steve again?"
Tony didn't even spare Michael a glance. "No, this time it's the hulk - I mean, can you imagine how big his penis would be?"
Michael scoffed and teared up at the thought of his ruined relationship with the other man in the room. He sobbed and ran out the door. "It's over, Tony! I don't love you anymore!"
"Whatever." Tony grasped his penis and rebooted his jack-off session.
