Seems like it could be a toxic relationship. The guy on the bottom has pushed the skinny guy away and refused to kiss, and it seems like skinny guy was retaliating by shoving his arm away, being aware of the camera and keeping his arm out of the shot --- and then stabbing him a few times with his dick while laughing at the bottom's pain. It's weird getting buttfucked on camera and then thinking a kiss might be too gay.
