Tyrion was admiring the streaks of green and red slicked over his cock. If it were a different woman, perhaps he would have been self aware of the situation and maybe take things slowly.
Unfortunately for her, it was the person he really wanted to kill most. Apart from Vladimir.
He was aware if how painful it as because he also felt as though his dick was been squeezed by a vice grip. He didn't care. Besides, she has done worse to him than this.
The thrusting started slow, not for lack of wanting to take it rough. Her body was still just so fucking tight. It fought him at every angle, though he knew time and patience would loosen her up. It certainly did, and Instructor Keisha's protestations grew less frequent.
Instructor Keisha was just trying to fucking breathe.
