Ok but like

Eren and you at his very first R&B concert and Eren been warned that there may be erotic shit happening on stage. He didn't care cause at least the songs might be good. Yet when the erotic dances and scenes happen, he couldn't help but imagine you doing all those things to him.

Stripping in front of him, giving him lap dances, grinding against his crouch in front of everyone, just the most down bad things ever but it's too embarrassed to say that.
