To be honest, when you put it like that...
...it does sound incredibly hot!
Knowing you brought someone crazy, to the point of cumming. Knowing you, your body, drove someone to such a desperate point, that they had to moan, they had to let you, anyone know, that it feels oh so good.
That they have to cum.
Now I got some inspiration again!
As for what an erp is, Erotic Roleplay!
EDIT: Also, judging by your username, I might as well offer to do the same for you, if you find it hot. Or something similar if you have a request?
Ngl, not feeling hornish, but if I can, why not?
