one of two ways. first, right were everything starts off. the gang gets back to their safehouse and she's bent on repaying their dues. maybe they've trucked through the mud and muck, so she decides to forcibly clean him up and squeeze a booty call in that winds up being more drawn out after his refusals. i'm not thinking any penetration occurs here, but a bit of foreplay so she can see his stamina isn't entirely built up yet. or we can set things a little further down the timeline where she's more calculating and manipulative - finding ways and scenarios to toy with him.
