Girl I recently gotten to know, fucked her a lot. Said she sucked dick once, when she was forced.

How do I "teach" her to blow me. Been approaching it slowly, finger in her mouth, trying to get her acknowledge me and my dick, not the person who assaulted her. Doesn't seem to help.

Considering taking control and getting her face close to my crotch but feels like a douche move, which could also backfire.
