Just repeatedly saying "relax" and/or "It's okay". As a big clumsy guy I have so much anxiety about getting carried away and hurting someone or making them uncomfortable. I like when she is the instigator. Also when she starts bargaining for sexual gain. I don't like it when porn narratives have a quid pro quo where the girl has to give up sex in order to get some help or whatever that shouldn't require a sexual barrier. But I do like it when that gender dynamic is reversed and she sexually motivated for her own gratification.
