I would have stuffed my dick back into my pants and left her. that can't be enjoyable for him having to listen to her laugh and complain while he is trying to fuck.
When your BF and GF you ain't just gonna walk out. And he might have been being an Asshole but lets not pretend this is her first time toying with that dick she should have been prepared
Useless!
He can fuck me and I promise not to laugh xxx
