People have different ways of dealing with "danger" (if you can call this situation danger). Some people would surely fight back, but others are like deers caught in headlights and freeze not knowing what to do next.

Oral yes, but without a strapon she "can't" retrieve a blowjob. But in this plot the possibility is not the main aspect. She does not go home and then think "Wait a minute! I don't have a dick! He can't give me a blowjob
" "Ohh I know, I just ask him to go down on my boyfriend instead
It's more of a game the two of them play. Think of it this way, bi curious guy has a hot girlfriend who happens to like to tease, and they want to bring other people into their life. Not that uncommon for couples to invite other people into their bedroom. And in this case the two of them happen to be a little... mean.
