Tanner Mayes

I love Tanner Mayes and i've followed pretty much everything she's done since she started in the adult business. But recently i've been worried about her.. I've seen a few scenes with her this year, the one from Her Freshman Year was awesome, i love that innocent and gentle cocksucking she does, just like old times.
But then there's these anal scenes she has started doing, and she doesn't seem herself.. first of all, in both Nasty Anal Tryouts and the new anal scene from Bang Bros, she has these weird tics and twitches in her face that i've never seen before, and they only appear in these two videos. Do anyone have any idea what is the cause of this? Has she taken some kind of muscle relaxers before the scene or other drugs or something like that? I almost feel guilty watching these scenes because.. i dunno, she's not herself, all these nervous twitches and stuff, i want her to feel good about the scenes she appears in.
I'm not trying to be mean, i just wanna make sure she's alright and that she enjoys these scenes. So an explaination would be great if someone has any idea.
