If she also got fucked in the vid, then $800 would be the rate. $800 seems to be the price floor for b/g no matter if the bj at beginning of scene is the regular kind or through a glory hole or through a box of oranges. Swallow never pays extra either. If she got $700, it's probably from a smaller company that told her (a girl who doesn't work much or rent was due) "that's what we offer; times are tough."

Regardless, sounds like an alright deal for both parties.
