Very poorly directed, this scene makes no sense, and so my brief summary has to rely a bit on my imagination.
Katie Kush is at college and sexy Christie Stevens, is with her, presumably playing the dorm mother (judging by the subsequent action). Van Wylde arrives as a new overage student (in his 30s) who both ladies welcome (individually) him to his new room with exuberant sex.
Van plays the vignette bewildered, just as I was watching it. Eventually they have a threesome, but the tipoff regarding how Brazzers currently considers its content is when early on, Kush is giving him a hand-job as he lies on his back on the bed -cut to a fake cumshot hitting the ceiling. Yes, fans, Brazzers sex is played for slapstick laughs lately.
This amounts to a big waste of time for Christie, who is a fine actress and deserves better roles than this truly silly stuff.
