1: Lots of blowjobs and sex in a hallway.
2: In a bathroom she gives lots of men a blowjob and has sex with them.
3: In a bedroom she has more sex and lots of them cum all over her ass.
4: During sex, men will cum all over her big boobs and then give her an extremely messy facial.
This one has scenes that are nearly identical to IPZ-320 (which was impressive IMO).
The movie sounds boring, but it’s very good actually!
