Pushed to the limit.....but finished the scene!

[Bud33]

Any body recommend a movie where the woman is clearly struggling.....yet makes it through the scene?

examples-
Veronica Rayne in Milfita 2
Milton Twin-Kylie Marie in Best Of Teen Anals
Daisy Dukes in Trained Teens 2
Teagan Presley in Just Turned 18
Jenni Lynn in Assault That Ass 3

These are some of my favorites. All were pushed to the edge...yet held on to get that all important money shot!

Anybody think of a similar scene?
Thanks
