Well, right now I can only think of one scene at the front of my mind, but unfortunately I'm not sure on the name of the movie... I talked about it in
this thread (if my link doesn't work, scroll down to the fifth post from the top). It features cute American girl Tiffany Holiday. She gets a really hot anal pumping in multiple positions, ending in an anal piledriver, after which her fucker pulls out his cock and jerks off onto her gaping asshole. Her anal sphincter's rhythmic contractions cause his cumload to get sucked into her ass

Then he penetrates her ass again while she's still gaping and fucks her a little bit more, now that her ass is freshly lubed up with his semen. After he's had enough, Tiffany fingers her butt and squeezes out his load, letting it drip out onto her pussy lips, then tastes it with her mouth.
Here are the pics I posted in that thread:
