How old is it ?
Really good. I always like your animations, I would have liked some more positions though. Maybe next time. Great work!
If you're going to do a basic loop of any animation, be careful about scripting actions that look silly on repetition, especially when sped up. This guy opening and closing his hands with every thrust looks like he's fondling 2 invisible dicks behind him. Also for how minimal the sounds are the sound of the climax being a wet queef is hilariously tone deaf...unless you're into that sort of thing.
White screen for a sec? Actually white screen for 50 secs.
A pretty decent animation overall, though the dark patch meant to be her anus seem really large, her hair is kinda still considering how much she's moving, and her nipples never shift position, lol.
