It's quite an old looking hentai. So this girl has super powers and she is about to transform, but a guy stops her and rips her clothes off. The guy (who is wearing a gas mask or some sort of mask) then fucks her and puts his finger in her ass. I think he shags her over a table. It's also not censored like a lot of hentai are.
I don't have a picture or anything so any help would be greatly appreciated!
