This is about a big titted girl, a coin laundry, two guys and rain. Mix everything in and you’ll have the girl being fucked because, well, it’s hentai. The girl would be fucked regardless of the setting just because she’s a girl with big boobs. Actually, the fact that she’s something that can feel pleasure is enough to get fucked in the hentai world. Which is obviously just like how our own world works.
Anyway, it’s a nice one with nice art. And it’s fully colored so we get to see some weirdly pink crotch.
