It's hentai and I think a collection of oneshots, but not sure on that part. I can't remember who released it. I know that the was a hole in a fence and the boy for some reason decided to put his penis (are we allowed to spell it here?) through and then girl passed by and something something they had sex.

Any help appreciated.

Dude, try really hard to remember a little more, being that vague you'll never get a reply. I can recommend a hentai to you that is entertaining and will help you forget the other one (maybe, depends on how much of a perv you are 😎 ) It's called Take on Me

You're welcome

She says "yada!" but we all know she doesn't mean it.
