I've been trying to find a doujin I've read 10 years ago. I'm pretty sure it's korean but there are some cliché tropes that might make it hard to find.

Pic not related.

I remember there are at least 2 chapters.
The story is set on a school, the MC is a bully and he bullies this thicc blond femboy.
After stealing his money, he spits on him and the femboy opens his mouth and asks the MC to spit there instead. After that the MC goes to his home and begins masturbating to straight porn to clear out that picture from his head. After realizing he wont't be able deal with his gay ass bonner, he takes the femboy to the rooftop and begin to make out with him. I'm not sure if the femboy had female underwear but he had a plug or anal beads inside of him already. They start to fuck and the femboy makes this ahegao when he gets the D inside of him.

I think they start to date or something like that and the femboy has a sister or brother that crossdresses but I'm not sure.
