Seme/Uke with a Unique Condition

Seme and uke take turns becoming a meatball version of themselves. They still fuck.

Uke (yuuji) gets a curse inside his ass, and the seme (megumi) helps put medicine inside him and also uses this opportunity for them to actually have sex.

Not translated. But midoriya seems to have a quirk or some spell cast on him that causes him to have sex with UA boys. Includes gangbang scene at the end.
