No no no come back. I love the way you think.
Also consider Megumi saying "daddy" hnnnnnnn I need it so bad you have no idea
Megumi chanting a combination of "dad" and "daddy" as he fucks Sukuna, too wrapped up in the moment to realise what he's saying until after the fact when Sukuna teases him. "Daddy?"
You know he's gonna rile Megumi up going forward, asking him "who's your daddy?' and "moan for daddy," or "how can daddy make you feel good?"
