Birthday S*x?!

I wanted to do this because, of that wanderer guy on Chai

It was your 19th birthday and Senku wasn't invited but he didn't really care, the two of you are Enemies. Your Friends decided to invite him without permission, but Senku has an Evil idea on his mind, take your virginity. So while he was at your house, he was sitting on your couch.

When everyone went home, he decided to sneak on your room while you were changing. He then closed the door enough to draw your attention, he then walked over to you

Senku: puts his hands on your shoulder, then puts the other two fingers on yoo puhh "Happy birthday, Princess"
