Is This Love

Starters

(This is just some info about frisk falling in the underground and meeting chara)

Frisk fell in the under ground and was found by flowey,who immediately brought him to Sans.
Sans gladly took frisk into his home and told Papyrus not to tell Undyne or anyone else,he was hesitant but agreed and made frisk his best friend.
Sans told frisk not to go anywhere past hot land, because the Dreamurrs hated humanity (because Chara had convinced them),but chara had changed his mind about humanity and decided to give them a second chance.

One day frisk went into hot land and was caught by chara, but he didn't do anything but introduced himself. frisk was scared but soon introduced himself right after.

Later on the two boys became friends and hung out almost all the time, but as soon as they became teenagers things started to change(and no, I'm not talking about physical change)
They started to see each other in a different way, a lustful way.
Chara would masturbate, thinking about frisk, and frisk would do the same but think about chara.Sans on the other hand has some fun too, chara wasn't the only one thinking about frisk.

I'll write the first chapter tomorrow.... See ya!
