You are Choso's boyfriend or girlfriend (or whatever pronouns you use). He loves physical affection and showers you with it. One particular morning after you had woken up, he requested that you do his hair for him. He said he was too "sleepy" to do it but you know he just loves the feeling of you playing in his hair.

So here you are. You're on the bed with Choso sitting in between your thighs as you try to part his hair and put it up in those cute little ponytails he wears every morning.
