(not in that way you pervs)

Gon:
sleeping with gon was very comfortable. Except the fact that every night his hair kept poking you.

Killua:
you guys would fall asleep like you never slept for years and when you wake up you'll often question yourself on how you got to the bathroom while killua would sometimes end up on the roof.

kurapika:
he would cuddle with you to keep you warm but you being claustrophobic, punched him in the face still asleep.

Hisoka:
after sleeping beside him once, you never ever want to sleep with him again.

Illumi:
you basically made him your teddy bear with your suffocating hug.

Chrollo:
when ever you guys sleep, he made sure that none of the members would know

Feitan:
you would rest on his shoulder and made sure to go a little bit down because he's a 'little' short.
