As you got into Sans's room... He was naked... His naked skelton really shows... no clothing, no boxers... but you can't help but LOVE him... as you came to him and pin him down mattress as you grab his vertebrae... his phalanges grabs your hand that was holding his vertebrae as he blushes red and he also feels... thirsty... as the drool? was coming from his mouth and nose(skeletal nose)...
