Jongin goes to a tattoo parlor to get a piercing in a very intimate area. Upon arriving at the establishment, he gets anxious, wanting to chicken out and go home, but the piercer has a few tricks up his sleeve to calm him down. 

Four months later, Jongin returns with yet another area he wants to be poked, but his piercer wants to see how well he's been taking care of his last one.
