Stars, Diamonds, Letters [Oneshot]

Title: Stars, Diamonds, Letters
Fandom: Hey! Say! JUMP
Pairing: Yamada/Chinen
Rating: NC-17
Wordcount: 4271
Warnings: Shameless pwp. Yamada's fake neck tattoos. Hickeys in questionable places.
Notes: I started this the day I went to the Dear concert, and then kind of didn't go on, but I'm a roll with wedding cake fics lately? I fully blame concert high and Yamada's stupid stupid neck tattoos for this fic. Also hi I wanted to compensate with a little otp since it's been a lot of other fics lately. (Wedding Cake Fic 6/8)

( The first time Yamada shows up with those tattoos is unfortunately at venue rehearsal where there are 45 other people around. )
