Bound to a Serpent

Official English on Renta

A giant serpent appears in front of Yura. It wraps itself around Yura and doesn't let go, telling him that he's been looking for Yura for a long time.
Yura is a teenager who doesn't remember much about his childhood. After he gets a phone call about his grandfather being hospitalized, he starts remembering the place where he grew up. The voices and images make him pass out. He wakes to find himself in a cave with a giant serpent... The serpent is ecstatic to be with Yura and tells him that it's been so long he's seen Yura. The serpent tells Yura he wants to enjoy their reunion as much as he can. He kisses Yura with his long serpent tongue and brings him pleasure with his smooth scales.
