Fairy Pairing

‘Park Gyu-chan’ lived a life of debauchery and one- night stands every day. Today again, Gyu-chan gets drunk as usual and wanders around clubs in search of his ideal partner. He finally meets a beautiful blonde woman with big breasts and spends the night with her. Gyu-chan wakes up in his bed, holding his head dizzy from his drunkenness. I witness the unbelievable sight of a winged man sticking something fierce into his anus. The man introduces himself as the fairy ‘Mon’ and asks Gyu-chan to save the fairy world… But… The way to save the fairy world is to cum in my anus?
