One day, two girls from the top of the class hierarchy come to play at a dull otaku boy's house. It's getting late and just when you think they're going home, they suddenly start taking off their clothes! ''You...two girls coming to a guy's house...did you really think there'd be nothing going on?'' The otaku boy is forced to have a threesome with the two girls without even knowing what's going on. After being drained to the point of exhaustion, he wakes up in the morning to find the girls sleeping comfortably next to him. However, when he looks more closely, he notices that they have cat ears and tails...!? ------------------------- Such a lucky guy...
