That night, Zashiki-Do appears in front of Junpei as he sleeps, changes Junpei’s body into that of a child, and creates an alter ego of himself from the days when they were close, and gives him a hand job and blowjob. The girl’s body and mind have become honest, and she returns Junpei to his original form and inserts his cock into her vagina in the cowgirl position. ……
