(Yaoi) A Shrine of Male Relationships: Lost Anal Virgin in Threesome

"N-no…I'm going crazy!" My hakama is messed up, my skin is wet, and dizzyingly hot penis is thrusting deep inside of me…

Natsuki follows Kouta, who Natsuki loves, to a shrine in the mountain to help him clean. It isn't a normal shrine, but a shrine of relationships and fertility with offerings that are shaped like sexual organs. One day, Kouta's cousin, Yukinari, sees Natsuki masturbating with a dildo. "I'll make your body so that it will please Kouta," says Yukinari, and trains and develops Natsuki's body. "I can't...put such a thing in me...!" Natsuki's hakama is messed up, skin is wet, and finally, he'll do it in front of Kouta...!
