My "Toy" is Connected to My Best Friend

Jin, heir to his family's shrine, has a secret. For years, he has harbored a crush on his childhood friend, Misaki. Misaki, who Jin sees as pure and innocent, looks up to Jin with reverence and awe for his dignified and almost otherworldly appearance and grace in his role as the son of a shaman. Lately, Jin's crush has been becoming more and more sexual in nature, and he can't seem to keep himself from gazing longingly at Misaki and fantasizing about him. Fearing that the truth of his feelings might ruin their relationship and taint Misaki's perception of him, Jin refuses to give even a hint of his true feelings, and as a result has become more and more pent up from suppressing his desires. This buildup of sexual frustration has led his dreaming mind to wander, and every night Jin is overcome by fantasies of himself and Misaki entangling their bodies together in sin-filled lu**. At the end of his rope, Jin leans on a senior classmate from a spiritualist club for assistance to help him find a way to let out his pent up energy. This club member lends him a new s** toy from his collection, advising him only to use the "miraculous" fleshlight if nothing else will work. It isn't long before Jin feels no option but to turn to the adult toy, and after a full night of indulgence, Jin comes to rely on the strange s** toy at all hours, both day and night. Over and over, Jin releases his lu** for Misaki with the adult toy, but as it turns out, this is no ordinary fleshlight. Its warm and sticky narrow passage squeezes and spasms around his fingers as he inserts them, movements that make the toy feel as if it were real. Well, unbeknownst to Jin, by some miracle or curse, the opening of the fleshlight is directly connected to Misaki's a**! As it turns out, every time Jin relentlessly ravages the toy, lost in fantasies of himself pounding desperately into Misaki, Misaki finds that he is himself being sexually tormented by what he can only imagine is some sort of perverted ghost. What will happen as a result of this "miracle" toy? Will this strange s** toy somehow bring the two of them together, or will the inevitable realization of the truth shatter their relationship completely?+
