I can't remember a name of a yaoi with 2 neighbor's and a dil*o

So basically its a yaoi that's about 2 guys and they are neighbors. One of the guy buys a dil*o that can take shape of another person's shlong and the it like Bluetooth it to that guy??? So one day I belive they go to a bath house together and the dude with that bought the dil*o sees his neighbors shlong and is like I need that so he makes the dildo the neighbors shape but forgets to turn of the Bluetooth button on the dil*o. The neighbor feel everything that's happening to his shlong and doesn't know what is happening... and like that all that I can remember and I really want to read it again it was really good so if anyone could help a girl out I would be sooo grateful ╥﹏╥
