HELP

Hi guys, does someone know a manga about a boy who bought a adult toy and discovered that every time he touches it, his classmate can feel it? And he also has a half upper body adult toy that whoever he thinks about while using it, can feel the pleasure. He first tried it to his classmate, then next is to his neighbour. And there is points on how pleasured the woman is, the more his points go up, the more benefits or advantages he can have. Like, first he can only think about the girls he fantasise, then in the second upgrade he can see the actual face of the girl.
