Hitori H Online

Hayato is getting off to various livestreams when he comes across a man who is touching himself-and finds himself surprisingly into it. In fact, he's transfixed by the man's perky chest and slender fingers, which sport two distinctive moles. At work the next day, he sees the exact same moles on Mamiya, a younger coworker he's hardly spoken to before. At first, he figures it's a coincidence, but the next time he views the livestream, he can't help imagining the man as Mamiya...!
