Looking for twiseted Yaoi

I don't know if it will be on here, since I read it on myreadingmanga. It's about a seme who only sleeps with virgins to take their virginity and dump them. But he ends up, frequently sleeping with his coworker at work. When he tries to leave him cause hes not a virigin anymore, his coworker basically makes him incapable of getting hard for anyone else, or something like that. But basically the uke did an uno reverse, and the story ends with the guy always having to have sex with the uke. And theres a scene where he puts tape on his ass to keep the cum inside him, but it leaks during a presentation.
