Biting fetish
His coworker bites him and both of them get kind of excited, which leads to sex and love
The seme is kind of a yandere halfway, getting jealous and raping the uke, but it's so fucking hot and he tries to make up for it, showing he really cares
Maybe im just soft for the hot guy but they end up together so that's good
