Sex Assassin 2: Pleasured Punishment

So after Sharday proved to all four of the men she was sexually involved with, that she stands by her name, the Sex Assassin. One of them started to catch feelings and he wanted her all to himself. But when they first met they had a understanding and Catching feelings was not the part of the agreement because they talked and she told him his role and she also told him the role of every other guy she was dealing with, and in the beginning he was ok with that. But after a couple awesomely amazing fucks he couldn't handle her doing that to anyone else and he wanted her to get rid of all of them and be with just him. So he told her he could cover all of her sexual bases, and she had no need to want another man. That sounded good but the only problem was that, each one of the men served a specific purpose sexually, and neither one of them could fill in for what the other one's job was because that's why they held that position because of how good they did their job. So she told him she would do exactly what he wanted her to do, and cut everyone off. But did she actually do what he asked her to do and cut everyone off for him? And who was it that caught feelings?
