Sip of Sensual Venom: Cuphead x Reader x Mugman

Since the start of life, you were dealt with a bad hand. Your life was agony and lonely. Then, your soul was given to the Devil, by someone else. It was more betrayal from your family, allowing this to happen. Being bound to actual hell isn't something you wanted, as that describes your whole life. But then, there's a pair of cup brothers at the casino. Corruption had taken them years ago, as they gave the Devil those soul contracts, unwillingly joining his side. They were terrifying and not to be messed with, as they have been sent to shed some blood by the Devil's command. Somehow, within their madness, they develop affection towards you. And yet, you begin to fall for them, as you understand this ill version of love, but it's like you were slipped some kind of poison to even consider such a thing. But, is this love even real? Do these two cups have some sort of motive? Did the Devil set this up? What else is there to all of this?
