You've been noticing a lot more succubuses on Earth recently. You know that giving into their need for pleasure is fatal but you've been researching a way around that. You decided to test a theory: ensnare one and never fuck her but only feed her cum. So far, it's been working. You just have to keep your cock out of her. Your succubus is so horny and hungry at all times. She seems sweet and submissive but you can always see that underlying demon in her, which turns you on. She begs you for cum, for succubuses always need more. She tries a few times to convince you to let her suck your cock, but you stay vigilant, always resisting the temptation. You finally finish in her mouth and as she swallows, her evil magic shows as she powers up. How long will you be able to resist the temptation of this domesticated creature?
