Lum has been bound as a peace offering to the Xenomorph Slime King in hopes that her sexual servitude will be enough to buy peace between his planet and her own. The Slime King is notorious for having a desire to stretch tight innocent beings to their absolute messy limits, but Lumlum is up to the challenge. Lum understands that she will do whatever he needs to be satisfied. Once the Slime King emerges from his oozing goopy bucket, Lum rushes to his service, covering herself first in green slime, all over her hair and face. She makes sure that he enjoys seeing his alien slave all slimy and messy while she strokes and sucks him. Not wanting to displease her new master, Lum dumps the rest of the green slime over her head, and then continues servicing the King with her hands and mouth, sucking him and the slime as best she can to pay tribute. Hopelessly bound in her rope harness, Lum flops around in the tub, sliding about with her new owner, making sure he feels every bit of her body. Suddenly the lights go out, and LumChan is transported to a blacklight UV slime utopia where she can continue serving the King. Purple slime is the next task, and the peace offering does what is expected of her with it. The Slime King will wait no longer. He wants all of the way inside of Lum, and so on her knees, she lets him penetrate her previously tight pussy, where he just barely makes it inside. It takes a bit of struggling, but with some slime for lube and a few position changes, she manages to accept him inside. Finally Lum is in ecstasy as she gets the deep thick penetration she's been craving from the Slime King. In several positions she allows him to please her, getting lots of fabulous views as she uses her body and holes to save her planet. Certain that the Slime King needs her even messier, Lum dumps a bucket of slime over her face once more and we give you some picture-in-picture slow motion action as she does so. Laying on her back Lum tells the Slime King how she loves being stretched out by him and will always be his dirty little slime slut. Wanting deeper and harder you'd swear she's having a religious experience as Lum tackles the Slime King in several more positions and continues dumping slime on herself. Finally she holds the Slime King up and lets him drip his slimy goo into her mouth, as she thanks him, hoping her slutty ways were enough to save her planet. This scene is a vast departure from the normal ultra-cute nature of MessyHot. If you're not into depravity, role play, really big custom alien didos, and orgasms, this scene is not for you.
