Luna, a mentally unstable subordinate who likes her boss, happens to overhear a conversation during a break about how good his wife is at giving blowjobs. But I can do it better! Jealous and mad, she whispers, "Blowjobs aren't cheating, you know?" and seduces him, and cuckolds him with a blowjob. "Your wife can't suck like this," she says, making him cum multiple times with her vulgar technique of taking his balls deep in her throat and licking them, and even though they're covered in sperm, she keeps cleaning them up until they're empty. I'll make sure he can't live without me anymore.
