Bitch, for free rent+$300 a week in allowance you should be more demanding than that. There are men out there who'd do that for free or who'd pay YOU to do it. There are couples out there who give each other more oral than that for free without financial obligations. Unless you get off on having a live-in cunnilingus slave who you're paying this much I don't see why you'd pay that much. That's insane.
