What kind of agreement?

You are about to respond with a resounding 'HELL YES' before you mentally slap yourself out of haze of lust clouding your mind and ask a question of you own. "What kind of partnership?" Your mother may have been a bitch, but she made sure not raise any stupid children who would get fucked into submissive sluts the first chance they got and made sure you knew how to resist your submissive instincts enough to make clear choices. You hear the hag behind you respond, "You're smarter than you look," she giggles, "good, I prefer my partners to be more equal".

You feel her move away from you so you take the opportunity to sit up and get a good look at your potenial "partner". She certainly looks like a water hag, with blue skin and seaweed hair styled in a pixie cut. She's at least 8 feet tall, her breasts are G cups and her ass was about twice as big as yours. You're eyes are drawn to her cock, a 20 inch long 6 inch thick piece of meat, and it takes all your willpower not to bend over and beg her to fuck you.

Your focus on her body is broken as she continues speaking. "I'm proposing a mutually beneficial arrangement for the both of us, a 'you fuck my ass, I fuck yours' kind of deal." This is already starting to sound good. "I've spent years studying magic in this swamp, but recently my progress has slowed to a crawl. That's where you come in. Your kind has the potential to master any kind of magic, something I'd very much like to do myself. I'll teach you magic and help you gain those tails your kind is so famous for, and in exchange you'll let me study you as you progress".

You still feel a bit skeptical at the offer. You're just about tovoice your thoughts when the hag continues talking. "How about I sweeten the deal. I have several servants who are away on various errands and your status as my partner will allow you to use them as you see fit". Your cock tingled at that, a having group of monsters at you beck and call is every kitsune's goal. Sure they won't technically be yours (yet), but its a start. Still the lessons your mother drilled into you make you hesistant to accept.
