Submission and dominance - Cassi had heard of such things, researched them on-line, but hadn't imagined she'd ever end up at a place specialised in teaching them! The penalty for her late admission is to be "adopted" by a dorm as a pet. She didn't realise that they had meant "pet" quite so literally! Having to crawl everywhere, with a tail shoved into her, is embarrassing, especially when naked except for her restraints. Eating and drinking from bowls on the floor, being taken out for walks, between other forms of submission training, start to have an effect, shaping her in both body and mind. And worst of all is the metal over her crotch, stopping her from having any fun - she's a good pet, doesn't she deserve to be bred? But all she can do is beg and whine, unable to even ask!
