Why are sorceresses always so, well... well-endowed? As well as the rhetorical opening to a thousand dirty jokes, it's also a subject of serious magical research. For years it was thought that channelling raw mana had a stimulating effect on the hormonal system, but recent studies have lead arcanists to believe that it's just the reverse. Sorcery doesn't make its practitioners more curvaceous: rather the particular combination of glands, body fat and nerve endings some women possess in such abundance is uniquely suited to the storage of raw mana. Flat-chested women, in other words, just don't pack enough punch.

Which is where our heroine comes in. She was channeling in the crib, and by early childhood displayed control and intuition rarely seen in even the most seasoned spellcasters. When she finally had the mana reserves to start doing real magic, she would be a force to be reckoned with: a sorceress possessed of power that had not been seen in generations. Then came puberty, and...

...passed her by.

Such is fate. Even our flat-chested heroine's cantrips were enough to make a career in sorcery seem possible, but now at the age of 25 she's all but given up on ever realising her true, staggering potential. Just another hedge mage, who could have been a contender...

...which is where our 'hero' comes in.

Hi, and thanks for reading this far! In this prompt I'm looking to either play or GM for the hapless 'hero' of our tale, who - by magical accident, a curious turn of fate, or malice aforethought - becomes the heroine's walking, talking, bouncing mana battery.

All forms of MtF transformation - partial, ongoing, instant, slowburn, reversible or Tiefling - are on the table here. Please suggest what sort of thing you're looking for in your opening message, as well as which role you're interested in playing.

Other relevant kinds here include humiliation, non-con/dub-con, D/s, mind control and bimbofication, outfit play, and further bodily modification. Limits are the usual gore, vore, filth, and underage.

Hoping to hear from you soon!
