[A4Fem] The Cum That Makes You Thicc

NSFWBodyTF

*After a terrible battle, a young knight is stuck in the healing church. They undergo an experimental procedure in order to save them from life threatening injuries.

This experimental procedure is the first of its kind. The knight heals rapidly, their body reknitting wounds and bringing them back to complete health. But the procedure has side effects. It causes the knight to be extra potent and virile, needing to orgasm multiple times a day to avoid further complications.

Any cum that is consumed by either the knight or anyone else causes a temporary spike in lust and bodily changes, these can be the growth of assets such as thighs, ass, hips, breasts, and lips. As well as the growing of a person's whole physique, additions muscle mass and height being what has been documented so far.

The knight is trapped in the healing church, unable to leave due to these miraculous effects.*

How does your character stumble onto this knight and what do they do when they realise what is happening to them?
