Reversal Potion, but it doesn't work

It had been a fun trial run, and the idea of goblin children popping out of his womb was more than appreciative, but this agonizingly painful lust was something that he wasn't particularly wanting at the moment. Especially when each orgasm just brought him to his knees no matter how good it felt, and he wanted more than just his fingers. Sometimes, perfection isn't just good enough. Finding his willpower, he found himself walking while still rubbing his clit, his juice-stained hand finding potion bottles and quickly making something... Quickly. The urge was rising again and he made the reversal potion, downing it in one go.

He stared at his chest, those bountiful breasts were going to be missed.

Surprisingly, they only responded by the light bounce as he fingered himself. It wasn't going away.

To his horror, he realized that the potion wasn't working. Why? As another bout of lust sought him, Kazex found himself falling to the floor as he grabbed a particularly hard and long flask and slammed into himself, moaning, not knowing how much time had passed.
