"Yes my pet... yes you will!"
The affects are immediate on poor Luna. Just like before her breasts swell up another cup size to heavy E cups. Her pussy gets wetter and her body fills out just a bit more making her look like a plus size model. Next a massive rush over takes her body, bringing her libido up to knew heights that she can tell will never go away, followed by a constant warmth between her thighs. Then... her nose itches and she is taken over by a sneezing fit! Three sneezes and she can feel her will to resist sex dissappear, more sneezes and she feels even hornier, even more sneezes and she feels a constant burn in her crotch that only Winston's cock can quench. Finally, with the last sneeze, she feels the last remains of her mind fade away, leaving only lust, submissiveness and a desire to fuck at all times.
Winston smiles down at her and brushes a finger over her lips, loving how she just naturally sucks on his finger. One by one he feeds her the purple potions, making her bustier, wetter, hornier, all just to make sure she is truly his. By the time he runs out she looks like a fertility goddess with wide child bearing hips, huge H cup breasts, thick cock sucking lips, an ass the jiggles with every step and a pussy that is always wet that constantly drools.
"You're beautiful my pet. Truly the most stunning creature I have every laid eyes on. Tell me pet. What is your favorite thing in the whole world?"
