You swallow, drawing your attention towards the lack of a particular lump in your throat, and force yourself to stand. Those are definitely breasts. They're not particularly large, but there's nothing else they can be. You look up at Vivienne and in a high, somewhat-hoarse voice, ask, "Why?"
"Oh, no particular reason," she replies with a shrug. "I wanted to see if it would work."
"Is this...reversible?" you ask, your voice smoothing a bit as you try to figure out how your throat works now. You continue prodding yourself as Vivienne asnwers.
"Oh, of course. I don't think any spell is irreversible. At least, none that I can cast. And in the realm of potion-making, the only thing that could make a spell permanent is a lack of ingredients. Erm, or death, but I don't deal in poisons."
Somehow, you find your clothes still fit you fine. Was that an effect of the potion? How would it--well, it did set you on fire, so you decide you'd best not question it. "Can I see myself?" you ask, curious.
Vivienne nods towards a mirror hanging on the wall, one that extends to full length. You're certain that hasn't been there the entire time, but it doesn't seem relevant, and you approach it.
The person staring back at you is very much a woman. Her hair is cut short, although it's definitely a bit longer and styled differently to the way you had it, and her figure is modest, not shown particularly well by her loose-fitting clothes. Her facial features are soft, much more so than yours, and her eyes are a sort of murky hazel to contrast your brown ones. And, if Hope's reflection is anything to go by, the woman in the mirror is about five inches shorter than you.
"Whoa," you say, turning to look over your shoulder. In the corner of your eye, you see the woman's reflection doing the same, but your attention is more on your rear, which is definitely more pronounced than before, although not nearly to the extent of Vivienne's.
"Whoa, indeed," says Vivienne. "Now, you have a few options for how you may want to proceed."
"I'm listening," you say, turning back towards Vivienne.
"That particular potion was for enhancing feminine traits, and it should wear off in a few days." Vivienne folds her hands behind her back. "In the meantime, I have some additional spells that should make your form more...palatable to the people around you - and a few different ways I could do that. Memory alteration, perception alteration, reception alteration, and the list goes on. Or, we could counter the effects to make you male again. And of course, there's still more potion there if you want it. You are a bit plain, if I may say so."
You think for a moment. You're very much not used to this body, but it doesn't feel bad, exactly. On the other hand, you're not terribly sure about Vivienne's other spells. Honestly, none of the options available sound terrible, but none of them sound great, either.
