Expanding this into a full short fiction story :3 (Chapter 1 idk if there will be more)
You're not sure why she called you a good girl but, you don't dislike it, and then you drink the potion down. It tastes pretty good sweet, with a kick of spice, overall quite nice.
The Witch says she'll need you to come in each day for the next week so she can check for side effects. You ask if she can tell you what the potion does now. She says she's going to keep that a secret just a bit longer, but based on this 1st test she can already tell you're going to love it.
You wake up the next morning and you feel the best you've felt in YEARS, this is amazing! Could it be from the potion? Wait, there is one minor thing, your nipples are like, weirdly tender. It doesn't hurt, but when touching them they're super sensitive, and even pulling on a shirt you're still super aware of them.
When you arrive t her little hut outside of town you mention how good you're feeling to the Witch. She's delighted, and asks about any strange side effects you might be feeling. You get a little bashful but do mention the tenderness in your nipples. She asks to examine your chest, you oblige and when she ends up touching your nipples there's a jolt through your body, but not a jolt of pain...it felt, good? The Witch tells you everything seems to be perfectly fine with your chest for the moment, but to tell her if anything changes. You put your shirt back on and she says you're free to go for today. You head back to town and resume your day as normal, but the feeling of when she touched you lingers in your mind for most of the day.
This routine continues for almost the rest of the week, you feel wonderful, you go to the Witch in the morning, she examines you, and you're free to go back home, but something else is happening. Your nipples seem to be getting more and more sensitive everyday and each time when the Witch examines you she checks on their tenderness, and it feels so good, her gentle hands lightly touching the areola sends waves of pleasure through you. On day 6 you can't help but let out a moan.
Your face turns bright red, and you go to grab your shirt to throw it back on.
"Does it feel nice when your nipples are touched in their current tender state?"
You freeze at her words, your face is burning, but you have to respond.
"Very interesting, thank you for telling me. That brings us to the end of today's examination. You may go."
You put your shirt back on, far too flustered to form any kind of words, and leave the Witch's hut. The next day you have to wrestle with yourself to get to the Witch's hut, you feel so embarrassed about the day before. It takes you much longer to gather up the courage to go there, and so you arrive nearly a full hour later than you typically would. Upon entering the Witch says
"Oh good, you're here, I was afraid you weren't coming for a moment"
"I-I'm here, um sorry about yesterday"
"Oh, sweetheart, why are you apologizing? You did nothing wrong. In fact I have a bit of a question for you."
Almost bewildered by her comforting you, you respond
"So when I'm examining you today and I check on your tenderness, would you like me to keep touching you?"
"Would you like me to keep touching your super sensitive nipples beyond the basic check in today? It clearly feels nice when I do it. Would you like me to do it more?"
"I-um-wel-uuuh-you-um" your face is on fire, you must be dreaming or maybe she's pulling a prank on you or or or-your anxious spiral is cut by her words.
"Ah, you're still clearly quite flustered from yesterday. How about this: you don't need to say it out loud if that's difficult at this juncture, simply nod for yes or shake for no. And know that I am fine with either answer."
You take a very deep breath to calm your nerves and nod once.
"Very good, you may lay down on the examination bed now."
Her examination feels very routine for the most part until it comes time to take off your shirt, you take another deep breath and slowly remove your it. She medical like analysis continues until she reaches your nipples. First the delicate and familiar touch of her examination happens, it feels so nice that another moan almost escapes your lips again, then she keeps touching them, wave after wave of pleasure begins to rock your body as she's massaging your chest.
You feel tightness growing in your pants, you're getting hard from her just touching your nipples. At this rate she's goning to notice you're rock hard at any moment. And just so, she glances down towards your tent.
"You may remove those if it would be more comfortable, however, once it's out no touching anything down there"
Before you fully process what was said your hands are already pulling garments away, but you control yourself enough to not touch. You'll be good for her, but you want to so bad, you're so hard and her touch feels so good. You feel like you're melting.
Suddenly she stops, you can't control the whimper that escapes your lips, her head lowers down to just above your chest and she blows across your nipples. It's too much, they're too sensitive, you're going to explode, you're going to-she starts stroking your hair, and massaging your nipples again and you lose all control.
You cum the hardest you have in you don't know how long. You're not sure any orgasm in your life even holds a candle to this one, and she did it just by touching your chest. The ecstasy washes over your body as you lay there breathing heavily, as she continues to gently stroke your hair, and after a moment you realize she's sweetly whispering to you.
"You did such a good job, you're such a good girl for me"
You don't know why, but you've never been more happy than hearing her say that to you. You lay there on the examination bed, slowly breathing in and out, as she soothes you for a bit longer. Eventually you come back down, she helps you get cleaned up, and dressed as you get ready to leave for the day. As you get ready to go you hesitate for a moment, wanting to ask her something but you can't think of what. Her voice, once more, brings you back to reality.
"Would you like to continue the experiment tomorrow? It would require drinking another potion."
"If the second is anything like the first, I would love to."
"Good girl." She says with a sweet smile.
For the first time, you begin realize that you do understand why you like her calling you a good girl so much, but you have things to get done today so you'll have to save really thinking about that until tomorrow.
