"Didn't I say that was what I was trying for?"
"I know you did. But I didn't think it would actually work!" She looked up in wonder.
"Hnn~!...H-How did you do it?" She asked as she fought the urge to moan.
"I honestly didn't do anything. I'm just stimulating you in such a way that you'd naturally want to and will spread your legs in front of me." I said, which she didn't seem to understand as she tilted her head and looked at me weirdly.
"Look at the way I'm holding both your hands above your head and not letting you stabilise yourself. This is so I can create an imbalance in your body and only allow you to balance and keep yourself from falling down using your legs." I started to explain so she could understand.
"If you only have your legs to keep yourself from falling down, then the only way to stabilize yourself is to spread and close them to maintain your balance, which is exactly what I want you to do. And to prevent you from trying to close your legs, I'm leaning you a little back as I hold your hands from above, which stops you from closing your legs. Since that would only make you fall on your back even faster if I let go of your hands, which your body's reflexes won't allow."
"I understand that part. But-...Hmm~!...B-But I still don't understand how my legs are s-spreading, even though I don't need them to spread so much when I'm balancing myself." Astrid was quick on the take and even asked a question in return, even when she was starting to shiver from the coldness of her underwear, which was really starting to get drenched.
Even the socks that were in contact with her underwear started to feel wetter than before and even felt a little sticky, as if I had stepped into a puddle full of viscous fluid.
"You spreading your legs has nothing to do with balance." I told and then looked down at her underwear, which had darkened in colour, and said
"You're spreading your legs on your own in reaction to the stimulation you're feeling down there"
"Hnnn~...R-Really? How does that work?" She asked in a very scholarly manner that fit her lab coat that was pushed to the back, allowing me to see her long legs as she fought her urges.
"Well, it comes from the commonly known principle when it comes to warm-blooded creatures that a female who is about to indulge in coitus will 'make way' for the male when she comes in contact with something that will trigger her sexual desire to mate." I said in a professional manner, which I thought Astrid would like.
And just in case she didn't seem to fully understand since I was comparing her to a rogue animal, I said
"In simple terms, it's because girls normally spread their legs when the guy pleasures them underneath, so that they could give them some area to work with so that they can make them feel even better."
This explanation of mine stopped Astrid from deeply thinking about my previous explanation, as if she were thinking about the logic behind it like an actual researcher, and made her blush like an innocent girl. Her tail also swept the floor vigorously, as if it could feel its owner's embarrassment and was sharing it with her.
"Of course, some shy and inexperienced girls like you tend to close their legs in response to some pleasure underneath."
"And that's exactly why I held your hands up and tilted you in such a way that your body would reject the feeling of closing your legs and would continue to spread them."
"And speaking of spreading them, it looks like you've spread your legs enough." I said as I looked at her legs, which were spread so apart compared to before, that I could clearly see the outline of her hidden place as her underwear streched apart along with her legs, which made them press onto the flesh underneath and reveal its outline.
Her head was also right next to my zipper, after she spread her legs wide enough so that her butt was much closer to the floor and where her height would not be an issue for the extraction.
Astrid also noticed her underwear's moist state and how dark it was from being drenched in her fluids that she released. She couldn't help but blush profusely and shook her head as if she were blaming herself for being such a shameless girl who got off someone's feet.
But she also seemed to be in wonder at how her legs spread on their own without her even feeling them move. She even touched her inner thighs to check if it was really her legs that were spread that much, when she knew her own physical capabilities and thought she could never keep her body in such a difficult position.
"I can't believe they really spread wide on their own, just like you said they would. And that without even touching my legs or making me feel any sort of pain."
"I thought for sure you were going to force them apart like you were pulling apart a stalk of bamboo." She said while looking at me in awe, to which I gave her a proud look as if I was telling her to never doubt my skills.
I may find it difficult to solve every major problem in this world. But when it came to satisfying a woman, no one would dare say they were first when I put myself in second place.
"But where did you learn to do that?" Astrid asked.
"Did you read it in some specialised book about 'those' types of activities? Or did you learn it through experience from your past partners?" Astrid asked, narrowing her eyes as she looked at me.
"I learned it at a place called the 'Garden'." I told her truthfully, knowing that she wouldn't understand even if I told her the name of the place.
"Garden? What kind of place is that?" She furrowed her eyes in curiosity and asked about the weird place that seemed to teach weird things.
"A place that doesn't exist anymore..." I said ruefully, thinking about the time I spent in that horrendous place and the joy I felt when I sent that facility and everyone that ran it on fire and watched it all burn with the first genuine smile I've had in years.
Astrid still seemed to have doubts about the peculiar place I mentioned. But I didn't really want to dwell on it too much, so I interrupted her and said
"Now that you're at the appropriate height, you can take off my pants like you wished."
"But make sure to take it off gently, as I don't want to go back home half naked and in my undies." I joked.
"Of course! Although I can't take off another person's clothes as quickly as you, I can still take them off without tearing them off like you said!" She harumphed and pulled my white shirt up to remove my belt, forgetting about what she was going to ask about the Garden.
"But Astrid..." I suddenly held her hands that held the belt she had taken off and looked at her with a sincere expression on my face, as if I were pleading for her to listen to what I say.
This action of mine surprised her and made her gulp, wondering what important issue I was going to raise, which made me act so honest and sincere in front of her.
"W-What?" She asked nervously, to which I responded with a solemn look on my face.
"Just promise me that no matter what you see under my pants, you won't run away in fright or faint on the spot, and you'll calmly assess the situation without freaking out."
"Please promise me that one thing before you take my pants down, and I will be forever grateful to you, and we can avoid many unnecessary problems that may come along with it..." I asked for her promise and sincerely held her hands in hopes of her doing as I said.
