Kegel Spanking
Rene struggled desperately, but a woman who couldn't use magic couldn't beat a man. "Eek!" I skillfully bound her delicate wrists with the slime rope. "Today, before the Kegel exercises, we'll check your sensitivity." Specifically, I was going to measure exactly how long it took Rene to reach orgasm once. The faster she came, the more sensitive she was, which meant she could feel satisfaction even from a man with weak stamina. My goal was around three minutes to reach climax once. Of course, it was difficult for her as a woman to reach orgasm within three minutes, so I had to check her sensitivity for a long time.
"Ugh... you filthy bastard..."
"Now, let's see how long it takes until Rene reaches orgasm." I took a pocket watch out of my pocket and placed it on the living room table, then brought the vibrator into the living room. Setting the chronograph by pressing the crown, I spoke to her as she glared at me. "I'm going to send Rene off with the vibrator. All you have to do is try to feel it as quickly as possible."
"Pervert!"
"Calling me a pervert? Yesterday you were begging me to fuck you, remember?"
"Th-that was..." At my words, Rene's face flushed deeply. "Aah..." She seemed unable to continue, probably recalling last night's events. "From now on, training begins, so watch your words—unless you don't want to cum even once today."
"Shut up!" Watching Rene speak harshly, I thought I should make a reward and punishment chart later. "Since you said something bad to me, I'll deduct one point."
"Haa... you perverted bastard!" To her fiercely glaring eyes, I spoke strongly. "Do you want to be hit? I can whip you nicely with a crop."
Now she was a bit quieter. I put on my glasses and brought the lubricant. "Let's make it feel good today." This lubricant had good moisturizing effects, a pleasant scent, and was good for quick stimulation on a dry vulva. It was like this world's version of love gel. I gently pulled down Rene's panties. Fortunately, she didn't resist my touch. It seemed she'd learned that resisting only made things harder for herself.
Her cute pussy buried in gray pubic hair. I applied the lubricant evenly to her pussy.
"C-cold!"
"Bear with it. Applying this will make it not hurt and feel good."
"There's no way it'll feel good." Ignoring Rene's sulky expression, I finished setting up. With this, preparations were complete. I would accurately measure the time for Rene to reach orgasm exactly three times. And use that as a baseline to try to make her come even faster.
-Vrrrr~ As I stimulated her pussy with the vibrator, I pressed the crown of the pocket watch at the same time.
-Click. Along with the slowly moving second hand.
"Hng... haa..." Rene panted. "Haa..." My hand movements were simply aimed at sending her to climax without any technique. "Hwaa..." Watching her close her eyes trying to reach orgasm, I checked the watch. About 8 minutes passed? Excitement level: 68%
"Hng!... haak!" What? She was trying really hard. I was rather surprised to see Rene feeling it so intensely, beyond expectations. How did it jump 23% at once? It was hard to believe this was the reaction of a woman who said she didn't feel good. She's incredibly lewd. Well, since I made her that way. Not bad. But I couldn't just let this amusing situation pass, so I teased Rene.
"Excuse me... but your words and actions don't match, do they?" Then she looked at me with an expression saying she didn't know. "Haa... what?" Embarrassed, she didn't show her face directly. Sly... incredibly sly. Seeing Rene who seemed to have reached a level of enjoying the training, I slightly lifted the vibrator and stopped the stimulation.
"Haa... what..." Rene looked at me with a reproachful gaze as if asking why I stopped.
"You were concentrating so well... do you want to come that badly?" As I looked at her with narrowed eyes, she buried her face in the sofa and spoke softly. "...Do you want to be tormented too, feeling like you're about to come but can't?" Her actions were shy, but her tone was rather bold. So, wanting to see her cute appearance, I deliberately scolded her a bit more.
"Normal people don't feel anything. It seems Rene is just an incredible pervert."
"Hng... ah... no, I'm not?" Though she said that, what was certain was that Rene's resistance had weakened a lot. Even if she hated this act at first, having experienced the pleasure as a female, she probably wouldn't feel much aversion now. So, this is where it begins.
Rene, who had tasted the joy of orgasm. She was still far from being lewd. If I had to compare her lewdness, she was lewder than a virgin, but weaker than a nymphomaniac—more like a married woman?
There was a brief silence.
"Ugh...!" Her waist slightly lifted, thighs trembling. Checking the status, it reached 70%, and she reached a light orgasm. "Haa... haa... too... strong!" Was it because it was mechanical? Her excitement dropped from 70% to 0. I glanced at the watch; it was a little past 10 minutes.
"First orgasm in 10 minutes... looks a bit pathetic." Rene slightly turned her body and looked at me with resentful eyes.
"Doing this every day... how can I last long?"
"For your information, a pathetic pussy is something you're born with." If you weren't born with a pathetic pussy, training would be much harder. On the other hand, Rene's pathetic pussy made the sensitivity training very effective.
After mechanically sending her to orgasm about two more times, I checked the final time.
"35 minutes..."
"Haa... haa..." Rene's pussy, mixed with lubricant and love juices, reflected light glossily.
"From now on, we'll do this sensitivity check once a week." The dazed Rene had no reaction other than breathing heavily. Well, three consecutive times must be tough. Since I sent her to climax consecutively without any rest time.
"Come on, snap out of it."
"Ugh... my legs have no strength at all..."
"You still have to get up. Now we have to do Kegel exercises." I pulled Rene's bound hands forward. "Beginners should do Kegel exercises standing up." Though her trembling legs were visible, I forced her to stand. In case she might fall. I hugged her from the front and wrapped her arms around my neck.
"Hold on tight." The moment our faces met. I reached out and grabbed Rene's buttocks.
"Wh-what are you doing?"
"I told you we're doing Kegel exercises." At my words, she looked puzzled. "What are Kegel exercises?"
"It's practicing tightening your pussy around a cock during sex."
"Huh?" I slapped her buttocks hard with my palm.
-Smack!
"Aah!"
"Tighten your buttocks."
"What? S-suddenly?"
"Yes. Quickly." As I said, she tightened her buttocks, but... "Weak. Tighter!"
"L-like this?" Feeling Rene's buttocks contract and become quite firm, I squeezed them and said. "If the strength loosens, I'll spank your buttocks, so maintain this state."
"Eek!... Hng... it's hard!"
"Do you know how hard it is for a man during sex? What's so hard about lying down comfortably and tightening?" Feeling the strength slowly leaving her buttocks, I spanked them again.
-Smack!
"Aah! It... it hurts!"
"If the strength loosens, I'll spank like this." Saying that, I reset the chronograph on the pocket watch. "Now, if you hold for 1 minute, I'll give you rest time. Try to tighten as hard as possible! If the strength loosens, I'll spank again, so tighten as much as you can!"
"Ugh!" Rene's face turned bright red, seeming quite difficult. I pressed her buttocks with my fingers. This looked simple but wasn't really. The buttocks are a fatty area. You have to accurately feel the muscles inside the fat.
"Hng... it's hard?" Kegel exercises are hard at first.
"Everything is hard at first. Ah? Your strength is loosening?" At my words, not wanting to be spanked on the buttocks, she put strength into her rear. "Ugh!" Before long, a minute passed... "Now rest a bit." As soon as I finished speaking, Rene's buttocks became soft.
"Wh-why do this kind of thing?"
"If you tighten well with your pussy, the master will feel good."
"I... I don't want that kind of praise." She said with a fierce scowl on her face. "My buttocks... hurt." Instead of Rene whose hands were bound, I massaged her buttocks.
"This feels a bit refreshing, right?"
"Leaving aside whether it's refreshing, do I really have to do this?" When she asked with an annoyed face, I nodded.
"Yes. This is extremely important, along with fellatio. Now, rest time is over!" Seeing that a minute had passed, I commanded again. "Try tightening again with strength."
"Al-already? I haven't even rested properly."
"It's only been 3 minutes? Hurry up and put strength in."
-Smack!
"Kyaa! I said it hurts?!" As Rene glared at me with wide eyes, I kneaded her buttocks and said. "Then put strength in, quickly!"
"Eek!" Feeling strength enter her buttocks, I said. "Do you know how hard a man works to satisfy a woman? Compared to that, this is nothing!"
"D-don't talk! The strength will loosen!" Probably because I spoke, I felt the strength leaving her buttocks. Of course, this was also what I intended.
-Smack!
"No! Are you trying not to moan during sex?! You should moan naturally while tightening and loosening!"
"Eek!"
"While exercising like this, answer everything I say!"
"H-how?!"
"Your strength loosened, didn't it?!"
-Smack!
"Kyaa!" Strength entered her buttocks. Now... shall we do this properly? Though not visible, the buttocks hit by my hand would be red and highly sensitive. I gently tickled Rene's buttocks, which had a faint warmth, with my fingers.
"Hng... th-this is weird!" Watching her close her eyes and shake her head, I thought. Planning to do Kegel and spanking at the same time. I'm a genius. I whispered softly into her ear. "How is it? Doesn't the spot that was hit feel good? You bitch."
