Chapter 14: Chest Development (2)
"Pleasure... stacking?"
"Yes. By stimulating the nipples like this, a hot, floating sensation gathers throughout the body, and a pleasure that has no outlet gradually accumulates."
With fingers coated in slick oil, Silvia gently took hold of my right nipple. The already-hardened nub was caught helplessly between her thumb and index finger. She slowly started to rub her fingers, stimulating the nipple bit by bit.
"Hnngh."
Lying to my left, Seril followed Silvia's lead and began her Nipple Stimulation in earnest.
"Now~ it's time to feel good~"
Seril grabbed the area around my areola with her thumb and middle finger, stretching it wide, then tapped the protruding nipple in the center with her index finger. Each time her finger lightly brushed against the nipple, a pathetic moan escaped my lips.
"Ngh!"
With my areola and nipple so exposed, the sensations seemed to have become even more sensitive. As one side was being tapped and the other was being slowly rubbed, a throbbing warmth began to build in my chest.
And gradually, an erotic feeling... a feeling of arousal began to build, enveloping my entire body.
"Haah... haah..."
It wasn't a powerful pleasure like an ejaculation. But a subtle, insidious pleasure was slowly spreading from my nipples, steadily filling my entire body.
My heart began to beat faster, pumping blood through my entire body. My head grew hazy, and I felt as if I was floating... This pleasure, with nowhere to go, roamed my body, searching for an exit.
Silvia and Seril pressed their lips to my ears, blowing warm breath as they spoke.
"How does it feel? Don't you feel a certain frustration, a certain lack?"
"Heehee~ Your panting is so cute~"
"This pleasure with nowhere to go doesn't just disappear. It eventually builds up and seeks a place to erupt. Stimulating the penis at this point would allow you to enjoy a considerable ejaculatory pleasure, but..."
"No matter what, we're not going to touch your cock~"
At her words, which felt like a death sentence, I writhed in a daze and pleaded.
"My cock... please touch it..."
If they touched my dick now and let me ejaculate, it would feel incredible. And this frustrating, hot feeling would disappear. But Silvia did not allow it.
"You may not. Penis stimulation is prohibited."
Twinge-
Silvia gave the nipple she was holding a light pinch, and a bolt of lightning shot through my chest.
"Hyaht!"
"If we were to stimulate the penis now, there's a possibility the pleasure nerves could be miswired. It is not good for your Development."
"That's right. Your cock is sealed. And your hands are sealed, too~"
Squeeze-
Silvia and Seril grabbed both of my hands, pinning them so I couldn't touch my dick. Unable to do anything, I could only writhe and let out ragged breaths.
Just as I had given up resisting and was lying there dazedly accepting the pleasure, Silvia licked my ear and whispered in a low voice.
"Normally, when nipples are touched continuously, they grow tired and lose sensation for a time. However, that does not seem to be the case with you."
"Are you already fully developed~? You're no different than a real woman's nipple~"
At Seril's words, which wounded my pride, I shook my head.
"I'm not... a woman..."
Then, I bucked my hips, showing off my stiffly erect cock. As long as this Symbol of a Man was intact, I was a man.
Silvia's gaze flickered down to my cock before she whispered in my ear again.
"Biologically, that might be true... but a man who feels pleasure from being surrounded by women and having his nipples stimulated. Isn't that, in fact, no different from a woman?"
"That's right~ Don't try so hard to deny it. If you just accept it all, it'll feel even better~"
Seril, too, whispered stickily as she licked my earlobe. All the while, her fingers continued their rhythmic, teasing touch on my nipple, barely grazing it again and again.
There were moments when the steady stimulation would suddenly stop, becoming irregular, and each time, my nipple would flush as if in frustration. Feeling the pleasure in both my breasts, I listened to their whispers as if under hypnosis.
"And anyway, a cock that small is as good as not having one at all~"
"N-No, it's not!"
Even in my daze, I shook my head forcefully. It might be small now, but once I returned to my original body...
"It's not that different from a clitoris, is it?"
"It's not! It's bigger than that!"
Of course, it couldn't compare to my original, but it was a decent size... or so I thought. But Seril didn't seem to think so.
"Aww~ They're practically the same. Should we just cut it off? It's useless, anyway."
"N-No, you can't do that."
As I freaked out, Silvia stopped Seril.
"Seril. Do not say such scary things. You are breaking his concentration."
"Okaaay~ I'll only say naughty things then~"
Only then did I relax and focus on the pleasure again.
*
How much time had passed?
"Rub rub, rub rub. Let's feel good every time I touch your nipples~"
"For now, you may let go of everything and just feel good. Think only about feeling good."
I couldn't think anymore. The hot sensation spreading through my body and their voices whispering in my ears were all that filled my head.
"Haah... haah..."
"Let's become a woman~ Let's have a huge orgasm from having your nipples touched~"
Their lewd whispers filled my ears. Warm breath and moisture. Their voices echoing in the Bathing Chamber, and a strange sense of openness.
The strange pleasure spreading from my chest, areolas, and nipples. The dazed, hot sensation filling my head. The frustratingly pleasant euphoria spreading through my body.
I panted repeatedly, erased all thought, and focused my mind solely on the pleasure rising within my body.
Vmmm-
Then, I began to clearly feel the sensation in my perineum, which I hadn't been paying attention to.
It was the vibration from Hilda's tail, which had been subtly stimulating me.
"Hnngh."
At that, the frustrated, homeless pleasure that had been spreading from my nipples began to gather toward my perineum, where Hilda was stimulating me.
Thump- Thump- Thump-
At the same time, my heartbeat began to sound as loud as a drum, and my mind started to go white.
With a sensation like my whole body was floating, the condensed pleasure began to burst forth all at once.
"Haaaah..."
I stuck my tongue out, my eyes rolled back, and I threw my head back. My back arched like a bow, and it felt like the muscles in my arms and legs were twisting from the excessive force.
Flick-
Even in that state, Seril flicked my nipple with her fingernail. My body jolted as if struck by an electric current.
"Hic!"
Watching my reaction, Seril spoke, amused.
"Ah. It's here~ The Female Orgasm~"
"To succeed already, even if it is faint. You are truly overflowing with talent."
Silvia, too, didn't stop rubbing my nipple with her fingers. It was as if an electric whip was continuously injecting pleasure into my nipple.
"Hic, hic."
My body began to convulse in time with the vibrations from my perineum. I started hiccuping. They whispered ceaselessly into my ears as I writhed.
"Let go~ let go~ Just give in to the pleasure~"
"Let's fill your mind with only pleasant thoughts."
"Feel it with your nipples and your butt, and let's go all the way~"
"Try to feel the pleasure of a woman."
Silvia pressed down on my lower belly with her other hand.
It was near my bladder, but for some reason, the pressure there intensified the throbbing in my perineum.
"Although you lack a uterus, men also have a similar place where they can feel pleasure."
The throbbing in my belly grew stronger. Against my will, my butthole began to clench and unclench on its own. With each pulse, the pleasure grew stronger and stronger.
"Hic, hic, hic."
"Oh my, has it already become an Ass Pussy? That was fast~"
Hilda, who was rubbing my perineum with her tail from below, giggled. For several minutes, I writhed, battling the pleasure that filled my head like a dense fog.
"Heuk, heuk, heuk."
"Now, then, let us conclude."
Silvia, Seril, and Hilda stopped their stimulation, and while I was still floundering in pleasure, they lifted me, Air Mat and all, and headed somewhere.
"Hee, hee."
The place I arrived at, rolling around on the Air Mat in a state of trance, was in front of a tub.
Though it was a tub, its size and depth were a little different from a normal one. It was deep enough to drown in if you weren't careful.
As the stimulation on my nipples and perineum that had given me pleasure disappeared, the pleasure that had filled my body also began to fade.
But unlike the fleeting pleasure of ejaculation, the afterglow lingered on.
With a limp body, I barely managed to open my mouth.
"Wha... what are you doiiing..."
"You will know once you experience it."
Swoosh-
Seril and Hilda tilted the Air Mat they were holding, and I, lying on top, slid into the tub without any resistance.
Splash-
"Hyaat!"
I fell into the cobalt-colored liquid and flailed. The shock of the water woke me from my dazed state.
My feet couldn't touch the bottom of the tub. At this rate, I would drown. I fumbled for the edge of the tub and barely managed to hang on with my hands. But.
"Heehee. Your whole body has to be submerged for it to be effective. Heave-ho~"
Hilda laughed, amused, and pried my fingers from the edge of the tub.
"Ooboob... oobooboo..."
Having lost my support, I sank straight to the bottom of the bathwater.
