Drowning in Undine's Depths
A child poor at swimming who falls deep into the water thrashes desperately with arms and legs to survive, but the body refuses to move forward and only sinks deeper. In a vision dyed entirely blue, I still had no choice but to struggle against Undine's mischievous prank.
"Ugh... mmph..."
I furrowed my brow at the foreign sensation flooding my mouth and nose, yet I couldn't reject it since it kept me from suffocating. More than anything, I had no room to worry about that right now.
Eight... eight... ♡
"Grrruuup..."
How should I even describe this? The moment her cool, soft flesh touched me, my manhood stood rigidly erect as if my body remembered it all. Undine began skillfully stimulating it. She pressed tightly from the base to the tip, giving just the right amount of pressure, then rotated her elastic flesh in different directions. Those firm protrusions she must have created on the spot rubbed relentlessly as they spun. The heat rising in my manhood made her body feel even colder, trapping me in a strange pleasure that felt good yet kept climax agonizingly suppressed.
...Yet it felt familiar. This pleasure was so familiar, as if I'd experienced it several times before.
Aga, holding back isn't good for your body. Come on, shall we let it out~?
At the sound of her gentle voice echoing in my head saying "let it out," a shiver ran through me. I thrashed again to escape, but of course I couldn't get free unless she released me. I still didn't fully understand her purpose, but this couldn't continue. There had to be some way...
I already know all of Aga's weak spots.
I flinched...! But she gave me no time to think, her sticky tentacle wriggling between my buttocks. I could guess her intent from its position alone, and a chill raced down my spine. This... surely she wouldn't... But she'd already called it a weak spot, so there was no hope. Cornered like someone at the edge of a cliff, I was grasping at straws. The team leader had strictly warned me never to attempt a connection with her, but this situation was beyond my control.
Undine...! Stop, that's enou—
Why...? Ugh... ugh...? Haah...?
The sudden backlash of the connection hit both of us hard. I confirmed that the thick tentacle near my perineum had fortunately paused, but once I realized how her feeding worked, I couldn't help regretting the link. I'd already seen how she could pinpoint emotions I didn't even recognize as guilt. She savored emotions directly as she consumed them. The reason my climax had been building yet stayed suppressed was because she had been steadily feeding on the rich pleasure I felt. Now, thanks to my ability—which doubled sensations instead of following conservation—she could feel exactly what I felt at the same time.
"Ugh...!"
Ahaang...?!
This meant she no longer needed the feeding process. With the urge to climax having built to its absolute limit without release, stopping the feeding caused it to surge all at once.
Spurt...! Spuuuurt...! Spurt, let...!
Just as she said, white fluid gushed in thick pulses from the slit at the tip, visible through her transparent body as it slowly mixed and dissolved into her blue form. It was an intensely stimulating sight—watching my own semen being released inside her and then gradually absorbed.
Undine... what is this...
Aah... ugh... Aga, what is this...
...Now I understood. The reason I'd always felt unpleasant lethargy instead of pleasant exhaustion after losing consciousness. Until now, I'd been violated by her every time I blacked out, yet I'd never once climaxed properly. Because she kept consuming the pleasure I felt, my body had writhed in ecstasy without ever reaching release, spilling semen like a wet dream. Repeating this for hours, then visiting her containment room again as soon as my stamina recovered, for an entire week—it was a miracle my body hadn't broken down.
This is... another form of my ability. You can feel what I feel, and conversely... I can feel what you feel.
...I see... So this feeling... ♡
Your voice... sounds lewd...
...
Even with my mouth and nose blocked, I'd found a way to communicate my intent, but any lapse in focus let my inner thoughts slip out.
Ah... no, just now that was...
It's fine... Climax is... just a stronger, more intense feeling like this, isn't it...
She paid little mind to my slip, savoring the lingering pleasure in a voice drunk on ecstasy. Her feelings toward me were simple curiosity. Like discovering the most efficient way to pull the lever on an endless ice cream machine. Nothing more. No malice at all.
...That was what made it scarier. Undine and I weren't so different that we couldn't converse easily, yet the fundamental gap in our thinking could never be bridged by ordinary means. Still, I believed this: even if our values differed, her kindness remained unchanged. All I had to do was show her the way.
Right now... I'm extremely flustered... and embarrassed.
...I can feel it... My body feels strangely warm.
Of course... After being caressed all over while naked and forced to spill semen helplessly, the post-climax self-reflection naturally brought shame.
But... I don't feel like I dislike it... or find it unpleasant.
...Yes.
That's definitely because it's you, Undine. I never imagined it would come to this... but I do owe you a debt of gratitude.
Honestly, it had felt good. If I claimed I hadn't imagined something like this whenever her moist, soft, slime-like body pressed against my bare skin, it would be a lie. Knowing she harbored no malice or lewd intent made it awkward to get angry or point it out.
...To you, my body must seem incomplete and inconvenient, with plenty of unnecessary functions. But how about experiencing it once, this time?
Knowing how sincerely she respected others' wishes, this was as good as having her answer already.
Ufufu... I see... All right.
As expected, Undine agreed without the slightest hesitation. True role reversal had become possible. In this situation where our bare skin pressed together without gaps, trembling at every pleasant sensation, knowing she was experiencing it too brought me relief. If the stimulation she gave returned to her as well, she wouldn't be able to go too far...
Thud...! Squish, squish...!
Ah...?
A bizarre, unpleasant sensation—far more alien than the foreign feeling filling my mouth and nose—left me staring blankly ahead for a while.
Urgh...?
Separately from that, a thick, elastic tentacle had pushed into my body through the one place a man should never allow, pressing firmly against something inside. My manhood, which had just gone limp after being tormented to climax, instantly stood rigid again.
T-This is, Undine... wait...
I've been studying your body quite thoroughly these past days... It's really fun how pressing here makes it stand right up.
Fun...?
Press... press...!
Urgh...?
Hnn... haah...
At least the tentacle behind me didn't start moving back and forth in that terrifying way. But when Undine began rubbing the same spot she'd used to make me erect—this time more like caressing—an electrifying pleasure swept through my mind, strong enough to erase every unpleasant sensation of intrusion. She felt it too, and the moans that escaped us almost simultaneously made me realize something else.
...I'd overlooked the most important thing.
Ah...
I'd expected her to hesitate when placed in the same situation as me, but this was no different from kindly teaching an innocent woman who knew nothing of masturbation exactly where her sensitive spots were and how to feel good.
Then... I can keep going, right?
