"...What will you do with me if you succeed in getting me pregnant?!" I ask Delphina as I try to move my hands, but the shackles are too strong for me to do anything.

"I'll release you and let you go to the Abyss, but only after the child is born since I'll be taking it with me. My magic only blocked your passage, but you appeared where you were, so as soon as I free you from here, you'll return to your starting point."

"That means you'll appear in the Abyss..." she says as a few vials appear in her hand and she starts drinking.

"...And... what will you do if you get a child? I won't be with you to take care of it and..."

"It doesn't matter. I will go to your castle and start living there so our child can have contact with your older sisters... besides, you are going to the Abyss. What would I do if you died there?"

"Having a child means everything! It's a punishment for you, it's proof of our love and... it's a guarantee that I'll have a piece of you even if you die." She speaks with seriousness as I see her penises becoming erect. The two of us naked like this would be erotic if not for the situation.

'...' I take a deep breath, trying my hardest to calm down. I just need to endure this. And even though my passives are deactivated, I still have my normal adaptation. I'm 100% counting on the fact that she won't last very long.

'If when this is over I'm just going to be thrown back into the Abyss, then I'll barely have any time to actually adjust to everything...' I feel a bit angry about this. Delphina chose the most inopportune moment possible for this.

"You know, Delphina, I never expected you to be the type who likes to handcuff others," I joke as she grabs my waist.

"...O-ow..." I let out a sound of pain, feeling how tightly she's squeezing. It's strong, really strong. It's not a gentle, caring hold; she's holding me as if she's brutally immobilizing me.

"You know, Pandora, ever since we started our relationship, I decided to accept more of my species... I never asked myself how 'my' race behaves... but thanks to you, I studied quite a bit."

"The mermaids are my creation, but I gave them so little importance that I never noticed how different they are. They all have biologies based on marine animals in general; they evolved over time for that."

"And of course, sharks like me are included, although they are relatively low in number because they are a type of solitary mermaid that doesn't interact much with other mermaids of different types..."

"Many of their behaviors are similar to mine... so I decided to accept this side of them and copy a few things..."

'Oh great... as if I needed a biology lesson about shark behavior...'

"Could you just get on with it? Time might be slow here, but I don't want to have to sit here listening to you teaching me like a child just because I do the same to you," I say sarcastically, knowing she's doing what I've done to her.

"...Your disinterest is painful... truly." She squeezes even tighter, making me writhe in pain, the high sensitivity and deactivated passives only increasing the painful sensation.

"..." I look at Delphina, seeing her gills opening exaggeratedly and starting to vibrate a little as if she were breathing rapidly, an unusual thing I've never seen happen since she normally keeps them closed.

Immediately my body reacts, thrashing about as if it were a warning. I guess because we're both non-human species, our bodies more or less understand what's happening.

And because it understands, my body feels uncomfortable being "intimidated" by her in this way.

Her tail becomes rigid, making stronger, more agitated movements while I genuinely want to push her away from me.

'This is so... uncomfortable...' I've never felt like this before, because it's not exactly sex that she's about to start; it's literally just animalistic reproduction.

'Karma really comes to collect...' I did something similar to Zephyra, and who would have thought, now I'm going to suffer the same.

"Hey, careful, there..." I say when she pulls me, forcefully aligning me. The feeling of the friction of my back on the ground along with my shackled arms is unpleasant, with her touch also being unpleasantly strong.

Her penises soon become rigid and throb in a somewhat "frightening" way, changing from their normal pinkish tone to a more reddish color, a clear increase in blood activity in her body.

Her pupils dilate briefly before narrowing like blades, staring fixedly at me, making my body shiver from being dominated.

'I never expected my body could react like this... Delphina really can be... unique... when she's the active one...' My private parts become completely wet as a physiological response to the situation.

'I can't believe I'm reacting to this situation...' Even though nothing has really happened yet, our bodies are already reacting, and she now looks ready to fuck me.

"...Any last words?" she asks in a cold, tyrannical tone, similar to the Delphina before we had our first relationship.

"...When you lose, I want to leave." I'm not comfortable with the situation, so when she collapses from not being able to handle the sex, I want to get out of here.

"...Fine. If I can't handle it and end up fainting or something similar, I will let you go... but until that happens, I won't stop until you are pregnant." She speaks with a smile that shows all her sharp teeth.

"So, Pandora... I hope your regeneration is in working order... or I might end up killing you by accident..." She speaks with a seriousness about me dying that is truly frustrating.

'I'm not going to die from sex; that would be ridiculous.' She moves her waist, pulling it back a little and leaning back to align the tip of her lower penis directly with my private parts.

She still holds me firmly in a painful grip as I prepare myself, hoping the sensation won't be too bad despite the hypersensitivity.

However, she quickly thrusts everything in at once with force, pushing me back. The sudden invasion with extreme strength is so unexpected that my brain freezes before processing what happened.

My belly becomes convex because her penis is large and thick, while her other penis touches my belly exactly above the one inside me, giving a general idea of where it is more or less.

"..." I feel a warm liquid running down my nose and notice tears streaming down my face. I look down and see blood dripping from my nose.

"!!!"

'Nosebleed?! Just from her entering?!' She literally caused a sensory overload so intense that I couldn't even feel the penetration; my brain literally overloaded from just that stimulus.

"..." I don't move, and she doesn't move, staring at the blood running from my nose. I feel that if I move, I'm screwed; any stimulus now could make my brain kick back into gear.

My heart races madly, real anxiety surfacing with the possibility of me starting to feel again.

"H-Hey Delphina... h-hahaha, things... are a bit strange... could you just stay still for a few minutes... just until I adjust." I say nervously, my voice coming out with a strange tremor while I can't feel my lower parts.

My brain literally stopped responding to the sensation because it couldn't handle it, but if she moves, I'll obviously start feeling again, and I honestly don't want to feel whatever it is that happened.

Because if my brain overloaded from just that, I could honestly go insane if I start feeling her inside me. I'm on the verge of snapping at any moment.

'Damn hypersensitivity!! What the hell is this?! How did just her entering me make me start having a nosebleed?' I become genuinely worried about the long-term effects this will have on me.

"The smell of your blood, Pandora... is quite exciting..." she says as I feel the "hooks" on Delphina's penis opening. I had totally forgotten that her penis is quite unusual.

Immediately my body arches forward as I feel like I'm going insane. The sensation finally "loads" in my brain; I feel the penetration tearing through my flesh as if it were ripping apart my body and soul.

The feeling of dragging and pressure is the strongest sensation I've ever felt in my entire life. It's not pain, but it's so intense that it's worse than if it were pain. My chest rises erratically, my heart beating wildly as I feel like I almost fainted.

'T-This... s-so intense...' My brain throbs; I feel as if someone hammered my brain directly. I never knew a penetration could be so incredibly intense.

"..." When the first shock finally passes, all that remains is the uncomfortable feeling of her inside me. Her penis being squeezed by my pussy is almost painful, as if the hardest, hottest thing in the universe is being shoved inside me.

My pussy feels like it's on fire; the heat from her penis, which wasn't much before, now feels like it's burning me from the inside with my sensitivity.

And of course, the sensation only makes my private parts squeeze even tighter, contracting abruptly, which only increases the contact.

"Hmmm... you're losing to just this, Pandora... now you know how I felt when I could barely handle you touching me." She speaks proudly while I don't respond because even talking seems like too much for me.

"GHMMM!!" When she pulls her penis back, I almost scream. The sensation of the "hooks" on her penis scraping against my flesh drives me insane, making my eyes roll back.

No aphrodisiac would ever come close to the crazy sensitivity my adaptation has led me to have. I start drooling as my gaze at her becomes blurry.

"GAAAHHhH" I let out a real scream when she thrusts everything inside me again. The feeling of my uterus being crushed against itself because of the giant size of her penis is maddening.

"Pandora, you're being too exaggerated. This is going to make me feel bad... is that it?! Are you faking to trick me?" She seems to become furious when she reaches that conclusion.

"Even at a moment like this you still try to deceive me?! Damn you... I can't believe this!... I guess that was to be expected from you." She lets go of my waist and snaps her fingers. Immediately, a gag that is like a small rod appears in my mouth, and a blindfold appears over my eyes as she goes back to holding my waist.

"Hmm!?!"

"I made these especially for you! You won't be able to break or remove them. I feel like if I hear your voice and see your eyes, I'll be too lenient with your punishment and go easy on you unconsciously... but..." She pulls out and thrusts everything back inside me brutally, making me struggle against her, who holds me firmly in place.

"You don't deserve my mercy after so many lies and broken promises!! You will learn not to deceive me again, Pandora!" Without meaning to, Delphina makes the situation even more infernal for me.

Naturally, when one sense is restrained, others amplify so the body can perceive the world. With her covering my eyes and mouth, naturally, touch and smell increase.

It works immediately. The sensation that was already maddening becomes indescribably worse for my sensitive body, making the tears flow freely even though I don't want them to.

I have never before hated my ability to adapt so much, because this damn adaptation that made me sensitive has just created a method of torture that Delphina is unknowingly subjecting me to.

'A few hours?! Can I really last a few hours?! I WON'T LAST EVEN 10 MINUTES OF THIS!!' I believed I could hold out until Delphina tired, but like this, I won't last even minutes, let alone a few hours.
