No. 13's Hidden Desires
Plap! Plap! Plap! Plap! Splurt..!
"Nngh...! Gah... hngh...!"
"Me too... now... ngh... hngh...!"
Slap! Slap! Slap! Slap! Slap! Slap! Splurt..!
"Ghh...!"
Squeeze...! Spurt spurt spurt...!
With her petite body pinned face-down on the bed, I wrap my arms tightly around her from behind and drive my hips forward, pouring thick semen deep inside without hesitation. From this angle it almost feels like I'm forcing myself on her, and the thought sends a shiver down my spine.
"Ngh, hngh... hngh..."
Pressing my full weight down on her makes her moans sound strained and almost pained. But this is exactly what she asked for.
"...Hah... hah..."
After several rounds—perhaps because it's been a while—I'm still rock hard when I finally pull out of her tight heat. A moment later, thick white fluid trickles out in lazy pulses, already marking her most intimate place.
"Hah... hah... hngh, next time... could we do it facing each other...? Please?"
Normally she speaks casually with me, but the moment the mood shifts and that switch flips, she starts using polite speech again.

"And... could you choke me a little too...?"
At work she's one of the few reliable, normal people around me. But the second I get her on a bed, she turns into this.
"Haa, you really are a pervert. I heard you've been asking the team leader about my schedule nonstop."
"Yes... I just wanted to have lots of sex with Master..."
Her honesty is almost embarrassing. Her hair, dyed bright yellow because she hasn't had time to touch up the roots lately, shows a hint of black at the scalp. I wouldn't mind seeing her natural black hair again someday.
"You usually go shopping when you're stressed, don't you?"
"Hngh... being roughly pounded by Master feels even better..."
Her normally sharp eyes are now rounded and obedient, wearing the gentle smile of a loyal puppy. Since neither of us has been drinking, hearing her call me "Master" still feels a little awkward—though she's completely sober too, which is impressive in its own way.
"...How do you even get this broken?"
"Hehe..."
When my honest thoughts slip out laced with mild contempt, she actually gets off on it. Still, she's been working hard lately, so she deserves a reward.
"Ahn..."
I grab her slender wrist, flip her onto her back, and settle between her legs in the position she wanted. She melts with a happy little sound.
"You like doing it with me that much? I saw that flashy toy collection earlier."
"It's really different... Master's reaches all the good spots inside... hngh, and pounds so hard and deep..."
What kind of expression is that? I worry she'll talk like this in front of other people someday. That aside—
"You said you do it from behind when you're alone, right?"
Squelch... squelch! I press my cum-slick cock back into her messy entrance and ask. She lets out a shaky breath, her expression suddenly brightening. She looks genuinely pleased that I brought it up... though I can't hear her thoughts right now.
"Hngh... th-then..."
"...?"
"Would you like to try it from behind too?"
"...Is that okay?"
The question leaves my mouth without hesitation, which is a little embarrassing. But who wouldn't be curious after never having tried it? Even when she wore that bunny-girl outfit last time, the sight of her pretty little hole kept drawing my eyes. It's not that I have a particular preference for it—it's just that ever since she mentioned she sometimes plays with herself back there, the image has stuck in my head.
"Ngh."
"Master...?"
"No, it's nothing."
Come to think of it, I've already experienced being taken from behind first—thanks to Undine. The shame is real.
"Suddenly... it's getting bigger inside... hngh!?"
"..."
Shame aside, my body clearly remembers the pleasure Undine's slick tentacles gave me. It's fortunate there's a place to put this newly rigid erection.
Squelch squelch, slap slap slap...!
"Ah! Hah, hngh... this feels so good...!"
"Don't moan so loudly. Nero might hear."
"Hngh, hah... then..."
"...?"
She raises one hand and points at her own throat with her index finger, smiling meaningfully. My vision goes white. If she's so worried about the noise... she's basically daring me to shut her up myself.
"You..."
Since I can't hear her inner voice right now, it's hard to tell exactly when pleasure tips into pain. I was trying to hold back, but this kind of provocation makes it impossible.
"Khh...! Ghh...!"
I squeeze her delicate neck hard enough that it feels like it might snap and piston my hips like a madman. Her body jerks violently in response. Every time a choked, pained moan escapes her open mouth, blood rushes to her face, turning it bright red. Her insides clench with desperate survival instinct, gripping and spasming around me.
Squeeze...! Squeeze...! Tight...!
"...Khh... ghh, hngh..."
"Hah... hah...! Hah...!"
Knowing she won't last much longer, I keep my hips moving at full speed to finish quickly. Plap! Plap! Plap! Plap! Plap! Plap! Plap! Plap! Splurt! Squelch squelch squelch squelch...!
The filthy mixture of my earlier release and her fluids splatters messily between us with every thrust.
"Ngh... ghh... hngh...!"
Her struggles grow wilder as she nears her limit, tears welling at the corners of her eyes. The sight sends a sharp spike of dark pleasure straight from the base of my cock to my spine.
"Hngh...!"
Spurt spurt spurt spurt...!! Spurt! Spurt...!!
A dizzying orgasm rips up my spine and slams into the top of my head. I lose myself in the sensation, barely noticing her thrashing beneath me until it's over.
"...Ah."
Only afterward do I realize her resistance has weakened. I release her neck—my knuckles white from how tightly I'd been gripping—and she immediately starts coughing.
"Khh...! Cough, cough! Cough...! Hngh... cough...!"
She comes again and again, her lower body trembling violently, completely wrecked moans spilling from her lips.
"Hngh... hah... ghh..."
Squirt, squirt...! ...Drip...
"W-wait...!"
"Aheee..."
Which is how we ended up here—freshly showered and sitting together on the living room sofa. The washing machine hums in the background, spinning the sheets and blankets. It's a little embarrassing... and oddly sweet.
I never expected to make that much of a mess.
"...Sorry. I couldn't control myself."
"Mm... it's okay. It was rougher than usual... but I liked it more."
I'm glad she enjoyed it, though I'm a little worried she'll start asking for even more extreme things from now on.
"Ahem..."
I clear my throat and pull her onto my lap. When she glances back at me with those sharp eyes, I feel an overwhelming urge to lick her. Maybe it's because those eyes—usually so pointed—are now filled with soft affection directed straight at me.
"...We just washed up, and you're already hard again."
"Mm."
"This is... a natural reaction, I suppose."
"You don't have to hold back with me. In fact, treating me roughly makes me even more excited."
"Treating you... you..."
I'm only wearing the underwear and T-shirt I came in, and she's in a similar state—nothing but a T-shirt, no bra. The scent of her freshly showered skin is intoxicating. Just as I'm about to push her down on the sofa and take her again, she suddenly stands and walks over to the kitchen table.
She pours a glass of water and picks up a small paper box.
"...Almost forgot."
"What is it?"
"These. I bought birth control pills."
"..."
Ah... I've already finished inside her multiple times today without a condom. I feel a twinge of guilt for making her take them so diligently, but at the same time—inexplicably—I'm incredibly turned on. The fact that she keeps them in the house because of me... that alone is strangely arousing.
"You were planning to do it with me today, weren't you?"
"Well... yeah, I guess..."
She doesn't even try to deny it. At this point, there's no point in pretending otherwise.
"..."
The sun still hasn't set. She called me over around noon, and we've been going at it like animals for three or four hours now.
"So... um, are you still thinking about trying it from behind?"
She's picking up from earlier. Do I want to try it? Of course I do.
"...Not against it."
Very much in favor, actually.
"Th-then... I'll make proper preparations next time..."
"You need preparations for that?"
Her face flushes bright red at my question. Honestly, I'm dying to know what's going through her head right now, but I have no way of finding out. Is she imagining the details and getting embarrassed all by herself?
"Of course... it's necessary. In various ways..."
Her completely flushed face is adorable. I think I'll go for another round after all.
"Kyaa...?"
I rise from the sofa, approach her, and wrap my arms around her from behind. Leaning close to her ear, I whisper kindly.
"Turn around, lean on the table, and stick your hips out."
"Hngh... yes..."
She obediently presents her rear to me. I grip her waist with one hand while the other tugs down my underwear. My already-hard cock springs free and slaps against her thigh before settling heavily between her cheeks.
After our short rest, it's regained most of its earlier vigor. She seems to feel it too—her entrance is already growing slick with anticipation.
"You said preparations were needed, so for now I'll settle for this hole. Clench properly, got it?"
"Hngh, yes...!"
It wasn't until much later—after I'd thoroughly used every surface in her living room and left her completely exhausted—that I was finally able to head home. I even hung up the laundry and cleaned everything before tucking her into the sofa and leaving. By the time I finished, evening had long since passed.
"...I told Nero I'd be back before dinner."
