Covering Her Mouth
I reached for her pussy first. There was no bigger disaster than going in dry, so I figured I'd give her a little foreplay before we got down to the real thing.
But then—
"Huh?"
She was already soaked. I didn't even need to do anything. Down below, her juices were running like a river.
Come to think of it, she'd already been marinating under the desk for a good thirty minutes. The same way I'd just been watching that blowjob video, she'd been getting a full 4D close-up of my cock. No wonder she was this worked up.
"What's this?"
I said it while glancing at her left hand. At first I'd just assumed it was sweaty. But thinking about it, the hand isn't a place that sweats that much — and even when it does, it dries pretty fast. And yet her left hand was gleaming more than anything else in the room.
That could only mean one thing.
"A-rin. You were touching yourself down there, weren't you?"
That's right. She'd been so turned on she couldn't help herself. She'd been playing with her own most important parts — for nothing but pleasure.
"...Nnh."
She turned her head to the side, embarrassed. I'd noticed this about her before — whenever she got flustered, she had a habit of looking away, as if that would somehow let her dodge the interrogation.
It was a bad habit. It never actually solved anything. All it did was make her shrink into herself. To break her of it, I caught her chin and locked her gaze on mine.
"No. Look this way."
Those big, bright eyes took me in. Her face was getting redder by the second, and my grinning face was reflected in her half-lidded pupils.
I moved my other hand and pushed my middle and ring fingers into her.
A wet squelch. A faint moan rang out at the same time.
"Hah—"
I could feel how slick she was inside. Those slippery walls clamped down around my fingers. I worked the two of them slowly as I scolded her.
"You can't just get yourself off whenever you feel like it. Your stamina's already so bad you always tap out first. You really think you can afford to waste energy?"
It was true. By the later stages of sex, she'd already come one or two more times than I had. Her stamina would tank, and after I'd keep at her for a while, I'd find her completely limp. I did tend to go long, since I didn't get to play with my cock that often... but even setting that aside, her stamina was on the weaker side.
"Hngh...! That's not true... I wasn't tired..."
She moaned as she denied it. From her perspective, wearing out in bed before me — a guy — was apparently pretty humiliating. Well, winning or losing in bed was probably a big deal for a woman. It was tied to her confidence, so it wouldn't be easy to admit.
"Yeah, I already know you're a total lightweight~"
Whether she admitted it or not, everyone already knew Seong A-rin was a pushover in bed. I teased her like that as I promptly shoved my cock into her.
"Hahk?!"
A moan rang out. Something incomparably longer than mere fingers stirred inside her. The head of my cock was knocking against her cervix. I rolled my hips, quietly savoring her reactions.
"Hahk...! Haaang...!"
Once. Twice. Every time I thrust in and out of her entrance, a cry rang out. Those lewd moans slammed against the wallpaper of my place, bounced back, and filled the entire studio.
Wait. Hang on.
Hearing that, I hurriedly covered her mouth. The moment one palm sealed over her lips, the volume naturally started to drop.
"Hey, keep it down. The neighbors are gonna hear."
If she kept making noise, my classmate from the same department who lived next door might get some weird ideas. That couldn't happen. If it did, strange rumors might start spreading around campus. Nothing pissed me off more than people who barely knew me running their mouths about me.
So I'd just hurriedly covered her mouth to prevent that...
"Mmph..."
Squeeze. All of a sudden, her pussy clenched tighter than before — like she had no intention of letting my cock go. It was like something had flipped a switch with whatever I'd just done.
That's right. She'd gotten turned on by what I just said.
Come to think of it, covering someone's mouth was a classic move in rape porn. The kind of thing where the attacker silences a victim screaming for help. Of course, right now I was just muffling moans, not cries for help, and I hadn't covered her mouth with any dirty intentions. But it was more than enough to set the mood.
In that case, I might as well play along.
"Keep your mouth shut and stay still."
I said that and flipped her over. Her curved ass and smooth back came into view. My cock was still buried inside her. I lifted her upper body while staying connected.
"Mmph!"
Her back arched, pressing against my chest. The arm covering her mouth slipped under her armpit, pinning her in place, while my other hand grabbed her stomach to support the unstable position. The only parts still touching the bed were her knees and shins.
This position was, basically, standing doggy style. The technical term was rear-entry standing.
I started slowly moving my cock while still covering her mouth. Every time her ass slammed against my pelvis — thwap, thwap — the impact echoed through the room. I caught a glimpse of pleasure overflowing from her eyes.
"Uurk—mmph—!"
Hearing her moans with her voice muffled had a charm all its own. The thought that I was suppressing something of hers. That feeling of dictating one of her actions. That alone was enough to send a deep thrill through me.
Looking down past her face, I could see two mounds of flesh bouncing roughly up and down. Every time I rammed against her cervix, her breasts leaped upward as if in reaction.
That's when I felt a small moment of awe. Ahh. So that's titty physics. There's a reason that term exists. Those roughly bouncing breasts were art in themselves. Looking at them made me feel good — and if something can move a person with nothing but visuals, what else would you call it but art? And the best part compared to a drawing: this wasn't 2D. This was 4D.
I moved the hand on her stomach up and grabbed her breast.
"Nngh—!"
Every time my fingers moved, that ample breast changed shape. The flesh would dent in one spot and swell up somewhere else. It felt like squeezing a warm, soft water balloon. I made a pincer with my thumb and index finger and pinched her nipple.
"Knhh—!"
A moan leaked out of her. Thanks to my hand over her mouth, it wasn't that loud, but I could tell she was definitely feeling it. Seong A-rin turned her head for a moment and looked at me with pleading eyes.
"Mmph—mmph—"
She looked like she wanted to say something. I ignored her.
"Hmm? What was that? Can't hear you."
I gave the nipple in my fingers a little twist left and right. It wouldn't hurt, but it'd be more than enough to feel. Every twist wrung a faint moan out of her, and her pussy clenched down.
Oh...
I let out a small gasp at the tightening pleasure. This position was a bit of a workout, but it was worth it. Being able to grope her tits while doing her from behind — this was the pinnacle of combining the best of every position.
After twisting her nipple a few more times, the urge to come started building. I gradually sped up my thrusting. Thwack. Thwack. Thwack. Every time flesh slammed into flesh, pleasure crashed over me. Goosebumps ran down my spine.
"Nngh—mmph—hngh—!"
Even with her mouth covered, she kept moaning for me. The sound filtered through my palm and came out muffled. Honestly, a restraint this light could've been broken with a few shakes of her head. The fact that she didn't bother told me she was into this.
Thinking that, I came inside her.
"Kh."
Spurt. Spurt. Thick cum filled her up against her cervix. I squeezed her breasts as I came.
"Hnnngh—!"
Was that last squeeze the finishing blow? Or did the cum flooding into her land the final hit? The moment I came, she started coming too. Clear fluid gushed from her pussy like a fountain. Her arched waist trembled like it was convulsing.
I held her like that for a moment, then let go of both hands.
"Hahh..."
Her body crumpled onto the mattress. The tide from her pussy dripped onto it, drop by drop, and the once-white mattress stained as each one landed. I looked at that and smacked my forehead.
Ah, fuck.
How the hell am I supposed to wash that.
