I Came Inside My Friend's Mom
I thought something felt off, but the moonlight soon vanished again behind the thick clouds.
With my vision cut off, the sense of wrongness from a moment ago faded along with the alcohol.
I couldn't keep thinking about it any longer.
There was no room for deep thoughts in the middle of sex, and it would have been rude to the woman offering me her pussy. Besides, that pussy was squeezing me far too well. The pleasure was overwhelming.
It clung to my cock from the entrance, tight and unused, as if it had never been touched before.
It wasn't tighter than Subin's usually was, but the structure of the pussy itself felt completely different.
There were far more vaginal folds, tangled in complex ways that stimulated me with a fresh sensation every time my cock moved.
Every ridge of the vaginal walls seemed alive, thrashing in violent reaction as if tasting my cock for the very first time.
That novelty was pretty nice in its own way. I began to rock my hips slowly while still buried inside her.
My cock, which had only been halfway in, sank all the way to the hilt with a wet, squelching friction.
"Ah, haah…."
A hazy moan slipped from Subin's lips.
Her insides were incredibly hot. I marveled a little at the heat.
Was it because the alcohol had raised her body temperature? Or was my cock simply that good for her?
Worried she might be getting too warm, I stripped off the top she was still wearing as well, leaving her completely naked.
Then I started fucking her again.
—Schlick, schlick, schlick!
I gradually picked up speed. Matching it, the pleasure grew uncontrollably intense.
I gripped her hips and swung my waist in a steady rhythm.
"Ah, uh, euh, haaah…?"
Still skewered on my cock and rocking, Subin finally made a sound like her mind was clearing. Her big ass jerked hard.
She couldn't understand why something kept slamming into her plump cheeks. Her body unconsciously tried to pull her hips forward, away from me.
Of course I didn't let that movement escape. I seized her pelvis firmly and yanked her back toward me, then drove in even deeper.
—Slap!
"Hyaaah…! Ah, ahng, ahng♡ Wh-what…?! Who is…."
She tried to turn her head with a dazed, moan-filled voice.
I gently but firmly pressed Subin's head down into the pillow.
I intended to fuck her quite roughly tonight.
Of course I wasn't going to crush her so hard she couldn't breathe. I just wanted to keep her from talking too much.
In my experience, women sometimes found pleasure in this overwhelming difference in strength.
The oppression they rarely felt, the helplessness and fear of being unable to resist by force—those things seemed to stir the female instincts sleeping deep inside them.
So, with the alcohol already in her system, I pressed her head down and told her to become a perfect bitch for me.
Subin flailed a hand backward as if telling me to stop. Drunk as she was, the motion was painfully slow.
I took it for Subin's usual teasing. After all, this level of intensity was nothing compared to the sex we normally had.
Just a few days ago she'd stripped naked in front of Chaerin, licked Chaerin's pussy, and joined a threesome. Sometimes she even let me choke her while we fucked.
I smiled behind her. My future wife Han Subin was so thoughtful—she'd noticed my bad mood and was comforting me with her body, telling me to pound her as hard as I wanted.
Just looking at her from behind made me so hard and so fond of her. So I whispered against her ear.
"Just like you said earlier, I'll fuck you senseless. Don't worry. I'll make you feel so good you pass out."
"Mmmph!"
Subin flailed her arms harder while trying to say something.
I thought she was saying she loved me, so I kissed the white nape of her neck.
—Smack!
"Got it. I love you too."
"Hnnngh…♡"
Her nape must have felt especially good tonight; her pussy twitched and clenched even tighter around my cock.
Marveling at that snug grip, I swung my hips harder.
—Thud, thud, thud!
I pulled out halfway and slammed back in, savoring every inch of my bitch's pussy.
Every time my deep-thrusting cock knocked against her cervix, Subin's lewd body thrashed and shook on the bed.
Even I was starting to lose my reason to this masterwork of a cunt.
"Hwoo, hwooo…! Hwooo, euhngh♡"
At some point Subin moaned in the lowest tone she'd made all night, and her pussy convulsed violently. Her climax had begun.
I didn't miss the moment and deliberately kept pounding.
—Slap! Slap! Slap!
Overwhelmed by the excessive pleasure, her huge ass struggled desperately to escape my cock.
Subin tried to crawl forward. But my hands locked onto her hips just as before.
—Tremble…!
Her fingers, stretched out behind her, quivered. The blazing heat inside her felt incredible.
My piston thrusts, which had been mechanically targeting the deepest points of her pussy, had long since turned into the movements of a mindless beast.
What we were doing had stopped being sex ages ago; it was pure, vulgar mating.
—Squirts!
In the end, love juice briefly sprayed from Subin's climaxing pussy.
Her cunt contracted madly, clinging to my cock as if begging me to stop this rough treatment.
Unfortunately for Subin, I didn't stop. I pressed her head down even harder and stabbed into her pussy with my cock.
"Hguuuuh! Kkeuh♡"
As if trying to resist an oncoming tsunami, Subin clutched the bedsheets with all her strength.
But something like that could never withstand the massive wave of orgasm.
I kissed her cervix—now extremely sensitive from climax—with the head of my cock over and over while whispering dirty things into her ear.
"Your pussy tastes even better than usual tonight. Did it feel that good?"
As I fucked her, the moonlight that had been hidden by clouds revealed itself again. The room brightened faintly.
Together with the filthy wet sounds of her soaked pussy swallowing and releasing my cock, our vulgar forms became clearly visible.
Every time my cock gouged along her winding vaginal walls, I could even see her soft pink anus twitching.
It hadn't been developed yet, so the hole didn't open, but I could see her putting force into her ass from time to time.
I gently stroked the wrinkles around Subin's anus with my thumb and spoke.
"Come to think of it, you asked me to train your ass today, right? Want me to stick my cock in later?"
Hearing that, Subin trembled as if she were hearing it for the first time tonight.
Then she shook her head violently left and right. Anyone watching would have thought she really hated the idea of being fucked there.
I paid no particular attention to Subin's body language. I had clearly watched her take the enema pill for anal training earlier.
She must have forgotten about the anal training kit because of the alcohol. So I slammed my cock into her plump ass again with heavy thuds, as if telling her not to worry.
She seemed to be biting the pillow now; her moans had almost disappeared.
"Oh, you get tighter when I touch your back hole?"
I smiled in satisfaction and continued ravaging her pussy. Truly, the more I lightly scraped the wrinkles with my fingernail, the stronger the squeeze became.
Would it get even tighter if I put a finger in? How good would it feel to put my cock in the back?
It seemed Subin had talent for anal. I'd learned that the women of this world basically felt pleasure from their asses, but seeing it in person was fascinating.
After pounding her like that for a long while, I felt the cum rising.
I was about to blow, and the head of my cock swelled plump and full.
"Hah, hah, hah!"
Subin also didn't know what to do, repeatedly grabbing and releasing the bed. It was clearly the orgasm right before climax.
The ticklish sensation from my thighs all the way to the tip of my urethra grew stronger, and then tremendous pleasure surged in.
"I'm cumming inside!"
I said that and, without even asking her permission, ejaculated straight into her womb.
A thrilling ecstasy like electricity racing down my spine washed over me.
—Bwooosh, bwururururt! Spurt, spurt!
While cumming I kept grinding my now extremely sensitive cockhead against the inside of her pussy. I shook it so hard the head felt hot.
Then I came once, twice, three times with heavy pulses. An enormous amount of semen poured into her vagina.
"Euuung…! Euh, euh, euhng♡"
Climaxing together with me, Subin trembled and sobbed.
I kept her head pressed down while still buried inside her, and the strength gradually left her pussy.
"Huh? Subin?"
I called out in confusion and smacked her ass with my palm once.
—Slap!
But her ass only jiggled springily with no other reaction.
Thinking Subin had fainted, I felt a little sorry, wondering if I'd been too rough.
I'd only gone a bit harder than usual. Maybe the alcohol tonight had left her with less stamina.
In that case, should I let her rest thoroughly and then wake her up for anal training later?
While mulling over those thoughts I turned her body forward so she could breathe more easily, and then….

"…Huh?"
There was the face of Aunt Danbi—Subin's mother—passed out with her expression completely wrecked by orgasm.
