Mom's Lesson Time! And Mom's Reward!

I wondered what else she was going to teach me…

Ayoung, who had been sitting, suddenly lay down on the bed.

“…Would you like to sit on Mommy’s face♥?”

Did she even realize what it meant to sit on her face?

I thought we had already crossed the line, but this felt like crossing a strangely different one, stirring up a bizarre, lewd sensation inside me.

A sense of depravity different from the time I had pissed into her mouth and ass.

Even as I hesitated, I was already standing over Mom’s face.

I slowly bent my knees, bringing my ass closer to her face.

When I had rubbed my cock against her it had turned me on, but it hadn’t felt this twisted.

I aimed my asshole directly at Mom’s lips and sat down.

“Like this… Ayoung?”

“Mm… yes♥….”

Ayoung answered and immediately began licking my ass with her tongue.

The tip of her tongue flicked and lapped around my asshole—wet, slippery, yet warm. The sensation was grotesque.

It was hard to believe that Mom’s tongue was actually tracing the sensitive skin around my anus. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠ This was the same gentle, beautiful mother who had always felt so far removed from anything vulgar, yet here she was, her pure and elegant face shamelessly licking my filthy asshole.

“Mmm… mmm… chup♥… slurp slurp… chuup♥… chu♥!… hrrruuup♥!”

“You like my asshole that much?”

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠“Mmm♥♡… And I want to smell your cock at the same time♥♡…”

At Mom’s request, I turned around, repositioned myself so my asshole was aimed at her mouth again, and sat back down on her face.

The difference this time was that my balls were planted squarely in the center of her nose, covering almost her entire face.

My cock lay across her forehead and dangled down to the floor.

“Sluuuuurp♡…! Haa…! It’s so good♡…! Master’s thick, heavy cock scent…♥! This thick, nasty, days-old male stench…♥!”

She buried her nose into my massive, heavy balls—slick and sticky from various fluids and pheromones—and greedily inhaled the smell.

“Sluuuuurp♥!! Haa!! Chuuuup! Chulup♥! Chooooook♥! Sluuuuurp! Haa! Chup♥… chup♥…”

“Ugh! You filthy bitch… my balls are tickling from your breathing..!”

“I can’t help it when it smells this strong…! Chooooop♥…! Chooooop♥! Sluuuuurp! Haaah♥!”

Psh♥! Psh♥! Pshuuuuuuu♥!

Mom, who had been sucking and sniffing my asshole, finally stuck her tongue out as far as it would go, rolled her eyes back, and made a completely stupid ahegao face.

“Stop making that dumb face and suck properly!”

With that vulgar expression and her tongue hanging out, Mom stretched it even longer and began shoving it straight into my asshole.

“Beeeeh♥…. wriggle wriggle♥…. eueueueueuup♥eup♥reru♥reru♥rero♥rero♥rero♥rero♥!”

Mom’s tongue burrowed deep into my asshole and began wildly scraping the insides, stimulating my prostate.

“Khh… Ayoung, use your hands… jerk me off too!”

“Rero♥rero♥rero♥rero♥… choooooop♥♥!”

Slap slap slap slap slap!

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Because the position was awkward and my cock was so thick, she started using both hands to stroke me rapidly.

Even so, her vulgar tongue never stopped stirring and sucking inside my asshole.

The constant stimulation to my prostate made me feel the urge to cum even though she had barely touched my shaft.

Mom pushed her tongue in to the root, then pulled it out to its maximum length before plunging it deep inside my ass again.

“Khh… getting my asshole cleaned so thoroughly..! Uoooh…! I’m cumming… I’m cumming while Mom licks my asshole aaaah!”

The climax surged through me. I grabbed Mom’s hair, yanked her head upward, positioned her mouth right at my cock, and slammed it straight in.

“Don’t spill a single drop! How dare you torment your Master’s asshole like that!”

“Hngh♥!? Ubuub♥! Ubup♥♥! Uup♥! Up♥!”

Glurk glurk glurk glurk glurk!

I came with the force of trying to fill her stomach with semen.

Gulp♥! Gulp♥! Gulp♥!

Her throat moved rapidly as she tried to swallow, but she couldn’t keep up with the speed of my ejaculation.

Before long, she couldn’t swallow anymore and semen began overflowing from her mouth.

I hurriedly wiped away the cum so it wouldn’t drip onto her clothes or hair.

“Don’t swallow it all… it’s Master’s order… you can keep holding the semen in your mouth, right…?”

Squelch♥!

I finished ejaculating and pulled my cock out of her mouth.

Nod nod♥!

“So you’ll keep holding it in your mouth until I tell you it’s okay to swallow?”

“And the semen and piss in your lower holes too… you can keep those, right…?”

“U… uum…♥”

“Good girl. Thank you, Ayoung! If you do that for me, I’ll be really happy!”

With a heart full of gratitude, I gently stroked her face with my cock.

Mom’s face flushed with pleasure at the feel and scent of my dick.

When I pressed lightly on her swollen cheeks with my shaft, semen squirted out between her lips with wet spurts.

‘I shouldn’t waste any more cum by pressing like that.’

Mom seemed to have reached her physical limit, and I was getting sleepy too.

Her body was already almost completely filled with my semen, so there was no room ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠for more.

“Let’s end today’s lesson here. Sleep well, Ayoung!”

“Uum…♥”

She picked up her clothes, now completely soaked and stained with semen, and put them on. Strangely, it didn’t look that obvious.

Her mouth was stuffed full of cum, on the verge of bursting. Her clothes were soaked and see-through, and her body was covered in the marks of our mating.

---

Mom waddled away unsteadily, her ass swaying because of the liquid sloshing inside it.

She kept having to cover her mouth to stop the cum from leaking out as she moved with difficulty.

Semen continued to drip down her thighs from both her asshole and pussy as she left the room with that incredibly lewd view from behind.

Once she was gone, the smell of her pussy juices and semen in the room lessened a bit.

“Oh. There’s still a condom inside her pussy.”

[Analysis of ‘Park Ayoung’ has been completed.]

The moment I remembered that I hadn’t removed the condom yet, the analysis finished.

“I’ll just take it out later.”

================================================================

I have no idea why these insane achievements that permanently lower intelligence keep appearing.

The Smell Fetish one is hot, but I have no intention of turning Mom into a drooling idiot and fucking her, so I’ll turn it **OFF**.

Of course, I’ll keep Yuna’s **ON**.

Even without the Smell Fetish effect, Mom already loved the scent of my cock enough.

Face Rubbing… I don’t want my mom getting rubbed on and fucked by other men, so that one’s **OFF** too.

While I’m at it, I’ll turn Yuna’s off as well.

It’s a relief she hasn’t been taken by any other man yet.

The way she wore that hoodie pulled low over her face recently—whether it was because of me or because of this achievement—she had been pretty defensive.

Asphyxiation Resistance… that one seems like a pretty good achievement. Just thinking about enjoying longer and harder breath-play sessions in the future is already making my cock throb.
