I can't get enough of this mom's ass in tight pants.

Kei-san sucks on my nipples. A tingling sensation goes through my head.

...Ahh, this feeling... it's been a while...

He passionately sucks on my nipples and kneads my breasts so hard that it hurts.

...Kei-san's virginity is mine... Ufufu... Ufufu...

"Kei-san, don't you want to see a woman's vagina?"

"Huh?"

He looks surprised.

I stood up, showed Kei-san my back, and slowly pulled down my low-slung pants.

Behind me, Kei-san swallowed his spit.

What do you think? My ass and black thong... Isn't it nice?

After taking my tight pants off around my ankles, I was left naked in just a thong. I sat down on the sofa, got up on my knees and smiled at Kei-san.

Kei impatiently pushed the low table aside and knelt in front of me.

"You can lift up my thong."

He stared at my vagina. I spread my legs a little and made an M-legged pose on my knees.

Kei-san's hands moved... slowly lifting the thong covering my vagina. He showed a surprised look. It must have been the first time he saw a woman's vagina.

"Ah, Ayaka-san, can I lick here, here?"

"That's fine... just be gentle and love me..."

He grabbed my thighs and brought his face close to my vagina. And then... Kei's tongue touched my labia.

"Ahhh..."

Just like a dog, he licked the fountain of fluid that flowed from my pussy, one after the other, and waves of pleasure washed over me.

...What a pleasant cunnilingus...

After basking in the pleasure for a while, I pointed to a spot on my vagina. A small protrusion above my labia... my clitoris.

"Lick here."

Kei-san began to lick that spot with great enthusiasm. Suddenly, a doubled amount of pleasure shot through my brain.

"Ahh, ahh, ahh..."

The waves of pleasure turned into rough waves. While I was enjoying it, Kei said shyly,

"Ayaka-san, could you please grant me a request?"

"Sure. What is it?"

"I love Ayaka's ass. If you don't mind... I'd like to see it from behind. Licking and breathing... Can I do it?"

"From behind... okay."

I stood up and turned my backside to Kei, still wearing my thong.

"Ah, Ayaka-san, just stay like that for a bit."

Then suddenly Kei-san came from behind and pressed his face hard into the crack of my ass, breathing heavily.

You enjoy my ass.

"How do I smell?"

I asked Kei.

"I can't stand it. Please let me do this a little longer."

Saying that, Kei grabbed my thighs with both hands and buried his face deeper into my ass.

Waka-chan said that Kei-san used to bury his face in his mother's ass when he was little. So he really loves butts....

After a while, I felt both hands leave my thighs.

"Kei-san, what do you want to do? Would you like to lick my pussy from behind?"

"Yes, please."

"Now please let me take off your thong."

My bottom was still facing Kei.

Kei-san grabbed both ends of my thong and carefully pulled it down. When it reached my knees, I took it off around my ankles.

Then I placed both my knees on the sofa seat and leaned against the backrest. This put me in a doggy-style position, so my butt was completely visible to Kei-san.

It's extremely embarrassing to like this in front of a man, but since it's Kei-san, I want him to be even more aroused by my butt.

I hear a swallow from behind me. He kneels down in front of my bottom and begins to touch it lightly.

"How is my ass?" I ask.

"It was my dream to touch it," he says.

Saying that, he suddenly presses his face into the crack of my ass and runs his tongue over my labia minora.

"Ahhh..."

My face turns back involuntarily.

Kei licks the entire labia evenly, poking my clit with the tip of his tongue, licking and rolling it around, making me moan.

"Ah, ah, ah..."

I'm already wet and ready to continue... Next, I have to prepare Kei.

"Kei-san, it's about time."

I grab Kei's hair behind his head and pull his face away from my crotch. His eyes are dazed, unable to focus.

"Kei-san, try to stand there for a moment."

He stands up obediently. I take off Kei's pants and pull them down around his ankles. The front of his briefs is so tented it looks like it might burst.

I knelt in front of Kei and pulled down his panties, revealing his erection, which was stiff and powerful.

Wow... It might even be bigger than Natsuki's... Just the thought of him entering my body sent a vortex of anticipation and nervousness through me.

I let a generous amount of saliva drip onto it - one drop, two drops, three drops - then turned my hand to spread it evenly.

"Ahh, it feels good..." Kei murmured.

I began to stroke him gently.

"Ahh, that's good, that's really good."

I could feel him becoming more and more energetic in my hands.

As expected, 21 year old men have a different kind of energy.

Just as I was thinking about stopping at the right moment and teasing him a little more, Kei suddenly screamed:

"Oh, Ayaka-san! I'm coming!"

Kei screamed, and the white liquid came out with incredible force, hitting my face. It sprayed from my forehead to my eyes, nose and mouth.

I just closed my eyes and let the white liquid cover my face.

"I'm sorry, Ayaka... I just couldn't stop myself."

"It's okay. I'm fine," I reassured him with a small laugh.

"But I didn't expect you to come on my face."

I thought I might have exaggerated a bit, but I couldn't help but giggle slightly.

...Okay, next is finally...
