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

Across the table at the family restaurant, Ayaka smiled at me and said:

"If you don't mind... I'll help you with the housework."

Eh, housework? No way...

I was unsure how to respond to her sudden offer. After all, Ayaka-san is a married woman.

If she comes to my house... um... uh... something might go wrong.

However, it's rare to meet such a beautiful older woman...

I couldn't help but hope - just a little - that something might happen with Ayaka.

No, no, that's not possible at all.

If I were alone with Ayaka at home, there was a hundred million percent chance that I would lose control and attack her.

The fear of that possibility was overwhelming.

I could barely think of a suitable answer.

"Uh, well, I guess that's okay, but... I'll have to discuss it with my sister first."

Ayaka smiled warmly.

"Okay."

After that, we chatted for a while, exchanging contact information and deciding to stay in touch. At one point, Ayaka seemed lost in thought, and even when she lowered her head slightly, the sadness in her expression was breathtaking.

When I got to college, I called my sister shortly after I arrived.

"How was Ayaka-senpai?"

My sister's question came immediately, as if she had been waiting for the call.

"Ayaka-san said she would like to help with the housework..."

"Oh? Then why not let her? It sounds like a good idea."

"But Ayaka-san is married..."

"What are you talking about? Oh, I just got another call. I'll call you back later."

"Okay."

A short time later, my sister called back, but I was in the middle of a lecture and couldn't answer. Afterwards, I called her back.

Before I could say anything, she suddenly asked:

"Kei-chan, will you be home next Saturday?"

"I think so... Why?"

"I'm bringing Ayaka-senpai over. So please stay home."

"Wait, what? You're bringing Ayaka-san here? Why?"

"It's okay, don't worry about it. Just wait for us, okay?"

It was unusual for my sister to be so insistent. There must be something going on.

---

On Saturday morning, they arrived at the house.

"Good morning, Kei-chan."

"Good morning."

"Senpai, please come in."

"Oh, Waka-chan, this is such a nice house."

My sister pushed me aside and went upstairs with Ayaka. They entered the living room and started talking in hushed tones.

"Senpai, what do you think of this room?"

"It's okay. It's fine..."

What's fine? What are they planning?

Just as I was thinking, my sister came over to me.

"Hey, I'm going to change in my room. Don't peek, okay?"

She disappeared into her old bedroom upstairs.

Changing clothes? What are they up to?

Moments later, both Ayaka and my sister came out of the room. I was shocked to see them enter the living room dressed in yoga clothes.

Ayaka was wearing only a sports bra on top and short leggings on the bottom, both of which clung to her body and accentuated her figure.

It felt like an intentional provocation.

I was startled to realize that Ayaka's chest was much larger than I'd assumed. At the crosswalk, they didn't seem so prominent.

So this is what they call 'hidden assets.' The female body is truly a mystery.

But most of all, Ayaka's short leggings... they hugged her shapely, peach-like buttocks perfectly. I couldn't help but be jealous of those leggings.

I tried to stop staring, but I didn't know where to look. My sister pulled me out of my thoughts.

"Come on Kei-chan, let's do it together."

"What?"

"Yoga, of course. Hurry up and get changed - sweatpants will do."

The living room was long and narrow, with the sofa pushed aside to make room. I ended up behind the two women.

They began to move to a yoga video playing on a laptop. From my position, their figures were right in front of me.

"Lift your hips more...one, two, one, two..."

They got down on all fours, lowered their heads, and repeatedly lifted their hips high into the air. The poses were far too suggestive.

This is bad. I felt a certain reaction building up.

I desperately tried to control myself, but my movements became stiff and awkward.

"Kei-chan, move your body more!"

My sister's instructions came sharply, leaving me no choice but to continue.

This is really bad.

The two women continued their routine, sweat glistening on their bodies. The faint, musky scent in the air made it difficult to concentrate.

Then they lay on their backs and spread their legs wide. That's when I noticed a damp spot forming on the crotch of Ayaka-san's leggings.

Ayaka-san's sweat... I couldn't help but bury my face there and take a deep breath.

Just then, my sister spoke to Ayaka.

"Ayaka-senpai, can you help my younger brother stretch? He seems to be very stiff."

"All right, I'll help."

Ayaka came over to me.

"Let's start with some stretching," she said.

I sat down and she made me spread my legs wide and lean forward.

"Okay, take a deep breath. Exhale as you lean forward."

She stood behind me and gently pushed down on my back to help me stretch.

I was painfully aware of how stiff I'd become from lack of exercise.

"Ugh, I can't go any further..." I groaned.

"This won't do," Ayaka said, pressing her body against my back to apply more pressure.

This is bad.

The feeling of her soft breasts pressing against my back, combined with the smell of her sweat, made it impossible to control myself.

I looked at my sister, silently begging for help, but she pretended not to notice. The two of them were clearly in this together.

What are they going to do to me?

Ayaka wrapped her arms around me from behind, her face so close that I could feel her breath on my cheek.

The reaction in my crotch was impossible to hide at this point. I felt completely exposed.

"Ufufu... cute," Ayaka whispered.
