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

Ah, when you stimulate me like this, an erection comes so easily...

Due to Ayaka's deliberate provocation, my penis had grown enormously, arching back and pressing against my stomach. It felt almost offensive.

"Yes, let's try a little harder," Ayaka said quietly.

As she spoke, she began to stroke my back and waist with one hand, probably to check the tension in my muscles.

When her hand reached my stomach, it brushed lightly against my cock. She suddenly pulled her hand away, so she must have noticed the state I was in.

She didn't touch me again, but the way she checked my muscles changed - it almost felt like she was caressing me.

"Okay, now let's try a slightly different type of forward bend. I'll show you how," she instructed.

With that, Ayaka stood in front of me with her back turned and her legs shoulder width apart. She bent forward and demonstrated the posture.

I was stunned. Ayaka's ass and pussy were right in front of me. She put her hand between her legs, extended it to me and said:

"Please pull my hand."

She looked at me with a playful smile from between her legs. It felt like she was provoking me in a very innocent but deliberate way. There was no doubt that Ayaka was intentionally getting unusually close to me during the stretches.

I couldn't stop thinking - I wanted to bury my face in her pussy... I wanted to grab her soft ass and squeeze it with all my might... No, what if I just pulled down her spats and fuck her from behind?

My sexual desire was at its limit, ready to explode. If anything could trigger it, it would be the breaking point.

What would happen if I buried my face in her pussy right now? No, that's too much. I need to come up with a more subtle plan, something more realistic.

Just a little... Just a little touch... Even if it's just brushing the tip of my nose against her and pretending it was an accident...

I was so close to giving myself the green light to carry out this plan.

--Ahh, what are you doing? Stop it!

Would this be the end of my relationship with Ayaka? Or would she treat it as an accident?

My rationality clashed violently within me... but in the end, my better judgment won out. I did nothing.

Ayaka straightened up and returned to her upright position.

"Do you understand?" she asked.

"I understand, but... I'm exhausted. Please stop," I replied, barely holding myself together.

If this continued, I might actually attack her.

Ayaka-san looked at my sister and seemed to get a sign that said, "Why don't you just let it go for now?"

"Well then, should I stop here...?"

She said sadly and let me go. As I lay there trying to catch my breath, the two of us started talking. Then my sister said to me,

"Kei-chan, we're going to go for a quick run for about an hour to finish up. If you want, why don't you come with us?"

I shook my head.

"No way, no way, you have so much stamina..."

Frankly, I'm amazed at the monstrous energy of these two.

"Then please stay home..."

She seemed a little embarrassed to run outside in her yoga clothes, so she changed into her regular running clothes in my sister's room.

"Ayaka-senpai, please hang up your sweaty bra and leggings over here..."

In my house, there is an indoor drying room right next to the washing machine on the first floor. Apparently, she and my sister wanted to hang the sweaty clothes there for a while.

Something inappropriate is secretly being planned inside me.

"Well, I'll be off then."

With that, the two of them left. I immediately got up and quickly went to the drying room.

My sister and Ayaka's sports bras and leggings were hanging there. I approached Ayaka's and pressed my face against them, enjoying the smell of her sweat.

...Ah, Ayaka-san's smell... I can't stand it...

I felt like I could understand the feelings of underwear thieves all too well. But in a way, I feel sorry for them. Because the underwear they steal has already been washed. But these are brand new, just taken off.

I pulled Ayaka's sports bra over my head, tied it around my neck, grabbed her leggings, and ran to the bathroom. I locked the door from the inside and quickly took off my sweatpants and underwear.

Then I pulled Ayaka's leggings over my head, inhaled and exhaled several times, enjoying the scent, and then began to stroke my cock...
