Haruki had been living with them for more than two weeks now.
As usual, his wife Satomi rushed out early with her father, both too busy with work to linger around the house. This left Haruki alone with Kyouko once again.
That morning, after Satomi had already left, Haruki was just waking up.
"Yaaawwn…"
He stretched lazily before heading to the bathroom to wash his face. He hadn't managed to do his morning exercises for the past two weeks—something about working out on the lawn felt weird. Awkward, even. He wasn't sure why.
Making his way downstairs, he headed straight to the kitchen and poured himself a glass of water.
"Hmm? Where's Kyouko-san?"
He glanced around, expecting to see her, but the house was silent. After finishing his drink, he was about to head back upstairs when something caught his attention. The back door stood open. A gentle morning breeze drifted in, carrying the scent of flowers and fresh grass.
Curious, Haruki walked toward the door and peeked outside.
And there she was.
Kyouko.
She stood in the middle of the backyard, stretching her arms above her head. The morning sunlight caught her toned, flawless skin. She wasn't wearing regular workout clothes—her form-fitting sports bra hugged her perfectly, and her leggings accentuated every curve of her hips and thighs.
Haruki swallowed hard.
His mother-in-law… looked absolutely breathtaking.
She transitioned into a slow stretch, bending forward slightly. Her hair, tied in a loose ponytail, swayed with each movement. She was completely unaware that someone was watching.
Haruki knew he should look away.
But it was impossible.
Looking at his beautiful, youthful mother-in-law—who didn't have a single wrinkle, whose skin and face looked decades younger than they should—with that kind of body...
He stood frozen by the door, gripping the frame.
"She seriously doesn't look her age at all."
Her stomach was flat, her skin unbelievably smooth. No sagging, no wrinkles—nothing that showed any signs of aging. If anything, she looked better than most women half her age.
He couldn't help but admire her beauty, the effortless way her body moved.
Then Kyouko noticed him.
She smiled.
"Haruki-kun?"
Haruki's heart stopped.
"A-ah... y-yes, Kyouko-san?"
She tilted her head slightly, her smile widening.
"Wanna join me?"
Haruki's brain went blank for a moment.
"Ah… uh… sure… I-I'll just change into my workout clothes first."
"Okay~" Kyouko replied, stretching her arms again before continuing her routine.
Haruki turned and rushed upstairs, trying to shake off the wild thoughts flooding his head.
Who in their right mind would let a chance like this slip away? Exercising with a sexy, beautiful girl like Kyouko—it was almost too good to be true.
Haruki came back downstairs dressed in only a pair of workout shorts, his upper body completely bare.
Kyouko, who had been waiting for him, widened her eyes slightly in surprise.
"Oh...my..." she murmured, momentarily stunned.
Haruki's body was lean and toned, his muscles well-defined—not overly bulky but sculpted in a way that made him look like he belonged in a fitness magazine. His chest, arms, and abs looked carved from stone, and when he stretched his arms over his head, the movement made his muscles flex subtly.
Kyouko quickly looked away, clearing her throat.
Why does he have to look like that?
A model's body—muscular but not too bulky. Perfect.
Exactly her type.
There was a brief silence between them before Kyouko smiled and gestured toward the mat.
"Let's start with some stretches first, Haruki-kun."
Haruki nodded, stepping forward as she demonstrated.
They began their routine with simple stretches. Kyouko bent forward, reaching for her toes, her fitted workout clothes following every contour of her body. Haruki's eyes lingered on how the leggings traced the lines of her legs, her toned thighs, and the curve of her hips as she stretched.
"Alright, let's do sit-ups next," Kyouko said cheerfully, completely oblivious to his stare.
Haruki swallowed hard as she lay on the mat, knees bent, feet flat on the ground. He moved into position, kneeling down and placing his hands lightly on her ankles to keep her steady.
Kyouko lifted her torso, her stomach muscles flexing subtly. Her breasts, barely contained by her snug sports bra, rose with each sit-up.
Haruki tried to look away, but every time she came up, he caught a glimpse of her cleavage, her chest bouncing with each movement. The sight was mesmerizing.
How could I not look?
"One… two… three…" Kyouko counted softly, completely oblivious to the effect she was having on him.
Haruki, on the other hand, was struggling.
This is bad.
Next, they switched.
Haruki lay on his back while Kyouko moved to hold his legs in place. From his position, he had a clear view of her leaning forward, her breasts pressing slightly against her forearms as she braced herself.
Each time he sat up, he got closer to her face—closer to her lips.
"You're good at this, Haruki-kun," Kyouko commented, smiling.
"T-thanks…"
They continued their workout, moving from one exercise to another. Kyouko, unaware of how sensual every movement appeared from Haruki's perspective, was simply enjoying the exercise.
Meanwhile, Haruki was experiencing an entirely different struggle, one that had nothing to do with physical endurance.
After finishing their sit-ups, Kyouko stood up, stretching her arms above her head.
"Alright, let's move on to..."
But just as she took a step back, her foot caught on the edge of the exercise mat.
"Ah—!"
Kyouko lost her balance, pitching forward.
Haruki, who was still sitting up from their last exercise, instinctively reached out to catch her. But his grip slipped, and they both tumbled down onto the mat.
Before he could react, Kyouko landed right on top of him.
Soft. Warm.
Her breasts pressed against his bare chest, sending a jolt through his entire body.
Their faces were inches apart, their lips nearly touching. Haruki felt the faint, warm brush of her breath against his mouth. She smelled sweet and light—something uniquely feminine.
For a moment, neither of them moved.
Haruki froze. His hands had instinctively grabbed her waist, the heat of her body radiating through her thin workout top.
Kyouko's eyes widened, her lips parting slightly in shock.
Silence.
His heart pounded in his ears. His mind screamed at him to look away, to do something—anything—but all he could do was stare.
"S-sorry!" Kyouko stammered, quickly pushing herself up, her cheeks flushing.
"N-no, it's fine," Haruki muttered, pulse racing.
Kyouko sat back, brushing a strand of hair behind her ear.
"S-sorry… again."
Haruki exhaled slowly, forcing himself to relax.
"Don't worry about it, Kyouko-san."
Kyouko stood quickly, brushing off her leggings and forcing a small smile.
"I think we should stop for today," she said, trying to sound casual.
Haruki sat up, still feeling the lingering warmth where her body had pressed against his. He nodded.
"Yeah…."
She turned away slightly, tucking a loose strand of hair behind her ear. She was trying hard to hide how flustered she felt, but Haruki could see the faint pink blush on her cheeks.
"A-Anyway, Haruki-kun… that was a good workout. Let's do it again tomorrow." She smiled, though there was a hint of nervousness in her voice.
Haruki exhaled, forcing himself to focus.
"Okay, Kyouko-san."
As she walked back inside, Haruki's eyes lingered on her for a moment before he ran a hand through his hair.
