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, Satomi had already left, and Haruki was just waking up.
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. Maybe awkward. He wasn't sure.
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 return upstairs when he noticed something—the back door was open. A gentle morning breeze drifted in, carrying the scent of flowers and fresh grass.
Curious, Haruki walked toward the door and peeked outside.
She stood in the middle of the backyard, stretching her arms above her head. The morning sunlight highlighted her toned, flawless skin. She wasn't just 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 damn... it was impossible.
He stood frozen by the door, gripping the frame.
"Damn... 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 and the way her body moved effortlessly.
Then Kyouko noticed him.
"A-ah... y-yes, Kyouko-san?"
She tilted her head slightly, still smiling.
Haruki's brain short-circuited 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 around and rushed upstairs, trying to shake off the wild thoughts in his head.
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..." 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 such a body?
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 tight-fitting outfit hugging every curve of her body. Haruki couldn't help but stare at how the leggings outlined her legs, her toned thighs, and the perfect shape of her ass as she stretched.
"Alright, let's do sit-ups next," Kyouko said cheerfully, completely unaware of Haruki's gaze.
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 breast, 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 breast bouncing with each movement. The sight was mesmerizing.
"One... two... three..." Kyouko counted softly, completely oblivious to the effect she was having on him.
Haruki, on the other hand, was struggling.
Haruki lay on his back while Kyouko moved to hold his legs in place. From his position, he had a clear view of her body 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.
They continued their workout, moving from one exercise to another. Kyouko, unaware of just 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.
Kyouko lost her balance, tipping forward.
Haruki, who was still sitting up from their last exercise, instinctively reached out to catch her. But his grip slipped, and both of them tumbled down onto the mat.
Before he could react, Kyouko landed right on top of him.
Her full, round breasts pressed against his bare chest, sending a shockwave through his entire body.
Their faces were too close, their lips nearly touching. Haruki could feel the faint, warm brush of her breath against his mouth. She smelled sweet—light, and something uniquely feminine.
For a moment, neither of them moved.
Haruki froze. His hands had instinctively grabbed her waist, feeling the heat of her body through her thin workout top.
Kyouko's eyes widened, her lips parting slightly in shock.
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 face flushing slightly.
"N-no, it's fine," Haruki muttered, his heart racing.
Kyouko sat back, brushing a strand of hair behind her ear.
"S-sorry... again." She avoided his gaze, clearly flustered.
Haruki exhaled slowly, forcing himself to relax.
"Don't worry about it, Kyouko-san."
Kyouko stood up quickly, brushing off her leggings and forcing a small smile.
"I think it's better if we stop exercising 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.
Kyouko turned away slightly, tucking a loose strand of hair behind her ear. She was trying hard to hide her flustered expression, but Haruki could see the faint pink blush on her cheeks.
"A-Anyway, Haruki-kun... today was a good workout. Let's do it again tomorrow." She smiled, though there was a tiny hint of nervousness in her voice.
Haruki exhaled, forcing himself to focus.
As she walked back inside, Haruki's eyes lingered on her for a moment before he ran a hand through his hair.
