Busty Boss Titjob in Onsen Bath During Company Trip
Late summer night at a rural company onsen trip. After drinking, a man encounters his strict 40-year-old busty boss alone in the steamy bath near closing time.

Late on a summer night approaching the end of summer, at a small company trip destination in a rural city, I was enveloped in the steam of the large public bath. The onsen ryokan in the mountains a little away from the company was nearly chartered for the planning department's employee trip. Because I had drunk quite a bit at the afternoon banquet, I headed to the large bath past 10 PM. It was nearly 11 PM at night, the bath was already quiet, and it seemed close to closing time. Unlike the private baths at the ryokan, the large bath was spacious, with two rock-built tubs filled with thick mist.
I wrapped a towel around my waist and stepped out of the changing area into the bath. The stone floor underfoot was slightly hot, and the steam blurred my vision. The water in the tub exceeded 38 degrees, warming my body to the core even on a summer night. The alcohol lingered, making my head feel heavy. Wanting to cool my heated body, I poured water over myself and was about to sink into the tub when I noticed a figure moving on the rock ledge across from me.
"Koji...?"
It was a low but familiar voice. Ayano. The planning department head, usually strict with subordinates and mercilessly scolding over even a single mistake in documents. Her long black hair was tied up, and she had removed her traditional yukata, pressing a single towel against her body. The dim night lighting made her look more seductive than usual. Approaching 40, her ample breasts threatened to spill from the towel. The word "busty" crossed my mind. I quickly bowed my head.
"Ayano-san... I'm sorry to disturb you at this hour."
"Oh, couldn't sleep because of the drinks? Same here."
Her voice carried a hint of intoxication. She leaned against the edge of the tub, soaking her feet in the water. Her gaze swept over my body for a moment. I sank into the opposite side of the tub, submerging myself in the hot water. The heat made me catch my breath. The steam on this summer night was sweet, with a faint scent of sulfur.
At first, there was silence. Though there was distance between us in the tub, she slowly moved closer. Ripples formed, and the heat of the water stimulated my skin. What should have been a chance encounter seemed to carry a slight heat in her eyes. In the planning department's daily routine, she always wore suits, rarely choosing clothes that emphasized her chest line. But now, whenever the towel shifted, I caught glimpses of her pale, soft skin and the deep cleavage between her large, round breasts.
"Koji, you've been working hard on the recent presentations. You have more grit than I expected."
"Thank you... It's thanks to you, Ayano-san."
The conversation began with work topics. She smiled unusually while soaking in the water. Perhaps due to the alcohol, her voice sounded slightly sweet. In the tub, her foot accidentally brushed against mine. A hot sensation ran through me. She pulled away quickly, but the silence that followed lingered a bit longer.
"This feels quite nice. It's rare to have such a large bath on a company trip, isn't it?"
Ayano sat up, lightly pressing her chest. The wet towel clung to her skin, clearly outlining the shape of her breasts. The contours of her ample bust swayed beyond the steam, entering my view. I tried to look away, but the alcohol made my gaze unsteady. Noticing this, she drew a little closer.
As the distance closed, the heat of the water and the intoxication eroded our usual boundaries. Her shoulder touched my arm. It was soft and warm. Her scent, a mix of body heat and soap, sweetly tickled my nose. I could hear her breathing nearby. My heartbeat grew louder.
"Koji, isn't it a bit hot? Sink in deeper."
As she spoke, she placed her hand on my shoulder. Her fingers felt hot. My mind knew I should avoid this. The subordinate-boss relationship. The forbidden line. Yet her eyes fixed steadily on me. The mature allure of an adult woman slowly approached through the summer night's bathwater. Her cleavage swayed with the ripples, drawing my gaze.
Gradually, I found myself immersed in her body heat and the water's warmth. As the contact continued, her fingers traced my chest. The lingering scent of sweet perfume mingled with the steam. All I could hear was the sound of the water and her breath. A parched sensation spread through my throat, as if through taste. Thus, the night slowly tilted toward sensuality.
