Busty Female Doctor Fingers Him to Climax in Private Hot Spring Bath

It was a sudden bright afternoon between rainy season showers. Chasing sales quotas and working overtime every day, I impulsively booked a nearby hot spring hotel. The time slot was early afternoon. After checking in, I decided to use the private bath first. Even though it was summer, the rainy season brought heavy humidity that clung to the skin, and that muggy warmth lingered in the lobby as well.

The hallway to the large bath was quiet and smelled of wood. The private bath, named "Rabbit Flower Room," was a standalone open-air bath suite that happened to be available without a reservation. I changed into a towel in the changing area, slid open the door, and warm steam billowed out. The stone floor felt warm, and the tub was about three meters across. Several large rocks sat inside the water, with a gentle flow pouring from the spout. Outside, trees surrounded the area, and pale light from the break in the clouds reflected on the water's surface.

I sank into the tub alone at first. My body gradually adjusted to the hot water. Enjoying the slow release of tension in my shoulders, I closed my eyes. Then I sensed the door sliding open without a sound. Someone had entered. I looked up to see a female doctor who had removed her white coat. I would learn her name later, but at that moment I did not know it.

She appeared to be in her mid-thirties. Her black hair was tied back, and her full breasts pushed against the front of her yukata. She was slightly shorter than me, and the curves from her shoulders to her chest stood out clearly through the steam. I wondered if she was a guest or a hotel staff member, but my first impression was of a composed, mature woman. Noticing my gaze, she smiled a little apologetically.

"It looks like our reservations overlapped. If you like, you can use this tub too…"

Her voice was low and easy to hear. Pressing a finger to her chest, she sat at the edge of the tub. The water rippled gently. I quickly sat up and put a little distance between us. She remained unfazed, sinking up to her shoulders in the water.

"I usually work at a hospital, but today is my day off. It seems we happened to book the same time… If I'm not bothering you, would you mind if I join you?"

The conversation began naturally. She spoke about medical work, and I lightly mentioned the stress of sales. As we talked, the heat and humidity of the water warmed my body. Every time her breasts swayed in the water, the surface rippled noticeably. Her pale skin took on a faint flush from the steam, and sweat glistened on her neck.

A few minutes later she suddenly stood up. Moving behind me, she picked up a sponge.

"Shall I wash your back? Since we're here."

Before I could refuse, her fingers touched my back. The sensation was soft. It was not the sponge; her palm was directly on my skin. Her hot fingertips slid between my shoulder blades and up to my neck. Every touch made my skin tingle. She drew closer, pressing her full breasts against my back. The soft, heavy feeling made the position of her nipples faintly perceptible.

As I sat up in the water, she whispered in my ear.

"You're tense. Relax more."

Her voice was sweet yet somehow businesslike. Her fingers moved from my back to my waist, then to my buttocks, stimulating slowly and carefully with the pads of her fingers. While the muscles in my lower back loosened, I could no longer control my lower body. She slid one hand along my inner thigh, approaching my groin. My erection was now obvious even in the water.

"This area tends to get stiff, doesn't it?"

Speaking calmly, she lightly stroked the head with her fingers. In the hot water the contrast with her cooler fingertips was striking. Grip, release, stroke—the motions continued relentlessly, and my breathing grew ragged. Her large breasts remained pressed to my back, the weight and softness transmitting through my entire body. The scent of sweet soap mixed with the sulfur smell of the water and stung my nose.

She intensified her approach. One hand squeezed the head while the other gently kneaded my scrotum. Her finger movements were precise, stimulating the right nerves as if performing an examination. My hips rose involuntarily, splashing water. Smiling, she whispered.

"Just a little longer."

Her voice echoed in my ear. Her fingers traveled slowly from base to tip and back again, over and over. The swollen shaft threatened to slip from her grasp. She pushed it back and squeezed tightly once more. Breathing became difficult; heat built at the back of my head. All my senses seemed focused on her hands. My vision blurred from steam and rippling water, but her breathing remained clear.

The pads of her fingers rubbed the slit repeatedly. The slick sensation mixed with precum dissolved into the water. She increased pressure and speed. Grip strength, stroking pace, finger rotation—every calculated motion severed the threads of my reason one by one. The feeling of her breasts pressed against my back was so hot it seemed to envelop my whole body. When her fingers finally squeezed the base hard and her thumb pressed the tip several times, I could no longer hold back.

At the moment of climax my hips bucked hard, releasing everything into the water. Her fingers kept moving until the end. She quietly received the pulsing throbs. The water turned milky. Still breathing heavily, she slowly withdrew her hands.

She smiled with a hint of satisfaction and stepped out of the tub.

"Thank you. You looked like you enjoyed it very much."

Her voice was calm, as though we had just had an ordinary conversation. Still lost in the afterglow, I watched her back as she left. Only the quiet sound of the sliding door closing lingered like an echo.
