I nodded and stepped closer to the edge of the onsen, letting my eyes drink in the sight of her naked body shimmering underwater. "Oka-san... are you okay? Did the fever come back?"

She shook her head slowly, water rippling around her floating breasts. "No... I am fine now." As she spoke, she lifted her left arm again and started hammering her shoulder with her fist, trying to loosen a stubborn knot.

The movement made her heavy left tit lift completely out of the water for a long, delicious second — the full, wet globe gleaming in the morning light, dark areola puckered and nipple stiff, water streaming off the curve before it dipped back under with a soft splash, sending ripples across the surface that made both breasts jiggle and sway.

Her hairy armpit flashed fully into view again — that thick, wild patch of black hair wet and shiny, clinging to her skin in the most erotic way possible.

The sight of her natural, unshaven underarm combined with her naked, floating tits underwater was almost too much; it made her look so mature, so womanly, so irresistibly forbidden.

I walked around the edge until I was directly behind her, then dropped to my knees on the smooth stone rim. Without waiting for permission, I reached down and placed both hands firmly on her bare, wet shoulders, thumbs digging gently into the tight muscles.

"Oka-san, let me massage them for you."

Kasumi’s body tensed under my palms. "No... no, I am okay..."

"I’m not okay," I said, voice low and calm as I started kneading deeper, feeling the heat of her skin and the way the onsen water made her slick and warm. "Just let me do it... Oka-san."

She let out a soft, conflicted sigh, her heavy breasts rising and falling faster underwater. "You are really going to pamper me... if you keep doing this... I will not be able to bear to be apart from you..."

"Then I will never be apart from Oka-san," I answered, my fingers gliding smoothly over her shoulders and the top of her back, pressing the warmth of the Hand of Arousal ability into her body the moment I activated it.

Kasumi’s entire frame stiffened, hard back arching, shoulders tightening for a split second before a full-body shiver ran through her. A tiny, involuntary gasp slipped from her lips as the ability flooded her nervous system.

Underwater, I saw her thighs press together tightly, her plump pussy lips clenching visibly beneath the clear water as a fresh rush of slickness leaked out of her, mixing with the hot spring and creating a tiny cloud of her arousal that drifted around her.

Through the open Telepathy link, her thoughts poured straight into my mind, shaky and overwhelmed:

[What is going on...? Am... I... why is there such a reaction down there....? My pussy... it suddenly got so hot... and wet... I can feel myself dripping... leaking into the water... Oh no, why is my body reacting like this just from Jack’s hands...? It’s throbbing... I’m getting so slippery down there... this is embarrassing...]

I kept massaging like nothing was happening, slow, firm circles that pushed the arousing energy deeper into her muscles while her heavy breasts floated and swayed with every shaky breath she took.

Her hairy armpit was still raised slightly as she tried to stay composed, the thick black curls glistening, her dark nipples now fully hardened and poking prominently against the water’s surface.

Kasumi bit her lower lip, cheeks burning darker, eyes half-lidded as another wave of heat bloomed between her legs. Her thoughts kept spilling into my head, growing more desperate:

[It’s getting even wetter... my pussy is clenching on its own... I can feel the slickness coating my thighs underwater... Why does Jack’s touch make me like this...? I’m an old woman... I shouldn’t be getting this soaked just from a shoulder massage... but it feels so good... I’m dripping so much...]

I kept my hands steady on Kasumi’s wet shoulders, the Hand of Arousal still quietly pulsing warm energy into her skin, making her body betray her with every slow circle of my thumbs.

The onsen water rippled gently around her naked body, her heavy, floating tits and those wild, hairy armpits on full erotic display as she struggled to stay calm under my touch. 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

Steam curled around us, making the black curls under her arms glisten even more, damp and untamed, while her dark nipples poked hard just beneath the surface.

Then Kasumi let out a soft, helpless moan that she couldn’t hold back. "Aah... hmm..."

The sound slipped out low and throaty, vibrating through her chest. I chuckled inside my head, but I stopped my hands immediately, pulling them back just enough to look innocent.

"Oka-san, are you okay?" I asked, voice calm and concerned like I had no idea what was happening to her.

Kasumi bit her lower lip hard, cheeks burning bright red. "I... I am fine... It’s just... it felt good..." she whispered, voice shaky.

But the pleasure from the Hand of Arousal had already pushed her too far. In a sudden panic, she tried to stand up from her seated position in the hot spring.

Water cascaded down her naked body in shining sheets as she rose. Her heavy tits bounced free completely — full, pale, and glistening, the dark erect nipples stiff and pointing straight out, water streaming off the undersides in rivulets.

The thick black tufts of hair under both armpits were now fully exposed in the morning light, wet and matted, framing her mature curves in the most raw, erotic way.

As she turned around toward me to climb out of the onsen, her plump ass and the dark patch of pubic hair between her thighs came into full view for a split second — her pussy lips visibly swollen and slick, a thin string of her arousal stretching downward before it broke and mixed with the water.

My cock jumped hard inside my bathrobe at the sight, thickening instantly and creating an obvious, massive tent in the thin fabric. The head of my cock pushed aggressively against the material, the outline clear and throbbing.

Kasumi’s eyes dropped straight to it.

[Is he reacting to my old body...? Oh my god... he saw my tits... he is so hard...] Her thought exploded through the Telepathy link, a storm of shock, disbelief, and sudden shameful excitement.

She froze mid-step, one foot still in the onsen, water dripping from her naked curves. Realizing I was rock-hard because of her, Kasumi gulped loudly, eyes wide. In a frantic rush, she slapped one arm across her heavy breasts, trying to hide those stiff, dark nipples, while her other hand grabbed desperately for the bathrobe she’d left on the stone edge.

Her hairy armpit flashed again as she reached — that thick, natural black bush glistening — making the whole moment even more unbearably erotic. Her thighs pressed together tightly, but I could still see a fresh trickle of her wetness running down the inside of one leg from how soaked the Hand of Arousal had made her.
