Nobody noticed what happened underwater. Tomiko’s soft hand had instinctively wrapped around my thick cock for those few forbidden seconds in complete secrecy.

As she tried to regain balance, Tomiko slipped again and fell forward — straight into my arms. Her completely naked, wet body pressed flush against mine. Her large, soft breasts squished heavily against my chest, her stiff nipples dragging across my skin.

At the same time, my rock-hard cock slid between her warm thighs and poked firmly against her lower belly, the swollen head nestling right between her slick pussy lips.

I gasped. "Hmm... Oba-san... I’m sorry..."

Tomiko’s eyes flew wide open in utter shock and humiliation. She could feel every throbbing inch of my thick cock pressed intimately between her thighs — hot, heavy, and pulsing against her most private area. A tiny, involuntary whimper escaped her lips as her pussy lips kissed the underside of my shaft.

She tried to pull back immediately, her face burning with extreme embarrassment. "J-Jack...!" she whispered frantically, voice trembling. But the moment she put weight on her right foot, sharp pain shot through her ankle.

"Ah—!!"

She limped and collapsed forward again, falling completely into my arms. Her naked breasts mashed harder against my chest while my cock slid even deeper between her thighs, the head now rubbing directly against her wet slit.

Kasumi’s eyes widened with worry. "Tomiko! Are you okay?! What happened?!"

Haruna looked concerned but also slightly amused. "Aunt Tomiko! Did you slip? Are you hurt?!"

Yuko’s voice was full of panic. "Oba-san! Your foot! Is it bad?!"

"I-I’m fine, Sister... Really..." Tomiko tried to answer, but her voice was shaky and breathless. Her face was glowing bright red with shame.

She was painfully aware that my thick, throbbing cock was still trapped between her thighs, the head nudging against her entrance with every small movement. She wanted to die from embarrassment.

She tried to stand once more, but the pain made her cry out softly.

"Aaaaa... nnnh...!"

Her legs gave out again. She clung tightly to me, mortified.

I held her securely against my body and looked at the others. "Looks like Oba-san hurt her ankle when she slipped. I’ll carry her back to her room so she can rest properly."

Kasumi looked extremely worried. "Jack, be careful with her! Tomiko, does it hurt a lot? Should we call a doctor?"

Haruna nodded, concern in her voice. "Yeah, don’t force it, Aunt Tomiko. Jack, carry her gently, okay?"

Yuko looked like she was about to cry. "Oba-san... please don’t be in pain..."

Tomiko could only nod weakly, too embarrassed to speak. Her heart was pounding wildly. She was completely naked, pressed against me, with my hard cock still rubbing between her thighs.

I turned around and climbed out of the Onsen first. The cool night air hit my naked body. I quickly grabbed my bathrobe and threw it on, though my erection still created a very obvious tent. Everyone got a clear view of my firm ass as I bent over.

Haruna quickly handed Tomiko her bathrobe. Tomiko, still blushing furiously, put it on while still in the water. The thin white fabric instantly became see-through, clinging to every curve of her body — her hard nipples, the shape of her heavy breasts, and even the outline of her pussy were clearly visible.

I stepped back into the water, bent down, and lifted Tomiko up in a princess carry. She let out a surprised, embarrassed yelp as I cradled her against my chest. Her wet, see-through bathrobe stuck obscenely to her skin. One of her breasts nearly spilled out completely. My hard cock pressed firmly against her ass and thigh through my own robe as I carried her.

Tomiko wrapped her arms tightly around my neck, hiding her burning red face against my shoulder. "This is so embarrassing..." she whispered so quietly that only I could hear. "Everyone is watching... "

I carried her all the way to her private room while the others watched with concern. Once inside, I gently lay her down on the soft futon bed.

Tomiko’s wet bathrobe was completely soaked and see-through. It left almost nothing to the imagination.

"You can’t wear this... " It’s completely wet," I said softly, looking at how the fabric clung to her stiff nipples and the curve of her pussy. "I’ll ask Mrs. Saki to help you change into dry clothes."

Here’s the greatly expanded (roughly 4x longer), super erotic version:

Tomiko blushed an even deeper shade of red, the color spreading all the way down her neck and chest. She lowered her head, unable to meet my eyes, and gave a tiny, shy nod.

"O-Okay..." she whispered, her voice so soft it was barely audible. Her thighs pressed together tightly under the drenched, see-through bathrobe. "Thank you... Jack..."

Her entire body was trembling — a chaotic mix of overwhelming embarrassment, lingering arousal, and the vivid, burning memory of my thick, hard cock rubbing directly against her slick pussy lips just moments ago in the Onsen. Every time she shifted even slightly, she could still feel the ghost of that throbbing heat between her legs.

I gently laid her down properly on the futon and stepped out of the room. I returned to my own room, quickly slipped on a pair of underwear to hide my still-very-hard cock, then changed into the elegant dark navy yukata prepared for me. The soft fabric felt cool against my skin, but it did little to hide the prominent bulge at the front.

Once dressed, I walked out into the main hall to find Mrs. Saki.

She was sitting gracefully near the entrance area. The moment she saw me, she stood up with a respectful bow, her heavy breasts jiggling enticingly in her tight red kimono.

"Mr. Jack, how can I help you?" she asked with a warm, professional yet slightly seductive smile.

I explained the situation calmly: "Tomiko slipped in the Onsen and hurt her ankle. She’s resting in her room now, but her bathrobe is completely soaked. Could you please help her change into dry clothes and bring some ointment for her ankle?"

Saki nodded without hesitation. "Of course. It would be my pleasure."

She followed me back to Tomiko’s room. When we entered, Tomiko was still lying on the bed in her wet, see-through bathrobe. The fabric clung obscenely to her body, clearly outlining her hard nipples and the soft curves of her breasts and pussy.

"I’m so sorry to bother you, Mrs. Saki..." Tomiko said weakly, covering her chest with her arms, her voice filled with embarrassment.
