Busty FWB Lactation Handjob at Hidden Mountain Hot Spring
Yuto, a stressed web designer in his late 20s, reunites with his yoga instructor FWB Mio at a secluded autumn onsen for intense adult encounters.

On an autumn afternoon, I drove up the mountain road. I'm Yuto, a freelance web designer usually glued to my computer screen. In my late 20s, when work stress builds up I escape to this hidden hot spring. Today I'm meeting Mio again. Mio is a yoga instructor and my friends-with-benefits. We met at an online event six months ago. It started with chat and quickly became a physical relationship, but we'd been too busy lately and lost touch.
Mio messaged, "Yuto, I want to see you. Let's relax at the mountain hot spring," and I immediately said yes. I still remember how my heart raced when I heard her voice on the phone. Mio is always cheerful, and her supple yoga body is attractive. But what really occupies my mind is those huge breasts. They look like G-cups, with cleavage visible even through clothes. Just imagining them jiggling in yoga wear makes my cock hard from the morning.
I arrived at the secluded mountain hot spring. It was a small inn with a private open-air bath, surrounded by autumn foliage. The air was crisp and the scent of fallen leaves tickled my nose. Mio was already there, waiting in the lobby. She wore a black knit sweater and jeans, the neckline slightly open to reveal a glimpse of cleavage.
"Yuto, it's been a while! You look tired. Let's get in the hot spring right away."
I nodded quickly at her smile. Her bright voice felt good. After checking in, we headed to the private open-air bath. Autumn sunlight filtered through the trees, sparkling on the water's surface. Steam rose gently as we entered wrapped in towels.
"Ah, this feels great. Yuto, come over here."
Mio beckoned from the edge of the bath. Heart pounding, I approached. The warm water enveloped my body and eased the tension in my shoulders. But Mio's towel slipped slightly, clearly outlining her massive breasts. Those soft-looking swells. What would it feel like to touch them? I looked away, but inside my head the fantasy grew. (Mio's tits are huge. Even though she has a body toned by yoga, they're so soft and jiggly...)
While soaking, we chatted about everyday things. Mio talked about yoga, I complained about web design. Laughter echoed. But my eyes kept drifting to her chest. The wet towel clung to her, almost revealing the pink shadows of her nipples. The steam seemed to carry a sweet scent, and I couldn't suppress my excitement.
"Mio, got a boyfriend lately?"
I asked half-jokingly. Mio giggled.
"No. You're enough as my FWB. Hey, come closer. I'll give you a massage."
Her words made my heart leap. Mio placed her hands on my shoulders and drew closer in the water. Her huge breasts brushed my arm. Soft, warm, and heavy. The volume of those G-cups seemed to envelop my body.
(Wow, this is dangerous. Mio's tits are touching me. So soft, sinking in...)
My cock twitched in the water. Mio noticed and smiled mischievously.
"Yuto, are you getting hard? Hehe, cute."
Her hand slid along my thigh, slowly upward. Amid the splashing sounds, my breathing grew ragged. Tension made my mind go blank. Mio's massive breasts swayed right in front of me, the visual temptation overwhelming.
Mio removed her towel. Her enormous breasts were exposed. Lit by autumn sunlight, her white skin glowed. Her areolas were pale pink, nipples plump and erect. Steam gently caressed them. I was captivated, unable to speak.
"You can touch them. You like them, don't you, Yuto?"
Her whisper was sweet in my ear. With trembling hands I touched her huge breasts. Heavy, with incredible elasticity. My fingers sank in, soft flesh overflowing. When I squeezed, Mio let out a breath.
"Ah... gently."
My fantasies exploded. Head filled with erotic thoughts. (Mio's tits, if I buried my face in them I'd probably suffocate. If milk came out I'd want to drink it... no, that's too perverted though.)
Mio pulled my head close and pressed my face into her breasts. My nose buried in the soft valley, mixing sweet body scent with the aroma of the bath. I made muffled sounds while seeking her nipple. Taking it in my mouth, I sucked. Mio's nipple hardened against my tongue.
"Yuto, you look so turned on sucking my nipple... it's weird but cute."
Her words doubled my excitement. Mio's hand reached for my cock. Gripped in the water, a hot wave of pleasure shot through me. My cock swelled thickly, precum seeping from the tip. Mio's fingers gently stroked the head.
(Ah, Mio's hand feels so slippery and good. Grip it harder...)
The lactation handjob began. While sucking on Mio's huge breasts, I surrendered my body. Her massive tits cradled my cheeks, and the fantasy of warm milk crossed my mind. Mio moved her hand in a steady rhythm. The water's resistance made the slow strokes irresistible.
"Yuto, you're so excited. Your cock is twitching."
I groaned while nibbling her nipple. A sense of psychological release made my body tremble. Tension melted away, leaving only pleasure. I kneaded her huge breasts, flesh spilling between my fingers.
Climax approached. Mio had me sit properly and brought her breasts close to my cock. A titjob. She sandwiched my cock between her enormous breasts. The slippery water and soft pressure drove me wild. Every time Mio moved her body up and down, her nipples rubbed and stimulated my tip.
"How is it? Does it feel good with Mio's tits?"
"Ah, it's too much... I'm gonna come."
My fantasies wouldn't stop. (Wrapped in Mio's G-cup breasts. This feels like a dream. I want to press it deeper into the valley and cover it with cum...)
She switched back to handjob, stroking vigorously. Still sucking on her breasts, I couldn't hold back and ejaculated. White semen spread through the water. Thick spurts kept coming, waves of pleasure piercing my body. Mio smiled and stroked my head.
"Quick, Yuto. But we're not done yet."
We continued in the bath. Mio straddled me in cowgirl position. Her pussy swallowed my cock. Wet, hot, and gripping tightly. Her huge breasts swayed before my eyes. I grabbed them with both hands, kneading while thrusting. The sensation of her pussy folds rubbing my cock came through clearly. Her clit was swollen and rubbed against my body.
"Ah, Yuto, so deep..."
Steam blurred my vision, all senses dominated by lust. Sound, scent, touch, everything blended. I came a second time, pouring hot cum inside her. Mio's body trembled as she reached orgasm too.
After getting out of the bath, we continued in the room. On the bed I performed cunnilingus. Spreading Mio's pussy, I licked. The pink folds were wet with a sweet-tart taste. Rolling her clit with my tongue made Mio moan. While she kneaded her own huge breasts, I serviced her eagerly. She also gave me a blowjob. Mio's mouth enveloped my cock, taking it to the back of her throat. The vivid sensation of saliva dripping.
In one night I came five times. Driven wild by Mio's huge breasts, my confused erotic fantasies exploded one after another.
In the morning, I looked back at the steamy open-air bath. A farewell kiss with Mio. Amid dancing autumn leaves, I drove down the mountain. My body was satisfied, but my mind still buzzed with excitement. The feel of Mio's enormous breasts was unforgettable. Our FWB relationship continues, but my fantasies will keep growing. The release in the bath felt like it changed my everyday life.
