Busty Friends with Benefits: Ecstasy in a Secluded Mountain Hot Spring

I'm Kengo, a late-20s amateur environmental artist. I usually create nature-themed installations in urban vacant lots, but lately, the work pressure has been intense. Clients keep throwing unreasonable demands my way, and my head feels like it's about to explode.

That's when I reached out to my friends-with-benefits, Rico. She's a freelance documentary filmmaker—bright and full of curiosity, always willing to listen to my work complaints. We met three months ago at a party through mutual friends, and after a casual hookup that night, we became FWB. Rico's body is seriously incredible. From the moment we met, I knew her breasts were at least G-cup territory—massive and protruding so much that they're obvious even through her clothes, jiggling with every step. That kind of volume is irresistible to a guy like me, who's only recently shed his virgin status. (I wonder what they'd feel like to touch... I've stayed up late fantasizing about it every night.)

On a muggy morning in the rainy season, we set off in the car toward the mountains late in the morning. Our destination was a private, secluded outdoor hot spring in an undeveloped area— a secret spot Rico had found on social media. As we climbed the narrow mountain road with light rain pattering down, the damp air seeped through the windows, clinging to my skin and making my heart race a bit.

"Kengo, it's rare for you to come out to a place this remote. You're really stressed out, huh?"

Rico said with a laugh from the passenger seat. She was dressed in a T-shirt and shorts. The sky was overcast from the rain clouds, but her youthful-looking smile brightened things up. Gripping the steering wheel, I kept stealing glances at her chest. The T-shirt was slightly damp from the humidity, faintly outlining her bra. (Whoa, those huge breasts are asserting themselves again today... Can I hold back?)

We finally arrived. The hot spring was near a small waterfall, surrounded by dense trees. Around 11 a.m., as the rain eased to a drizzle, we set down our bags and changed. We slipped into thin robes like yukatas and headed to the outdoor bath. The tub was enclosed by rocks, with steam rising thickly. The rainy season's humidity mixed with the heat, making it feel steamy and enclosed.

We soaked side by side in the water. The hot bath enveloped our bodies, warming us through. Rico's skin flushed pink from the heat, her collarbone glistening. Her massive breasts bobbed like they were floating on the surface, droplets pooling in her cleavage. (If I got closer, they'd probably sink down and envelop my face...)

"Ahh, this feels great. Kengo, tell me about work."

Rico said, submerging up to her shoulders. I sighed and vented about recent issues—clients ignoring deadlines, skimping on materials. She nodded along, occasionally reaching out to pat my shoulder. Her warm hand made my heart skip.

As we talked, the rain picked up again. The waterfall's roar echoed, and the trees rustled around us. Being private, no one else was there, but it had a suspenseful tension, like a thriller. With Rico's body heat so close, my pulse started pounding like a drum. (Something's about to happen... I can't stop wanting to touch her breasts.)

The non-erotic time ended there. The steam seemed to melt away my self-control. Rico suddenly leaned toward me, her massive breasts brushing lightly against my arm. The softness was squishy and yielding. The weight of those G-cups pressed through, and my groin reacted instantly.

"Kengo, come here. Let's get closer."

Her voice was sweet. She wrapped her arms around my neck and brought her face near. Our lips met in a light kiss, her breath hot with the scent of steam. Unable to hold back, I reached out and parted her robe, grabbing her breasts directly. So big... They wouldn't fit in my palms. The heavy flesh sank under my fingers, her pink nipples shiny from the water.

(Whoa, breasts this soft are like a dream... I want to knead them endlessly.)

"Mmm... Kengo, be gentle."

Rico giggled, but I didn't stop. I pushed her breasts together with both hands, deepening her cleavage, pinching and rolling her nipples. Her body shuddered, a sweet moan escaping. In the water, her thighs wrapped around my legs.

The kiss deepened, our tongues entwining, the taste of saliva hot and intense. Rico's hand slid to my crotch, gripping my cock through the robe. It was rock-hard already. Her fingers stroked gently, and I couldn't stifle my gasps.

"Rico... Your breasts are insane. I've wanted to touch them forever."

I admitted honestly. Rico narrowed her eyes and stripped off my robe. My cock bobbed to the surface. The head was swollen, precum leaking from the tip. She cupped it in her hand, sliding up and down slowly. The slippery feel in the bubbling water was exquisite.

Now Rico pressed her massive breasts against my chest. They flattened softly, covering me like a blanket. Her nipples grazed my skin, sending electric shocks. (This sensation is pure bliss... I want to drown in her sea of breasts.)

She shifted, sliding my cock between her breasts. Titjob time. Her G-cups enveloped me, rocking up and down. The heat of the water mixed with the softness of her flesh, blanking my mind. Her nipples hardened, sweat and steam pooling in the valley.

"How's that? Your cock's so hot. You love being squeezed by my huge tits, right?"

Her words left me nodding helplessly. My cock's veins throbbed, and I fought back the urge to cum. (Not yet... I want to savor this more. The pressure from her breasts is too perfect.)

After the titjob eased, Rico had me sit on the edge of the tub. She knelt in front of me and took my cock in her mouth. Blowjob starting. Her lips sucked gently on the head, her tongue swirling along the underside. Wet slurping sounds echoed in the water. Her breasts bumped my knees, rippling with each movement.

(Rico's mouth is so warm and slick... Her tongue's too erotic; my hips are moving on their own.)

I held her head and thrust lightly. My cock hit the back of her throat, eliciting a gag, but she kept going. Saliva trailed in strings, coating my cock shiny. She fondled her own breasts while sucking, her form ethereal in the steam—curves like poetry, yet raw and real.

Next was cunnilingus. I laid Rico back in the shallow end. Water splashed as I spread her legs. Her pussy was smooth and shaved, juicy like the rainy season air. Her clit swelled plump, pink lips glistening with arousal.

I buried my face and licked her clit with my tongue. Her body jerked, a sharp "Ah!" escaping. The taste was slightly salty, the steam heightening the thrill. (This scent is sweet and tangy... I want to lick every inch of her pussy.)

I slipped a finger inside, rubbing her G-spot. Her massive breasts heaved wildly, splashing water. She pressed my head down, arching her hips. Even as I ate her out, she rubbed my cock with her foot—pure eroticism.

Climax approached. Rico sat up and straddled me. Cowgirl position. Her pussy slowly sank onto my cock. Hot and tight, her walls gripped me firmly, making me writhe in ecstasy.

"Rico... You're inside... Your huge breasts are bouncing."

She started riding, grinding up and down. Her breasts jiggled wildly, slick with sweat and water. Nipples erect, filling my vision. (This motion is killer... Waves of her tits swallowing me. Each thrust feels like my cock's melting.)

Her hips moved faster, her depths pounding my tip, juices trailing down her thighs. Water splashed, mingling with the rain. Tension built like suspense. I grabbed her breasts, kneading hard—fingers digging into the milky softness.

"Kengo, you close? Me too... Ah!"

Her voice rose. Her hips spun quicker, pussy spasming. I hit my limit. My cock swelled, pumping thick ropes of cum deep inside. The hot creampie sensation trembled through us.

Rico collapsed onto me, pressing her breasts to my chest. Our breaths ragged, sweat mingling. The bath's warmth left a pleasant exhaustion.

Afterward, we climbed out and sat on the rocks. The rain stopped, greens vivid. Rico smiled, "Let's come back sometime." I nodded, thinking to myself, (This memory of her huge breasts... I'll never forget it. FWB is great, but I want more.) Work stress eased a bit. But recalling Rico's body reignites my excitement. That secluded hot spring became our secret spot.
