Milked in Cowgirl by a Busty Astronaut on the Space Station

My name is Haruki. At 27, I was just an ordinary salaryman for whom space travel had always been an impossible dream. Thanks to the recent civilian astronaut program, even amateurs like me could seize the chance to spend a week on the station. The rocket launched from Earth, and after several hours of travel, I arrived at the space station right in the middle of daytime. In the seasonless void of space, far from Earth's cycles, my heart pounded nonstop.

The station's airlock opened, and I floated inside, gliding weightlessly. The sensation of zero gravity felt even stranger than expected, with the floating feeling coursing through my entire body. The air was slightly cool, carrying a metallic scent that hit my nose. The station corridors had a futuristic white-and-silver design, with wall monitors softly displaying data in electronic tones. Drifting along with my luggage, I encountered the welcoming astronaut.

"Haruki, welcome. Your first stay in space must be exciting. I'm Aoi, a veteran engineer. I'll give you a maintenance briefing today. Follow me."

Aoi's voice was bright and professional. She looked about thirty, with a voluptuous figure even visible through her spacesuit. What caught my attention most was her chest. The tight fabric emphasized her large breasts, drawing my gaze. Far beyond a D cup—E or F, perhaps. With each step, her breasts floated and swayed slightly in zero gravity, stirring my excitement. I wasn't a virgin, but being this close to a woman's body in such a situation felt like a fantasy turned real. Back on Earth, I never even got to talk to a woman this beautiful.

Aoi led me to the maintenance hatch. The narrow hatch room had tools and panels lining the walls, creating a sealed space. The air felt a bit stuffy, mixed with the sweet scent of her shampoo. In zero gravity, we secured ourselves by gripping handrails and began the work.

"This is the life-support system hatch. I'll teach you the basics so you can inspect it yourself in an emergency. Start by turning this valve."

Aoi moved close beside me, placing her hands over mine to guide me. Her body heat transferred through the contact, making my heart race like a bell. Her breasts lightly brushed my arm. The soft, elastic sensation came through clearly even via the suits. My mind went into panic. 'Getting this close to such a beauty here... what if something happens?' Inexperienced fantasies swelled. Sweat beaded on my forehead, but in zero gravity the droplets floated upward like pearls.

As the work continued, Aoi's breathing grew slightly heavier. In the tight space, our bodies bumped repeatedly, pressing her breasts against my shoulder and arm multiple times. Soft, with weight. That sensation was unforgettable. The scent of her sweat mingled with the metallic smell, stimulating my nostrils—a sweet-tart, feminine aroma.

"Haruki, are you nervous? Your face is red. Space sickness?"

Aoi peered at my face with a smile. Her eyes were deep, her lips full. I quickly looked away.

"N-no, I'm fine. It's just... my first time, and your guidance is so good that my heart's racing."

At my words, Aoi chuckled softly, her breasts swaying again. Their slow up-and-down float in zero gravity resembled an enchanting dance. Heat built in my groin, and I began to react beneath my suit. Dangerous—getting aroused here.

After finishing a section of the work, under the halogen lights, Aoi suddenly turned serious.

"Actually, I'd like to run an emergency maintenance simulation. This hatch is sealed, making it a perfect practice environment. Haruki, I need your help."

She lowered her suit zipper slightly, loosening the collar. Sweat-dampened skin appeared, with a glimpse of cleavage. My gaze locked on it—that valley between her large breasts, clean and pale. My breath caught.

"Huh, help with what...?"

As I hesitated, Aoi took my hand and placed it on her waist. In zero gravity our bodies pressed together, her breasts pushing against my chest. The soft, cushion-like sensation made me tremble all over. Her breath warmed my ear.

"In a real emergency, we'd need to secure our bodies. Like this..."

Aoi's words trailed off as her lips met mine. A kiss. The soft feel of her lips, her moist tongue intertwining. The taste was slightly salty—sweat. My mind went blank. 'A dream? Here, with such a beauty...' I cried inwardly while instinctively pulling her close.

Aoi's suit came off piece by piece. The moment her large breasts were exposed, my eyes fixed on them. Perfect shape, floating naturally without gravity. Pink nipples gleamed under the lights. I reached out, craving the touch. My fingers sank into softness—warm, elastic, making my fingertips quiver.

"Haruki, you're as excited as a virgin. Cute... But today, I'm taking the lead."

Aoi's voice was sweet yet commanding. She pressed me against the hatch wall, entwining our bodies in zero gravity. Sweat floated and sparkled around the room. Her scent grew stronger, fueling my arousal. Her breasts pressed against my face, so soft I could barely breathe. Their weight sank into my cheeks, leaving a sweet-salty taste on my lips.

Things escalated quickly. Aoi stripped off my suit and grasped me. The hot sensation, the softness of her palm. I moaned. Zero-gravity sex was beyond anything I'd imagined. Our bodies floated and intertwined. Her breasts rubbed my chest, friction heat racing through me.

"Forbidden space sex, right here. No one will come... just relax."

Aoi whispered and straddled me. Cowgirl position. In zero gravity, without weight, she slowly sank down onto me. Hot, wet sensation enveloped me. Her inside was soft, gripping tightly. My hips moved on their own.

The climax became a sweaty frenzy. Aoi began rocking her hips. Her large breasts swayed violently. In zero gravity they bounced and rippled up and down, filling my vision. Lost in sensation, I grabbed them. My fingers sank in, flesh overflowing. Sweat scattered, the cool droplets hitting my skin and heightening my excitement. Her moans echoed in the hatch. "Ah, mm... Haruki, more..." Low and seductive, ringing in my ears and making my spine tremble.

Floating movements felt dreamlike. Her hips dominated me, milking me with the rhythm of cowgirl. Inexperienced fantasies exploded. 'With these huge breasts, like this... if only it could last forever.' I came multiple times. First, second... sweat mixed, filling the room with a humid scent. The feel of her breasts—soft, warm, clinging to my body. Sight, touch, everything erotic. Taste: swallowing her saliva in kisses, licking salty sweat. Sound: wet impacts of flesh and her moans. Scent: sweet mix of sweat and pheromones.

On the third climax, I cried out and finished. Aoi shuddered too and collapsed onto me. Her breasts spread across my chest, their soft weight comforting. Breaths ragged, sweat dripping. In zero gravity we rotated slowly, sharing our heat.

The afterglow lingered. The hatch lights dimmed as we embraced while floating. I buried my face in Aoi's breasts, savoring the sensation. Soft, warm—something impossible to experience on Earth. Her fingers stroked my hair as she whispered.

"Well? Unforgettable, that forbidden space sex?"

I could only nod. The day of return to Earth approached, but this sensation would stay with me. I wanted to remain on the station, to taste this experience again. Inexperienced fantasies had transformed reality.
