Teased by My Busty Coworker: A Steamy Workplace Secret

I work as a display assistant at a museum. I'm in my late twenties now. Every day, I'm surrounded by ancient artifacts, breathing in dusty air. During the rainy season, rain pours outside the windows, and the humidity inside builds up easily. Natsuki is a curator, a colleague a bit younger than me. Since she started, the workplace feels a little brighter.

Natsuki has a bright personality and gets along with everyone right away. At first, I just admired her. But I can't forget her figure. Her breasts are really huge. Under her uniform shirt, the buttons look like they're about to pop from the strain. When I first joined, I kept stealing glances at her cleavage and imagined she must be at least a G-cup. They look so soft, heavy, like they'd sink under my touch... Just thinking about it makes my heart race.

One evening during overtime, with the rain sounds echoing through the museum. I'd finished tidying the exhibit hall and was heading to the storage room to put back some documents. Natsuki was there. Her white blouse clung slightly from the humidity, outlining her breasts clearly.

"Yuichi, still here? The rain makes it tough to get home, huh?"

Natsuki smiled and called out to me. I quickly looked away. Just having her breasts in my view makes my head fuzzy.

"Yeah, just sorting some documents. You too, Natsuki?"

"Same here. Looks like it'll go late. Want to do it together?"

With that, she reached for the back of the shelf. As she bent over, her breasts swayed gently, pinning my gaze. I felt my throat go dry. In the air mixed with the scent of rain, her sweet shampoo fragrance wafted over.

From then on, overtime days continued. At first, it was just work talk. But Natsuki seemed to notice my stares and would deliberately lean in with her chest when talking to me. Our light conversations gradually turned personal. One night, alone in the storage room, she said,

"Yuichi, you've been staring at my breasts the whole time, haven't you?"

I blushed and denied it, but deep down, I was thinking (I actually want to touch them so bad...). Natsuki giggled and guided my hand toward her chest. The soft sensation reached my fingertips, and I couldn't resist anymore. From that night, we started a secret relationship. Friends with benefits, that's what it was.

On rainy midnights, the museum's storage room became our hideaway. The sound of rain tapping the windows was like background music. Natsuki's body was always warm, her sweat mingling with the humid air. At first, it was just kissing. But fondling her huge breasts became a habit. When I undid her blouse, her G-cup breasts nearly spilled out. The pink areolas were large, and her nipples stood plump.

"Yuichi, you're so hard already. You like my breasts that much?"

To her words, I could only nod. Her hand reached for my pants, gripping my cock. The feeling of her slowly stroking my hardened length. I couldn't hold back and buried my face in her breasts. Pressing my nose into the soft valley of flesh. A sweet, milky scent filled me, and my excitement was about to burst.

(Ah, these huge tits are like a dream... I want to keep smelling them forever.)

Natsuki stroked my head and whispered in my ear,

"Suck harder. Lick and tease them like you can't get enough."

I took her nipple into my mouth. As I rolled it with my tongue, Natsuki's body shuddered. The nipple hardened, tasting sweet and tangy. I sucked eagerly. With my other hand, I grabbed her free breast. My fingers sank in, overflowing flesh covering my palm. Each squeeze sent ripples through the soft mound, and it was irresistible.

As time passed, our relationship deepened. After weekly overtime, meeting in the storage room became routine. I wrestled with myself inwardly. (Is this okay? I know it's just friends with benefits, but I want more...) But Natsuki's body wouldn't let me stop. Her huge breasts melted my reason. On nights when the rain pounded harder, she'd pin me against the shelf, enveloping my body with her chest. The soft pressure made breathing hard, but the arousal wouldn't quit.

One midnight, entering the storage room as usual, Natsuki was already waiting. She'd half-removed her blouse, her black lace bra supporting her breasts. But with G-cup volume, it looked ready to burst. She pulled me close and kissed me. Our tongues tangled, saliva flavor spreading in my mouth. My cock was already straining painfully in my pants.

"Yuichi, obsessed with my breasts again today? Look at them. It's like they're just for you."

Her words stirred my heart. She unhooked her bra. Her massive breasts fell free, swaying before my eyes. They defied gravity with their firmness, faint blue veins visible. I reached out, but she stopped me.

"Wait. Tonight, I'll tease you with words. Your cock is twitching so much. Just from seeing my huge tits, it gets like this? You're getting so worked up like some eager newbie—it's cute."

(Ah, embarrassing... but I want her to say more.)

I looked down. But Natsuki pulled down my pants, exposing my cock. Precum strung out, my groin hot. She just lightly touched it with her finger. Even that soft contact felt like electricity.

"See, I won't let you touch. You want to lick my nipples so bad, don't you? Beg for it. Say, 'Please let me suck on Natsuki's breasts.'"

With a trembling voice, I said it. Natsuki laughed and brought her chest closer. As my tongue touched her nipple, her breathing grew ragged. But she didn't stop.

"Suck deeper. Your cock is throbbing. It's gotten so thick, leaking from the tip... You gonna come just from my words? Hehe, pathetic. You're so hooked on your busty friend with benefits, probably fantasizing about this even during work."

Her verbal teasing pushed my excitement to the peak. Finally, her hand wrapped around my cock. She moved it slowly up and down. The soft palm's sensation made me buck my hips. Her huge breasts pressed against my face, filling my vision with breast flesh. My breath heated up, scents of sweat and rainy humidity mixing.

(I can't hold it... I'm losing to Natsuki's voice and tits.)

"Come on, come. Bury your face in my huge breasts while I stroke your cock... Let it all out."

Her voice echoed in my ears. In that moment, I exploded. Thick semen coated her hand. My body shook, and I collapsed onto the dusty storage room floor. Natsuki gently pulled my head to her chest and laughed.

"It'll get hard again soon. Yuichi, you've really gone crazy for my breasts, haven't you?"

From then on, the relationship continued. Even after the rainy season ended, we met in the midnight storage room. Each time, I grappled with inner conflict, but drowned in her huge breasts and sweet words. I sometimes wonder if staying just friends with benefits is enough. But I can't forget this thrill. It feels like Natsuki's body dominates everything about me. Even now, hearing rain makes me recall that sensation and tremble alone.
