Busty Boss's Titjob During Late-Night Office Overtime
In the rainy season, a downpour filled the night. As a new assistant in an ad agency's creative studio, I worked overtime past 1 a.m. Empty desks echoed with my keyboard;

It was the rainy season, with rain pattering steadily through the night.
In the creative studio of an advertising company, I was pulling overtime as a newbie assistant. It was nearly 1 a.m. Raindrops clung to the window glass outside, dimly reflecting the fluorescent lights. The surrounding desks were mostly empty, with only the sound of my keyboard echoing through the office.
Having been with the company for just half a year, every day was a pressure cooker for me. Mika, the creative director, was a tough female boss in her mid-thirties. She was a cool beauty with her black hair tied in a ponytail, always looking sharp in her suits. But her chest was on another level. I noticed it on my first day—her blouse strained against those swells. They had to be at least G-cup monsters. They jiggled with every step, locking my gaze. As a virgin, I jerked off every night imagining those tits... (What would they feel like to touch?).
Suddenly, the intercom on my desk buzzed with Mika's voice.
"Yuma, come to my office right now. I need to discuss the campaign layout."
My heart skipped a beat. Her voice was always low and composed, but for a lowly newbie like me to get called in—probably to chew me out for a mistake. I grabbed my materials in a panic and headed to her private office. I knocked, and she said, "Come in."
Inside, Mika sat at her desk, glaring at her monitor. The air-conditioned room carried a hint of the rainy dampness. Her suit jacket was slightly loosened, offering a glimpse of the deep cleavage through her blouse. I swallowed hard.
"Have a seat. Your idea for this ad's visuals was good, but I want to refine it more."
She pointed to the chair beside her. Up close, her skin was pale and smooth. A sweet whiff of her perfume drifted over. Tense, I spread out the materials and started explaining the layout. Outside, the rainy season darkness pressed against the windows, while the room's soft lighting illuminated her face.
As we talked, Mika leaned in a bit. Her breasts neared the desk, the fabric pulling taut. My eyes drifted there naturally. (Shit, I shouldn't look... but they're so close, that swell...).
"Yuma, focus. Heh, your eyes are wandering."
Mika chuckled softly. I snapped my gaze up, heart pounding. She pointed at the materials, gradually shifting to more personal topics.
"A young guy like you, so dedicated to work—it's admirable. Back in my early days, I was always pulling overtime too. But you need breaks. On a rainy night like this, alone together, maybe something to unwind..."
Her words trailed off, leaving silence in the room. I froze, holding my breath. Mika's eyes seemed to gleam with a seductive spark.
Suddenly, she stood up. Her massive breasts swayed right in front of me, filling my vision. She placed a hand on my shoulder and leaned in slowly.
"Yuma, the truth is, I've noticed you. You always stare at my chest, getting all flustered, right?"
"Uh, Mika, that's not..."
My voice cracked. Smiling, she shrugged off her jacket. Her blouse accentuated those G-cup tits, buttons straining to burst. Amid the distant rain sounds, she pulled my chair closer and knelt down in front of me.
"Heh, such a virgin reaction. That's fine—I'll teach you. The secrets of a woman's body."
Mika's hand reached for my belt. I couldn't resist, just stared in shock. (Is this a dream? Reality? Her hand feels so warm...).
She deftly unbuckled my belt and tugged down my pants. My cock was already rock-hard in my boxers. She exposed it, narrowing her eyes as she examined me.
"Oh, it's so stiff. Cute. No experience yet, huh? I'll be gentle."
Her breath hit my cock, making me buck my hips. Mika unbuttoned her blouse and shifted her bra aside. What emerged was beyond imagination—G-cup breasts, white and heavy, sagging softly against gravity, with plump pink nipples erect. Faint veins traced the skin, glistening with a light sheen of sweat under the lights. That cleavage was a deep abyss, promising to swallow my cock whole.
(So huge... real monster tits. I want to touch them, bury myself...)
Mika cupped her massive breasts and enveloped my cock in the valley between them. The soft flesh wrapped around my entire shaft. Warm, slick with sweat and skin friction—it was exquisite. She began moving her tits up and down slowly.
"How's that? Feels good with a titjob? My huge tits rubbing your cock."
"Ah, ugh... Mika, it's too much... so soft..."
I groaned. Her breasts jiggled like jelly, gently squeezing from tip to base. Her nipples occasionally brushed my stomach, sending hard, hot jolts through me. The room's humid air from the rain made sweat pool in her cleavage, creating wet, squelching sounds.
Mika's eyes grew moist as she quickened her pace, savoring my reactions. The weight of her tits pressed down on my cock, my precum lubing the valley for smoother slides. Her breathing grew ragged, her breasts slapping against my thighs in erotic rhythm.
"Feel it more. Your cock's so hot, throbbing. I'll milk it dry with my G-cups."
I nearly grabbed her head but, as a virgin, could only tremble. (Drowning in tit heaven... this sensation, unforgettable. Squeeze harder...).
She varied the rhythm, sometimes releasing her tits to tease my tip with her nipple. The pink bud grazed my head, sparking electric pleasure up my spine. My cock reached its limit, balls tightening.
"Mika, I... I'm gonna cum..."
"Go ahead, cum. Cover my huge tits with it all."
She whispered, pistoning her breasts furiously. The slick valley stroked me at high speed, and I exploded. Thick ropes of semen erupted, splattering white across her cleavage. Some clung to her nipples, stringing out. Mika scooped it up with her finger and licked it clean.
"Heh, you came a lot. Virgin cum is so thick."
I slumped in the chair, panting. Mika wiped her breasts contentedly and buttoned her blouse. But her eyes still burned with heat.
After that, we returned to work as if nothing happened. But Mika started giving me lingering looks and knowing smiles. That forbidden night began to change our relationship bit by bit. Every overtime now makes my heart race, but just recalling the feel of her massive breasts gets me hard again.
The rainy season showers hadn't stopped. But inside, my heart burned with something hot.
