Forbidden Experiments

Chapter 1: Midnight Intrusion

The auxiliary lab of the secret military base was a tomb of silence at this hour, save for the faint hum of machinery and the occasional scratch of Juno’s pen against her notepad. The dim overhead lights painted her slim frame in soft gold, her fitted lab coat clinging to her curves as she hunched over her workstation. Her mind, pure as the Martian air she’d grown up breathing, was lost in mech simulation data, oblivious to the predator stalking the sterile corridors beyond.

Dva moved like a shadow, her pilot’s boots silent on the tiled floor. She’d been restless for hours, her thoughts consumed by the shy scientist she’d glimpsed months ago during a briefing. Juno’s ass—round, firm, a perfect bubble straining against those tight pants—had become an obsession, a fantasy that fueled her late-night cravings. Tonight, with the base quiet and her hunger boiling over, she slipped into the lab, the door locking with a soft, predatory click.

Juno spun on her stool, wide eyes flashing with surprise. 'D-Dva? What are you doing here? This area’s restricted after hours.' Her voice quivered, a cocktail of innocence and confusion that made Dva’s pulse thrum.

Dva’s grin was feral, her gaze dropping unapologetically to Juno’s hips as she licked her lips. 'Oh, Juno, I’ve been waiting for this. You’ve got no idea how long I’ve wanted to get my hands—and my mouth—on that perfect ass of yours.' She stepped closer, her athletic frame radiating raw intent, the faint musk of post-mission sweat cutting through the lab’s sterile air.

Juno’s cheeks blazed crimson as she backed against the workbench, heart pounding. 'W-what? My... ass? That’s ridiculous. We’re colleagues. What could you possibly mean?' Her fingers twisted nervously in her coat, her sheltered Martian upbringing leaving her clueless to the heat in Dva’s stare. Intimacy beyond textbooks was a foreign concept—let alone something so... primal.

Dva didn’t waste time on explanations. In two swift strides, she closed the gap, her hands seizing Juno’s waist and spinning her around to press her against the cold metal table. 'Your ass is a goddamn masterpiece—plump, round, begging to be devoured. I’ve had my share, but yours? It’s in a league of its own.' Her voice was a low growl, fingers already tugging at Juno’s pants, yanking them down with a rough jerk to reveal that flawless rear. The pale cheeks jiggled under the harsh light, a faint sheen of sweat from the long shift glistening like an invitation.

Juno gasped, gripping the table’s edge, her body rigid with shock. 'Dva, wait—oh no, you can’t! That’s... private! People don’t just... touch there!' Her protest was a whisper, laced with naive horror. The cool air on her bare skin made her squirm, but Dva’s commanding presence pinned her in place, a forbidden curiosity flickering beneath her panic.

Dva dropped to her knees, her face inches from that untouched perfection, inhaling the subtle, warm scent—a mix of clean sweat and raw innocence. 'Oh, they do, sweetheart. And I’m gonna show you just how good it can feel. Spread for me, just a little.' Her hands gripped those soft cheeks, prying them apart to expose the tight, shy pucker nestled between. Without hesitation, she leaned in, her tongue dragging a slow, deliberate path along the cleft, tasting the salty tang of Juno’s skin, a flavor purer than any she’d ever savored.

Juno jolted forward with a yelp. 'Ah! Dva, that’s disgusting—stop, it’s dirty!' But even as she protested, a strange heat sparked deep within her core. The wet warmth of Dva’s mouth on such a forbidden spot sent shivers racing up her spine, her innocent mind reeling. Her pussy clenched involuntarily, a trickle of arousal betraying her confusion, the alien pleasure building like a storm she couldn’t name.

Dva’s chuckle was dark, her tongue circling with relentless hunger. 'Dirty? Nah, it’s divine. Your ass tastes like pure temptation, Juno—sweeter and tighter than I ever imagined.' She pressed harder, lips parting to suckle at the sensitive rim, her breath hot and heavy as she probed with wet, insistent pressure. The lab echoed with the obscene sounds of her feast—sloppy licks and sharp gasps—as Juno’s trembling legs hinted at a surrender she didn’t yet understand.

Juno’s breaths came in ragged bursts, her slim frame quaking. 'I... I didn’t know it could feel like this. It’s wrong, but... oh, don’t stop?' Her voice cracked with wonder, her hips twitching back instinctively, offering more despite her mind’s protests. The tingling heat from Dva’s tongue was overwhelming, her body awakening to a raw, pulsing need.

Dva’s hands kneaded those perfect cheeks, spreading them wider as she buried herself deeper, her own arousal soaking through her suit. 'That’s it, let me in. I’m gonna make this ass mine, make you feel every inch of my hunger.' Her words were a promise, her tongue pushing past the tight barrier, tasting the inner warmth as Juno’s gasps turned to moans. The air grew thick with tension, the promise of something explosive teetering on the edge as their forbidden dance ignited in the heart of the silent lab.
