Rosa finds the cum

Rosa settled back into her chair and reached for the case file she’d been ignoring earlier. The second her hand brushed the seat of her trousers she froze.

Something wet. Something warm and sticky that definitely hadn’t been there a few minutes ago.

Her brow furrowed. She shifted in the chair, feeling the slick trail slide a little further down the curve of her ass. Slowly, carefully, she slipped one hand behind her and touched the fabric.

Her fingers came away glistening.

Rosa stared at the white strand stretched between her fingertips for a long, silent second. Then her head snapped up, dark eyes cutting straight across the bullpen.

Jake was still sitting at his desk, pretending to look at his computer screen. The second their eyes met he knew the game was over.

Rosa’s expression didn’t change much—just a slight narrowing of her eyes and the tiniest tilt of her head - but the intensity in her gaze was enough to make Jake’s stomach drop. She stood without a word, walked back toward him with that same controlled sway of her hips, and stopped right beside his chair.

“Peralta,” she said, voice low enough that only he could hear. “Stand up.”

He hesitated. She didn’t repeat herself. She just waited, one eyebrow raised, the wet spot on the back of her trousers still faintly visible if you knew where to look.

Jake rose slowly. Rosa stepped in closer, crowding him against the edge of his desk so her body blocked the rest of the bullpen’s view. Her hand came up between them, fingers still shiny with his cum, and she held them an inch from his face.

“Explain,” she murmured, “why the fuck your cum is on my ass.”

Jake’s mouth went dry. Up close he could smell her - leather, gun oil, and now the unmistakable scent of what he’d left on her. His cock twitched traitorously in his pants.

Rosa’s free hand settled on his belt, fingers curling around the buckle like a warning.

“You’ve got five seconds before I decide whether to break your wrist or drag you into the evidence locker and finish what you started.”

Her voice was pure steel, but there was something else underneath it - heat, curiosity, and a dangerous spark that said she hadn’t decided yet which option she preferred.

Jake swallowed hard.

“I… couldn’t help it,” he admitted, barely above a whisper. “You sat right in front of me in that thong and I just - ”

Rosa’s eyes flicked down to the obvious bulge in his pants, then back up. The corner of her mouth twitched - almost a smile, almost a snarl.

“So you nutted on me in the middle of the bullpen like a fucking animal.”

She wiped her sticky fingers deliberately across the front of his shirt, leaving a faint white smear over his heart.

“Evidence locker. Now. And if you make a single sound on the way there, I will end you.”

She turned and walked away without looking back, the wet mark on her trousers still glistening under the fluorescent lights.

Jake stood frozen for half a second, heart slamming against his ribs, then followed.
