The first time Maura had ever stolen a bite of Jane's highly suspicious peanut butter and fluff sandwich, she experienced all the classic indicators of sexual arousal. There was just something about the delightfully tempting, tantalizingly delicious mixture of flavours that drove the doctor absolutely wild.

She found herself waking in the middle of the night, a habit she'd certainly never had before her discovery of the mystical food item, and going to the kitchen to make one of her guilty pleasures as a midnight snack. Doctor Maura Isles, the beacon of good nutrition, stuffing her face at an inopportune time with chemicals, and not having a single regret about it.

It was one of those nights, incidentally falling on a sleepover day, that Maura woke at 1:53 in the morning, craving the S'mores-like consistency, the sugar rush of a doughnut, and the taste of a childhood she'd never gotten to experience. She'd really tried to be stealthy as she'd slipped from her bed without jostling the Jane sleeping beside her. Apparently her best efforts weren't enough because just as she'd finished making her snack and taken a bite, the detective softly shuffled into the dimly lit kitchen.

"Maur? What're you doing?" Jane asked, her voice raspier than usual due to sleep. Maura swallowed her mouthful of orgasmic bread and Jane's eyes focused on her. "Are you eating a sandwich?" She sounded almost scandalized. Then her gaze narrowed as she inspected the filling. "Are you having peanut butter and fluff?"

Maura simply nodded, taking another chunk out of the sandwich just before it was whisked out of her hands. The look of outrage on her face almost made Jane laugh.

"You were gonna have this whole thing without me," Jane stated, staring down the medical examiner. "That is so not cool!" And she proceeded to take a huge bite of the almost-gone sandwich. She handed it back and Maura's glare cooled, but only slightly.

In an attempt to appease Maura, Jane bent forward and pecked her sweetly on the lips before tapping her nose softly with a finger.

Maura popped the last of her sandwich in her mouth, smiling broadly as she fully enjoyed it. Jane just chuckled and took her by the hand. "You're too cute."
