A noise woke her up. She sat up, blinking into the darkness, trying to kick her brain into gear to discern what it was that she was hearing. She wasn't used to being woken up so abruptly in this bed, in this guest room – she had always felt safest at Maura's house. Eventually she was able to determine that the noise was emanating from Maura's room down the hall, and when it hit her exactly what the sound was, her eyes grew wide and she blushed so hard she could practically see the heat radiating off her face.

Maura was moaning.

Before she realised what she was doing, Jane was on her feet. She couldn't stop herself from tiptoeing towards Maura's sounds, cursing under her breath the whole way. She stopped just short of the door and covered her face with her hands. What am I doing?, she thought, shifting her weight from one bare foot to the other on the cool floors. Did Maura let a guy in while she was asleep? Was Maura…alone? Did she think Jane wouldn't hear her, despite the door being ajar? Who was she-

"Oh, Jane!"

The detective nearly collapsed on the spot. 'Jane'?! Maura's voice had been breathy and the low, rough tone had sent a shiver down her spine – now she had to see whatever was going on in that room. Through the gap between the door jamb and the door, Jane saw her friend laid out on her bed, covers over one bent knee and the other leg stretched out over them, toes splayed. Maura's silk robe was hanging loosely off her shoulders, and Jane caught herself trying to make out the pattern of the lace on the blonde's black negligee, before her eyes settled on Maura's left hand nestled between her upper thighs. Jane swallowed around a hard lump in her throat, absently pushing the door open slightly wider. Maura's eyes were closed, her head thrown back, tongue slowly massaging a spot on her upper lip. Her hips bucked and she moaned again. Jane stood there, transfixed.

She watched, with a heat growing throughout her body that she wasn't at all familiar with, as Maura touched herself. The ME moaned and grinded her hips up to meet her fingers, biting her bottom lip and letting her head roll across her shoulders.

"Oh yeah," she gasped, her brow furrowing deeper.

Jane was trying desperately to control her own heavy breathing. Why was she feeling like this? Maura was her best friend. She shouldn't be watching this. She should-

Maura let out a long moan, followed by a few guttural sounds, climaxing hard. The brunette felt her heart stopping briefly and fought not to let out a moan of her own. The ME nuzzled her pillow as she came down, letting her hand trail up to the edge of the negligee before bringing it up and slipping her fingertips into her mouth.

Jane whimpered.

Maura opened her eyes at the noise, flushing slightly deeper when she made eye contact with Jane, and tugged on her clothes to cover herself. She seemed to weigh up her options before she smiled a sly smile the detective had never seen before, and said:

"You were amazing, Jane."

Jane fled.
