This is Why They Invented Doorbells
Omigod!"
The word, shrill-almost like a shriek—was launched like a dart through Michael Burnham's brain, and it added to that first millisecond of confusion, when the scene unfolded before her but her brain struggled to catch up, to make sense of it. Even when the two forms scrambled in a blur of pale, exposed flesh and a great swoop of an blanket pulled up over the naked bodies, Burnham's mind was still puzzling over the details.
The door to her quarters had opened, and there, to her three o'clock, was Tilly in her bunk…
…except Tilly was naked, head thrown back, eyes clamped shut, mouth contorted into a cry of pleasure. Burnham took in the sight, registered the bright pink of her small nipples—pert and erect on the heavy, white breasts—and the long ivory stretch of her legs, dotted with freckles, and slightly spread just enough to accommodate Keyla Detmer's hand.
Detmer: mismatched blue eyes flashing at the intrusion, she was also naked, her face pressed into the veil of fire that was the cascade of Tilly's hair, her own body nearly as pale as Tilly's, but leaner, more taut, the breasts smaller and upturned and still flushed by the touch of a mouth.
"Omigod!" Tilly said, burrowing into the thin protection of the blanket. Detmer didn't try to hide her nudity, but instead straightened up and fixed Burnham with a challenging look.
"I'm…I'm sorry…I'll come back…I'll be back sometime later," she stammered, her composure collapsing like a tower made of straw. She backed out of the room. "I'll knock…When I come back I'll knock…"
Mercifully, the door to quarters shut, and Burnham took a deep breath, tried to blink the image away. She wondered if she could successfully open an airlock and climb inside before the sensors triggered a lockdown...
"Michael Burnham to the Captain's ready room." Saru's voice warbled out of a comm panel beside the door. Burnham punched it.
"On my way," she answered. She silently thanked every deity that ever existed for the distraction.
