Five hours later:

Kate was whining in her sleep, and you were nearing the end of a sleep cycle anyway. Your arm wrapped instinctively around her waist, tugging her closer against the front of your body in an attempt to offer her your warmth and comfort. The problem was that now she was flush against you, her skin was soft, and your hands were on her. You had received a reminder of where you had come from, in stark contrast to the way you treated your pet, and you weren't sorry. Natasha sometimes needed to be put in her place as well, she had trained your defiance deliberately. You moved forward slightly, inhaling the smell of her skin and her hair as your grip tightened around Kate's waist. She began to stir in your grip. Her movements did nothing to help you reign in your self-control, and your nails dug into her stomach, making her gasp as her body tensed in front of you. You groaned, moving your hips against her ass as your teeth bit into the back of her neck. Kate whined softly but when her head started turning towards you, you growled, grabbing her hair and pushing her back down into the pillow. "Shhhh baby," you whispered, your fingertips moving over her hips, grabbing her ass hard. She squirmed, arching into you as your hand tapped lightly. "Open for me," you murmured and she shifted slightly in front of you. Kate's whines got louder as your fingers dipped between her legs, finding her as wet as you expected. Your fingertips brushed over her clit and she twitched against you, panting before you moved them back, sliding inside of her easily before pulling them out entirely and withdrawing your hand. Kate whined, making you smirk behind her, not that she could see you.

She whined again at the new, unmistakable sensation of your hand moving against her ass. You were touching yourself, practically growling in her ear, and it was almost more than she could take. Her hands started moving to copy your movements on herself. "No." The order was unmistakable. Kate's hands stopped instantly. "Put them where I can see them." Her palms spread flat on the mattress. Your grip in her hair tightened and you pulled her head back, alternating between your tongue and your teeth as your hips moved with your fingers, rocking against her. "Fuck, you feel so good," your voice was little more than a growl and you could feel Kate's body rocking against yours as she pushed against the mattress, trying to get as close to you as she could get.

"Professor, please, I need you." Her voice was muffled by the pillow you were still holding her into, but you got the gist. Her whines increased as you removed your hand, rocking against her ass instead, using her body for the friction you needed. Your now-free hand wrapped around her waist, finding her swollen clit and rubbing harshly, making her instantly shaky. "Oh fuck," she whined, her fists clenching the sheets to tight you wondered if they would survive. It only took a few more minutes, your teeth buried in her neck, groaning into her as she squirmed desperately beneath your fingers before both of you fell apart, your breathing ragged but in sync as you rode out your mutual high. Kate's body curled in on itself and you wrapped around her securely.

"I've got you, puppy," you murmured, your hand moving over her hips again before sliding back between her legs from behind, making her jerk. "We're not done." It wasn't long before Kate was actively biting the pillow on her own, your other hand now free to wrap securely but not restrictively around her throat, holding her tight against you as your fingers slid inside easily. "See how wet you got me?" Her moans were broken as you found a relentless pace and she was forced to keep up by necessity. "Such a good girl," You murmured into her ear as she began rocking against you, moving with you instead of trying to struggle on her own. She was already close by the way she was squeezing your fingers. You felt the exact moment that she remembered she wasn't in control. Her thighs clenched together, and her entire body clenched. You pushed inside of her further.
