Kathryn waited a minute to see if Seven would tell her to stop. She didn't. Kathryn peeked around to see the Borg had her eyes shut, a small smile playing on her lips.
Guess our resident Borg has a masochistic streak, she thought gleefully.
She knew this was wrong. On so many levels. Seven was a member of her crew. She was her captain, her mentor...but Seven had interrupted her in the middle of a play session and it was hard to turn it off. She had intruded and now she was chained up, naked and willing...
With a flick of her wrist Kathryn brought the flogger down across her back again. Seven gasped but did not cry out. She struck her again and again, keeping time with the beat of the music.
After several minutes Kathryn stopped to admire her work. The pale flesh of Seven's back was warm and red. She frowned slightly when she saw her ass looked as though it had never been touched. She gave several quick lashes to her ass, only to see the red of her back fading.
"Nanoprobes," she muttered to herself, frowning.
"...Ma'am?" Seven asked, without moving.
"Just thinking I may need a different tool. Are you okay with that?" she murmured, trailing her fingernails lightly down the Borg's spine, pleased with the shiver she elicited.
"You may do whatever you like to me, C- ma'am," Seven said simply, causing a surge of moisture between the captain's thighs.
"I can?" she murmured, pressing herself close so she could trace the curve of Seven's ear with her lips.
"Yes ma'am."
"Can I...bruise you? Hm?"
"Yes ma'am."
"How about...cut you? Can I carve my name into your back?"
A shudder went through the Borg and Kathryn could tell if she wasn't chained her knees would have given out and she'd be on the floor.
"Yes ma'am," she whispered.
"Good...very good girl," she murmured, kissing her pale shoulder before going over to the chest in the corner.
She put the blue flogger back in its place and dug through her toy box until she found what she was looking for.
She walked back over to the blonde, unsheathing the small silver dagger as she did. She pressed the flat side of the blade against Seven's shoulder.
"Do you know what this is?" Kathryn asked.
"A metal, composed of 86.4% silver and-"
Kathryn withdrew the blade and gave her a swift smack on the ass with her open palm.
"Smart ass," she growled and smiled.
Carefully she pressed the tip of the blade to the Borg's skin. She heard Seven inhale deeply and her smile widened. Experimentally she dragged the blade slowly down her back, leaving a thin red line in its wake.
"How does that feel?" she asked, watching the blood well to the surface.
"Sharp," she answered.
Kathryn gave her another hard smack on her ass.
"I'm gonna beat that smart ass mouth right off of you," she growled.
"How can my posterior be smart? It does not possess brain matter."
Kathryn paused a moment, brow furrowed.
"Do you really not know what that means or are you being facetious?"
"I know what it means. I was hoping you would hit me again," she admitted.
"Bad girl," she said, smacking her ass again. "I'm going to do so much worse than that to you, beautiful..."
