"I...I can't do this..." Katsuragi whimpered, looking uncomfortable despite the expensive-looking padded chair she was sitting on. Well, with Zuikaku dressed as she was, it couldn't be helped.

"Yet you're not leaving." said Zuikaku sultrily as she walked towards Katsuragi, swaying her hips in her see-through white lingerie, stretching her garter-belt. "I'm here just for you, you know, and I'm already dressed up. Am I to...'dress up' again?"

Teasingly, Zuikaku approached the pile of her own clothes that was recently discarded in the middle of the room, and picked up a pair of jeans. She could barely contain her excitement as she observed Katsuragi's pupils widening in panic.

"N...no!" shouted Katsuragi. She then immediately looked like she regretted her words, clutching her own mouth. "I...I mean-"

Zuikaku rushed forward, putting a finger on Katsuragi's mouth. Leaning forward like that, her hanging breasts were just a single muscle movement away from Katsuragi's hands, and Katsuragi was completely aware of that fact, judging from where her sight was focused.

"Shuush, we're here to train you to be more confident, right?" Zuikaku smiled, putting one hand on Katsuragi's. "First step of being more confident is to know what you want."

Zuikaku reached to the table beside Katsuragi's chair and grabbed a set of leash and collar, its colour matching Zuikaku's lingerie.

"Now." Zuikaku pushed the collar into Katsuragi's hands. "Do you want me?"

For a moment the two were still, with Katsuragi looking silently at the piece of leather in her hands while Zuikaku looking expectantly at Katsuragi, smiling reassuringly. Then, to Zuikaku's delight, Katsuragi slowly reached around Zuikaku's and tightened the collar around her neck.

"N...now what?"

Zuikaku leant forward even further, her body almost touching Katsuragi. She then raised her neck, giving Katsuragi a clearer look at the collar around her neck.

"I don't know." Zuikaku smiled. "You're the one holding my leash."

Katsuragi looked absent-mindedly at the rope in her hand.

"Oh, right."

Zuikaku chuckled at the cluelessness of her junior. Then, she took a step back and started standing on her knees with her hands limp by her side, leaving her front completely open.

"I will not do anything unless you order me to."

Katsuragi stared in silence, and then continued staring. It was obvious that she was conflicted, there's a part of her that simply refused to defile the body in front of her. However, the constant temptation of a basically naked Zuikaku looking extremely vulnerable in front of her was simply too much for Katsuragi.

"I'm sorry."

Suddenly, Zuikaku felt a choking sensation around her neck as Katsuragi violently yanked her leash, making her fall forward and straight into Katsuragi's lips.

"Mmph?!"

As Katsuragi assaulted the inside of her mouth, Zuikaku could barely hear the sound of ripped fabric as the little amount of clothing protecting her decency was forcefully torn, leaving her chest bare for Katsuragi's hand to play with.

A wave of pleasure struck Zuikaku as Katsuragi began pinching, rubbing, and pulling on one of her nipples without mercy, buckling her knees. Katsuragi immediately exploited this moment of weakness to put her other hand inside of Zuikaku's panties, putting Zuikaku in the middle of a three-pronged attack.

The sensation was immense. Zuikaku felt like she was being burned and electrocuted at the same time. She wanted to scream, but Katsuragi did not allow her as she tied her tongue with her own, not even allowing her to breathe. Meanwhile, Katsuragi's fingers continued to work, driving Zuikaku ever closer to insanity.

Finally, Zuikaku couldn't take it anymore. Her eyes rolled back, and soon she began losing control of her own muscles. Her entire body tightened, arching her back and pushing her breasts further into Katsuragi's welcoming hands, while at the same time pulling her mouth away, allowing Zuikaku one big, pleasured scream before her entire body suddenly went limp.

Zuikaku fell onto Katsuragi, one of her breasts landing right on her face. Her entire body was twitching, and although Katsuragi's hands had stopped moving, one of her fingers was still inside her, keeping her in a state of constant micro-orgasms.

Panting heavily, Zuikaku wondered if she had always been that sensitive, but deep inside she knew that this was not the case. Was Katsuragi that much of a natural?

"That...that's good." Zuikaku said, smiling weakly. "I guess I've found someone to call whenever I'm feeling...submissive."

Katsuragi's reaction was not as Zuikaku had hoped. She immediately put her mouth forwards and began to aggressively suck, lick, and bite on one of Zuikaku's breasts and nipples, forcing the older carrier into an involuntary jolt.

"W...wait! Katsuragi! Let's rest a little..."

Katsuragi responded to Zuikaku's request by shoving the girl with her leg, pushing her onto the floor. Zuikaku immediately tried to get up, but her weakened legs could not get her up fast enough before Katsuragi pulled on her leash, forcing her onto the floor again.

Before Zuikaku could actually process the situation, Katsuragi began walking around the room, yanking on the leash and forcing Zuikaku to desperately follow her on all four like a dog just to be able to breathe. Her tired limbs, however, could not maintain the action for long, and soon she fell on her back.

Katsuragi did not cease pulling.

"Cough!...gakh! W...wait!"

The half-naked Zuikaku on the floor struggled to breathe, pulling on her leash. But Katsuragi dashed forward and mounted her, putting all of her weight on Zuikaku's chest, making it even harder for Zuikaku to draw air.

"P...please..."

Zuikaku could barely see Katsuragi's hand moving before she suddenly felt a sting on her cheek. It took a couple of seconds for Zuikaku to realise that Katsuragi had slapped her.

"Wait..."

Katsuragi slapped her again...

"Stop..."

...and again.

"Katsuragi..."

Each time Zuikaku opened her mouth, Katsuragi slapped her. She kept trying to beg for Katsuragi to stop, but after each slap her words got weaker and quieter, until finally she stopped talking entirely.

"You haven't received my permission to talk, bitch." said Katsuragi as she licked the tears that had begun running down Zuikaku's cheeks, her tone much different than it was a few minutes ago. "in fact..."

Zuikaku felt her collar being pulled as Katsuragi put her fingers around her neck and began to strangle her.

"I don't think I will let you say anything this entire night."

Zuikaku would not be given the chance to regret the monster she had unleashed before Katsuragi made her scream again.
