Kathy made eye contact and quickly looked down. Lisa and Jen continued to watch her from the pool in-between moments of swimming, diving and spraying water at one another, laughing and having fun.

In the meantime, Kathy was having a very different kind of fun. Her body strained against leather and rope, the belt below her breasts gave a very little bit of way every time but was still as unrelenting as the others. Her hardened nipples were clearly visible, sticking out under her tight swimsuit and drops of saliva decorated her chest, as she was no longer able to stop herself from drooling due to the gag.

With no other option open to her, she remained sitting on the bench, watching her friends in the pool and waiting for the return of the mysteriously enchanting woman who had left her like this. It took longer than expected - she had been back once only to grab the duffle bag and disappear again-, but she eventually came back outside, herself now dressed in a white front-tie bikini. Smiling and waving at the other girls for a second, she headed directly for the redhead.

Kathy straightened her back as she came close and looked up at her.

"You", Caitlyn said with a flicker of a grin, pointing at her, "are coming with me now."

Without waiting for an answer, she reached around the bound girl, grabbed the belts binding her below the breasts and around her thighs and lifted her onto her shoulder.

Questioningly, Kathy looked back towards her friends as she was carried inside.

"Have fun~!", Jen called out and waved.

"Don't break her, she was expensive!", Lisa commented with her typical grin.



Kathy was dropped onto the couch in the living room. Lyn's hand reached behind her head and unbuckled the gag, taking it out of her mouth. Reaching for a tissue, she wiped saliva off Kathy's chin.

"Thank you.", the red-haired girl said quietly.

Caitlyn smiled at her. "You're really enjoying this."

She sat herself down next to the tied girl and put an arm on the armrest behind her.

"Lisa didn't tell as much, have you had much experience?"

Kathy hesitated. "I... don't want to assume I've seen everything. Lisa put me through a lot and I've done my own research, but I'm sure there is still much I can learn."

"Modest and eager, I like that.", the older one smiled and let her eyes do a quick inspection of Kathy's body.

"Here's the thing, Katherine: I don't want to assume you will just be okay with anything, so I'm asking you for permission: Is it okay if I work on you a little bit?"

Kathy's blush intensified and she looked nervously at the finger running over her upper arm, giving her tingles.

"Uhm... work?"

"Nothing big, mostly harmless stuff. Probably not different from what my student has done to you. I'd just like the opportunity to get another... customer."

"Customer...?" Kathy wondered at the choice of words, but at the same time didn't see any reason to distrust Caitlyn. She was friendly, evidently caring and both Lisa and Jennifer enjoyed her... 'services'.

"I... I'd like that.", she finally answered, "For now, at least."

A brighter smile crossed Lyn's face. She reached under the table, where, as Kathy now noticed, the duffle bag had been placed, and produced the leather blindfold she had used on Jennifer during the shooting.

"Then I'm sure you won't mind wearing this. Keep your head still."

She placed the blindfold over Kathy's eyes and leaned over her a bit to fasten it. The immediate and total lack of vision caught the student off guard. She had been blinded before, but with cloth blindfolds there was always a bit of light coming through, or at least a singular colour. But with this item, all she saw was black. There was no light, the pad perfectly sealing it out. Opening or closing her eyes made no difference.

As she got used to the new feeling, she felt fingers brushing past her legs and the bindings around them loosen. In fact, once her legs were free, Lyn began untying her wrists and freeing her arms as well. A sigh escaped her lips as she could stretch her arms and rub her wrists.

"I'll give you a few seconds to relax. Make the most of it."

Kathy nodded and stretched her arms and legs out, standing up for a moment, just to be silently and strictly pulled back down. The desire to touching her chest and crotch areas made itself known, but she decided against it. Lyn was still next to her, most likely watching and she wasn't sure if she was even allowed to. The redhead folded her hands in her lap and waited.

Full seconds passed before Caitlyn spoke and when she did, she did so with a strict voice, severely lacking the friendliness from before, that sent shivers down Kathy's spine.

"Stand up." She did and felt the older one's hands on her shoulders, turning her by ninety degrees.

"Go." Kathy complied and walked forward carefully, pushed and guided by the woman behind her. She felt the fluffy, white rug beneath her bare feet when she was commanded to stop.

"Kneel." Kathy knelt on the rug and once again folded her hands in her lap, awaiting more orders. A tingly feeling spread through her body as she obeyed the brunette's commands. It felt so absolute, as if there was no way she could ever resist that voice.

The bag was dropped next to her, she could hear it and instinctively turned her head, but it was pushed back into a straight position.

"Give me your arms." She moved her arms behind her back, where her wrists were immediately grabbed and pulled back a little further. Lyn fastened something around them, padded leather cuffs, as Kathy concluded. The same was done to her upper arms, just above her elbows.

Chains jingled and Kathy again turned her head, just to be forced into "looking" straight ahead again. The wrist cuffs were linked together almost directly, effectively turning them into more comfortable handcuffs. The chain was attached to one of the elbow cuffs and led several times around her body below her breasts before ending at the other elbow. Both elbow cuffs were then directly linked as well.

Caitlyn grabbed the chain and pushed forward slightly, yanking at Kathy's leg. Kathy gasped, fearing to fall face first, unable to use her hands to catch herself, but found that her captor gently lowered her onto the ground by the chain, now taking both her legs to work on.

Two bondage belts were re-used, binding her at her thighs and below her knees, her ankles received the same treatment as her wrists. Caitlyn attached another chain to the wrist link.

"Bend your knees." Kathy complied and folded her legs, with a little help from her captor. The new chain was wrapped around the ankle link and pulled up, finally getting attached to the elbow link.

Caitlyn pushed her captive onto the side.

"And now, so you don't get bored..." Kathy heard rustling, followed by the tear of duct tape. Something was pressed to her chest, touching her nipple and both her nipple and the object were covered by tape that was being pressed down with no regard to the sensitivity of the spot it was being used on. The same procedure was then repeated with the other nipple.

"Don't bother looking for the remote, I will take it with me." Both small vibrators started buzzing and elicited a moan from Kathy, making her strain helplessly against leather and metal.

"Now, I will go entertain my other guests, while you will stay here and behave, do you understand?"

"Mmh, yes...", Kathy moaned.

Caitlyn's fingers pinched Kathy's cheek, not enough to hurt but enough to make her wince.

"What was that?", the woman asked sternly.

"Yes, mistress."

"Good girl."

Strict fingers grabbed Kathy's hair and lifted her head a bit. Soft lips touched hers for a brief moment and made her whole body shiver. She opened her mouth, only for it to be filled with a thick rubber ball.
