"Kathy. Hey!"

"Huh?" Kathy looked up at the other girls at the table. They looked back at her with a confused look.

"Are you okay?", one of her classmates asked her.

"Yeah, I..." She looked down at her phone again. "I'm... fine..."

The message was from Lisa. It was a close-up picture of her. The dark-haired girl was wearing nothing but a lacy red bra and a black collar. A pink rubber ball filled her mouth, accenting her red, glossy lips. She visibly smiled around the gag. Below the picture was a single line of text: Come home early?

"I gotta go! Let's study some other time!" Kathy grabbed her bag and left the table in a hurry, leaving her two confused friends behind.



"Lisa?"

She kicked off her shoes and dropped her bag on the floor. Dropping her keys into the key bowl, she advanced into the living room.

"Hmhm hmm~!", Lisa, sitting on the couch, mumbled, smiling at her around the gag. She was really dressed in only her lacy underwear, leather straps binding her legs, while her upper body was wrapped up in a leather harness, her arms behind her back. A single key dangled from the D-ring of her collar.

Kathy's lips curled into a smile as she walked up to her roommate, eyeing her curiously.

"Well, hi." She touched Lisa's shoulder and sat down on her lap, straddling her. "This is a nice surprise. Is that harness new?"

Lisa nodded with a confirming mumble and leaned forward, pressing against her. Kathy felt a shiver go through her body. She hadn't really been this close to her in a while. Since the events at Caitlyn's house a few weeks before, they had more or less taken turns playing with Jen instead.

Kathy hugged her friend and looked over her shoulder, down at her hands. She was wearing leather cuffs on her wrists, the D-rings connected to one of the rings in the harness with a small padlock. That was probably what the key on the collar was for.

"You did a nice job.", Kathy praised, as if she hadn't been the student not so long ago, "All that for me?"

She leaned back a bit, put her arms around Lisa's neck and looked her into the eyes.

"You know, I had a study group." She narrowed her eyes to a glare, without losing her smile, putting the index finger through the collar ring, pulling her a bit closer again. "I hope you can make up for interrupting it."

"Mmh...", Lisa whimpered, struggling in vain as if to further demonstrate her helplessness, while looking up at Kathy pleadingly, drool already dropping into her cleavage from having to wear the gag.

Kathy leaned down to lick drool from her plaything's chin, gently pulling her head back by the hair as she did so.

"I think I know what to do with you.", she whispered, "I'll be right back."

She stood up and headed for her bedroom, leaving Lisa behind to wait.



Lisa waited. She had already waited before and might have even longer if Kathy had not reacted to her bait, though, of course, Lisa had predicted she would.

But now that she was finally home, she let her wait again. The bindings were already arousing enough by themselves, without more teasing from the redhead.

The harness was exactly right. She could feel the strict hug of the leather wrapping around her chest and stomach and digging into her crotch.

The wrist cuffs and leg straps were similarly tight and the gag effectively sealed off most of her voice, thanks to the balled-up piece of cloth she had stuffed her mouth with before using the ball to keep it in.

Any kind of turning and struggling seemed to tighten the leather around her chest, enticing little moans and huffs from her every time.

Kathy had increased her arousal by touching and licking her and whispering little promises of possible punishment, only to leave her again, to struggle on her own and think about what her mistress-of-the-day would plan for her.

The clock was out of view so Lisa didn't know how much time had passed until she heard the door open again. Kathy smoothly moved back into her vision, slowly stepping in front of her. She had dressed down to her underwear as well, wearing a white bra and panties.

"Get up.", Kathy smiled as she grabbed Lisa by the harness to help her stand up. She then took her by the collar and pulled lightly. "Now hop."

Her smile grew into a grin as Lisa carefully started to bunny-hop after her, being led towards Kathy's room, her chest slightly jiggling with every hop. Kathy whispered and smiled, slowly leading her on, until they finally reached the bedroom and the redhead shut the door behind her.

Standing still, Lisa awaited whatever would come next as an audible slap to her rear caught her off guard. Her surprised yelp turned into a moan and she wiggled her ass, coyly asking for more. Instead, she felt Kathy's body move up against hers, her chest touching her back, her hands resting on her framed breasts.

"You'd like that, wouldn't you?" Lisa nodded in response and earned herself a breast squeeze.

"Don't get smart with me. Do you think I can't be cruel like the others?" Kathy's breath tickled Lisa's neck. In turn, she tickled Kathy's stomach, as her hands were locked in a convenient position to do just that. Kathy giggled and pulled away for a second.

"Hey, stop it!", she laughed, slapping Lisa's ass again, lighter this time, making Lisa's own giggle transform into a gasp. "You're not taking me seriously. I'll show you."

She pressed up to Lisa's back again, placing her fingers over her breasts, where she pulled down the cups of the red bra, exposing the already hard nipples to the chilly air of the air conditioned room.

"I looked through the new stuff you bought.", Kathy whispered as she stepped away again, obviously getting something from her desk.

Had there been something there? Lisa had been preoccupied while being led in and didn't have a chance to check.

Kathy returned, her body snuggling up to Lisa's one more time.

"I like these.", she grinned, grabbing Lisa's left tit, squeezing it to make the nipple stand out more. Lisa looked down as her mistress attached a clamp to the nipple and repeated the process with the other tit. She recognized the clamps. They were padded and didn't hurt much but they had a built-in--

Lisa moaned into her gag as the vibrators teased her nipples. She turned and wiggled, enjoying the tight embrace of her harness more than before.

"Move, slave. To the bed." Another slap sent her on her way. Lisa hopped over towards the bed. It wasn't far, but the clamps added extra weight to her nipples that pulled with every hop. As she stood in front of the bed, Lisa felt Kathy grab the harness again, turning her around.

"Are you having fun so far?", Kathy asked with a smile and Lisa responded with a moaning nod.

"Good." The redhead pushed her helpless friend backwards onto the bed and helped her pull up her legs, making her lie sideways. "Because I'm not done yet."
