Kathy thought for a while. Cleave or ball gag?
"I'm sorry, what?", she asked carefully. She could feel Lisa's body shifting behind her.
"A cleave gag uses cloth, like the one when you walked in on me earlier." She was grinning, Kathy could feel it in her very soul. "A ball gag is the rubber one you gagged me with."
Kathy got to thinking again. The ball gag had been an arousing sight, framed by her roommate's lips, forcing her to drool over time and muffling her speech. And perhaps rubber was a better choice, a piece of cloth might dry out her mouth eventually if it were to be stuffed in there for a little while.
"I'll have the ball gag please.", she responded quietly.
"Fine choice, Miss. Two or three inches?"
Kathy's eyes widened slightly. "Three inches!? How could you even--"
"Yeah, bad idea. Your mouth is too small and even if I manage to squeeze it in, it'd probably be too much of a strain on your jaw."
Kathy gulped. But it was too late to take back her request. Or so she told herself. Surely, if she changed her mind, Lisa would understand. But she wanted this, she definitely wanted this, she had made up her mind. Any doubt would only ruin it for her. Lisa was with her, Lisa would keep her safe.
"You okay?" Kathy looked over her shoulder to catch a glimpse of Lisa's worried expression.
"I'm fine, really.", she quickly answered, "Please proceed."
"Well, okay.", Lisa said with a shrug and moved away with one of her arms, presumably to get the gag. "If you have enough and you want out, grab my belly and pinch me, as hard as you have to. Can you do that?"
Kathy opened her hands and pressed her fingers to her friend's warm body. She pinched her skin.
"Yeah, no problem." Kathy grinned herself. "You're getting a bit chubby there."
"No, I'm not!", Lisa exclaimed, caught off guard, "You're getting chubby!" And with that, she pinched Kathy's side, making her squeal and giggle playfully, pulling at the ropes.
"You've been lazing around and playing video games too much lately!", the redhead continued her teasing, feeling a little more confident after having spent a few minutes tied up already. "And the tortilla chips I bought last week have disappeared quite quickly as well."
"You little--! That's it, open up!"
Kathy was about to continue her jabs, as a rubber ball was pressed against and passed her lips into her mouth. Lisa pressed it behind her teeth and buckled the gag behind Kathy's head, pulling her hair aside to do so.
"There, that should keep you from spouting more nonsense.", the tanned athlete exclaimed, content with her gag job.
"Hmmph...", Kathy said, trying to get words passed the gag. "Ah ggn mmnnh..."
"Yeah, whatever." The grin had returned to Lisa's voice. "Now about that second part." She pressed her breasts against her captive's arms and back, her hands caressing the pale girl's belly and hips. "You asked me to make you cum? Seriously? You really sure about that?"
Kathy nodded and mumbled into the gag. It was useless, Lisa wouldn't understand her, but she loved to try.
"Okay then. I'll be gentle, okay?" Lisa's voice was now a whisper, flowing into Kathy's ear. It felt sincere and caring, but at the same time superior, in a strange tone that made the tied girl's insides flutter with excitement.
The tanned girl's hands slowly crept upwards along her captive's sides, heading for the chest, past it and finally reaching the straps of the redhead's white bra. Lisa let them slide down over the shoulders, after which she pulled down the bra, exposing the already hardened nipples to the slightly cool air in the room.
Kathy wriggled and twisted in the bonds, as her friend's fingers settled around her nipples, gently teasing and pinching them, at the same time as soft lips started planting kisses all over her neck. Shivers ran down her spine and she kept moaning and sighing as pleasure built up inside her body.
This was different. Different from what it was usually like when she was intimate with someone, different from what it was like when she was helping herself to a good time. She didn't have to do anything, she couldn't do anything. She was completely dependent on Lisa. And Lisa's skills were incredible, both in bondage and in playing with her body.
In the meantime, Lisa had moved on from pinching and teasing, to grabbing Kathy's breasts and massaging them, making her captive's back bend and extracting muffled moans of pleasure from her.
"You like this, hm?", a soft voice whispered, "You like being touched like this, yes?"
Kathy answered with a long moan, her breathing already quite faster than before. Lisa's hand moved further down, across the flat belly, to Kathy's crotch. Gently touching the panties, she grinned again.
"You're dripping wet, you naughty, naughty girl." Her fingers slipped into the panties. Kathy's breath quickened and she gasped audibly. "I bet you can barely contain yourself. Want me to help you out?"
There was a pause that felt like forever. A small eternity until Kathy realized the question was not rhetorical. She nodded with a pleading mumble.
"Okay then..." Two of Lisa's fingers slowly crept deeper into Kathy's pants, passing by the clit, making the helpless girl shiver and fight her restraints playfully. The fingertips touched her lower lips and parted them before slowly and gently sliding in.
She had made a mess. Kathy's face was red, she didn't dare look at her friend, who was undoing her restraints. She didn't know what to say or do, so she just waited.
"So, I take it you liked it?", Lisa began, breaking the awkward silence that had started to built.
"Yes. Thank you.", Kathy answered, and after a little thought added: "It felt so good... I never felt like that before."
"The magic of bondage.", Lisa smiled and pulled the last length of rope away from her friend. "Let's clean ourselves up, we can talk after that."
