Going Further

Diana turned back, sparing a glance to reassure the other two before she started to descend into the depression in the centre of the room. Once she was down there, she sunk to her knees, placing both of her ankles in the cuffs which had been provided. They clicked shut as soon as they could, locking her in a kneeling pose. Diana struggled for a moment, testing just how much motion she had. It wasn't a whole lot. The cuffs looked tight, and while she was locked down by them, her legs were **** to spread at a slight angle, separating her thighs and exposing her womanhood. The deeper finger-sized hole was right below her pussy, and as soon as the machine had confirmed that Diana could not move away, there came a low humming sound. A small shaft of metal and plastic rose up from the depression. Lisa watched it, Stacy did the same with a worried look. Diana maintained her composure even as she felt its smooth head press up between her lower lips.

"Here is the ''catch''." The voice said, sounding even more like it was gloating. "The device that you feel pressing into you is part of the blowjob machine. The machine itself is very special. The plastic cock is laced with sensors, so that it translates your motions into the same sort of pleasure a real man would feel in this situation. Then, based on how good said feeling is, the electrical device pressed into your pussy will trigger."

"Electrical device?" Stacy's eyes widened. "You're going to shock her? D-down there?"

"Not if she's good at her job," The voice said. "If the cock is pleasured correctly, and she is judged to be competent at her role, then the device will emit only a low grade electrical charge. It can be quite pleasurable, in fact. Like a tingling feeling which will get more intense the better she makes the cock feel. However, if she is bad - not giving enough pleasure, bad technique or otherwise judged to be failing the exercise, the device will release a short, sharp shock. I understand that this is quite uncomfortable to say the least. Though some slaves apparently like it."

There was a moment of silence, perhaps to allow them to feel like the voice had finished with them for this exercise. But it was not so.

"As for you two, we feel that it would unprofessional for you to simply stand around while Diana there works on her skills. So we want you to masturbate one another."

"R-really?" Stacy squeaked, raising her hands to her mouth. "W-what's the point of that?"

"It's sexy?" The voice suggested. "Really, we want it to earn money. As you were told before, the gym has the right to record and upload footage of anything that happens within these walls. We feel that recording such a scene would significantly increase our revenue stream."

Stacy flushed with humiliation, but nodded slowly. She knew there was no sense in arguing. She looked to Lisa, who suddenly felt rather uncomfortable. it was true that they had performed together before, but most of the world had forgotten that now. Stacy trembled a little, but put on a brave face, nodding towards Lisa.

"This is what life is like for a ****, huh? This is the sort of thing you have to do every day?"

"Pretty much," Lisa admitted. "Though, it feels a lot more embarrassing now that you're involved."

"Really? I didn't notice." Stacy giggled, mixing her nervousness with her sense of humour. "So...um, how are we going to do this? I mean, I've never done this sort of thing with a girl before."

"How do you like to be touched? We should probably start with that."

It was not a question Lisa had ever dreamed she would be asking her best friend. Stacy flushed with embarrassment, and her voice trembled, but she went on, not allowing herself to hesitate.

"Um, well, I sort of like it gentle, you know? With uh, oh god, I can't believe I'm telling you this, Lis', but I like foreplay."

"All right, well..."

Lisa reached forwards, Stacy went to pull away, but stopped herself. Her eyes were wide, unbelieving, but her body felt warm with arousal. Lisa brushed her fingers across Stacy's skin, feeling the the heat there. her friend swayed, Lisa's hands curled about her upper body, sweeping across her shoulders and gently down her arms. It was not the most sexual gesture, but it was a close one. Intimate. The sort of gesture which would be shared between lovers.

Before another moment had passed, Lisa pressed her face closer to Stacy's. Her friend was breathing quickly, her chest rising and falling. She kissed her then. Kissed Stacy. Pressing her lips into the other woman's. She didn't dare push deeper. She didn't want it to feel like a violation. Her own heart was pounding. She hadn't thought she would be told to do this, but at the same time, she was exhilarated. Stacy hesitated for a moment, and then opened her mouth, drawing Lisa's tongue deeper with her own. The two women kissed. Lisa could almost feel the camera on her. Recording what should have been a private and intimate scene for the whole world to see. Somewhere behind them, Diana moaned. There as soft hissing sound as the electrical device came online, and she fastened her lips around the false cock.

Lisa didn't have attention for that at the moment. Stacy took up her whole world. The scent of her friend, the motion of her body. The sway of her thighs and the look in her eyes. It fired up more fiercely than she has thought it would. For a moment, Lisa wondered if she was bi - and if she was, what a way to find out! -but that was swept aside as well as they started to kiss more deeply. Mindful of what Stacy had said, Lisa took her time. running her hands up and down Stacy's sides. Stacy's hands trembled, but Lisa felt her grip her lower thigh, running her fingers over her pale skin. Stacy's other hand rose slowly, moving towards Lisa's face. She a moment, Lisa thought she was going to stroke her cheek, but instead she brushed a strand of hair out of away from her face. The kiss broke, the two women locked gazes.

"Are you ready?" Lisa asked.

"I can't believe I am saying it," Stacy said. "But yes."

This time, they went further. Lisa drew Stacy into a tight embrace, pressing their chests together. Stacy's hardened nipples poked into her own chest, the tiny points of heat made her breath flare and catch in her throat. Lisa's hands moved. One of them stroked Stacy's face, enjoying the soft feeling of her hair. The other swept downwards, tracing a slow but steady path towards her sex. By now, Stacy was quite wet. Lisa felt that as soon as her fingers brushed her friend's lower folds. Stacy flushed with shame, but Lisa shook her head.

"Don't be embarrassed," She whispered. "It's fine. It's only me. We've been friends for ages, right?"

"Y-yeah," Stacy stuttered. "But friends don't usually do this!"

"Enslaved friends do," Lisa said.

Her fingers brushed along the mouth of Stacy's sex. Stacy's closed her eyes, a soft moan escaped the back of her throat at the feeling. Lisa kissed her again, her free hand moving to her chest. The skin there felt soft and pleasant, her nipples were hardened and engorged. Stacy gasped as Lisa started to fumble with them. Awkwardly at first, but then with more skill as she read what made her friend feel the best way.

Lisa didn't start to finger Stacy. She didn't just dive right into her sex. Instead, she started to rub her pussy, moving her fingers in rapid, circular motions. The feeling made Stacy's legs go weak, especially when she felt Lisa's fingers move close to her clit.

"Oh fuck, oh fuck..." She moaned, her words getting faster and faster as her arousal grew.

Lisa didn't touch her clit directly. She knew that could be intense, and probably wasn't something that Stacy was ready for right now. Instead, she gently circled the area around it with her finger. Stroking and teasing the folds of Stacy's pussy with her other. Her friend was breathing heavily, soft moans coming from her with each touch.

"You have to do me as well, remember?" Lisa whispered. Stacy whimpered, but nodded. It felt very strange for Lisa to be opening her legs, standing with her thighs parted so as to allow her best friend access to her sex. She'd never thought about doing this sort of thing with Stacy before. It had never even come up in her fantasies. Stacy had always been her best friend, nothing else. Yet now, they were masturbating one another for a camera that never of them could see. It made her flush red with shame, but also intensified the burning desire between her legs. She swallowed, feeling Stacy's hand sweeping down towards her own pussy.

The two fondled one another like that. Lisa's hand moving in circles, somethings faster and sometimes more slowly. Meanwhile, Stacy opted for a more direct approach. Lisa felt her fingers start to peel aside her folds. Sinking into her pussy with and coiling inside of him. It made her legs go weak, and made her cry out in desire. Stacy's fingers were inside of her. Stacy could feel her wetness, her arousal. There was no hiding anything now, but instead of feeling bad about it, it only made her more horny.

Suddenly, Stacy went low. Her mouth opened, and her tongue lapped at Lisa's breast. Lisa gasped, Stacy's mouth started to suck on her nipple, teasing it and gently stimulating it. Lisa's back bucked, and she moaned more loudly this time. Her hand started to move faster, pleasuring her friend more intensely now. Stacy's fingers were moving back and forth inside of her, making it hard for her to stand. She was gasping. The feeling of Stacy's teeth grinding gently against her engorged nipple made her tremble. She gasped and moaned, spreading her legs wider to allow her friend better access.

Meanwhile, Diana was sucking off the machine. She could not look around, but she could hear the moans and the cries. Her pussy was splayed, arousal flushing through her. Her labia were engorged, pressing open to reveal her inner sex. The device was pressed right up against her skin, crackling and hissing as it responded to the motions of her mouth and tongue. It created a constant stream of pleasure. A feeling of tingling ecstasy which seemed to spread slowly across her body. Her skin felt hot, her womanhood felt tight, aching to be filled. It was embarrassing how well she was responding to this, sucking off a machine to the sounds of her sister and friend getting off.

Surprisingly - or perhaps not so surprisingly - it was Lisa who came first. She gave a soft cry which echoed through the room, throwing her head back in obvious pleasure. A moment later, Stacy climaxed as well. Her moans were deeper as the ecstasy flooded her body.
