Punishment and Reward

The chat continued to scroll, people talking excitedly as they tended to do when two cute girls were taking off their clothes. Lisa shot Diana a look, and the older sister managed a smile, even as she felt her heart hammering in her chest.

"Everything you ever wanted?" Lisa whispered with a grin.

"We'll see.." Diana answered.

The chat had slowed now, coming to a choice, it seemed. Diana's heart roared in her ears as she moved to the screen, wondering what she would be asked to do next. So far, it had been mild, but now that was about to change.

Challenge: Make the Other Climax, the Winner will be rewarded and the loser punished.

The words hung on the screen for a minute, and Diana felt herself go a little red. With her own sister? She felt mounting trepidation as she turned to look at Lisa, the shorter haired girl looking at her with the same sort of look. Really? Really?

Well, what did I expect? She wondered to herself. Of course we're going to be asked to kiss and to do other things as well... we're twins, this is what I wanted, wasn't it? I don't get a choice. I don't get to complain. I'm just here to do what I am told to do.

She felt her lower self stirring at the thought. The lips of her mound tingling slightly at the sense of helplessness. She was breathing deeply, her skin felt sensitive in that moment, her chest exposed to the world and to the camera. Lisa clearly felt the same way, the two twins locked eyes, shared a moment.

Lisa moved forwards, stepping towards Diana as the older sister rose. She felt her arousal mounting, her mouth drying, her heart hammering at the thought of everyone who was watching right then and there.

"How are we going to do this?" She asked, looking towards Lisa. The younger twin thought for a moment.

"We should make it fair." She said. "Hang on a sec, let's see what I can find here..."

She moved off to the far side of the room, where the toys were kept. Diana watched her go for a moment, and then turned her gaze back to the chat. She shivered, knowing what was coming next, both dreading and anticipating it. She felt her blood running hot through her body, her skin colouring as it pushed towards the surface. She felt no control at all in that moment, and loved it. It was what she had always been searching for, what she had always wanted to experience.

Lisa returned a moment later, holding something in her hands. A double-ended dildo of silicone, thick enough that Diana blanched slightly.

"This should do the trick." Lisa said. "One end each, the first to climax loses. You up for it?"

"Do I have a choice?" Diana asked.

"Probably not." Lisa laughed.

Her hands fell to the buttons of her jeans, undoing them slowly, feeling the tightness of the waist loosen and slack. She undid the zip next, then pushed the jeans down her long legs, feeling the fabric slowly sliding off her body. She kicked off her shoes, and then stood in only her panties, turning to face the camera, feeling a little thrill racing up her spine as she posed for them. Then, the panties went too, pulled down slowly inch by inch. Diana felt their flimsy protection sliding away, and clung tightly to it instant by instant. Her pussy was exposed by inches, the cold air rushing to brush against her skin. She suppressed a moan as she gently stroked herself, her fingers fumbling numbly at her lower self. Each touch was like a shot of heat that raced through her, making her screw her eyes shut.

Why does it feel so strong? Oh god, I've wanted to do something like this for all my life.

Feeling the weight of the camera on her naked body, Diana stroked herself, her fingers gently rubbing her labia, applying pressure just so, moving in a circular motion as she slowly drove up her passion. Soon enough, she could feel herself getting wet, her lower body tingled with desire and heat. She looked up to see that Lisa had kicked off her panties, tough still wore her dress, and was clad in two black tights. She lifted her dress, revealing her unshaven lower self to the camera and to her sister.

Diana licked her lips, once more unable to prevent herself comparing her sister's body to her own. As has been stated, the two were twins, but not identical twins. Though, they shared much, there were differences. Lisa's pussy was more delicate looking, with thinner outer lips, and a porcelain look to it of purity. Diana's was larger, her mound noticeably so, and her labia were thicker, as well as naturally parted slightly, revealing her arousal to the world. It was as though her own body had betrayed her, showing everyone just what she was feeling.

There were more differences too. Lisa's lower self was compact, not diminutive, but likely due to her history as someone into sports, her whole body had a sense of lithe functionality to it, like there was nothing there that was unneeded. Whereas, Diana's pussy was wider, more well defined. One could trace on her all the features of the female sex organ. She knew that sometimes, guys could have trouble finding the clit, but with her body, it had always been obvious.

She toyed with herself, her hands gently rubbing her folds, each touch sending spiking lust racing through her body. When she was sure she was wet enough, she stood up, and Lisa brought over the dildo. It was fairly long, large enough for them both to take and stand at the same time. Diana's breath caught in her throat as she felt the soft plastic, positioning one end of it directly over her entrance. Her other hand gently splayed her lower lips, and for a moment, she was wide open to the world.

_How many people are recording this? _She wondered. How many people are seeing me like this? If only they knew this side of me back home, how many would believe that the college ice queen was doing something like this?

She said none of that, however. Instead, she slowly drove the end of the dido into her body, feeling it press aside her folds, slowly filling her up. It was heavy, or felt that way, anyway, as soon as it started to enter her. She felt her mouth drying, her fingers clenched as more and more of it seemed to our into her. The soft play of it against her inner skin was torment, but soon enough, it had entered her as much as it was going to.

It felt strange to her, to have something like this between her legs. It felt heavy, an abnormal weight around her crotch. But at the same time, the sense of it filling her up made her want to roll her head back, to close her eyes and enjoy it. Her lower body felt afire with lust, her skin tingled, her nipples hardened.

Next, Lisa moved forwards, taking the other end of it and carefully directing it to her own pussy. She held herself open as her sister had done, and began to feed it into her lower mouth, slowly letting it fill her as well. Diana watched. Lisa's eyes were half closed, her mouth drawn into a cute pout as she focused on the feeling. Every few inches, she would stop, trying to master the rising feeling, before carrying on again.

A moment later, the two of them were ready, each of them having several inches of it inside of them. It felt strange now, more than it had before. The weight had vanished, but it moved according to the whims of another. Lisa felt Diana, and Diana felt Lisa. It was awkward as hell, and yet also somehow arousing.
