“Yes, Sir,” she whispered.

He slowly walked around her. “I want to see what you look like when you’re coming endlessly, but still frustrated because your pussy is empty. I want to watch yourself grinding down trying to get the penetration. Once you’ve come enough...” He stopped at her side, looking up at her as he casually stroked and tugged her pussy lips. “And begged enough…then maybe I’ll switch to the dildo piece.”

He pointed to the box and from this height, she could see down into the case. Several other rectangular silicon skins rested inside. One had a curved dildo set on an angle, another had an oval bulk atop of short stock—probably a plug, and the last had two dildos for double penetration.

Now she understood what he meant by ride. She was going to ride this machine first without penetration, and then with it. She swallowed the urge to protest. To tell him that she wanted him inside her. His cock, his fingers. As long as it was him, and not some unfeeling toy.

Then he turned the machine on, and all protests and worries were forgotten. The Sybian vibrated far stronger than anything in her toy box. The nubs pressing against her still-sensitive clit were almost painful.

With a gasp, she sat up, putting space between herself and the machine. She just needed a moment.

A sharp sting to her breast had her opening eyes she closed only moments ago.

Andrei watched her with hard glittering eyes, a riding crop in one hand. She looked down at the faint pink spot on her breast where he’d struck her.

“You can wiggle and lean forward and back all you want, but you stay on. Your pussy stays in contact with the toy at all times. Next time you disobey and try and escape the scene, I’ll strike your nipple.”

Sofie whimpered low in her throat, though her pussy clenched at the idea. She wanted that. Wanted him to hurt her nipples.

“No, Angel. I won’t be gentle, it will hurt and pull you out of the orgasm unless you’re a very committed masochist.”

She nodded more in acknowledgment than agreement.

He studied her for a moment. "Arms up. Hands behind your head.”

She obeyed, only to curl forward with a cry when the crop landed hard on her left nipple. She had to dig her fingers into her own hair, pulling hard, to stop herself from reaching down to cover her now-throbbing nipple.

“Sit up," he said gently. “So I can punish your other nipple.”

With a whimper, she straightened. “I didn’t try and get away. I’m still on it.”

“I know, but I could see that the thought of having your nipples cropped wasn't a deterrent. I want to make sure you understand that when I intend to punish you, I will use more pain than is comfortable. True pain, not pleasure pain.”

Their gaze locked, held, and then she lowered hers. “I understand, Sir.”

“Good. Take a breath.”

She inhaled, held it, only to release the air as a scream when he cropped her right nipple even harder than he had the left.

This time, she didn't fold forward, instead keeping her position, her elbows up and spread wide, her breast entirely vulnerable. Fine trembles ran up and down her arms and legs, and her panting exhales contained soft pained noises.

“Well done,” he murmured, the praise helping dull some of the stinging pain. “Now you're going to be my good girl, aren't you?”

“Yes, Sir.” She swallowed and looked at him. “You’re not disappointed, are you?”

“Never,” he said fervently. “You’re beautiful. Perfect. Even if you lift that pretty pussy up again and again, until your nipples are red and raw from punishments earned, I won’t be disappointed.”

She relaxed at that, sinking down even harder onto the Sybian.

Andrei slid one hand into his pocket, and the machine turned on.

This time, she gritted her teeth, bracing herself for that first shock of pleasure. The nubs against her clit were perfectly spaced, one on either side. She wiggled until a third nudged the underside of her clit.

The sensation was so strong—a bone-deep rumble—she actually thought she wouldn’t be able to come from it, though this was pleasurable in and of itself.

Only a few minutes in, her body proved her wrong. The orgasm slammed through her, hard and sudden. There was no slow buildup, just a constant pleasure that turn into a muscle-clenching pleasure.

Sofie nearly tumbled off as the orgasm quaked through her. Andrei lunged to grab her just as she managed to reach down and grab the top piece of the horse. Now, she was leaning forward, which only pressed her clit harder against the vibrating panel. She felt the vibration not just on her skin, not just on the glans of her clit but all through her lower body. The deep parts of the clit, her vagina, her muscles low in her body—they were all rumbling with the vibration.
