Make her kneel

The strangers hands moved to her back and started to push Sarah forward. His knees coming together slightly, giving her an easy to slide to the edge of his lap.

“On your knees,” he orders.

The design of the bus didn’t give Sarah a lot of room. Naked and moving across his legs, Sarah was reminded that his dick was out and he was hard. It was average, nothing too impressive but nothing to be ashamed of either. It knocked her thighs and lower lips as she moved slowly towards the edge of his lap, earning a soft groan from him.

He opened his legs wider, as she reached the end, forcing Sarah to pick a knee to sit on.

“In between my knees.” Another order, one made with a smirk.

With little room to move Sarah had to quickly figure out a way to get down without drawing too much attention.

Sarah manages to keep her head low as she lowers herself to the ground. Despite her size, her breasts still get caught above the seat. Her body mostly wedged in place at this point. She tried not to think about; how dirty the floor felt; how corse the seat felt against her skin; the pressure of the cool plastic against her back from the other seat, keeping her from taking deep breaths.

It was then Sarah look how and saw the cock above her head. Looming a breath away from her face, over her, like it had power over her. It was almost as if she was helpless in its presence. In some twisted way; trapped in between the seats of the bus and made helpless but the threat of injuring her brother, she was.

It was then she realised what he wanted. She couldn’t decide if this was better for worse than whatever else he had planned. But, she’d never know.

“You look amazing down there,” he cackled, “but I think we should get started. You’ve had a lot of pleasure today. Always taking and never giving back.” He reached down and began stroking her hair. “So I think it’s time you learnt how to give back, hm?”

Using his free hand, he grabbed his cock and used it to tap her nose. As if teasing her with it.

“Now, open your mouth wide and do exactly what I say. Then you can put your clothes on, and we can go our own way.”
