The contrast between the cool metal of the ships hull against his bare back and the hot, moist mouth that was currently surrounding his cock was enough to drive him over the edge.

"River, what you doing? Your brother is going to come round dat corner any minit." Jayne almost squeaked when she pushed him against the ships hull and started to undo his pants.

"Simon is with Kaylee, won't come round this corner for 5.6 minutes. River wants to pleasure you before we go on the job." River explained. Tugging on his zipper pulling it down to expose his sizeable cock.

"River girl, stop it, what if Mal or one of the others comes round, don't ant any of 'em to catch us." Jayne moved to stop River but she took his hands and tied them to one of the polls surrounding them. "Planning this, were you baby girl?" He said smirking down at her from where he towered over her.

"Fantasy of River's, wants to know how quiet you can be while I make you cum." River said with a predatory smile on her face. Jayne almost winced when she finished taking off his trousers, hearing Mal walk towards Inara's shuttle.

She took his shaft in her hands as she started to stoke it up and down. Jayne started groaning as she continued her ministrations. She got on her knees in front of him and spat on his cock. She stroked it a few more times to get it stiff before she took it in her mouth.

The contrast between the cool metal of the ships hull against his bare back and the hot, most mouth that was currently surrounding his cock was enough to drive him over the edge.

He came powerfully as she started to hum around his cock. When she swallowed his cum she looked up into his eyes, glazed over and unfocused from his orgasm, and smiled.

"River pleasured you well?" she asked when he was coherent enough to understand.

"Geez baby girl, next time you do that make sure it's on my bunk so I can return the favour."
