Jerk off while watching her?

Christopher stood at the edge of the water, watching T'Pol. Her eyes were on him as she slowly began to play with herself just under the water. Her free hand cupped her breast again, squeezing it and pinching the erect nipple between her fingers. Christopher had never seen such a look on T'Pol's face before. Here eyes never left him and she had a look of intensity on her face that was part pleasure, part anxiety, and part lust. On the face of a gorgeous Vulcan, it was perhaps the sexiest thing he had ever seen.

He reached down and rubbed his hard cock over his shorts. T'Pol's eyes drifted down to watch him. Her hands stopped moving suddenly, and Christopher thought she was going to stop. But then she began to play with herself again, and Christopher pulled his cock out of his shorts and began to stroke it while watching her. Her eyes were fixed on him as he masturbated for her.

Her hand that was under the water touching her pussy, began to move a little faster and T'Pol began to move a little at the knees; bending slightly and rocking back and forth ever so slightly. Her breathing also intensified until Christopher was sure she was cumming. This set him off too, and he moaned loudly as a massive, intense orgasm overtook him. He shot stream after thick stream of cum into the water. He had never shot his jizz so far in his life. T'Pol actually moaned as she watched him and came hard.

After their long orgasms, T'Pol stood there, breathing heavily, one hand still caressing her breast. Finally she moved towards the shore and Christopher stared at her gorgeous, tanned and toned body as it came completely out of the water; droplets of liquid dripping off her smooth skin. Her pussy was neatly trimmed with fine, dark hair; her ass was sublime.

She stopped beside Christopher, so close that he could feel her heavy breathing. He waited, hoping she would touch his still hard cock, but instead she walked past him and into the tent without saying a word.

Christopher waited by the shore for a few minutes. Finally T'Pol came out of the tent, wearing her underclothes again. Her eyes still stole glances at his naked penis, but she seemed to have a bit of control back.

"It will be futile to attempt any further study of our original mission," she said. She was still trying to sound Vulcan and emotionless, but there was now a hint of shakiness to her voice. "However, I will still study the virus and attempt to find a cure."

She didn't look directly in his eyes as she spoke, and was also now avoiding looking at his cock.

"I suggest we relieve our tension at regular intervals," she said.
