Join her in the water?

Christopher waded into the water. T'Pol watched him approach with a raised eyebrow. He moved until he was standing right in front of her.

"What are you doing?" she asked a little shakily. "I do not suggest..."

"Just relax," he interrupted and reached out a hand to cup her breast. She didn't pull away, but she again asked him what he was doing. "Just let me help."

T'Pol suddenly grabbed Christopher and pushed him backwards. He tripped and landed on his back in the water near the shore.

"You want to help me?!" she said menacingly, following him. Her amazing body came fully out of the water, and Christopher couldn't help but stare. She reached down and took his cock out of his shorts. Then she straddled him and Christopher moaned as she guided him into her. T'Pol held his arms down above his head, pinned just under the water and she rode him hard and fast. She was grunting and moaning as she slammed her ass up and down onto him, taking his cock deep into her pussy. The shallow water splashed and sprayed around them as she fucked him.

She was being very rough, and Christopher was on the point of becoming afraid when he came hard and deep inside her pussy. T'Pol yelled and arched her back and raised her face to the sky as he came in her and her whole body shook as she came hard on him.

After very lengthy orgasms, T'Pol pulled herself off Christopher and stared down at him as she tried to control her breathing. After a moment, she stood up and moved out of the water and into the tent.

It took a while for him to recover, but when he did Christopher went inside and found T'Pol sitting at the work table. She would not talk to him for some time. She was very cool and distant, even more than normal.

For the next few days, she asked Christopher to masturbate on his own outside, while she took care of her own urges. Eventually she discovered a mixture that would stave off the fever enough that they could remain in control. The Enterprise rescued them a few days later, and they briefed the Captain, who agreed the mission should remain secret.

T'Pol never talked to Christopher much after that except when absolutely necessary.
