"Look, T'Pol," Christopher said. " I understand what you are going through, believe me. But you don't need to try and be the strong Vulcan. I think you need to relieve yourself too. You won't be any good to us if you can't concentrate."

T'Pol raised her eyebrow at this.

"You humans have a remarkable way of being up front," she said.

"I'm right though, aren't I?" he asked. "You need to keep your head as clear as possible. The only way I can see that happening is if you relieve the tension that's building up inside you. You need to orgasm."

T'Pol actually sighed a little. "I believe you make be correct."

She closed her eyes and soon her hands began to move along her flat, gleaming stomach. Soon a hand crept to a breast and she cupped it lightly over her wet undertop.
