Her senses were being fantastically overloaded again. It had been a long time since she had been made to feel this alive. Her hips bucked at his tongue while her chest arched into his hand. She couldn't hold back the pleased sounds he drew from her. She didn't want to. She wanted him to hear exactly what he was doing to her.
She shouldn't have looked down though. Making eye contact with John and seeing him wink along with the new sensations of his tongue within her was all too much for the Doctor. His name was on her lips again, a soft mantra that grew faster and louded as her second orgasm built.
This time when the walls came crashing down, the Doctor's back arched up and thighs tensed, momentarily increasing the pressure of his mouth on her and causing a small cry from her breathy lips. The world could have crumbled around them at that moment and the Doctor might not have noticed.
