Spock.
He was swamped, overwhelmed, drowning in feeling. He was so shocked by her unexpected touch it was several seconds before his activated his mental barriers and then it was like trying to block a high pressure hose by pushing his hand against the nozzle. Then the touch was gone the barriers slammed into place but by that time he was lost. He struggled to breathe. He was flowing and filled and overflowed. His knees buckled and he leaned on the desk. He was realised that what seemed at first to be on flood radiant emotion was made up of numerous finer strands of feeling and as each became clearer is was a small shock; he trembled. Through intense concentration he gained enough control to dismiss her. He must be alone. She brushed against him and he flinched. No more! He already overflowed he could not process the intense, overwhelming shocking load of feelings that had cascaded into him. His head lolling back as he fought for control. He felt that he had become insubstantial and that he shimmered and moved like a mirage. He ran his hand over this face and across his head as if trying to reassure himself he was as solid as always.
When he was in control of his body again he stood and left the lab. He walked slowly. He neither saw nor heard anything and his only goal was to get to his rooms and be alone. Fortunately at this hour no one was around and he reached the safety of his quarters without having to respond to anyone. He sank onto his bed and lay still feeling after shocks as the experience echoed through him. He knew he would need to mediate deeply to process what had happened. And what had happened? He needed to know. Cadet Uhura had always stood out from the other student due to her intelligence, ability and her beauty. But she was out of bounds, his student, and so he had not allowed his attraction to develop any further. He had known she smiled easily and laughed frequently and her anger was impressive, but he had no reason to believe she was a telepath. So what had just happened?
