Spock’s hand shook as he pressed his fingers to Kirk’s psi points. He had no particular plan. Just putting together a thought as coherent as “I should try a mind meld” had taken some doing. “My…mind to…your mind…” He grit his teeth. It was a bit like pushing a shuttle up a hill by himself while working quantum equations in his head. The real trick to it was putting himself in Kirk’s mind while retaining his own defenses against the psionic field. “My thoughts…to your thoughts…”
He didn’t enter Kirk’s mind, so much as fall into it. But it was chaos. He could make no sense of it; cacophonous sounds, images, memories, text, emotions, thoughts, all a tempest endlessly whirling in a void.
Adult, SNW, post-Subspace Rhapsody. Due to an accident Kirk ends up in Spock’s mind, intimacy ensues. This is simply lovely, full of emotions, sexual tension and bonding.
