Spock lurched forward at the sudden cool touch, forehead pressing into Leonard's shoulder. It was automatic in that it hid how he closed his eyes, and he could breath the moan into his skin instead of the open air.

His mind couldn't help but point out the similarities to another situation, even in the heat of the moment. A hand wrapped around his cock, a low voice murmuring to him--

His hand fixed on Leonard's arm above the elbow. Tight at first, almost as if to move it away. Yet just as quickly as his mind had clicked to his memorizes and the building fear right at the edge of his thoughts, it argued against colouring this present picture. Simply feeling Leonard's bare hand and the buzz of pleasant thoughts was enough to sway him. This was allowed. Nyota was right there with him. He could enjoy this; Leonard wanted him to enjoy this. He could give and take pleasure as he wanted, nothing forced, and everything--comfortable.

Comfortable as in security, reassurance, trust. He trusted Nyota and Jim. He had trusted Leonard implicitly as a fellow officer and a doctor, but this was--he trusted him like the other two. Enough to allow him to touch and see and taste and hear when he wasn't in complete control of himself.

Spock's grip loosened, now simply resting against the skin. His hips thrust forward a little, seeking friction from Leonard's hand and the basic, physical pleasure it would bring.

If you believe I am hot in your hand, Almost teasing, if not clouded by a fog of lust. Imagine what I may be around you.
