Well, it's a start at least, and Jim lets out a pleased little sound when Spock tugs him along, managing to follow after without tripping over his own feet, and gladly falling to his knees without needing much prompting. As much as he enjoys having a smart answer at the tip of his tongue in situations like this one, all in all he's very pliant, easy, and for the lack of a better word, obedient.

He licks his lips while he hears Spock shift around just in front of him, curving them into a smile when finally the blindfold falls and he gets confirmation of their current positions. Which, for the record, he finds very pleasing and very promising both.

Slow breaths, Jim's knees shift on the floor, getting himself into a comfortable enough position as he sits back on his heels, dark eyes looking up Spock's figure, lingering on the bulge in his trousers, then up to finally lock their gazes together.

But before he can manage some smart little quip, Spock's tugging hard at his hair, teasing at the all too sensitive skin of his neck. He gasps audibly, barely managing to keep back a whine, his eyes fluttering closed as he licks his parted lips again, his Adam's apple bobbing as he swallows dry.

"I didn't... didn't remember," he answers honestly, and feels both sad and pleased that he did forget. If it gets Spock to react like this now, well... he can't say he minds the wait. At all. "I'm sorry. Didn't cross my mind— before."

Cracking his eyes open just a hint, he manages a crooked smile. Probably more teasing than it should be right now. "Better late than never?"
