If they never had to wear clothes around each other, Q thinks he'd be perfectly fine with that. Unfortunately, clothing is heavily suggested by the general public, so their nudity has to be confined to one of their apartments.
By the time they reach the bed they're both naked, which suits Q just fine. He takes John's comment to mean that Q ought to be right there, as close as possible to John, as soon as possible, and he nods. "Agreed. Completely."
He twines his legs with John's and presses close, hands wandering down John's back, over his ass, stroking at his thighs as he seals their mouths together again.
