Ned can't help it: he pulls away for a brief, amused, "I told you so." He can't help it; he likes Ginsberg's laugh, wants to encourage it in any way he can. There's something about the way he's holding himself that seems to Ned like a deliberate kind of relaxation, if there is such a thing. He's not tense, but he's holding the tension off through conscious effort - that's good enough for now. Ned can work with good weird.

So wraps his mouth around Ginsberg again, starts moving his finger back and forth inside him gingerly, letting him get used to the friction, the pressure. When Ned thinks he's ready - and he probably has been for a while, but he's being extra cautious, since the last thing he wants is to mess this up now - he adds a second finger, hooking both and trying to find an angle that seems to work for Ginsberg.
