The plea drives him to press that finger inside them slowly, mouth steadily taking in more of their length as he does so. His tongue swirls around the tip and flicks over the slit before flattening against the underside, and he bobs his head a little without taking too much of them in yet.

His finger is soon joined by another, and he hums around them before sliding down to take them deeper still. If he hadn't already finished, he knows he would have been desperate at this point... but luckily he can take as long as he likes with them. Whether or not Nimbus thinks that's a good thing is questionable, but he gets the feeling they'd rather get off sooner than later. So instead of drawing it out as long as possible, his fingers begin to press and pull backwards and forwards into them, slow thrusting movements accentuated by the way he pulls up and bobs his head again.
