Him 'giving her' access to his wings was no small choice - he wanted pleasure and she's giving it to him freely as he works to build her tension and push her closer to climax.

Groaning his acknowledgement, his gratitude - knowing that the vibrations of that groan will work to push her further towards orgasm - is all part of his plan. (Granted: His plan is simply 'pleasure her', and fucking her with his mouth and tongue is a big part of that plan.)

He knows she is close, he can feel it in her muscles, so he reaches up one of his hands to take hers in his grasp, interlocking their fingers.

Together.
