Eric smiled at how Vala's responded even though she wouldn't be able to see his expression in the dark, and was very happy when he heard her admission. "I'm glad," he whispered back just as quietly.
He was doing his best to block out how Vala felt, but he still caught the echo of her pleasure in his mind, which served to heighten his own desire. He moved his hands to her thighs and gripped them tight enough to bruise, helping to hold her up while he slid most of the way out of her and then angled his hips up a bit and thrust in again. The rhythm that he set was deep but not particularly fast; he wanted her to feel him with each stroke in and out.
