His eyes had been shut through those first touches of her hand on him again, the only sign of his reaction is his free hand gripping the sheets and the hand holding hers wrapping around her fingers more firmly. He breathes through his nose and bites his lip only to make a noise of surprise and try to sit up when he feels something definitely not her hand on him.

"Oh, kri-" his words are choked behind the moan he can't disguise as he falls back to the bed again. "What are you- kriff, that feels really good."

Of course he was sensitive there but that was before he'd ever felt her mouth sucking the head of his cock. He tries again to push himself up slightly just to watch her suck him off, his lips parted and eyes wide with surprise. Had he imagined her doing this very thing? Most definitely. Hadn't he done the same to her? Also true. That didn't stop his brain from coming to a complete screeching halt.
