His body trembled beneath her own, and when her voice as heard anew Grimm managed to make a sound...a faint moan and chuckle mixed together.
Through heavy lust laden eyes he gazed up at her for a moment, holding so still as he just marveled at the sight of the Doctor's golden hair being haloed with the living room light. At last his fingers finally moved a bit, slipping up beneath the hem of her shirt, nails gently raking up along her back. "Hard...not tense, Doc. You make me so fucking hard."
