The scratches along Takumi's back, however unintentional caused an effect that Eira had no way to anticipate. During one such motion the lad's mouth closed around her nipple leading to a gentle bite that sent a shock wave of pleasure from the point up her spine. Her mouth fell open and the noise which escaped her was a combination of surprise and pleasure. "Ooooooo!~" This noise would come from her mouth before the sensation of the lad's tongue traveled up the full length from nipple to the side of her neck. Such was an amazing feeling for her as well and since his head was on the left side of her body she used her hand to touch his face her hand sliding back into his hair as she looked into his eyes in this moment. All the while her nether reacted to the constant stroking of their bodies together and worked towards an action which mimicked the one they would eventually delve into, but shied away from it just enough to make the anticipation build. It'd been doing so in such a steady manner that what fell from this woman's face as she found her first flourish and her body simultaneously tensed and relaxed was a plea for Takumi, which was made while looking him directly in the eye. "Aaaah!~ Takumi, please, I need you..." she practically begged for them to progress further than this, though she enjoyed it she needed more and she was quite sure he was ready too.
