He might've noticed the scars, had Sally not just revealed her breasts to him. Every thought in Harold's mind was blanked out but for admiring her chest. It was shocking he didn't pass out from the rush of blood away from his brain!
That moan as he ran his fingers over her was enough to remind him there was more to life than just Sally's boobs. He traced his fingers over her slick lips, feeling slightly out of his depth, but more than happy to try everything to see what made her make more of those noises. He slipped his middle finger gently into the wetness, tracing over her clitoris completely by chance, groaning as he did so. It was taking everything inside him not to come at the feel of her body. "Sal--god you're so hot," He whispered against her lips before kissing her again.
