Her touch was electric and erotic, multiplying his lust more than she could ever know, really. He slid his finger in and out of her and slowly added a second.
He knew from their many intimate talks that she was a virgin and that if things continued progressing that he would be her first. He knew he'd have to be careful, that he might hurt her. Bill wanted her to enjoy this, which was why he wanted to make her come at least once before he entered her.
He leaned his head down again, sucking on her other nipple now, just intoxicated by the taste and touch of her.
