With his head that close to Carla's exposed pelvis and crotch, the young man had the opportunity to get his first good look at the details of female genitalia-and found them lovely, to his surprise. Carla's bush wasn't as large or thick as his, making it possible for him to see the surface of her mons; with her sitting the way she was, he didn't have any trouble identifying the small bump at the top of her slightly parted cleft as being her clitoris. Flowing down from it were her inner lips, thin and small and looking incredibly soft. At the bottom, between them, he could see the entrance to her vagina; with her legs spread the way they were, she was opened up enough for him to make out what looked like a small ring inside her. Thinking back to some of the diagrams he'd seen, it took him only a moment to understand that that ring was her hymen… the maidenhead that defined her virginity. The entire area around her opening looked shiny to him, though he didn't know the significance of it until he heard one of the other men exclaim "Hey, it looks like missy's already worked up a little bit!"

Recalling the disappointment he'd seen on Carla's face (and what she'd done after he'd cum in her mouth), it dawned on Robert that his sister might be glad about what they were doing the same way (and for the same reasons) he was. Awakened to the possibility that Carla wasn't a completely unwilling participant, the young man silently resolved to do as much for her as she'd done for him.

After mentally reviewing the little bit of factual information he had about cunnilingus, he leaned forward; when his head got close to his sister's pelvis, he got his first whiff of a singularly enticing aroma.
