Although she wasn't happy about what she'd been told to do, Carla wasn't what anyone could call disappointed about it, either: she'd been wondering what a real adult penis looked like, and although her brother wasn't quite an adult yet, he was certainly big enough-both in age and physical development. When she knelt down in front of him, she was getting an opportunity that she'd only dreamed about before then. Not daring to delay too long, she still took a few seconds to really LOOK at Robert's hard penis, it being both the first she'd ever been that close to and the first erection she'd seen.

Despite the circumstances, she couldn't help but feel a little thrilled by what she saw; after she got her hands on him, that thrill got even stronger. Raising the hand under his sack, she felt a mild surprise at how light it seemed in comparison to how big it looked; her tactile exam of its contents told her that his balls were generally shaped like the drawings she'd been shown in the Sex Ed class she'd had. Despite the gentle grip she had on his cock, she could still tell that it was incredibly hard underneath the smooth skin she was touching. Slightly awed by the size of it (her hand barely wrapped around it, and its width didn't extend even halfway down the length of it), she was amazed to realize that she wasn't afraid of the idea of something that big being inside her… knowing that a baby came out of the same place reassured her that the seeming monster she held would go in even easier.

Knowing what she had to do, Carla leaned forward and took a hesitant taste so she could prepare herself for actually having it in her mouth. Relieved to find that it didn't have any appreciable flavor, she did what she knew she had to and simply opened her mouth and took in what she could comfortably fit. She'd heard older girls talking amongst themselves, and read and heard enough other things to understand that "blowjob" was a misnomer; remembering what she'd already learned, she began putting it into practice and applied a gentle suction to the shaft that extended between her soft lips.
