He decided she looked cute enough, and it could allow for some extra fun in the future if he stuck around long enough, so he decided to go for it. He walked up to the desk, before moving to the employees only door next to it.
Jeff opened the door, and walked through, turning right to see the backside of the reception desk. The girl was focusing on something on the computer, and didn't seem to be paying attention for people; Understandable, since it was the middle of the day, so most of those who would drop off their kids have already done so.
Without trying to necessarily be sneaky, but also not trying to get her attention, he walked up to her and kneeled down, analyzing the girl's body further. Rather petite, with a light bump on her chest indicating a pair of small breasts. Her dress went down far enough that he'd have to actually crawl under to check, but that also meant that she'd have a harder time resisting if she tried.
Being this close to a girl enhanced his erection, and he'd probably have to answer it soon. He tried to think what he wanted to do. He could just crawl into her mouth now, but if he wanted to access the more private areas, he'd have to climb into her clothes first.
