Alex from Exploited College Girls: one of my all-time-favourite scenes: super cute, sincerely inexperienced girl, shy and nervous but sweet and polite and agrees to everything she's asked to do.
I'd love to find more good scenes with exactly this feel: shy, cute, truly inexperienced girls, who don't look rough or down-and-out, and who look like they might regret having done the scene afterwards.
