A famous private school girl with little experience with men is stuck on a crowded bus on her way to school, unable to move, as her skirt flips up and her panties are exposed, but she can't fix it and is squirming. When I press my erect cock against her, her underdeveloped slit gets wet with shame and excitement. At first she shyly refuses, but when I insert it, she suppresses her voice and trembles as she has her first orgasm.
