Every so often she would bend over to pick up a rock or twig to examine and eventually throw at a nearby tree, but as she bent over I would get a nice...glimpse of her ass as her skirt rode up. She was doing it on purpose, and she was enjoying teasing me a lot I could tell. After she would bend over to pick something up she would glance back over her shoulder at me to make sure I enjoyed the sneak peak.

They looked down at me with utterscorn."Time for you to pop your cherry, brother dearest. I see your hard inyour silk prison, but you won't be needing this pathetic cock. No itstime for you to get fucked by a real man!"Stepping into. .. and when you have the sister hottie :-P (but anyway a good girl :-P), at a certain point i hear the voice of my sister from inside her room that she talks to the cellular and i don't know of who it was or a friend or a bf or a lover :-P, anyway seemed me that she was talking with a bf (a lucky boyhriend ... i thinked in that moment :-P) :-P, and so she was herself preparing for to go out also because she was saying it :-P, at least from what i had understood :-P, and therefore in that moment.
