It was a summer's evening, July i remember well :-P, i'm heading toward the lunch-room for the dinner, my sister is sitting at the table and she wears...a tunic for the house and i see her from behind and, given the backrest of the chair was at half, i can see from behind her, and i see her beautiful ass tight inside that tunic, i don't know what kind and what size of panties she had because the tunic was of dark color blue blue-night :-P but anyway her buttocks they sink for well on the chair. .. I reckon we've both got problems, I just fucked my sisterwhile I'm dressed as a girl... At best it's weird, at worst it'sdownright illegal," I replied."Yes, Brother, I understand that but I'm not going to tell anyone. AreYou?" Nope," I agreed."Anyway, I've got an interview for a fantastic job on Friday morning andI'm meant to be opening the office on my own, Sally's on holiday andRoger is on a course all day. I applied really late I've tried torearrange but the interviewer is adamant it has. Saturday night wasn't so good because it turned into something of a gay/lesbian night. But Friday nights were when all the college students came out to party. Nation is a rave/freak dance club and it gets very wild on a Friday night.Jessica dressed up in a short skirt and a tube top with no bra. With her long tan thighs and fabulous ass, she looked stunning. We had slept in late that day because we knew we were going to be out late. We didn't even plan on arriving until 10 and the place doesn't. I looked over, checking if mom was watching me, when I caught the perfect image of my sister on the side mirror.Teresa was still squatting; her panties pulled half the way along her thighs. A car passed by, startling her, causing her to pull the short skirt over her ass. I chuckled silently at my stupid little sister. It was obvious she hadn't peed before outside her bathroom. I wished I could see the huge lake she had made on the road, if she needed all this time to pee.Suddenly she straitened.
