sister

My sister is five and a half years older so would have been in her late teens. I’m not sure why I was going into her bedroom but none of the bedrooms had locks and we were not in the family habit of knocking before entering – but we were after this incident. I don’t even think the door was fully closed, as “wood in’t hole” as we used to say – I just pushed the door open. I wasn’t even looking where I was going until my sister shouted – probably “stop!” or “get out!” by the time I looked she had already folded her arms over her chest and started to turn away so I only saw her from the back, and her very nice bottom, BUT… as I backed out of the room I looked in the mirror and saw her pubes! Now this did give me an erection when I got back to my own room.
