My Brother

Few nights ago I woke up in middle of night sudden. Found my brother in dark he'd pulled my pjs down and was stroking my clit with his finger. I pretended to sleep. I happens almost every night since then.. I guess it was happening for long too but I just found out. I enjoy it. But last night he did something weird he inserted something inside me .I think it was a pen or pencil he was moving it around slowly like trying to see how far it goes. I was so aroused trying to control myself that I peed a little . Now I can't stop thinking about it
