Very hot encounter with my unsuspecting sis
Ok this happened a few days ago while my sister was taking a shower. Pretty much for her to get into her bathroom she has to go through my computer room first meaning if she needs anything (toilet paper, soap, etc.) she just asks me to throw it in there for her.
Well the other day she was in her shower and the water stopped running and I heard her get out and start washing her face and such. Turns out she forgot a towel in her room so she yelled for me to go to get it. I went to her room grabbed it and ran back, I opened the door enough to fit the towel in. Well the bathroom is set up so there is one big mirror on one wall and the door is on the end of the room.
As I opened the door I casually looked at the mirror and saw my sis standing at the sink completely naked (since I saw it through the mirror I saw her front) I saw her tits (34B) bouncing around since she was moving her hands and chest a lot and her brown nipples and her pussy with a little bush around it. It was the hottest thing I had seen so I instantly got hard and had to go stroke my now throbbing cock. I could hear her from my room while I was sprawled on my bed stroking my cock. She was moaning a little so that just made me cum quicker. I don't think I will ever look at my sis the same way again. I'm hoping to let her catch me one day and see what she does but that might be a different story. Happy jacking!
