Brother and Sister_(3)

I must admit I love to jerk off. I’d usually do it in my room with the door locked sometimes sitting up on my bed my hand wrapped around my throbbing shaft stroking it or occasionally laying on the bed and just rubbing myself against the bed until I felt my hot cum escape my shaft.
One particular day I was home alone or so I thought I was. My door was closed and I had stripped down to nothing. Looking at myself in the mirror I couldn’t resist touching myself and soon I found my self sitting on the bed watching myself as I stroked my shaft feeling my heart racing in my chest.
I closed my eyes and licked my lips as my breathing got louder and louder as my climax approached in a deafening rush and I was rewarded with sticky cum on my hands.
I exhaled and opened my eyes and there she stood.
My sister was a year younger than I at sixteen. She had entered the room I figure in the heat of the moment and I didn’t hear here but that didn’t matter there she was.
