I am not ashamed to admit that since my younger sister Tessa has turned four years old whenever I look at her I develop an instant erection which is clearly visible to anyone and when it’s just me and Tessa alone together I start by sitting in front of her rubbing and feeling the hard bulge in my trousers front then I next I get my c*** out and just play with myself pumping up and down harder and faster until I shoot my sticky b********* everywhere.
The thing is I am doing it more and more frequently and I am thinking about getting Tessa to toss me off too now
