Granny and Grandson

My room was next to the bathroom and long ago as my curiosity grew about what the other sex looked like in particular my grandmother and mother who were the only other two in the house besides me and the only women I had a lot of contact with looked like beneath their clothes I made a hole in my closet so I could look into the bathroom. The opening was in the blackened part of a painting in the bathroom and when not in use I could cover it so if the picture was removed it would look as if the wall was repaired. On my side I used silly putty to cover the hole and a poster of a basketball team.
Home from school one day I went to my room and full of pent up sexual tension began touching shaft then my head then massaging my balls. Soon my clothes were off and I lay on the bed my legs up and my hand rubbing my dick. That’s when I heard the door open and my grand mother announced she was home.
I swore under my breath because I was so close to cumming. Rolling out of bed I figured the best way to finish myself off was to go in the bathroom where I could gain some privacy and so I did.
Sitting on the toilet wit the lid down and my feet against the wall I first had to spur my dick back to the hardness it was before. Soon I was there again stroking away blissfully feeling the sensation building in my body until finally three contractions sent cum oozing over my head and onto my hands.
I continued to milk it until it stopped and cleaned up myself.
