Watching Dad

I was in my first year at college i was at home pulling a sickie, i had to go to the bathroom when i was passing my parents room, dad was sat at his lap top he only had his PJ top on i could see he was watching porn mum had gone to work he obviously thought he was alone, he was holding his hard cock, i had seen dad nude before i did have thoughts about dad i knew were taboo and what he could do to me with his cock, he must have knew he was being watched he wanked his cock in front of me and said this is for you when your old enough, i was 15 i knew about sex and had given myself pleasure, now i am of legal age, how to bring it on
