I went into their room and turned on the blue light and changed myself into dad put on one of his suits and his spare credit card out the draw as I, ve used the card before for him I knew the pin number I sneaked down the stairs and quietly let myself out the back door then walked around the house to the front door and entered the house mum name Katy and was she excited to see me and smothered me with kisses she asked where was my car so I explained I had a puncher and it would not be ready until tomorrow so we would use her car tonight .I said I, m all ready as I took a good suit to work and also showered there Katy grabbed her handbag and my hand and pulled me to her car She gave me the keys and said you drive round the passenger side I went and helped her in the car she laughter and most unladen like opened legs wide to show me her panties and said just to keep you interested We went to a lovely restaurant Katy really enjoyed it and had 4 or 5 drinks ,About 10 we left after a fine meal when we arrived home we went up to our room with a Katy in the room she undressed to her panties and bra and come on lover off with that suit and shirtWhat do I do she was so happy did not want toupee herUp to then I did not know dad was so well hung now his cock was about 10 ins and really thick Katy made my mind up she grabbed hold of it tried to give me a blowjob then she s shouted I want it in me and pulled on top of her my God I lined it up with a very wet pussy and pushed much to my surprise it slid in l pound her it was fantastic .Then she said don t cum in me I ve been of the pill for at least10 days it was so wonderful I just could not stop and let a hugh amount of enter womb that was lovely she said but you know it is the worst time of the month to fill me up I then went back to my room and changed back to myself and wondered what mum would tell dad
