I got down on my knees and slid his underwear down to reveal a thick and long cock.He helped me by completely removing his underwear and asked me to s...pit on his dick, lubricate it and then stroke him. I did so and began stroking his dick which was rock hard at that instant. After a few strokes seemed monstrous black and shiny. I had to spit a lot to lubricate such a big shaft.What followed was a long and continuing sex saga. I was getting bored that day. But not even in my wildest dreams had I. Quite a bit different to the attitude at home where sex was never spoken about and considered dirty. Pete drew me out a little more and discovered that I basically knew nothing about what my little prick was for or what girls looked like without clothes and that they had a couple of orifices purpose made for enjoyment. He then showed me some pictures in magazines of naked women that blew my mind and gave me a raging hard on, which in those days was referred to as being ‘on the bone’ Pete asked. I was hardly going to refuse this, so I groaned out a reply and the three of them laughed as Amber and Tina slid past each other. Tina wrapped her arms around my neck and kissed then whispered in my ear, “Fuck me well, dear! Let’s make them really jealous!!!” With that, she turned around and spreading her feet, bent over and I was afforded and incredible inviting sight of her shapely ass and hips perfectly presented for pounding! As I moved into position, Amber and Mom moved to either side of. Dont you no the masturbate?”I said,”mom what is masturbation?(As I have to say that or I can have a troublesome)She was shocked and said,” you don’t know.”I said,”no.”She said,”if you promise me you don’t tell dad I will do it for you.”I said,”OK mom.”She then my cock in her hand and spit on it.WOW it was like heaven.my Shalini look into my eyes,and started to stroke my cock.she said,”look into my eyes.”I looked and she was increasing.soon it get fully erect and it bulged to 6 inches.my mom.
