I seduced my Father to have his way. At 17, my breasts were very perky and swollen, my hips became a little more curvy, and my bottom became round and tight. I was very vain about my figure and I used to examine it in the mirror because i knew what effect it was having on the males in my family. It was give them all erections, especially Dad! what a bulge! Sometimes I'd skip through the house in really skimpy clothing, and be the complete center of their attention, which made me smile and giggle. One day when just Dad and me were at home, and I had two hours until the boys returned, I got out a really tiny string mesh backless thong bikini, I had just bought, and put them on. I think Mum would be proud, if she could see it - the gaps in the mesh were just wide enough to sre everything I had right through it! it was so daring! I said "I'm going to sunbake out the back, Dad. Would you come out and rub suntan lotion on me? He groaned. I had been dangline my blossoming body right in front of him. Now I was asking him to put his hands all over me! I lay down on the towel on my front, so he could get started. He spread sun-tan oil all over my back, but stopped at the string above the bottom. I said "Do my bottom as well, Dad!" He said "You can reach it, can't you?" I replied "It's so nice just lying here. I want you to do it." He gave an almost-silent groan and began to massage all over my bottom and down my legs. I said "Hang on a minute, I'll just take my top off so I won't get strap marks. I sat up and faced him so he could see my swollen young tits and slowly peeled off the bikini top. He tried to look away, so I said "Do you think they need more sun, Daddy? He said"What?" I said "My tits. Do you think they need more sun?" He looked right at them and I could see the swelling bulge in his pants. He said "God you're beautiful. Then I turned around and went on my knees and hands, so that my bum was pointing right at him, and elevated close to his eyes. This position is called the doggy position in sex-books, and makes sex very easy. He was getting flushed in the cheeks fromt sexual arousal, and tugged at his pants a few times to make more room for his erection. He began massaging all over my bottom again. I knew he would be able to see how wet I wast getting. I spread my legs apart, openning my vagina to him. In a shaky voice I said to him "Rub me all over, Daddy. He said "If anyone ever found out... " I quickly reassured him. I'll never tell anyone Daddy. Daddy took off his pants. I said put it inside me, Daddy! I need you!" and we did it. I wouldn't normally write all these details to anyone, but I don't think any private details would disgust anyone reading this blog.
