My dad knocked at my bedroom door and came in. He was completely naked. I stared at him in surprise. Nothing like this had happened before and I didn't speak. I could see he was nervous. He took his little cock in his right hand and squeezed it in front of me and asked me if I was frightened. I said no and he asked if it was all right to stay. He sat cautiousliy on the bed and nodded to me to sit down beside him. He began to play with himself, looking at me and then at his hand playing with himself down there and then back at me and his cock got big. He asked me if I knew what masturbation was and I said it was wanking. Like what you're doing. He laughed and asked me if I'd wanked any boys. I did it to Billy, I said. Billy goes to the same school and my dad knows his dad. Dad asked if I would wank him. Only if you don't mind, sweetheart, he said. I asked him if it wouldn't be wrong. Only if you didn't want to do it and I made you, he told me. I didn't say anything in reply. He took my hand and put it on his chest and rubbed it against his hairy nipples. When I didn't resist, he began very slowly to guide my hand downwards to his lower belly. Is it all right, he asked. I smiled. He took my hand and placed it on his cock. I pulled back his foreskin and he let out a sigh and whispered urgently wank me, darling. I like touching it, I said. He lay down on his back and I masturbated him until he spurted all over my hand and his belly and thighs. I got him a box of tissues and wiped my fingers while he cleaned himself up. He kissed my forehead and said you did that beautifully, darling. Thank you so much. He got up to leave. At the door he turned, his cock shrunk back now into his hairiness. Our secret, he said and grinned.
