I was a weak man, with a soft spot for beautiful women, in this case my own daughter. I was battling an addiction to her not unlike the one my wife ha... to her wine. But while I never sought out my vice, I still got drunk on the sight of her, when the opportunity presented itself.And it had presented itself tonight again.The sound of her soft, contented, humming had lured me to her bedroom. I had meant to ask what had made her so happy. I liked it when she shared her joys and college victories. Not one too argue with a lady, I started to pull out then push in, again and again and again. I was pushing deep and hard. There was a wonderful sound in the air, a slapping sucking noise, as my cock went in and out with my balls banging against her.Diane reached round with both her hands and parted her arse cheeks so I could go in deeper. All I could see was my cock pumping in and out of her pussy, while her anus was twitching. I got this really naughty thought and started to push my thumb. He grinned appreciatively and slowly began to run his hands up and down my sides, just following the shape of my body, staying well clear of direct causal contact with any of my more sensitive zones. As his fingers brushed the outside of my breasts I breathed in deeply and held it, trying to cause direct friction, but he was too wise to rush it and simply arched his fingers outwards a little, teasing me.The fingers of his left hand were soon playing with my hair as he sent butterfly kisses. For the first time during sex, I was able to just lay back and relax. I stuck my finger into her pussy, and started rubbing her Gspot, she began moaning and soon had an orgasm, then collapsed on me, and did not even remove my cock from her ass. I said "hey the condition goes away if I cant even cum in your ass honney, keep going. She giggled, and gave an odd smile, then got back up, and kept going. I put my finger back up her pussy, she tried to pull it out, she said "I dont think I can go.
