When we moved into our first house, before we were married, we were given a large, probably a magnum, bottle of champagne. We drank it between us one evening so we were pretty pissed. When it was empty my wife stripped off, stood the bottle on the floor and proceeded to squat over it. She then lowered herself onto it and eased as much of it into her cunt as she could. I had never seen her do anything so sexy or filthy before, maybe a sign of things to come. She bobbed up and down on it, and I watched, cock in hand wanking, as her juices coated the bottle. She laid on her back with her legs spread wide and got me to fuck her with the bottle, seeing how much she could take. With each thrust into her cunt, she would moan and ask for more. I watched as her cunt lips stretched around the neck of the bottle, which was covered in her creamy fluid. I could tell she was near to orgasm and withdrew the bottle, just teasing her clit with it. She screamed for me to fuck her, so I thrust the bottle hard and as far as it would go into her and held it there while she violently orgasmed. I removed the bottle and replaced it with my by now rock-hard cock. She was pretty loose, from the bottle, and sopping wet, so I could hardly feel anything, but in my state of extreme arousal, I soon came in her. We kept the bottle and I think we did fuck her with it again.
What it did do was give her a desire to have her cunt stretched or filled. We experimented with a largish dildo that probed the depths of her cunt, which on removal was coated in what a female friend of mine, called “cunt butter” which was very much a delicacy. But the dildo didn’t do it for her, she preferred width or girth over length, so instead we tried to see how much of a well lubricated hand I could get in her. I would start with a couple of fingers and add one at a time, each time she would ask how many, then ask for more. I added a thumb, again she asked how many, and to keep going. Then my whole hand and I would gently stretch her, again she asks, and I say my hand, she says she can’t take it, but her greedy cunt sucks my hand in some more. I would move my hand in and out just at the point of maximum stretch, the sensation of stretching, relaxing, stretching her cunt repeatedly would cause her to have a strong orgasm. We would repeat the fisting and orgasm as many times as she wanted, until she was exhausted, but by then her cunt would be too loose for fucking, so I would wank and cum into her gaping pussy.
