Excerpt;She smiled and took my cock back into her mouth and it wasn’t long before I shot a load of cum into her throat. She swallowed it all and licked her lips, before saying that I was going to have to get used to the sight of her swallowing cum, not always mine though. My dick stood straight back up like a flagpole!We didn’t talk about it again until the next day, while we were watching a porno flick that Sarah had borrowed from a friend at work. The female star had just had an argument with her boyfriend and had decided to rush out of the house in a mood. She happened to come across three men in the local park, all of who were jogging in just shorts and trainers. It was no surprise when the three of them started to strip her naked and fuck every hole she had available! Sarah was sat with her legs spread wide apart and her finger rubbing her clit furiously when she smirked at me and told me to watch the film closely as I could learn from it. Unsure of what she meant, she warned me that the first sign of an argument between us would see her on her back in the park with three cocks in her. I was on her like a shot, kneeling between her legs and rubbing my cock against the entrance to her wet slit. I thrust myself forward and my dick rammed into her with ease, her pussy wet enough to take anything at that moment! I fucked her pussy like crazy for only a few seconds before I was pumping my cum into her, a look of amusement spreading across her face.What are you smirking at? I asked, breathlessly.You must be really turned on to come THAT quickly, she said, one eyebrow raised quizically.I am, I replied.I suppose this is as good a time as any to tell you, then, she said, a tone of uncertainty in her voice.What?I was thinking that we should go to that club in town, the one where…well, you know, she said, nervously.Which club? I asked, already knowing the answer.The Underground. The club where you can virtually have sex on the dance floor and no-one says a thing to stop you.The Underground was a notorious club, located in a back street, mainly to prevent the authorities closing it down, the theory being that if it was hidden from public view, then it wouldn’t offend. It was almost like a brothel, only you didn’t have to pay for sex because you did it with the person you went in with. If you took you girlfriend in, you fucked her. If you took the woman you were having an affair with, you fucked her. If you took your mother in…well, you get the picture. It was anything goes, and from what I had heard, anything usually DID go. I had never been in the Underground, but it was apparently true that people just sat down in a corner and fucked. If you still had your clothes on after 30 minutes, the other club goers thought you were either the police or the press. It really was an amazing place.I want us to go there and just see what happens, she said, breaking into my vision of a Roman orgy on the dance floor of the club.When? I asked, my mouth feeling dry with a mixture of apprehension and excitement.Saturday, she replied. I’ve been thinking about it all day. I want to go there and fuck somebody right in front of you. I want you to watch me fuck another man and all the time I’ll know that you’re loving every minute of it.Okay. Saturday, I said. She reached down between her legs and took my cock out from her pussy, before dipping her finger inside her and bringing it up to her mouth, slowly sucking it until the cocktail of my cream and her juices had been cleaned off. I hope you enjoyed that frantic fucking you’ve just given me, because it’s the last fucking I’ll be having until Saturday night…but it won’t be you who’s doing it to me!Oh, stop it. I begged. My dick’s still getting over that orgasm I’ve just had, don’t go teasing me and making me hard all over again.You’d better get used to me teasing you, lover boy, ‘cause I’m going to be doing lots of it between now and your next orgasm!I couldn’t wait to see what Saturday would bring!!Over the course of the next few days, I found out that my girlfriend was true to her word. It was the last fucking I gave her before Saturday night. I spent all week trying to get into her pants without success. Our sex life was incredible for the whole week…she had orgasm after orgasm and I didn’t get a single one. She had asked me on the Monday night if I would play along with her little idea for that week and I had agreed. She thought that it would put us in just the right mood for our Saturday night exploits if we spent the entire week practising. So every night, we ended up having hot and horny sex without my dick ever getting the release it so desperately needed. She would tease me and turn me on until I couldn’t take any more.
