I had been going out with my girlfriend for a little over four months. She had just started her final year at uni and I had just started my second year. I was always skint, yet Halley always seemed to have money as had her mate Tilly. The sex with Halley was fantastic, There didn't seem to be anything she wouldn't do or try. Tilly just seemed to flit from one man to the next. I couldn't understand how they always seemed to be flush with money. I decided to find out. Neither of them had a substantial job, they just tended a bar a few night of the week. I was sat with Halley and Tilly, so I asked Halley outright how come she always had money. She paused for a while, then told me she would tell me, but I would probably kick her into touch when I knew. I told her I would prefer to know, expecting it to be drugs or something else as bad. She took a deep breath then came right out with it, "Tilly and I do Porn films." I was shocked and not sure that I had heard right. "You and Tilly do porn films," I repeated, "Your porn stars. They told me yes. I sat there for a while trying to take it in. I knew Halley was no virgin when I met her, but a porn star. I had a thousand and one questions bombarding my mind. "How many films have you made?" I asked. "Well we don't make them we just perform in them and we have made eleven or twelve so far," Halley informed me. "So you have fucked eleven or twelve different men?" I asked. "More than that," she answered, " some films there could be just one man, but more often than not, there are five or six men and sometimes several women." Halley answered. "So you will have slept with between fifty and seventy men and some women." She was quick to answer yes. She answered dozens of questions, completely truthfully and eventually telling me that the next films were already scheduled. Then they asked would I like to be in it. I told them that I had never done anything like that or thought about it. Halley said that I was a good lover and had a big enough cock to do films. I slept on it that night. The next day Halley and Tilly were of for their STD tests and I went along with them. It turned out that they did bar work to pay for that tests. I had scraped up just enough for the test. It can take up to 14 days to get the test report back. All three of us were clear. The films were planned for the spring break and we were sent air tickets for Barcelona where the shoot was to be. We were met at the airport by a mini bus and along with two other girls and three boys were shuttled to a huge villa on the outskirts of Barcelona. On our arrival there was now five girls and including me eight men. It was late and after some food we all settled down for the night. There was the first surprise for me, there was just six bedrooms and thirteen people. Halley said that Tilly would be sleeping with us. I found myself between my girlfriend and her best mate. We were all nude and I got a hard on. Halley told me that I would need all my strength tomorrow and to ignore it and go to sleep. It was hard, but I did eventually get to sleep. Next morning there was a lot of commotion as cameramen, sound engineers, makeup and costume people were all setting up in the main lounge. Then the director turned up. He was instantly moaning as he had expected another female and two more men. He handed out scripts if that is what you could call them, The plot was basically that a mad professor built a gadget that could freeze time. He would freeze time and take advantage of the women present and grope and fuck them. Eventually he would unfreeze some of the men to also fuck the girls ending with an all out orgy. I was given the part of man no. 2, Halley was given the parts of girl 2 and girl no 5. She was going to get the most action and as Tilly pointed out the most money. Two scenes were set up one indoors and the other outdoors by the pool. I quickly realized that the scenes were not necessarily filmed in order. Scene one was the professor testing his gadget for the first time and girl one was Tilly and she froze as he clicked the device. Then he was waving his hand in her face and she stayed completely still, even when his hands scooped her tits out. He mauled them as she still stayed completely still. So his hand went up her skirt and into her panties. She still didn't move. He walked her to a couch and bent her over it and raised her skirt and pulled her panties down to her knees. Tilly was completely still, even when he took out an eight inch boner and slammed it into her fanny and screwed her until he was finished. He dressed himself and walked to the other end of the room and clicked the device. Tilly looked confused as she discovered herself disheveled with her panties around her knees and and her fanny full of spunk. The director shouted, " Cut that's a take." Tilly went off to clean herself up. Scene 7 was two of the other men watching Halley as she swam up and down the pool and as she got out and was on all fours we heard the clicking sound and all three were frozen and then two more clicks and the two men were now awake. The first one checked Halley out and found she was frozen and groped her tits. She was still frozen and he pointed it out to the other men and they took her tits out and one of them fingered her pussy. At this point I was getting a little jealous seeing my girlfriend getting fingered by another man. Then the first man put his cock in her mouth and was face fucking her. I had never watched someone else getting head and for a few minutes I was fascinated and then the second man slammed his cock into my girlfriend and gave her a pretty serious fucking. Then they swapped. Fortunately Scene 6 was called. That was me. I was reluctant to leave my girlfriend being used at both ends by two strangers. The director shouted again and I went indoors to the scene that had been set. I was meant to be at a bar along with another man. The over end of the bar was two girls, one of them was Tilly. I stood there and heard the click and then a second and third clicks. The other man made a beeline for the other woman, a pretty blond and I made my way to Tilly. we both groped their tits and then bending them over their bar stools fingered their fannies. Then the man high fived me and we swapped and I was groping the blond's tits as the other man groped Tilly's tits. Then he was first to start fingering Tilly's pussy and I followed suit fingering the blond's pussy. It was at this point that I realized that I had a hard on and it was uncomfortable. The over man was now fucking Tilly and my script said that I had to lick the fanny and arse of mine, so I did . They had to do retakes as she groaned several times. Then my cock was in a woman I had barely met the night before, fucking her brains out as the script informed me. I came in her and the camera took a close up as I withdrew and my spunk came out her fanny and run down her legs. Then the man and I were redressing and back to our bar stools. Then a further click and the girls looked stunned and confused that they were bent over with disheveled panties and full of cum. Halley caught up to me and asked was I ok. I told her I was , but I had been jealous when she was being face fucked and screwed. She laughed and said I was sweet and that I would get used to it There was another scene shot the other side of the pool area and then yet another indoor scene. This one again had Halley this time with the professor. All was going well and although a little jealous I was handling it until he stuffed his big eight inch cock into Halley's arse and arse fucked her. I had to walk away or I would have ended up hitting him for fucking my girls arse, something I had never done with her. Then everything stopped for lunch when a catering van turned up. The director seemed pleased. As I sat with Halley and Tilly eating lunch I asked Halley about being fucked in the arse. She said it wasn't her favorite thing but the money was better if you did anal. Note to me I thought, no amount of money will see someone stuffing his cock up my arse. After lunch there was a group scene and Tilly and I were in it. The scene was similar to all the others and the professor clicked the gadget several times and the men and the professor numbering seven men against four girls. They all groped tits and then pussies. I ended up with my cock in Tilly's mouth as the professor fucked her viciously hard. Then I was moved to another girl a small black girl and I was to fuck her. This was new for me I had never been with a black girl and although she couldn't move I thoroughly enjoyed fucking her tiny body and dropping my cum in her fanny. Halley was in another scene outside. Our scene with pauses and retakes took nearly three hours and then the food van returned and we broke for food. Halley and Tilly both seemed pleased with themselves as neither had retakes. After food the director called for one last scene for the day Again Halley was in it along with another girl, the black girl. The format was just the same and both of them had there tits groped before hands were in their panties and then they were face fucked and pussy fucked and the lads all revolved around until all of then had been sucked and fucked by all of them. Halley had a retake as she came at one point as one of the men was pounding her fanny particularly hard. Then we had the evening supper and after some Sangria everyone tucked in. I was too fucked to even get a hard on with my cock against Tilly's arse and Halley holding my balls. The following day was more of the same. I had by this time fucked all but one of the women and I think both Halley and Tilly had fucked every man, including Halley fucking the director between scenes. Then more sleep. The final day there was just two sacenes the first was the orgy scene. We had to finish before four p.m. to enable us to be back at the airport for our flight home. The men were rotated around the girls and I finally got to fuck the fifth girl along with three others. I was to arse fuck the black girl and I was careful not to hurt her, The director shouted at me to Fuck her and not tickle her. I ended up slamming her gorgeous black arse. I had my cock in every girls mouth at some time during the scene and ended up coming in Halley's pussy as did two other men during the scene, The final scene was Halley got the gadjet and after some experimenting fucked the professor and two of the men. The director shouted that it was a wrap. He handed out envelopes to all the performers and then we were in the mini bus heading for the airport. It wasn't untill we were in the airplane that I looked in the envelope. I had two thousand four hundred pounds. Tilly had Five thousand eight hundred pound and Hally had over eight thousand pounds. Talk about discrimination, men get far less than the girls. Never mind where else could I earn that much in just three days, and I have a girlfriend that encourages me to fuck other girls. Back home, Halley was sore for several days before she let me near her fanny, and then I had a wonderful threesome with Halley and Tilly. They tell me that the Christmas break is now planned and I will need my tests done if I am going with them. What miss out on shagging other girls with my girls permission. I still get jealous though. P.S. Halley let me fuck her arse.
