Although boyfriends may come and go, the one constant in my life is Katie. We are both unpossesive bi-sexuals, and actively encourage each other to seek out new partners to either join us or just to share stories over later. One evening, we were together and, as we often do, surfing some of the less reputable parts of the internet, when we came across a web site for a model agency. It seemed that as well as the usual stuff, they also supplied models for porn shoots. We were soon on the pages of the male models, and admiring the pictures of all of the gorgeous studs, many of whome had their massive cocks prominently on display. After a while, I hafd a thought. If they are willing to screw on film, presumably it wouldn't be a problem for one to come round and attend to Katie and myself? So, we picked a guy calling himself Rocket, and sent the agency an email, saying that we would like to book him. A few days later we had a reply, and, to cut a long story short, we arranged to meet. We both travelled down to London, and arranged for him to come to our hotel, where we took him for a drink first. We told him to dress smartly, and he didn't disappoint. He was 26 years old, tanned, in a lovely designer suit. However, when he saw us, I thought he was going to die! I was wearing a favourite dress on mine, which I call "no knickers" as it is impossible to wear anything with it apart from shoes! It is black, and goes down to the floor. However, the left side is slit all the way up, way beyond the top of my leg while there is no back, and it reveals just the top of my bum. Meanwhile, Kaitie was in a little black mini dress, which displayed her boobs and legs perfectly. We spent an enjoyable hour with Rocket - we were surprised to learn that was not his real name, which was Alex! - chatting about our respective sex lives in the hotel bar, before we went for a bite to eat. The three of us looked incredibly gorgeous, and people were watching our every move. After dinner, we went back to our room. Katie and I lay on the bed, cuddling each other, and we asked him to strip naked. He underdressed superbly, until he finally revealed his massive cock. I love giving blow jobs, and I was straight down on him. However, there was no way that I was going to be able to get all of this in my mouth, and I teased him with my tongue, sometimes taking him in, other times just licking the side of his shaft. Meanwhile, Katie moved beside me, and started to slide her fingers gently in and out of my now moist sex. After a few minutes, Katie stopped, and stood up and performed an incredibly sexy striptease, until she ws naked apart from her stockings. Alex called her over, and as I returned to his prick, he started to fondle her boobs. He then pushed me away, as Katie lay down on her back on the bed. She gasped as he sunk his massive tool into her,and I moved to her face so that she could lick me out as Alex and I kissed. It didn't take long for Katie to come, and he moved off her, and told me to bend over a table. I knew what was coming, but even so, I wasn't ready for the shock of this huge cock entering me. It was amazing, as he just kept coming into me, seemingly never stopping. My cunt was totally stretched by him, the pain excruciating, the turn on phenomonal. Katie, meanwhile, moved behind him, and started to fondle his balls from behind. As I climaxed, he knew he was going to come, and made Katie and I lie on the bed, with our legs hanging over the side, and then he moved between us, filling us with his jiuice. All three of us collapsed onto the bed, and, although he was only booked for a few hours, he decided to stay the night, and we fucked again an hour or so later. We also ordered a blottle of champagne afte that from room service, and left Alex naked on the bed - the waiter was a sight to behold when he saw Alex's massive tool. The following day, I could barely walk. I allowed myself many a wry smile though at work when colleagues asked me what the problem was. If only they knew!
