I was invited into a couples home to "Just watch" and film them as they had quite a lot of home movies, but they wanted better camera angles. I did not mind as I was a straight single male at the time and thought this was a thing of fiction for single blokes to be invited in. All seemed fine we were just chatting having a few drinks and getting to know each other, when the wife said she wont be long. About 20 mins later she came back into the kitchen wearing the sexiest lingerie I have ever seen, and it complimented her stunning figure perfectly. Tony showed me the camera equipment he had which was very straight forward so we went into their large lounge where they wanted to play and film. To be perfectly honest I promised not to make a move on the wife which is why I was asked there, but seeing her I was so jealous of Tony. It was my first time filming someone else having sex, I had done this with my ex-wife but it was like making my own porno as they asked me to tell them what to do, so while he was doing all the things that I love to do to his wife it was going through my mind "I so wish that was me" I was quite shocked at their stamina as they were both in their early 50's but it was over an hour before they stopped for a break. When they started again Sue knew the affect she was having on me as the trousers I had on were stretching quite a bit. Whilst she was getting Tony hard again she just reached over to me, undid my zip and slid her hand in to my cock. She said to Tony "oh yes, we are definately playing with this one" and she got on her hands and knees in front of me, looked into the camera and took my cock into her mouth. Quite how I never exploded into her face I have no idea as she sure as hell knew how to use her mouth. Tony was now behind Sue and I was now in my first ever 3some and it felt really good as I expected. I had the best blow job ever off Sue. I have always been told that I am blessed in the cock and balls department, so had never had a good BJ before, until now !! Sue finished me off after less than 10 mins and I had never come so explosive before, even to my horror over Tony who had just come over Sues back, but he just laughed. We were back in the kitchen having a drink when they asked me what I was into and had I ever been with a man, which I had not. I had experimented at anal play in my teens but that was about it. After a few drinks Sue started playing with herself again and I was hard straight away, she took my hand and we went up to the bedroom where we caressed each other before I went down on her. Tony was now the one doing the filming, he did ask if I minded as he set up the tripod, to be honest I could not have cared if he was juggling monkeys as I was having a great time ! Sue laying on her back eased me up to I was sat astride her chest as she licked my skin between my balls and arse, then quite unexpectedly she pushed her tongue in my arse - it was the most amazing feeling ever, the veins on my cock were almost exploding as she pushed her tongue in and out, then she eased a finger in, then another. I was having my prostate massaged. I had read about this but as a straight man never thought about doing it ! but it was just unbelievable. Sue then said have you ever sucked a cock which I had not, so she said why not suck Tonys. I was a bit apprehensive but so fucking turned on by what she was doing to me that I took his cock in my hand and started playing with him. I then thought what harm can it do, so I leaned forward and just took him straight into my mouth, right down to his balls. I thought this may be hard, but he was no way as big as me so was really easy to suck his entire cock, especially as Sue was doing such a great job with mine. Sue told Tony to turn around and bend over, and said to me why dont you get him nice and wet. I panicked now as this held no appeal to me whatsoever, Licking a hairy arse actually made me feel ill so I was thinking about just getting up and saying enough is enough and leaving, but Sue must have sensed my apprehension so she slid up onto her hands and knees and started tonguing Tonys arse, at this time she said put that straight in there whilst easing her pussy open. She was so tight it was incredible, but as I had come twice already and been milked so well it was so nice to be in such a tight pussy and not come straight away. after a couple of minutes Sue eased forward so I slipped out of her and moved away to the the side of Tony, she eased his arse cheeks apart and said "Fuck him" I was so horny but had no wish to, but felt like who the hell will ever know, I may as well try it. So i stood on the bed behind Tony lowered myself as if squating and eased myself into his arse. I thought Sue was tight, this was even tighter. As I am so big down there I just kept it real slow and was only pushing in a couple of inches when Tony just pushed back onto me and my entire cock eased deep into him. The feeling was incredible and I could feel the tip of my cock rubbing against something that I thought must have been his kidney or liver !! after a couple of minutes of this I was ready to pop and Tony must have felt something as he leaned forward turned round and both Tony and Sue were sucking my balls and cock whilst fingering my arse. When I came it was that hard that it felt like marbles coming out my cock, but the feeling of euphoria I have never felt before, sue then turned on Tony and finished him off. I did help but the thought of another mans spunk in my mouth did not appeal, but this couple must have know that as they never pushed. My first experience of a 3some and my first time with a man is a memory that will stay with me forever. I stayed in touch with Tony and Sue for about 11 months before they moved to France for work, and although I never did anything with them again after that night, the memory of it has helped me out on more than one occasion.......
