 Click on the pic to see Bo getting fucked

44-year-old Bo wants to become a porn star. Thank fuck! The more horny MILFs that want to get fucked on film the better is what I say and Bo is certainly a fucking horny MILF alright.

She has brought that many change of clothes that we decided the best thing she could do is 3 changes throughout the shoot. The first outfit was a little nurses uniform, it hardly covered her pussy and tits, but hey - I aint complaining. She gave me great blowjobs and tit wanks while wearing that one.

The second outfit was her favourite porn bra and knickers, the chain mail design showed her tits off perfectly. More blowjobs were on offer and taken and I licked out her sweet, sweet pussy before she mounted me for a great fuck.

The last outfit was more conventional, tee shirt and skirt. I put my hand down her knickers and finger fucked Bo, which she enjoyed, then I stripped her before we fucked more.

I finished off this great shoot my depositing my load over her tits.

I have known Nicoletta for four years and never did a shoot with her. We talked about it often enough, we cammed and had phone sex, but never actually met up for a fuck.

I thought it was about time that should change, so we made arrangements for Nicoletta to come to my place.

I am so glad that she came. She was gagging for a fuck; she hadn't had one in ages. She dressed up in a little black dress with cut-out boob holes, that looked so fucking sexy, her big titties out on show. We kissed, she sucked my cock, I licked out her pussy and as we were doing 69 she squirted straight into my mouth, I swallowed the lot.

Nicoletta really enjoyed getting fucked, I enjoyed fucking her. We have agreed that we are going to meet up to fuck each other again.

Masie Dee put a posting on a forum looking for modelling work. She also wrote that she had the use of a stables where she keeps her horse. Now, as I love fucking outdoors, I was not going to give up the opportunity of fucking a delectable young girl like Masie in the great outdoors.

I sent her an email and arrangements were made for me and Tom, my cameraman, to go the stables. As it was a great summers day we decided to fuck outside, Masie told me that she had always wanted to get fucked outdoors and she was really turned on by the whole thing.

We both had a great time fucking each other, Masie loved it when I went down on her, licking out her sweet, tight pussy. I loved it when I blew my load over her small titties.

This was the second time I got to fuck Kay. The first time I did her was at her parents house, they had gone out and I went round and we fucked in the living room. This time, I went and picked her up from her parents place and brought her back to Derby to fuck her.

She is a great fuck and really loves sex. Her blowjobs are brilliant and she loves getting licked out. She gets really wet too when she is getting fucked.

Kay told me that a couple of months ago she started escorting, she advertised on a website and had a couple of meets with punters. She would like to do more as she cant get enough sex.

Dee emailed me and asked if she could do a video. She explained that her boyfriend is a member of UK Girls Downloads and he had always fancied seeing Dee appear on the site.

The photographs of herself that she sent convinced me that she would be perfect to do a shoot with. Tom and I were soon on our way down south to Dees' house.

She asked if it was OK for her boyfriend to watch her getting fucked by me, no problems there, as long as I can fuck girls anyone can look.

Dee was one of the best fucks I have ever had, she is a great kisser and when she started sucking my cock, it took all my concentration not to blow my load straight into her mouth. I loved licking her out and she told me that she did cum while she was on top of me - she has said that you should look out for the scene where her pussy lips are clamping on my cock, that is where she orgasmed.

I seriously do want to do another shoot with Dee - and soon!!

 Click on the pic to see Cheryl getting fucked

Cheryl is another first timer that I got to fuck on camera. Her boyfriend is a member of my site, UK Girls Downloads, and he and Cheryl were looking at it one evening when Cheryl said that she would like to get fucked by me.

Her boyfriend sent me an email telling me this and he enclosed some pics of her that he had taken. That was enough for me to make a booking. Soon, Tom, my cameraman, and I were on our way to Wolverhampton where they live. Her boyfriend works and could not get the time off to stay with Cheryl, he did want to see her getting fucked by me.

Cheryl is 19 and so fucking sexy, she loves her clit being played with so I spent plenty of time fingering, licking and rubbing her pussy, she really enjoyed that.

I got to fuck her bareback and we had a great time making this film.

Afterwards, Cheryl asked if we could do another one, this time, when her boyfriend has time of work so that he can watch. No problems there!

 Click on the pic to see Rayne getting fucked

This is Raynes' only porn video. She wanted to be a porn star since she was 16 and contacted a guy who runs a model agency, but was gutted to find out that she had to be 18. She then lost the phone number for the guy until she was 20. I saw Rayne on the model agency website, contacted her and she came to my place the next day.

She adores sex and loves getting fucked. I had a great time with her, she loves sucking cock and I love going down on pussy, which she liked having done to her. Her pussy got real wet as I fucked her and nothing was faked as we fucked. I nearly shot my load inside her a few times, though she said it didn't matter if I did, I did manage to hang on and shoot my load over her.

She loved getting fucked and has asked if she can come back for more.

We have fucked off camera since this shoot, Rayne has said that she stopped doing vids coz her dad found out what she was doing, but she loves getting fucked by older men so we meet occasionally to play together.

 Click on the pic to see Kim getting fucked

A friend of mine phoned me and said that he had met a girl who wanted to star in a porn movie. He wanted to fuck her and so did I, so when we all met up we agreed that Paul would fuck Kim first and then I would fuck her afterwards and we would film each other.

Kim was such a good fuck. She loves getting her pussy pounded hard, she gets so wet.

When Kim was getting ready for the video shoot, I filmed her getting ready. I got a hard-on watching her strip and change into her other clothes. I told her that watching her made me hard, so she helped me out by giving me a blowjob. I couldn't wait to fuck her.

Paul fucked her first and quickly shot his load over her back and then I fucked her. I pulled out just in time; I shot my load over her arse.

I met Lala in a chatroom I told her about my website, UK Girls Downloads and she told me that she was a pornstar and had done quite a few shoots. Now I prefer to be filmed fucking amateurs, but Lala looked so fucking hot that I booked her to come to Derby to do a shoot with me.

She sure is sex on legs. She has the sweetest tasting pussy that I have ever licked out; I loved it when I swallowed her juices. She also had a great pair of tits that I enjoyed sucking and licking on and she gave great head!

I had a great time fucking Lala and I shot my load of her tummy.

 I would love to fuck her again.

I met Pearl in a pub. I was out drinking with some mates when she came in with some friends. My mates got off with her friends and Pearl and I were left chatting to each other. We had a couple of drinks and I told Pearl about my website, UK Girls Downloads. She said that she had thought about doing porn, after all, she is at college and always needs the money, and she said working behind a bar was boring. I said that if she were to make a video with me, I would make it worth her while.

I gave her my phone number and told her to call me if she wanted to give it a go. The next morning she phoned me and said that she wanted to make a porn movie as soon as possible.

I went to her flat and picked her up. She said that she had never been fucked by a much older guy and was quite excited about it. I just wanted to fuck Pearl. I love fucking horny 18-year-old girls and Pearl was no exception. She is a chubby girl and well up for a good fuck. I enjoyed her sucking my cock and then I licked her out, before fucking her and shooting my load over her belly.

Pearl sure was a good fuck.

I met Cilla at the swingers club I go to. We had a real good fuck that night and I told Cilla and her husband, who was at the club with her, about my website, UK Girls Downloads.

Cilla said that she had done a few amateur hardcore films and that she enjoyed making them. I asked if she would like to star in one with me, and she said yes. The following weekend Cilla and her husband drove down from North Wales to my place.

Tom the cameraman turned up and we got started. Cilla, Tom and me went upstairs while her husband stayed in the living room watching telly.

Cilla has a great pair of tits on her, large and very suckable. I kissed and licked her tits and nipples, and then she gave me a blowjob, that felt so good. I then went down on her, spreading her pussy lips and getting my tongue into her, tasting her juices.

We then fucked in various positions, she was a great fuck, and she really enjoyed herself as much as I did. I shot my load over her ample tits.

Julia Blu used to have her own website and was looking for guys to fuck her so that she could put the film on her site. Well, as I like fucking ladies of all ages, I contacted her and she agreed to come to my place to make a video with me. I'm glad that she did. She was a great fuck!

Juila Blu is a mature lady, and mature ladies sure know how to enjoy themselves. She had lovely big tits and a juicy pussy that required lots of attention. We started off kissing, and then Julia got her tits out so that I could start playing with them and kissing and licking them. She then gave me a blowjob; she was fucking great at that. I licked her pussy, which she enjoyed very much.

Julia was so turned on that she wanted Tom, the cameraman, to fuck her as well. Being a gentleman, Tom agreed to her request and fucked her good, shooting his load on her.

I really did enjoy fucking Julia and shot loads over her tits.

Julia has closed her website down now, I don't know why, but I am so glad that I was lucky enough to fuck her.

I had made a video with Kirsty a couple of years ago. It was a solo shoot, where she had stripped and played with herself. She said that he did not do porn films. Pity, I would have liked to have fucked her.

Luckily for me she phoned me not long back and said that she had given it some thought and that she would like to make a film with me and her, I couldn't believe my luck, I was going to get to fuck Kirsty. She was a glamour model in the 80's appearing in newspapers and magazines and she was fucking hot!!

I love fucking girls, especially horny MILF's. They sure know how to enjoy themselves, there aint no faking with these ladies, and Kirsty was no exception. She loves to wear basques and stockings. I love seeing MILf's wearing those; they look real sexy in them. Kirsty gave me a great blowjob and I returned the favour by licking out her sweet, juicy pussy. She was a good fuck and when I blew my load she swallowed the lot!

I met up with Kirsty a few times after the shoot and we fucked, but we did not film those, we just like fucking each other.

MILF Madison emailed me and asked if she could do a video for UK Girls Downloads starring her and her boyfriend Matt. I like to fuck the girls myself, well it is my hobby, but she said that she would do anal and she only lets her boyfriend fuck her up the arse, so I said that would be OK.

I film the girls getting ready, I like to watch them undressing and then putting on the clothes that they will wear for the shoot. I enjoyed watching Madison getting naked, she has lovely, firm tits. I got hard looking at her. She noticed my predicament and when I switched the camera off, she offered to give me a handjob and a quick suck. I did not hesitate in dropping my trousers. Madison sat on the bed and popped my cock in her mouth. She flicked her tongue round my bell-end and swallowed my cock all the way to my balls. She then jacked me off till I shot my load over her ample boobs. I only wish she had let me film it, but she said no to that. At least I got to blow my load over her tits.

 Madison cleaned the cum off herself and got dressed. We went downstairs where Matt was waiting and we made the film. They put on a great show, blowjobs and pussy licking, fucking in various positions. Madison did take Matt's cock up her arse, she really enjoyed it too.

They finished with Matt cumming in Madison's mouth and her swallowing the lot. A great film!

I met Bernie when I went to a swingers club in the North of England. When I told her about my website, UK Girls Downloads, she said that she had always wanted to be in a porn film.

Tom and I went to her house in Lincoln to do the shoot. Bernie was a bit nervous to start with, but soon got into it. I loved it when she gave me 'minty blowjobs'. She puts mints in her mouth and sucks on your cock!!

It was great licking out her pussy, she tasted great. I especially liked it when she came and I tasted her cum. We had a great fuck. We fucked in various positions. Bernie loved getting fucked from behind; she really got off on it.

I shot my load over her big tits. When we had finished, Tom went up the road to the pub and Bernie and me had another fuck. We have done another video as well, Bernie came to my house and we went up to the woods to make an outdoor film.

My mate Matt phoned me one evening to say that he had met a girl in a pub. He told her about my website UK Girls Downloads and that I am always looking for girls to fuck and film. This obviously had the desired effect, because she said that she wanted Matt to fuck her.

They both came to Derby and that is when I first met Paige, a stunning 21-year-old yummy mummy from London. I so wanted to fuck her, but she insisted that it was to be Matt that was to have her.  We got back to my place and they did a brilliant shoot for me, with Paige sucking and licking Matt's cock and Matt licking out Paige’s' sweet looking pussy. They fucked hard and fast, with Matt shooting his load over Paige’s' face.

I was so turned on watching Paige get fucked, that after he shoot I went upstairs and started jacking off. Paige caught me wanking and she was so horny after getting fucked by Matt, that she gave me a brilliant handjob, I wish I had filmed it, but I had left my camera downstairs. I finished off by wanking over her tits. She sucked my cock clean, bless her!

I met Martine online on a social networking site and when she found out that I ran a porn website she said that she would be up for making a video as she did some part time modelling.

She was brought to my house by her boyfriend, but he said that he didn’t want to watch Martine and I fucking, so he sat downstairs watching a film while we were upstairs.

I loved fucking Martine, it wasn't like doing a porn shoot, she really enjoyed herself and we kissed loads and then she sucked my cock and I licked out her sweet, sweet pussy, which she really enjoyed having done to her. We fucked liked boyfriend and girlfriend, I had a great time.

Martine really was a good fuck.

I saw Rose on an escorts website. She lives and works in Nottingham, which is not far from me. I contacted her and made a booking. She was such a good fuck; she enjoys having sex as often as possible.

After we had fucked, I told her about my website, UK Girls Downloads. She said that she would be up for doing a video with me. A couple of days later I was back at her place with Tom, my cameraman.

Rose is a very sexy 21 year old. I loved licking out her sweet pussy, she also enjoyed it. And she gives great blowjobs. As I fucked her doggystyle, she did cum. I shot my load over her tits.

Laura was the first girl I fucked on film. I had seen her on a few websites and she has starred in some porn films. I was very lucky to have fucked her, because when she came to my house she told me that she had met a new boyfriend and was stopping doing porn shoots.

Still, at least I was lucky enough to have had the pleasure in fucking her, I am such a lucky bastard, fucking all these young, horny girls. I must have the best job in the world.

Laura was no exception. She gave fucking brilliant head, taking my cock all the way to my balls and back up to my bell-end. Lovely!!

I loved fucking her, she was so responsive and her pussy was so wet. She moaned with pleasure every time I rammed my cock into her sweet, wet pussy.

I shot my load lots, all over her tits.

A mate phoned me one night and said that he had met a girl who wanted to star in a porn film. I told him to bring her to my house to see if she was up for it.

The next day they both turned up. Aimee told me that she had done a few amateur shoots but wanted to do a video shoot for a website. Well, she looked as fit as fuck, so I told her that I would film my mate and her having a fuck.

She changed into a little tartan skirt that showed her legs off perfectly. As usual, at this point I wanted to fuck her, but my mate was desperate to give her one.

Aimee sure could give brilliant blowjobs and my mate finger fucked her till she came. They then had a great fuck in loads of positions with him shooting his spunk on Aimee’s tits.

Barrbie has just started out in the adult industry and contacted me through my website, UK Girls Downloads to see if I would book her for a shoot. Arrangements were made for this 19 year old blonde babe to come to my place a few days later.

She sure is a sexy girl and a great fuck to boot, she enjoyed getting fucked by an older guy and the older guy (me!!) sure loved fucking her. She gave brilliant blowjobs while she fondled my balls and I loved going down on her pussy, getting my tongue deep inside.

It felt wonderful when I slipped my cock into her wet pussy and fucked her in loads of positions and when I deposited my load over her tits, I thought I was gonna explode.

Barrbie certainly will be back to get fucked by me again.

Alex is a beautiful 40 year old MILF from Chester who I met in a chatroom. She told me that she likes getting fucked by strangers and goes to swinging clubs with her husband.

We made arrangements to visit her at her house and have sex while Tom filmed us.

Alex has small tits with large nipples, all the better for sucking on. I liked that she kept her stockings on while we fucked, very sexy.

Alex loves to be bitten on her shoulder while she is being fucked - it really does turn her on. We had a great fuck and I shot my load over her. She has said that she loves being naked outdoors, so do I. We have decided that we will make an outdoor fuck film when the English weather does improve. I cant' wait to fuck Alex again. She is a very sexy lady indeed.

18 year old Sarah saw my website UK Girls Downloads, and sent me an email asking if she could star in a video with me. She loves getting fucked by older guys and I love fucking younger ladies, so it was not long till this horny girl was at my house.

Sarah sure knows how to suck cock, I loved it when she had mine in her mouth. I returned the favour by licking her out. She then said that she squirts - which she then did! She actually squirted into my mouth, the first time any girl has ever done that. It tasted good!

We fucked a lot , she even sucked off Tom, the cameraman, he shot his load on her face just like I did. Sarah was a really good fuck.

I saw Megan advertising herself as an amateur model on a website. Her pics gave me the horn so much that I had to wank off while looking at them. She looked so sexy that I wanted to fuck her so badly. I emailed her and she replied!!

She came to Derby a couple of days later. She looked sexier in real life than in her photos. As we were driving back to my house, Megan told me about the time she got fucked in a pub toilet by three guys and she liked it so much that she wants to get gangbanged more often.  She talked so fucking dirty that by the time we got back to my place I had a raging hard-on.

We ran upstairs so that she could change for the shoot. I got my cock out of my trousers and Megan dropped to her knees and gave me a blowjob. She then laid on the bed and I gave her a quick fuck. I so needed it.

 We then went and did the shoot. We kissed and stripped off and had a great fuck, no faking here. Megan and I really enjoyed ourselves, she came and so did I - all over her face. She sucked my cock clean.

I met Kimberley on an internet chatroom. I told her about my website, UK Girls Downloads and that I am always on the lookout for new girls to fuck and film. This obviously had the desired effect, because Kimberley said that she had always wanted to be in a porn film, but at the age of 35 she thought she was too old.

I explained to Kimberley that MILF's are very popular, mature ladies know how to enjoy themselves and us guys love to watch them getting fucked. And I just love fucking MILF's too.

 Kimberley explained that she was married and she wanted her husband to come with her on the day of the shoot. No problems, I explained, if he wanted he could watch Kimberley and I fucking, but he declined the offer. I have fucked quite a few married ladies , both on and off camera, while their husbands watch. It really turns the ladies on for some reason.

Anyway, Kimberley and her husband came to my house. He sat downstairs and watched TV, while Kimberley and I went upstairs with Tom, the cameraman.

Kimberley was great. We had an excellent bareback fuck, she gave great blowjobs and I licked out her sweet, sweet pussy. I loved being on top of her while she had her lovely, long legs in the air and I pounded her pussy, I nearly shot my load at that point, but I managed to hang on till I popped my cumshot straight into her mouth! Excellent.

Porsha sent me an email asking if she could star in a video with me. No problems. Me and Tom set off for Leicester where Porsha lives. When we got to her flat she asked if it was OK for her husband, Tom to watch her getting fucked by me. No problems. It was a real turn-on for her, she really got off on it. Tom sat quietly in a corner watching me fuck his wife. I enjoyed it too. Porsha is a good fuck, she does a real girlfriend experience. She loves getting fucked and her husband gets off on watching her getting fucked by other guys.

Porsha and I have kept in touch since making this video. She has asked me back so that I can fuck her again and give her a creampie. I will be visiting her soon!!

Lovely tits and and a great arse. She fucks good too! Georgina sucked Matts' cock and Matt licked out Georgina's pussy, then they got down to some serious fucking. Matt shot his load over Georgina's tits.

Candy Lee has started doing porn and I got a phone call from another producer who had just done a film with her to ask if I would book Candy Lee for a shoot. I was emailed a photo of her and I had her booked to come to Derby the next day!

Fit as fuck or what?

21 years old and a great ride, just what I like about this job. I'm 47 and fuck horny young girls like Candy Lee for a living. She loved having her pussy licked out before I fucked her bareback. I just managed to pull out of her before I shot my load on her. My cum dribbled down her pussy. One of these days I'm gonna give a girl a creampie!

38 years old, UK MILF Frankie came to Derby to make a movie with me. She has starred in Channel 4's documentary 'Diary of a porn virgin'.

I went to the train station to pick up Sarah Jane, but this being England the train was late!

When she eventually arrived, I couldn't help but stare at her boobs, she was wearing a tight top that showed them off perfectly. Sarah Jane noticed me staring and told me in quite a loud voice that they were still growing. Nearly everybody at the station turned for a look. I said that they looked lovely,most of the guys nodded in agreement. They would have been jealous of me if they knew that I was going to take this horny 19 year old back to my house and fuck her.

Kimmi wrote and asked if she could do a video with me as she wanted to be in a porn film, how could I refuse an offer like that from such a beautiful and horny girl? Kimmi is from Scotland but now lives in the West Midlands of England. She is a lap dancer and is actually a mother of two!! She was also a great fuck.

When we turned up at her house and she opened her door I almost shot my load there and then, she was wearing the shortest skirt that I had seen in ages. It was not long before we were in her bedroom and were fucking. I loved licking her sweet pussy and she sucked cock great. And when I slipped my cock into her pussy it felt wonderful!

I shot my load over her arse.

I filmed Kaicee Marie getting dressed, I was well chuffed when she showed me her thigh length boots that she was going to wear during the video shoot, I love fucking girls in boots!!

She was an excellent fuck, she gave brilliant blowjobs and loved having her pussy licked out. I nearly shot my load as I was fucking her doggy, but managed to hang on till the end. I gave her a creampie, shooting my spunk into her juicy pussy. It was great watching my cum dribbling out of her.

I'm deffo doing more creampie shots in future.

I met Holly at the swingers club that I go to. We had a fuck while her boyfriend watched us. I told her about my site, UK Girls Downloads, and she said that she did modelling as well as being a swinger.

We made arrangements that evening for me to go to their place to fuck her on film. Holly did ask if it was OK for her boyfriend to watch as we fucked, like I say, that is not a problem for me, I love fucking to an audience.

Holly was a fantastic fuck. Slim, big tits, tight pussy. Even when we took a break from filming, Holly sat beside me, playing with my balls as she wanked me. I really enjoyed having sex with Holly.

It was Julie who contacted me and asked if she was suitable to do a shoot with. Suitable? She is perfect. A beautiful MILF who really wants to get into the porn industry.

We made arrangements for Julie to come to my house to get fucked. When she did arrive, she looked more beautiful than she did in the photos she sent me.

I enjoyed watching and filming Julie getting ready for the shoot.

We both had a great time making the film. Julie was a little nervous to start with, after all, it was her first video shoot, but she soon relaxed and enjoyed me fucking her bareback. She told me that she loves getting fucked.

I shot my load into Julie's mouth, it was a great relief depositing my load on her, Julie liked taking my spunk.

We must get together again and have another fuck.

Another girl I met on the internet. I had been chatting to Kay on MSN for over a year before I finally convinced her to do a video with me. She was worth the wait. She lives at home and said that I had to book an hotel room and pick her up from her place.

When I got to her place she said that her folks had gone out and would not be back for a couple of hours. We had to take advantage of the situation. It was quite exciting fucking a 20 year old girl, bareback, in her parents living room in the knowledge that they just might come back and find a guy who is old enough to be her dad fucking their daughter.

Kay found it exciting too and we both really had a great time. I certainly want to fuck her again, maybe at her parents place, maybe it will have to be an hotel. I might even try and get her to my place and see if she wants to stay for the night, then I could fuck her many times, but wherever I do fuck her one thing is for certain, I will cum inside her again like I did at her parents house.
