it started some year ago, i was constantly telling my gf i wanted to watch her getting fucked by another guy, we had been going out for 6 years and had a very good sex life, all was good. we had started going out as couples with some friends, shed known them for years, Alan and Marie, she wasn't a big drinker so when we came home Marie would go to bed at hers and more often than not Alan would come to ours for more drinks. i noticed that he seemed to always be in our bedroom, even if it was obvious i had my cock inside Betty and was fucking her, after this went on for some weeks i said to Betty you know Alan wants to fuck you dont you, she dismissed it, i pointed out that he watches her getting fucked and doesn't leave. i pointed out that he follows us upstairs every week, i even said i bet he gets a hard on as its obvious im fucking you. she dismissed it over and over, i asked if shed let him, she said he wouldn't want to fuck her as Marie is stunning. i could tell by how wet she was it was turning her on. the following week same thing out till 3am drop Marie home then us 3 go to our house. Betty and i hadn't discussed Alans cock at all through that week, any way we get in more or less straight away Betty says im off to the toilet, and of she goes upstairs, not sure why but id put some porn on with the scenario being husband watches best friend fucking his wife after night out, just to push Alan further into trying it on with Betty, Alan was a snake and would fuck anything he could he was a nutter when he had to be so retribution wouldn't put him off, although we had become friends he wouldn't let that stop him, any way after Betty had been gone 10 mins and as far as he knew still on toilet he announced he was going to toilet, strange i thought but didn't say anything, off he went upstairs, mario account of next 45 mins i waiting 5 to 10 mins and decided that he wasn't on toilet he was upstairs fucking my gf, i didn't charge up to stop them if indeed that is what was happening, no i turned to tv down opened my jeans and opened door to stairs i stood there listening for the sound of my gf getting fucked , i was wanking my rock hard cock all this time, in total 45 mins went past and im sure i could her her moans of pleasure, as i heard alan coming back down stairs i went back in room and waited, he walked in with a grin that said ive just nailed your gf, he said to me betty need me to do something for her, i asked and did you give her it, he smiled and said yes i gave her everything she needed for a least a week,wen he went i went upstairs where Betty greeted me with well your were right, about what i said. she replied he does want to fuck me, how do you know i asked , i called him into our room and was laid back with me feet on side of bed when i said Alan mario keeps telling me that you want to fuck me, i asked and what did he say, he just stood there so i dropped my knees apart to reveal a shaven pussy no doubt shining with my pussy juice screaming i need your cock, as i opened my legs i just said well do you, it was plain i wanted his cock inside me,what did he do i asked she said he walked over and reached between her legs and slipped two fingers inside her and started finger fucking her, what did you do she told me she reached across and started rubbing his cock through his jeans, she then said i could feel it was at least twice size of your cock mark. then what i asked she said he just finger fucked her and she rubbed his cock, straight away i was thinking no way did Alan not take the opportunity and fuck her and no way did he just finger her for 45 mins, i left it though asking well do you want him to, she said feel how wet i am does that tell you what i want then she pushed my head between her legs and said taste my pussy see if you think i want his cock, as i started eating her out firstly i noticed the amount of cum inside her then came the taste i instinctively knew it was his spunk she was making me eat, i said nothing just drank it all down all the time she was asking if i liked the taste of her pussy when shes wanting his cock, i knew he'd fucked her earlier but played along and said if this is how he makes you taste you can dream of his cock all the time, i asked if Alan thought he had a secret and it was clear he did i told her she needing to tell him i knew while i didn't mind him fucking her it was a different matter if he was laughing at me, she told him during week and he asked what id said she told him he could fuck her but i wanted to watch he said that fine. nothing was said really the following week so wasn't aware what was to come, we went out as usual and .Alan ended back at ours, as soon as we got back Betty whispered to me to give her 10 mins then to send Alan up, like i said we hadn't discussed if we were going to proceed any further, anyway i did as i was told and after ten mins said to Alan, Betty wants you up stairs, he looked at me and said are you sure, seemed he knew what he was going up for, i said yes and he didn't wait for me to change my mind, i left them 10 mins so it wasn't uncomfortable for them after all she was doing for me wasn't she? when i walked in our bedroom Alan was on his knees on our bed with Betty on all fours with his cock in her mouth i walked over to side of bed and undid my jeans and pulled out my cock and started stroking myself while watching ,my gf of 6 yrs sucking my best friends cock, she was right his cock was easily 10 inchs and think too, after about 15 mins of her sucking him off she flipped on her back and said to him your turn and proceeded to pull his face to her dripping wet pussy, he immediately started eating her out, he lapped up her juices, she started to cum all over his face, she pulled him up and said Alan i need your cock now, i was disappointed that he pulled the quit up behind him and then started to push his thick cock in my gf pussy i could tell by the look on her face she was loving it, he started to build up a bit of a rhythm. Betty said afterwards she wanted him to fuck arse of her but he seemed to be holding back, maybe so i didn't get to see my gf fucked senseless in front of me, he did fuck her for about 25 mins then tensed up and shot his cum deep inside her just as he was pumping the last drops into her he looked across at me and said to her i can see why you need my cock pointing at mine and saying marios is tiny, she responded by saying wow Alan that was so good , i think im gunna need you to fuck me every week, he just looked at me as if to say well? i just said if that what she wants you better give it to her, he did look out for next chapter.
