The first time my wife brings a man home

Around 2004 my wife was going out  every week to a sports pub with her friend Sylvia, I would pick them up when they called me or they would get a taxi home. Most of the time she would be home by 2 am, but she started to stay out later and go to house party's, sometimes not getting in until 6 am or even later.
Sylvia's husband was the jealous type, so to avoid suspicion she would tell him she was staying at our house, so I had to make the guest bedroom up.  My wife would tell me when she got home,what she had been up to, sometimes while Sylvia was in the room and they would compare note's of the guys they had been with in front of me. they would also be in various states of dress and I have seen Sylvia's boobs, and as she wears very short skirts her knickers as well.

I have asked my wife to bring guys home loads of times, so that I can watch, but she has refused. She has had men while I have been out of the house, and has always said she wouldn't want me to watch.
Anyway, one week they were going out as usual, Mandy had a bath, then I shaved her and gave her an ..., before using an anal probe and her beads to check she was clean and then she would let me rim her. I really enjoyed getting her ready for her nights out. She would then get dressed and wait for Sylvia to turn up, so that she could leave her car at our house and drop off her overnight bag.
Sometimes Sylvia would get changed at our house into something "sluttier", on this night she arrived in a t shirt and jeans and left our house in a halter neck top, very short skirt with holdups and a pair of black knickers. I found it very hard not to keep staring up her skirt and she would know that I was looking and smile. They would usually have a drink or two before going out.
At about midnight I received a text from Mandy to say couldn't go back to the house they usually went to, but they had met some guys, and would I be OK if she brought them back to ours. I replied "OK"  do you want me to pick you up. I thought I was going to get to watch them, but the next text I got, said "I want you to stay in your study, we will go straight to our bedroom and you haven't to try coming in". I wasn't sure what to say, but while I was thinking about it, I got another text saying "do you agree". I sent a text back saying "OK"
The next text was about 30 mins later, which said "can you leave a couple of bottles of beer and a glass of water in our room and the same in the guest room for Sylvia, better leave some condoms for her as well, getting a taxi will be back in 15.
I was shaking and my cock was rock hard, but I got the beers and water as she asked, but left condoms in both rooms, I then waited in my study. It wasn't long before I heard a car pull up and then then our door opening. Mandy and Sylvia were giggling and telling each other to be quiet and at first I thought they were "winding" me up, but I soon heard men's voices, they then went up to our rooms. I was trying to listen, but could only hear muffled voices, but it wasn't long before I could hear the beds banging and moans, it was as if Mandy and Sylvia were competing on who could be the loudest. It was so horny to listen to and I was wishing I had set up a video camera. Every so often it would go quiet and then they would start again, it was hard to tell who was making what noise, but I clearly heard Mandy say "OH my god" and then "Oh fuck" and then "fill me", I ejaculated at this point.
It then went really quiet and thought they had gone to ..., when I heard footsteps, followed by our front door closing. A few seconds later Sylvia popped her around the door of the study and asked if it was OK if she had a coffee, I said I would make her one, so went off to the kitchen. I returned with two coffee's, Sylvia said that the guy she was with had gone, as he told her that he had to work in the morning, she then said "probably has to get back to his wife now he's had his fun". She was sat on our settee and I noticed she had one of my shirts on, and she said "I hope you don't mind" I told her "not at all". She had the top buttons undone and as it was loose on her, I was getting a glimpse of her boobs. Her boobs were very droopy, but she had really big nipples and I was trying to work out if she had knickers on.
She told me that Mandy was very lucky having me and that her husband was a virtual alcoholic and hadn't had sex with her for years, but was still jealous and wanted to know where she was going and who she was with. He was OK with her being out with my wife as He told her that "Mandy is respectable" if only he knew.
We then heard the sound of the bed banging again, followed by moans, I was embarrassed at first, until Sylvia said "that guy is relentless, he fucked me a few weeks ago and never seemed to go soft". I was surprised how casual she was telling me this, she then said that he was a body builder, well over 6' and used both steroids and viagra, she said that it wasn't so much how big his cock was, but that it was "hard as a piece of wood" and that he never seemed to go soft.
The noises from our bedroom got louder and I could hear Mandy crying out, I wanted to go up and stop it, but Sylvia told me, that was why Mandy didn't want me to watch and that she could handle it and would be enjoying it. She then asked me if I enjoyed listening to her, but before I got chance to answer, she said "actually it is quite horny listening to them fuck, isn't it". I just agreed, she then asked me why I enjoyed licking my wife after other men had "had her", I wasn't really expecting her to ask that, so I said "I don't know why I do, it just turns me on,she was asking if I liked the taste. I was embarrassed and was avoiding eye contact with her, she didn't press me for an answer, but said "I wish my hubby would lick me, even better if he cleaned up my lovers spunk"
As I looked up at her, I got my answer if she was wearing knickers,or not, she was wearing large black lacy knickers and I suppose I just stared at them, she said "do you like them", I said "yes", she then lay back with her legs open and rubbed her crotch through her panties. I could hear Mandy moaning and screaming and could hear the guy, but couldn't make out what he was saying.

Sylvia had undone the shirt completely and was squeezing her nipples, she then asked if I wanted to lick her, I wasn't sure what to say, as I didn't want to be "unfaithful" to Mandy with her best friend, but then hearing Mandy being fucked, I thought "why not". I moved over to her, knelt in front of her and started to peel her knickers down, the view I was greeted with shocked me, she was so hairy I don't think she had ever shaved, her lips were wide open and her pubic hair was matted with cum, which surprised as Mandy had told me to leave condoms in her room.
 I looked at the crotch of her knickers and it was soaked, I moved forward and started to lick her. The smell was so strong and she was so wet, I was licking all the way down to her anus to try and stop it running over the settee, before licking back up the length of her slit. Slyvia was whimpering and holding my head  as I licked and sucked, I couldn't believe how big her cunt was for a woman so small, I felt as though my whole face was being devoured by her pussy. As I was trying to get my tongue, deep inside her, my nose was rubbing against her clit, and she had an orgasm soaking my face with her juices.
She said "that was so good, now I know why Mandy likes it so much" I was still licking her and sucking on her pubic hair, she told me that I really liked to" lick it clean".
I moved up her body and first of all cupped her breasts, before taking one of her nipples in my mouth, my hard cock (still in my jeans) was rubbing against her pubic bone and she seemed to be enjoying it, when she said "sorry, but you can't fuck me, Mandy told me that you can only lick me" I was shocked that Mandy was in on it, she told me that Mandy had told her loads of times about me "eating creampie" and Sylvia had told her that she would love to try it, tonight Mandy told her "now is your chance, but don't let him fuck you" Sylvia then said "you can lick me again, if you want".
I didn't need to be asked twice, I moved down and started to lick her clit, it was much larger than Mandy's, and protruded, from her lips like a small penis, it was even prominent with all her pubic hair. I started to suck her clit into my mouth, which she seemed to enjoy. Mandy was getting really loud again, and all we could hear was "no - no - no" followed by "fuck me... fuck me". It was obviously turning Sylvia on as well as she told me to finger her, I finger fucked her while sucking and licking her clit, and she was telling me to use more fingers and do it harder, before long I had four fingers up her, she then told me to fist her. My whole hand went into her with relative ease, but she just kept saying, "harder". A white foam appeared around her opening as I thrust in and out ( I thought it was a good job I didn't fuck her, she wouldn't have felt my cock). It felt as if I was giving her a blow job as I sucked on her clit, and I thought I was going to hurt her as I rammed my hand into her, but every time I slowed down she would say "don't stop harder" Thankfully it wasn't long before she started to cum (as my arm was aching) she was shuddering and convulsing as she came, and held my head to stop me licking her clit and used her other hand to stop me fisting her, I held my hand fully in her as her pussy "pulsed" and I could feel her vagina start to grip my hand. I had to remove my hand slowly, so that I didn't hurt her and when I had done she lay back, fully on display her cunt wide open, she then said "you are so fucking good" I felt quite proud of myself.
It was then that I realised it had gone quiet upstairs and was worried Mandy might of heard us, Sylvia said "don't worry, she will be knackered if Jim (that's the first time I had heard is name) had just fucked her in the arse", she then went on to tell me how he had tried to do her anally, but she doesn't like it.
She said that she had told Mandy what he was like, but she knows that Mandy likes anal, all this talk about Mandy was making my cock hard (as well as Sylvia was still sitting back opposite me, with her legs wide open and her tits on display).We could hear them at it again upstairs, but not as loud I didn't realise I was rubbing my cock through my jeans until Sylvia "you can take it out if you want and wank". It was then I remembered that I had cum in my pants earlier
