It was at a party where Sadie first cheated on me.  It was at one of my girlfriend’s mate’s house’s that I had not been to before. I knew some of the girls had planned some games, but I had no idea what they were planning to do.    During the evening I noticed that four or five of the girls had disappeared and one by one men were being taken through to another room.  The men looked happy on their return and then another man was grabbed and disappeared.  Of course, although I knew that Sadie was a part of whatever was happening I had no idea what they were up to. 

It was at the bar where I heard two of the men that had already been through what the girls were up to, that I heard one telling how he got a blow job.  The other man was less happy to hear that as he only got a quick hand job and kisses.  Neither man knew which of the girls had treated them to their pleasant surprise.  After getting another beer I made my way close to the room and realised that there was a vent between the two rooms, the room I was in and the one the men were led into.   I moved slowly closer to the vent not wishing others to realise what I was up to.

Now just a foot or so from the vent I could hear a bit of girly giggling and some man giving several loud moans.  I had a grin on my face as I thought about what the lucky bastard was being treated to.  There was a final groan and then just a few minutes later he was brought out and a blind fold removed from his face.  I surmised that the lucky sod had been either treated to a hand job or if he was very lucky a blow job.  I just hoped that when it was my turn that I got the blow job.  I hadn’t even considered that Sadie was a part of what was happening.

Then I watched as Richard was led to the room a blindfold was placed on his face and then he was taking inside.  I knew my Sadie had long fancied Richard, and had I not met and started dating her I was pretty sure that the two of them might have hooked up.  I strained to hear what was happening and at first there was just some giggling.  I recognised Catrina’s giggle as well as Sadie’s but there was definitely a third girl with them and I couldn’t work out who it was.

Then I could hear what I presumed was kissing, although I did wonder if it wasn’t the sound made giving a blow job.  It went on for a few minutes and then there was a lot of rustling.  Then I heard something that rocked my world.  It was Sadie who squealed and then groaned.  I recognised exactly what was happening as Sadie often did just that with me.  It was when I would bend her over and penetrate her from behind.  She would always squeal as my cock first penetrated her and then groaned as it sink slowly in up to my balls.

Surely she hadn’t just let Richard penetrate her pussy.  Then I was left with no doubt as Richard started to grunt as he started to fuck my girlfriend.   I rushed to the door and barged my way in.  The room was in total darkness only broken from the light coming through the door.  As the door closed behind me I hadn’t seen a thing as my eyes tried to adapt to the lack of light.  In the mean time both Sadie and Richard continued to grunt and groan.  I was feeling around the walls trying to find the light switch.  All the time all I could hear was their grunting and groaning.

Finally, I found the switch.  For a second I stood there wondering if I should turn the light on or was it better not to see what was happening.  My pain and curiosity got the better of me as I threw the switch.  My suspicions and fears were answered in the first flash of light.  As I had suspected Sadie was bent forward holding onto the table in front of her and Richard was behind her, and yes, his cock was deep in Sadie’s pussy.  Either side of Sadie was two more girls.  One was Brenda and the other one was unknown to me. 

Sadie and Richard were both blindfolded.  The other two girls were steering and aiding them to fuck.  The other woman was also fondling Sadie’s boobs as she took Richards cock.  Brenda and the other girl both looked shocked that they had been caught out.  Although all three girls were still dressed with bits on show, mainly tits. I could see that Brenda and Sadie were not wearing any panties.  I had a clear view of Richard’s cock in my girlfriend’s pussy that was taking quite a hammering.  Richard also had a hand up Brenda’s skirt and was fingering her naked pussy. 

Both Brenda and the other woman looked shocked as I made my way towards Sadie who from the sound of her was pretty close to coming.  It was at that moment that the door opened again and I saw Catrina enter the room with yet another man already blindfolded.  She stood rooted to the spot as she had a shocked look on her face.  Then I pulled the blindfold off of Sadie’s face.

It took her a second or so to focus and then realised that it was me stood next to her as Richard just kept on fucking her.  Sadie squealed and stood up causing Richards cock to be expelled from her pussy and she ran from the room.   Richard took his blindfold off and saw all the people present still in the room.  He was quickly trying to stuff his still hard cock back into his trousers. He also quickly shuffled away.   At that point the other man also took his blindfold off and realising that something had gone wrong fled out of the room.

The only one that didn’t leave was Brenda.  She told me that it wasn’t meant to happen that way.  I was meant to be treated to a blow job before Richard was taken into the room, but Catrina dropped off and got the two of us muddled up and took Richard first.  Brenda told me that at first things weren’t meant to go as far as fucking, but she had ended up getting fucked as Sadie steered some bloke to her pussy.  She was only meant to give a blow job, but Sadie found Brenda  bending her over and before she knew what was happening some chap was fucking her.  She said she decided that she would return the favour to Sadie when Richard was brought in, especially as she knew that Sadie had fancied him.

Although I was hearing that it was a game gone wrong I was still livid and went to try and find Sadie.  I was annoyed as she could so easily have stopped it from happening, but instead she just stood there enjoying it.  I couldn’t find Sadie anywhere and was eventually told that she had left the party and probably gone home.  I went to my home still in a temper.

It was a couple of hours later when Sadie rang me and asked if we could talk.  I told her to leave it till tomorrow and to come to my house.  Sadie kept telling me she was sorry and it was a mistake and a game gone wrong.  I told her to come to my house the following evening and put the phone down on her.  I was still livid and started to plot my revenge.

From my bunch of mates, I knew that Sadie hated Matt although he had the hots for her.  I rang Matt and asked was he free the following evening and he told me he was and I instructed him to come to my house the following evening if he wanted some fun.  He wanted to know more but I told him he would find out the following evening.  As my plan came together in my head I went to the garage and got some ropes and fashioned some restraints.  I worked out just how long the ropes needed to be for the slip nots to go on Sadie’s wrists and still be tied at the other end to the bed legs.  I also made up two more to go on Sadie’s legs.  Next I found an old scarf that was just right for a blind fold.

Matt was round quite early and I told him all about Sadie cheating on me and what had happened.  I think his words was, “What a bummer, what are you going to do about it?”  I told him that it wasn’t me that would be doing something about it and told him my plan.  Then the door bell rang and I quickly went to the front door and found Sadie and Brenda there.  I told Brenda that I really didn’t want to see or hear from her, but both Brenda and Sadie insisted that she stay.  Reluctantly I let Brenda come in with Sadie.

As soon as the door was shut I told Sadie that as she liked games so much I had one set up for her, and she was stunned as I blindfolded her and led her up the stairs and into my bedroom.  Brenda looked stunned to see Matt was there and I indicated to Brenda to keep quiet.  I was glad that she did, as I sat Sadie on the bed and rolled her over onto her back and before Sadie had time to think, yet alone respond, her hands were in restraints and I was putting her feet into the other restraints.

Sadie was complaining that she didn’t like what was happening.  I told her she liked games last night.  Both Matt and Brenda just stood watching as I took my cock out of my jeans and stuffed it into Sadie’s mouth and proceeded to fuck her mouth.  I indicated to matt to undress which he quickly did.  Then I withdrew my cock.  All this time Sadie was struggling but she was unable to get her hands free and the more she struggled the tighter the knots on her wrists got.

I moved around and lifted Sadie’s skirt and as I did so Sadie was asking Brenda to help her.  The look I gave Brenda told her not to interfere and she told Sadie she wasn’t able to help.  I suddenly realised that I couldn’t remove Sadie’s panties without undoing her feet and reached for a knife I keep in my bedside cabinet and unceremoniously cut the panties off of Sadie’s legs.  I fingered her pussy for a few moments and Sadie relaxed a little.  As soon as she stopped struggling I indicated for Matt to replace me.

I was a little surprised that Matt was straight between Sadie’s legs and licking and sucking at her pussy.  It was clear from Sadie’s moans that she was getting worked up by Matt’s tongue.  It was when she called out for me to get on and fuck her that Matt looked at me as if to ask did I really want this.  I nodded for him to go ahead and fuck her.

Matt was on her and in her like a rat up a drain pipe.  Sadie squealed and groaned.  How many times had I heard that squeal and groan?  Matt started to fuck Sadie.  As he did, I moved to Brenda and stood behind her and put my hand up her skirt.  Brenda just stood motionless as my fingers found her panties and slipped beneath them and into her pussy.  For me this was a bonus.  Revenge on Sadie and have some fun with Brenda at the same time.  Brenda opened her legs wider to allow me easier access to her pussy as she stood motionless watching her friend getting a good shagging from someone other than who she thought was fucking her. 

I was more than happy when Brenda’s hand came back behind herself to the front of my jeans.  I used my other hand to release my zip and help Brenda free my cock.  Brenda was quickly wanking my cock for me as she watched the show on the bed.   Matt was giving Sadie a real good fucking as I eased Brenda’s panties to one side and steered my cock towards her pussy.  For a split second Brenda stopped my cock from going between her legs and then she suddenly let go and allowed me to slide between her legs. 

It was now Brenda’s turn to groan as my cock penetrated her pussy.  Matt turned to see what was happening behind him.  The groan must have alerted Sadie that things weren’t how she thought they were.  She called out and asked who was there.  The game was up and I decided it was time.  I told Sadie that as she wanted to be a slut I was helping her to that end and indicated to Matt to remove her blond fold.  Sadie was already moving her head from side to side trying to throw the blind fold off.  Matt quickly held her head still as he undid it and removed it. 

As she saw Matt on top of her she squealed telling him to get off her.  I told Matt to finish fucking the slut.  Sadie could see that I was fucking her mate and told me to get off of Brenda.  Brenda didn’t say a word, but she did groan as I slammed in and out of her pussy.  Matt had also resumed fucking Sadie who was now gasping as he ploughed her pussy.  I was telling Matt to fill that sloppy slut’s cunt with his cum.  Sadie was gasping no, but I could see that she was close to coming.   Matt just kept on banging away at her pussy.

Then she was telling Matt not to stop as she started to go into her orgasm.  Matt had no intentions of stopping and neither did I as Brenda started to shake.    After Sadie came groaning and moaning Matt emptied his balls in Sadie’s pussy.  Brenda and I quickly followed them to our mutual orgasms.

It was a short while before Sadie recovered enough to insist that she was untied.  I told her I would undo her when we had finished with her and not before, and that sluts should just take what was offered.  Sadie started complaining, so I found her destroyed panties and stuffed them into her mouth as I told her she had more to come yet.  Brenda was now sat on the side of the bed still recovering. 

If looks could kill, I would have been dead, as I slipped my limp sticky cock into Brenda’s mouth.  I suggested that Matt did the same with Sadie.  Through her panties she managed to shout that she would bite it off if he tried.  To rub things in I told Sadie that she might be a slut but her friend was far better at giving blow jobs so she obviously needed more practice.  She again indicated that she would bite Matt if his cock got near her mouth.

My cock was beginning to recover as Brenda did a very good job of sucking it.  As soon as I was hard enough I moved onto the bed and between Sadie’s legs.  She was trying to complain but I told her that tarts just did what their man wanted as I slid my cock into the sticky mess already in Sadie’s pussy and began to fuck her.  I heard movement behind me to see that Matt now had his cock in Brenda’s mouth as he watched me fucking Sadie. 

It wasn’t long before Sadie was moving her hips.  The dirty slut was enjoying what was being done to her.  I fucked her for a while and I had to remove her panties so she could breathe easier.  It was clear from her moaning that she was enjoying herself.  I had noticed that Matt was hard again and offered him Sadie’s pussy again if he wanted it.  He said he did and there was no complaints from Sadie as we swapped places and he slipped his cock back into Sadie’s pussy.

I had Brenda suck my sticky cock that had a mixture of all four of our juices on it before taking her doggy style on the floor.  Both Sadie and Brenda both took second loads in their pussies.  After some recovery time I finally untied Sadie but held her still and pushed my sticky soft cock into her mouth and told her to suck.  She did but it was far to early to get a third erection.  As I moved away from her Matt took a turn in Sadie’s mouth and although all her threats to bite him she didn’t and just lay there sucking his cock.

It was some time later when I drove both Brenda and Sadie home.  I told both of them that they were to return for further slut training.  I was surprised to hear both of them say yes.  I told them to be at my house for eight o’clock and to have Catrina with them and none of them was to be wearing any panties.
