In my late teens myself and my older brother would swap girlfriends or partners.  We had done this quite a few times and I had watched Brian shag my girlfriend while I did the same with his.  By mid-twenties I found a girlfriend that I didn’t want to swap, and we stopped the swapping, and I went on to marry the girl.   Almost straight away my new wife suspected me of cheating as she knew about Brian and I swapping partners in our teens.  She was wrong as I had been totally faithful to her.  It still tore us apart and eventually she ran off with another man.

Pretty much at the same time as I was getting divorced, Brian married Kerry.  Kerry was gorgeous and just a little younger than my brother making her the same age as me.  From day one I fancied the pants off Kerry but being married I thought she was out of bounds.  It was at my twenty ninth birthday party in our local pub where I got very drunk and confessed to Brian that I fancied my luck with Kerry.  He was also pretty wasted and just laughed at me.  It was just a few weeks later that I went out with Brian, Kerry and Sandy.  Sandy was an on and off girlfriend.  As usual it was quite a boozy night and when we all got back to Brian’s house Sandy fell asleep on the couch.  Brian and Kerry went off up to bed and I was left watching a late-night film.

It wasn’t long before I could hear Brian making out with Kerry.  She was a noisy lover and was soon moaning and groaning for all she was worth.  I ended up wanking off to what I was listening to before deciding to walk home, leaving Sandy where she was.  A few days later I was out with Brian and told him how jealous I was hearing him fucking Kerry.  Brian told me that he thought that I was lucky to have Sandy to fuck.  I told him that I hadn’t that night and had gone home, but yes, she was a good fuck.  Brian joked that we ought to swap.  I laughed it off thinking he was just teasing me.

It was a few weeks later that we were out again as a foursome.  Sandy was pretty wasted again when we finally got back to Brian’s.  Again, he and Kerry went off to bed leaving me again watching an old film.  This time there was no noises from their bedroom as I listened over the film.  Instead, about fifteen minutes later Brian came back into the room still dressed and told me to go into the bedroom.

Imagine my shock to find Kerry splayed out on the bed.  She was naked and her hands were tied to the bed headboard.  Written on her stomach was fuck here with a big arrow going down to her pussy.  In seconds I had my hard cock out and offered it up to Kerry’s mouth.  She willingly sucked it in right up to my balls and then for several minutes I face fucked her.  I was in fear of blowing my load, so I pulled clear of her mouth and pushing her feet towards her hands I moved in on her pussy and played my tongue across her clitoris that was peeking out form her pussy lips.  Kerry groaned loudly.  She was already getting wet down there and I was lapping all her juices up as they flowed.  Kerry was wriggling her hips as my tongue teased her pussy and clitoris.  She moaned and groaned loudly.  Then she got even louder as she started shaking and then she was into a full-blown orgasm, and I could see her eyes rolling in her head.

As she started to calm down as the orgasm passed, I placed myself between her legs and slid slowly into her wet pussy.  Kerry’s moans started to build again as did the feelings in me that told me that I was soon to come in my brother’s wife.  Kerry started to urge me on with her hip thrusts and telling me not to stop, not that could or wanted to anyway.  Then it happened.  Kerry was thrashing her head around as she plunged into another orgasm, and I gave her three final stabs with my cock and then buried it deep as I came long and hard in her pussy.

I rolled off Kerry and lay next to her as I recovered.  Then I asked Kerry about her restraints.  She told me that Brian liked to tie her up when he would give her to other men, and she said it felt so naughty but also good being forced into making love with others and it wasn’t her fault as Brian had done it.  As we lay there, we suddenly heard Sandy moaning.  It was clear that Brian was having his way with Sandy.  I untied Kerry and went and watched my brother fucking Sandy.  As we watched I got hard again, and as I stood behind Kerry, I steered my hard cock back into her pussy.  Kerry’s moan caused Brian to look our way and grin as he saw me fucking his wife.  It was very shortly after seeing us that Sandy was coming, and Brian was groaning that he was going to come.  As nobody told him not to, he came in Sandy’s pussy.  That started Kerry coming, and I followed through and gave her a second load deep in her pussy.

Shortly afterwards both Sandy and I redressed, and I walked her back to my place where I had sloppy seconds with her.  I’m not sure why but the next day she refused to have anything to do with me and that was the last time that I went out with her.  I guess that swapping wasn’t for her, or allowing my brother to use her. 

After that night I talked with Kerry, and she told me that Brian would often allow other men to use her and sometimes he would avail himself of the man’s partner.  Other times he would just watch her getting fucked, often by total strangers.  Over the next year or so Brian allowed me to use Kerry.  I also made love to her without Brian knowing about it.  Kerry seemed to especially enjoy that.  It was a good time, and then I met my soon to be wife.  I told her about Brian and Kerry, and it didn’t scare her off.  Far from it she wanted to meet them and on just our second evening out with them we swapped partners.

Judy seemed to love it and soon we were swapping regularly.  Judy became good friends with Kerry, and they would often go out together.  Then one night in bed Judy asked me if I ever fancied doing what Brian does with Kerry.  When I asked her what that was.  Judy told me how Brian would tie Kerry up and then allow other men to use her.  I told her it hadn’t particularly been one of my things and asked did she fancy that.  I was stunned when she said she loved the idea of it but was a bit scared at the same time.

A few weeks later and just the day before her birthday I told her that I had a treat for her.  That was when I tied Judy up to the bed and blindfolded her.  She thought that I was just mucking about until she heard another man’s voice as I let a mate in to use Judy’s gorgeous body.  I must admit having the power over Judy as I allowed and watched a mate suck and fuck her was a real turn on, and I could now see what Brian gets from it.  On that occasion Judy didn’t get to see who fucked her.  Afterwards she said she felt safe although excited and scared at the same time as she was used by a stranger.

Since that night Judy has slept with a dozen or so men, none of which she knew.  We also swapped with Brian and Kerry quite a few times.  As I said Judy is soon to marry me, and she wants to start a family, so all swapping has now stopped but I am pretty sure that once we are married with kids she will want to be used and swapped again.
