I have always enjoyed reading cheating girlfriend or wife stories and regularly used to buy Escort men’s magazines where there was always sexy cheating stories.

I would wank myself off to these cheating stories and always found them mega erotic.

Fast forward a couple of years to 1990 where I met my wife then girlfriend.

She was blonde 5ft 8inch talk long legs curvy body and big tits.

I found her very sexy and someone I knew said she was a right hot arse.

Not long after we met we just got on to a conversation about cheating girlfriends and I said I always found it sexy.

“What do you mean?” She said.

I just came out with it “well if you ever get an opportunity I’d give you permission to fuck another man”.

My girlfriend looked a little shocked and said “You serious you want me to have sex with another man?”

“I’m just saying I find it sexy and if you ever get an opportunity I’m ok with that”.

“Well I guess I’ll be ok with that as long as you are” she said.

“As long as I get to hear about it, or better to watch it”.

“You naughty boy” she said.

This conversation was in my car and my cock was rock hard that she was ok with this and the thought of my girlfriend allowing another man to fuck her really turned me on.

She felt my cock “Whoo someone’s hard, you really want me to get fucked don’t you”.

“Yes” I said

She then sucked me off and I shot my load into her mouth which she swallowed, then gave me a big kiss. She had a glazed look and she was also turned on.

“I know just the person” she said.

“Who” I said.

“David, my ex” she said.

“He’d fuck me in a heartbeat and he’d love to do it in front of you he’s a strong personality”. She said.

My cock became hard again as I knew the situation with him.

Her ex was a bit of a bad boy, brushes with the law a rough diamond, she ended the relationship just under 2 years ago as she had enough but also as a young woman wanted to play the field. He had also been a bit rough with her and used his hands once or twice but she said he was a very good fuck and had a nickname with their friends Horse as he had a big cock. She said he also knew how to use it.

She told me everything about them and that one of his favourite things to do with her was to fuck her in the arse. I could tell my girlfriend had taken it in her bum as one of my favourite things to do to her was to lick her bum and she had a twisted bit of skin like a dink in her anus.

He had on occasions had Stella join him and his friend for a threesome and sometimes would end up having a two’s up (double penetration). Also at this point we hadn’t had anal sex she said it was for special occasions.

So a couple of months later as I mentioned 1990 my girlfriend was 20 years old me 22.

Her ex was 5 years older.

It was summer and we both lived with our parents and her parents were on holiday.

“Meet me at my parents tomorrow after work you can stay”. She said.

I knocked on the door and she answered and my eyes nearly popped out.

She looked super sexy had green underwear  on skimpy French knickers and matching suspenders with black fishnet stockings, I vividly remember even then she had bright red painted toenails.

She led me to her bedroom but I had an odd feeling. We began to passionately kiss,her nipples were hard and her neck was really red, she always had this after being turned on or after having great sex.

I quickly removed her knickers and began to finger her pussy which was very very wet.

There was also a musky distinct smell in the air.

I went to go down on her but she told me not yet but sank to her stockinged knees and began to give me a blow job (her specialty).

It wasn’t long she was more in control than we ever were and pushed me in the bed.

Now normally we would start to have sex in the missionary position then maybe a couple of different ones.

“I’m going to fuck you” she said and got in top of me and straddled me.

She began to ride me and swayed her hips and really controlled her vagina muscles on my cock, she hadn’t fucked me like this before but it was so good.

After a couple of minutes of her fucking me I could hear something, I startled slightly but she put a finger to my mouth.

“It’s ok” she said.

I turned my head to the left and saw a bloke stark naked, he had a big cock and it was very erect. If I’m honest it wasn’t a nice cock to look at he was circumcised but it was thick and veiny. He was at least an inch bigger than my 6.5 inch.

I obviously had an idea who this was, and the sheer size of this bulls cock I remember having a pang of angst and thoughts of what I had wished for.

She looked at me still gently riding me “This is David my ex” she said.

He had a smug grin on his face and said nothing but brought his cock to Stella’s face right above me.

She sucked him off while riding me and this was my 1st ever experience of a threesome, you could tell these fuckers had done it before.

I continued to fuck my girlfriend while she sucked her ex boyfriend’s cock and I had a birds eye view. Every know and then a mixture of saliva and possibly his pre-cum dripped onto my neck.

A couple of minutes passed he removed his cock from his ex girlfriend’s mouth my now girlfriend and moved behind.

I really had a pang of dread but was also excited and couldn’t believe how much of a slut my girlfriend was, but she was only fulfilling my fantasy or was she?

I could see him lubing his cock and rubbing a lotion all around his thick veiny shaft and noticed him put a huge blob on his bell end.

Then a blob on his two fingers, next with my cock firmly in my girlfriend’s pussy I could feel those fingers in her bum and prodding around getting her ready for a two’s up.

I looked at her face her eyes glazed she was looking at me she looked really into this had an almost crazed look of lust on her face.

Next thing I could feel David get into position on the bed and then felt his cock next to mine slide into her arse through the thin walls between her bum and vagina.

As he entered her and gave her another DP my girlfriend’s eyes rolled and she gave out a loud moan.

This was it, this was what I wanted and the angst began to disappear as we both fucked her.

I must admit that it was one of the most erotic feeling I have ever experienced not sounding gay but our cocks rubbing together between her holes really turned me on.

I wasn’t going to last and I said out loud “I’m cumming” I shot a load of sperm in her pussy.

After I had done my business Dave totally took over as my cock slipped out and a glob of cum leaked onto my belly and pubic hair.

“Stella said you want to watch her get fucked” he said.

“Yes” I said.

“We’ll sit over there and watch me fuck her”.

I did as I was told and they had got into a spooning position where I had full view of his fat cock sliding in and out of her arsehole.

I may as well not been there as the two lovers fucked in lots of different positions, the fucking slut even did ass to mouth.

They must been at it half hour then David summoned me over and told me “I’m going to cum in her cunt, hold her legs while I fuck her” he said. I did as I was told as he began his final assault on her red pussy, her lips protruding from the intense session.

As I held her legs I noticed him starting to fuck her really hard and she was moaning and I knew that very soon he would shoot his nut into her where he had done many times before but this time with her new boyfriend present.

After minute or so he grunted and slammed into her and slammed again as her spunked  up her, also as he came he began to bite her neck and gave her a huge lovebite.

Shortly after he pulled his thick cock from her and I could see he was a heavy cummer.

Their juices glistening his cock.

It wasn’t over there as they had planned something very nasty and naughty between them for me.

Stella didn’t say anything but pointed at her pussy to me, I needed no further instruction as I moved my face towards her sex, the smell was unbelievable really musky.

As I began to lick her exes sperm from her pussy I could hear a click and a whirring sound.

David was taking Polaroid’s of me cleaning her up and said that he was keeping them and going to tell and show his friends what had happened, Stella laughed fucking slut didn’t care. Angst definitely came back but this was my doing and I had to take it on the chin like a man.

A couple of months later we were in a local pub Stella and I, and guess who was in there with a couple of mates. Yes David, and they were looking over and giggling Stella gave a wave.

To be fair I honestly didn’t care no one was hurt just something incredibly erotic and sexy that happened and was my kink.

David even came over to talk to us and had a couple of drinks.

We ended up going to his flat that night with one of the guys that was with him for old times sake, but this time there was no participation for me just to watch a DP.
