I had been dating K for a little while and she had been very clear with me from the get go that it was non exclusive. 

When she first told me she was dating other guys I figured that why its dating not coupling or marrige, its for exploring.

I had mostly been in monogomous relations and they were quick to bind once we had sex, K was different.

No matter how much sex we had or how many orgasms I gave her she just wanted to go on dates with other guys

At first I just ignored it but she began to talk about them, the way they fucked her or size of their cock or how hard she came.

I became a bit insecure and to hide it I pretened I was beyond it. She took that as a full ok and dove in deeper.

She loved to go to the bar and would go out drinking at night and meet men and go behind the club and make out or give head.

I had a few friends come and tell me that my girl (she now lived with me) was doing other guys.  I told them I knew and it was ok

That led to a few of my frineds fucking my girl and that led her down a road of total drunken whoredom.

She began to sport fuck looking to cuckold me and using me as her confidant and supoorter but sex became less frequent

I had bought her some fun lingerie and she began to ask for more and constantly wear it out to fuck other guys but not me

We would spend time togeher before her dates and I would help shave her or choose outfits with her that she would model.

I was often involved in taking photos of her that she would sent to guys she was fucking or wanted to fuck

Sometimes it would get her horny enough that she would have me lick her cunt til she came but I got nothing.

I began to feel like I was not worthy of having sex with her and I was  turned on by her stories of other guys

Masturbation while licking her pussy became my main form of sex and when she went out I would sissy out and toy my hole.

When her car was in the shop she wanted me to drop her off and pick her up from her dates and I obliged.

It was sometimes intense for me picking her up, she always smelled of booze and other men and sex even tho she showered.

One night she called me early to come get her and she seemed a bit frantic. I guess the guy was rough and rude.

When I picked her up she seemed all out of sorts and her outfit and make up were a mess, we drove home silently

Once inside our apartemnt she pulled me into the bed and pushed my head down to her crotch.

She smelled strongly of sex and certainly was unshowered but I did my duty and began to lick her

She was grinding on my face and saying things about the huge cock that was just in her when she started to cum

The orgasm dialated her and a big load of the rude guys cum oozed out of her.

I had been eating my own cum for years and was always curios about other mens cum. I touched my tounge to it softly

It was everying I wanted.  I became ravounous, like a switch went off and I gobbled it up and she passed out. 

I stayed up late fantazing about drining cum and wondered about my sexual identity.  

The next time she went on a date I was highly suggestive that she let the guy cum in her again and not to shower.

She thoguht it a bit strange as a request but was willing to comply and for her was more convineit anyhow.

This became our primary sexual engagemnt, me getting her ready for her dates and her returning with a strangers cumload

I really got into it and she started to tease me about being a cum loving cuckold and that I might need to start dating guys

That really sent me deeper down the sissyhole and I began to wear my panties daily and slighly hoped she would catch me.

We had intercouse so rarely at that point and she was busy sport fucking and no longer cared about me or my cock at all.

She started to tell her freinds that I was a cuck and she was using me and one of them told me what she was saying.

I felt totaly dismissed by her and it was extra hard that she made a point to fuck any guy friend I had and tell them i ate cum.

My isoaltion and constant sissy masturbation started to separate us more and we started to fight more and eventually ended.

I kept some of her cum soaked panties and woud suck on them while masturbating after we broke up.  I moved away after that.
