So a little backstory,

I have been (now should say was) with my LTR for about a year. My LTR has always thought i'm sort of a man-whore, and treated me pretty great aside from the fact that her biggest insecurity was me fucking everything that moved. (she has known, even talked to former plates who have told her about me etc etc)

My LTR was submissive, cleaned my house regularly, and would do anything I wanted sexually without question. Even if we got into a fight over something sex would still happen regardless. She would usually suspect me of fucking around, blow up like a crazy person, I would ignore her and she would end up back in my bed days later. If it weren't for the sex being quite good and knowing how to deal with her immaturity I would have cut her off by now.

So about a month ago, she tells me she wants to give me a threesome. She know's I have wanted to have one (but I never pushed it, just would make fun comments on occasion) and usually she is always trying to what she can to please me. I ere on the side of caution, not getting overly enthusiastic and letting her do the legwork on this one. (at some points I thought it was just a trap)

About a week and a half ago she invites me out with one of her girlfriends who she thinks might be a good fit. We both go out, and after a few drinks I decided I was not interested in having a threesome with this girl. The 3rd person was an HB6 at best, way too skinny for me, and acted pretty white trash. (when we were out downtown she mentioned about 3 different bartenders that she had slept with over the past month).

So two nights ago, Im working (I am a bartender as well) and this girl who knows my LTR approaches me. HB8, great body etc. Im not particularly interested in this girl at all, but I have a dick and it works.

The HB8 is buzzing and tells me how badly she wants to have a threesome with my LTR and I. She talks about the things she would do to my LTR and trying to come up with ideas how to make it happen. I told her my LTR was at home, and HB8 insisted that I invite her over after work.

Now I know how insecure my LTR is, and I knew she would probably lose her damn mind if I just showed up at the house with some random girl. Regardless, I figured I might as well give it a shot since my LTR isn't going to last forever anyway.

HB8 insists that she is going to take care of everything and make 3some happen. I throw my hands up and hope for the best.

So we get home and my LTR opens the door (its about 2am). She is very surprised and sneaks a death glare at me. I shrug it off and smile "hey babe!" and begin doing my own thing to let HB8 hang out with LTR. As I'm outside walking my dog I get a text from LTR saying,

"Cant fucking believe you are showing up with this girl expecting this to happen. Of all the things that you have done this is by far the most insane and offensive"

She's upset as I expected. I texted her back saying "say the word and I'll just take the girl home, no big deal"

I get back upstairs and HB8 and LTR are in the living room laughing and drinking at this point. LTR comes in to use the bathroom and catches me to say "HB8 is trying to kiss me! I cannot fucking believe you!"

I act indifferent and remind her that if she wants to hit eject to do so whenever she feels like it.

I stay inside checking emails and doing some work while she goes out to the pool with HB8 to "get some air"

I stay inside for about 20 minutes checking emails and finishing some work. I go into the kitchen to make a snack. I then hear the front door open, then I hear my bedroom door open.

I walk into my bedroom, and there they are, in all its glory HB8 and LTR making out like two kids on prom night. I walked in, stood near the door, and just played it cool.

LTR looks over at me, and gives me that look like she wants my cock in her mouth. I go over, get on the bed, and she starts sucking me off while HB8 is going down on her.

For about 45 minutes, we are doing all the things. Only thing that I didn't do was have sex with HB8, as we were taking our time and was just letting things happen naturally.

My LTR is in heaven. She's in disbelief at whats happening, and her body is reacting to everything like crazy. I couldn't keep track of how many orgasms she had, but she even squirted at one point.

All of a sudden, LTR gets up and says "I have to use the bathroom, be right back". She gets up, and walks out of the room. HB8 and I are laying there, just chatting a bit, and after about 10 minutes we decide to go check on LTR.

LTR left and was outside waiting for a ride. Dressed and with all her stuff.

"you are disgusting. I wish I never met you. I hope everyone realizes what a piece of shit you are. I should have listened to everyone that warned me about you. I cannot believe you tricked me into this shit. Fuck you"

I was shocked, but at the same time It felt like something she would do. She told me we were done. I held frame, tried to explain for a few minutes, but I knew I wasn't getting anywhere. Nothing I do or say would change whatever the fuck is going on in her head at that moment. She told me to stay away from her, and leave her alone completely. I said "okay." Went to the gym that night and went hard.

Yesterday I got about 20 text messages and 3 missed calls, all with voicemails of her telling me how much she hates me, that Im a scumbag, she wants to get checked for STD's now and thinks I am a sick fuck. Also accusing me of fucking HB8 all night after she left. (never happened, did not deny, just did not reply)

Today I have received two emails from her saying to stay the fuck away from her and about two pages of her going off on how she thought we were special and I completely ruined it.

She's pissed, but she is also a woman. I can't say I feel great about the whole situation, but I know nothing I say matters or will change anything.

I haven't replied, but we do have mutual friends and I know she is going to try to make it ugly.

Any words are appreciated, I don't plan on doing anything other than going to the gym and focusing on me for the next few weeks.

TL;DR Got LTR to have threesome and got dumped afterwards.
