first off i have to put a little background into this whole ordeal

so about a week ago, my then fiance (a) approached me with what seemed like the best thing ever. i was asked if i wanted to have a ffm ménage à trois. me being a guy, i delightfully obliged. we started looking on multiple sites. we found a site with a decent population, nothing like facebook though. my fiance had made her account, posted requests on a public wallboard, a couple of days go by. she is messaged by a guy (j1). this lad was telling her about this women only two years older than me (im 24, fiance=21). j1 got a in touch with a women we will call "v". v talked a into coming over for a bit for some fun, then come back to a and is' place. a comes back with v, i meet v, who has some pretty big sweater puppets but her face is not all that, but hey, doesn't matter, had secks. all three of us go upstairs and roast a bowl and immediately get down with our bad selves. a receives from v the worst lunch session, ever. bare in mind, this is the first time a has ever had this kind of experience and lets just say v did not live up to the whole "women are better at it" thing. luckily that had happened way let in the fiasco. a was irritated and very adiment about finishing by now so i did (it was glorious). a leaves to drop v off back at her place.

sorry for the incoming wall

fast forward 6 days ago

this single largest fuck up of my entire life is imminent.

a was wanting to try the ménage à trois with another female. she said i could find one as well, using the same site. i was minding my own, looking through babes. i get a message from v, we chat for about an hour, she says night and signs off. i'm still on the site looking when i remembered i wanted to ask her a quick random question, so i message her while she is signed off. 30-40 minutes later she replies to my question. then tells me she cant sleep, and that she needs a phallus in her to sleep. i jokingly (at first) said i could help (stupid?) she throws an lol, then tells me she has tried using certain products to vibrate herself to sleep-dom, but tells me it only made it worse. i insisted i help with her problem, but this time in all seriousness. she very happily obliged. we exchange numbers, i get her address and i head over to her place to participate in some serious cheating. we did it in multiple positions. there was one position where her shallow lady bits must have not been able to handle me. i got too deep and made her bleed. an hour 1/2 goes by and we finish, we smoke a cigarette when she asked my if a knew i was here. obviously a was not okay with this as i was her so. me not wanting to ruin the rush, i said yes. this gave her butterflies apparently as the expression on her face was of pure joy, from what i could tell. we hug and i leave, i get home at 4 am. i take a shower. as im doing so a walks in and asks why im still up. i reply that i just cant sleep. there was no suspision of cheating from her as she said ily and whent back to bed.

that was fuck up numero uno

the next day, i hear nothing from v. this is expected as she works two jobs everyday and is not one to use her phone a lot on the job. come about 10:30, i get a text saying she is having a party in a sauna at her place. she of course asked me to join her. i was sitting at home with a, so i really just couldn't be like "hey gonna go to a sauna party with out you". i said not tonight, v replied with a sad face and "k". an hour later a wants to go to bed, but i want to smoke a cigarette before hand. knowing we didn't have anymore i went to the petrol station to grab more. i got back and realized i had locked my self out of my apt at 12 am. fml. i had texted v saying i locked my self out. she instantly replied that i should stop by for some fun. i was unable to reach a as she was asleep by now. i idiotically went to the party. i arrived, v let me in. i get to the sauna where two other people were drinking, one was j1 and the other one we will call j2. j2 is sloshed, he is stumbling around, so he went to bed about an hour after i arrived. 
now for some reason v must have felt uncomfortable around j2 as it was only after he went to bed did she just wip out her knockers. they were just there, to be looked and freely groped at me and j2's discretion. all three of us drink more and fondle the most dtf women i have ever met. j2 gets drunk and passes out inthe rec room. leaving v and i awake. v takes her the bottom of her swim piece off and just as with her hooters her flower was open to me and my desires. knowing i have a relation ship with a (and a very good/stable one). i was hesitant about doing anything major. it was only after 3 more tall boys to my lust prevail. the next thing i know, we were making out in the sauna, grinding moaning and just being sweaty human beings grinding on each other. she whipped out my member and we had secks in the sauna for about 45 minutes. we both finish smoke a couple of ciggs and be close.
i sober up and leave after about an hour after we finish.

i get home. 

the magnitude of what i had done the past two days hit me than while i sit in my car smoking a cig waiting for some one to open the door so i can get back in. the door opens after about two more cigs. i get inside. while i was in the car knowing what i had done was not good in anybodies book, i need to mitigate the amount of evidence that would get me fucked by this. i started to look for a's phone to block j1 so that he could not let a know what i had done. i accidentley wake a in the process (its about 5 am at this point) seeing that i was still dressed, she asked what i was doing. i told her i got locked out and drove around for awhile. she believed it. i all of a sudden felt this really deep sickness at the bottom of my stomach, the guilt was making itself known. i ran to the bathroom and puked. the weird part? it wasnt beer, all bile. i told a that i had lost my phone and needed to use hers to find it. that was my cover for needing her phone to block j1. i blocked j1 thinking mission success, never gonna do it again and she willnever find out.

boy was i wrong.

we wake up, a checks her phone and see a txt from a random number. a finds out it is j1. j1 asks why he was blocked. a says she didnt block him. a asks me if i blocked him. i said yes for a random reason.

j1 drops the bomb shell of my life.

a finds out that i had cheated on her not once but twice, she is furious, rightfully so. screams at me and leaves for work. my life the next two days has been nothing but high pitch banshee words with the searing heat of a thousands suns on my ear drum and i deserved every bit of it.
