UPDATE: Random threesome with my wife and her friend Liz has got me in trouble

Here is the first post: https://www.reddit.com/r/gonewildstories/comments/3fbfay/my_first_threesome_mff_has_me_worried_and_it/

So I have gotten a few PMs so thought I would respond with an update. Crazy shit has happened and I fucked up bad. I have never felt like this before…so much shame and regret and guilt but I have a small feeling like I've done nothing wrong…but I know I have.

So the threesome was definitely at the urging of Liz and my wife gave in and wanted to try it. Two days after the threesome, I noticed by her backhanded comments that she was regretting the whole thing. So even knowing all that, Liz manages to get me over to her house Friday afternoon (day before my birthday) and seduce me. This time, no wife though. We were alone and we fuck for over two hours. I came twice. It was maybe the best sex I have ever had but I cheated on my wife. Liz is acting like it's not cheating because my wife approved of me having sex with her. But Liz knows that's bullshit which is why she is saying we don't tell my wife we fucked without her. Liz is saying that we will fuck again with my wife and everything will be fine, but I know my wife probably won't do another threesome again.

My first threesome (MFF) has me worried and it already happened…

So, my wife presents a threesome to me last night out of nowhere…it was amazing, but so random, and I can't help but think there is a hidden reason for this. Is she cheating? Or maybe she just wanted to do something special for me? My wife seemed really shy and weirded out at first…so I'm not sure she did it to satisfy a fantasy. Maybe Liz pressured her into it? Liz was definitely really into it.

Some backstory:

My wife has been friends with Liz since college. I'm sure they tell each other everything. I do know that Liz is aware that I have a pretty big cock. She drunkenly told me at a party one night that my wife told her. My wife and I have also talked about how curvy and voluptuous Liz is on a few occasions through normal discussion. One night during drinking I made an asshole comment that hurt my wife. My wife, Liz, and a taller friend all walked over to my friend and I from the bar and I said "Oh look, it's the straight road, the curvy road, and the long road." It was an asshole thing to say and we got into a bad fight later. She was questioning why I would marry a petite girl if I like curvy girls, etc. My wife is about 105 lbs, 5'7" and A cup. I really love her hot frame and I love picking her up and fucking her brains out. Plus she is my soul mate and best friend.
