Happy New Year!

So its new years eve and 3am right now, I had my best friend over, his pregnant fiancé and a few other couples. everyone was drinking having a good time (besides the pregnant women) my best friend had a few grams of coke and was doing some sneaky lines in my garage as everyone at the party would have frowned upon that especially since he has a pregnant fiancé! and if my wife knew that was going on she would have lost it, as she's never done d**gs in her life and has been fully against them, until tonight...... it hit about 1am and most the couples left, my best friends fiancé was asleep on our couch as I imagine being near full term would be exhausting.... the party started around 6 hours prior mind you, I hadn't seen my friend or my wife, and we have a pretty open relationship as you can read from previous posts.... but I've always told her my best friend was off the market in that scenario, I've always know she's thought he was quite attractive, after cleaning up the house I was looking around for them, and what happens next had me some what feeling half torn, I could hear giggling so i popped my head around the corner of the door to look in and what do i see.....my wife snorting a line of coke off my best friends rock hard cock, she then licked the rest off and started sucking his knob. Normally I'm fully into my wife doing what she wants, however this time I couldn't watch I just walked off half shattered and sat down on the lounge and pretended to watch the movie showing, they were back out with us within 10 minutes or so, not long after his fiancé sort of woke up and they decided to leave, my wife has since gone to bed and neither suspect I know a thing... :/
