My wife and I hosted a dinner party for 10 of our closest couple friends--either married or BF-GF. She's an exceptional cook, so everyone always enjoys coming over for our dinners and it gets very festive with lots of great wine and sharing some fun, crazy stories and inside jokes.

Anyway, a little background: My wife Nina is 5-11, thin, big, full boobs and beautiful blowjob lips. She always gets lots of looks and enjoys the attention. We have an open marriage (well, she does--she's been fucking my buddy Preston on and off for a while now) so it's not unusual for her to disappear for a few minutes even when there's company, to give him a quick blowjob or for him to fingerfuck her pussy at these types of events. So I didn't even think twice when Preston got up from the table to join Nina in preparing some of the food for the next course.

It was time for dessert and Nina and Preston both came into the long dining room each holding a desert in their arms--Nina an apple crumble pie and Preston behind her with a plate of powdered sugar flourless torte. All the laughing and talking stopped when they walked in--Nina's black shirt had hand prints made of powdered sugar on her boobs, which really stood out on her black sweater. She didn't even know what everyone was looking at until Tina, our very boisterous divorced friend said "Um, Nina, you have a little something" and motioned to her boobs. Nina looked down and her face turned completely red and I'm pretty sure that all of our closest friends now know that she fucks around. I tried to fix it by saying that powdered sugar flies everywhere, but the damage was done. She went into the kitchen to wash herself off while Preston sat down. There was utter silence with a lot of dirty looks from the wives and some smirks from the guys. Nina ended up spilling the beans to her girlfriends after everyone got home. I don't know how I am going to react if any of these friends mention anything in front of me. It's one thing to let Nina have her fun'; it's another for everyone to know that I'm a cuck.
