My wife and I have done it, we did a same room swap, wasn't really for us. I love seeing my wife with other men, something about seeing what turns her on from an outside perspective is hot. I thought it was so hot infact that I got distracted and didn't give the other wife as much attention as she wanted, and it made her upset. I also felt weird being with the other guys wife while he was there. Also my wife wasn't really into having other people watching her.
We're a rare couple, we're more into doing separate room swapping, but it seems like most couples only do same room swapping.
You're gorgeous, cute curvy chick with glasses that is 100% my type, also extra points for the accent. Add it all up and yes you definitely would turn me.on.
Fake Boobs, well fake anything really. For example basically all of the Kardashians, they used to be so pretty and now they all look exactly the same and like human dolls. Not shaming if it's what you want to do go for it, and I'm sure there are people that are attracted to it. Just not me.
