It has happened to me.
I came home and found 2 sets of clothes on the living room floor, along with empty wine glasses.
I stood outside the bedoom door for 20 mins listening to my wife getting fucked hard. She is a screamer and a squirter so it was quite a soundtrack.
I heard her tell him to come in her mouth, so after he did, I walked in on them and kissed her passionately.
She had not informed her lover that I may come home and that Iwould be cool with it, so he looked a little suprised.
To make him more relaxed, I told him that I wanted to fuck her well used pussy and I was so turned on that it would only take a minute.
So thats what I did, he laid there as I shot my load in her in less than 2 minutes.
With that, I got dressed, told him that he could fuck her for as long as he wanted and that I was going to walk to the bar.
2 hours later, they both came to the bar and we had a couple of drinks, then went back home and both fucked my slutty wife for hours more.
A great day!

Um
 

The first, decisive thing I would do is get a erection.

Same
 

same here! Someone else can clean up. I'm all about joining in tho!

I don't know what I would do. I believe seeing her on our bed fucking another guy would be quite a shock. Once over that initial shock I believe I'd be quite aroused and would want to see it up close.

I would definitely open the door...Depending on the reception and rapport between us I would either let him stay or kick his ass out. An arrogant cocky attitude in this case would not bode well ...but a contrite approach might just get him an extended stay and a return visit.

I join
 

I join to see

I wish!
 

That's been a fantasy of mine for years! She never wants to mix this lifestyle with our home, it always takes place in a hotel. That being said, if I heard my wife being pumped by BBC upstairs I'd figure a way to quietly crack the door open and watch her please and be pleasured by her Black friend.

mmmmmmmmmmmmm

go inside and join in

i would watch and wank then join in.
