Wives waiting for their bulls.

You have written about cuckold interactions and I have a question.

We have done a few things like guiding, cleaning and a bit of fucklicking.

My wife has a friend that as the pics show is quite hung.

After he got done pleasuring her he told me that we should do a 'cuckold threesome'. We have been at this for a while but he is more experienced.

What is involved with a cuckold threesome?
I always thought that a cuckold 3some was when hubby is underneath in a 69 position and I fucked the wife doggy, but when I ejaculated I pulled out and unloaded in hubby's mouth. Everybody wins.
