How many wives invite men to there place to play in front of there husbands?

We often played at home but almost never with strangers/first timers...almost. Fucking others in our own bed has always been something we do.

People we know well spending the night or weekend happens

Back in our younger days had one friend live with us for 3 months. Evolved from just letting a friend stay in the spare room, to doing MFM within a week or so, to her sometimes sleeping in the spare with him, to all 3 of us sleeping in the king in our bedroom.
