We arrived along with the other couple. We were pleased to see them as they parked their car and wandered along to the house where our game was to be played.
My wife and I had never actually taken the step to swap in a foursome although we're often fantasized about it in our lovemaking. What interested us about this set-up was that it was to be done under instruction by a 'swap coach' and where the other couple were selected for us by our hosts, based on a resume we'd sent in to them.
Kate and Tom were about the same age us, were similarly attired and in good physical shape.
We entered the house and were met by our 'coach', Susan, a stunning looking woman dressed in a bulky white bath robe. She suggested we all get out of our clothes - each couple being given their own room to do so - and to then put on the robes provided for us.
Within about 5 minutes we gathered in a large bedroom with a tub chair, occupied by our coach. She stood and asked Mandy (my wife) and I to stand on one side of a 3 foot circular rug at the foot of the bed and Kate in Tom did likewise immediately opposite us.
Susan asked us men to stand behind our wives with all of us facing the centre of the rug. Some gentle music played in the background and we men were asked to run our fingers through our partners' hair and gently massage and caress their necks. Our wives were invited to turn around and kiss their men and they did so. The girls then had to face forward again and we guys were asked to gently run our hands over the outside of our wives robes touching their shoulders and moving our hands down over their chests to the bulge of their breasts under their robes. 'Erotic' hardly describes this as each couple could plainly watch what the other was doing.
I could feel Mandy pushing her butt backwards into me, rubbing herself against the front of my robe; and she could have had no doubt as to my pleasure in her doing so. We could see that Kate was doing likewise with Tom whilst watching the two of us as she did so.
After a short while, our coach asked Mandy and Kate to swap places and for us men to continue what we were doing previously, but now with our new partners. My nervousness at touching Kate soon evaporated as I saw Tom's hands moving over the outside of my Mandy's robe opposite and knew her nipples were probably hard underneath. I could feel Kate's were. Kate gyrated her hips against my crotch as I was attending to her and Mandy did likewise so that I knew she must be as aware of Tom's erection behind her as Kate was of mine.
'Coach' then suggested we guys move our hands inside the robe and so that we could touch what lay beneath. I was now, for the first time, seeing another man touch my wife's breasts, even as I was touching his wife's. The word 'arousing' hardly did it justice. Mandy, facing me, was no less enthralled see what I was doing to Kate as we smiled at each other, acknowledging the intensity of our respective pleasures at what was happening.
