It's really hard to imagine what these people went to have such experience (like my self that I was asleep in my GF had sex with one room with two pair for a long time, and rejects the brand with the idea that girls tell the other guy)
Someone wrote in the opinion is couples traction are friends for a long time may be right, but I'm sure his previous visit was the first time the reason for switching is that they did it on the last night before leaving after by visitors especially the lady did not reveal the sex of the end of the body is not exposed.
Mrs. visiting time was much more open and dominant
These pepole can copar now proformens of eche others do not like all the other couples (if any of them was involved in a similar expirience like this befor)
It was cleat, for example, that Sasha was muce more Gentel lady guest withe
I have some thoughts on more but I think that enough for this time
