La Femme de Mon Pote

What are the four friends talking about “among themselves”? Of course, about women.
For example, Andre made love with his wife and with his own cousin after he found them at lesbian games. Pierre gives his insatiable wife the opportunity to meet with strangers, and Francesco first organizes a meeting with Erica for his friend, where there is "English education" and sodomy, and then goes with her to the porn cinema, where a violent orgy takes place.
