Swinger party turns into a full orgy with sexy black guys

Every two weeks they got together with their best friends, they were a group of couples who enjoyed their bodies without guilt.  They were what is called swinger, they shared with each other their partners, they had all been through it all, both girls and men. They knew all the dark secrets of the group. However there was a limit that they had not wanted to cross, the idea of a total orgy held them back before the idea of a raving of pleasure that they did not believe they could tolerate. However, the day came, the alcohol had helped and now they were all naked and fucking like never before.
