The Swap # 2

John Dough is married to Lene Hefner. He wants more than the vanilla sex he encounters with his wife. John and Lene are friends with Leena and Marc Wallace. Leena is adventurous and exhibitionistic. She and John wind up going to a swinger's orgy to see if the swinger's lifestyle is for them. Meanwhile, their spouses are left alone to wait and ponder the fate of their marriage. Is it what they expected and can the experience bring them closer or will it tear them apart.
