Two couples swapping wives for an evening

A couple invites two more sets of swingers over for dinner one night only as part of their wife-swapping arrangement they’ve made between themselves years ago after getting tired of being single again but still wanting some excitement too! The men start off talking about sports while everyone enjoys eating together around the table until finally someone suggests playing poker or something similar which leads them outside where there are already cars waiting parked all along side each man gets paired up according to preference by his new partner who stays seated next beside theirs chatting occasionally during game time later on though nobody really goes home happy since none seem able resist trying out what happens when things get heated instead.
