Two couples try a night of swinging in one of their places, but only the wives end up fucking each other. A soon-to-be bride comes back to a swingers club to get her engagement ring back and finds out that she had sex with a bartender last night. She fucks him again.
Following instructions from a note which she thinks is from her lover, a wife blindfolds and chains herself on a bed inside a hotel room. Someone comes in, fucks her aggresively, and then comes out without her seeing who he is. Was he her lover or someone else?
