Three: By Invitation Only

A sexy woman, a nameless man; she picks him up, as her husband watches, then she invites the new man to enjoy sex with them in their wealthy suburban home. Swingers, three-way sex, and more.

Since they met in college; he likes to watch her have sex with others, she likes sharing him and being shared with friends and strangers; but so much play can lead to troubles and broken friends and breaking the rules when your lovemaking can build new relationships or destroy lives.
