Whether you are married, boyfriend/girlfriend, or any other combination, sooner or later your curiosity will turn toward involving other people in your sexual relationship. It is simply human nature to wonder what it would be like to have an extra man, or an extra woman, or another couple to play with. Your only limitations are your imagination and your tolerance. If you want to set up a gangbang for your wife and invite 6 strange men to participate that just shows that you love her a lot and that you enjoy watching. If you decide to do that, better invite about 12 because men can be nervous about their performance and, in my experience, only about half will show up. More will come if you provide beer and pizza, but I digress.
Adding a stranger or another couple is by far the most common experiment, and that can go extremely well or it can be a terrible experience depending upon how well you screen your extra people. Make sure that your desires and limitations are in line with others before you invite them over. The ranks of swinging couples are filled with "drama queens & kings" who can take a pleasant evening and turn it into an episode of "love on the rocks". With the right people, it can make for an evening of combinations that you have fantasized about and fantasies fulfilled.
These stories offer a variety of sexual combinations involving everyday people just like those around us. That guy you meet in a bar could be the one who can excite and entertain your wife while the two of you make love to her. Your wife's female co-worker could be the one who teaches your wife how girls play together, then they both invite you to join. This book is more about couples adding a third than it is about heavy-duty swinging. If you have ever been involved in such an activity, you know exactly how much fun it can be. If you have not done it but fantasize about it, this book will give you a glimpse into how things can happen.
