At the company party your wife mention how good looking your co-worker Bob looked. You coyly asked her, "Would you fuck him you had the chance"?
She giggled and said "Hell yeah".
During the next two weeks at work you brought up the subject to Bob about Swinging and Hotwifing. Bob did seem a little surprised when you suggested a 3 way with your wife. When Bob made sure you weren't joking he asked how this would work.
"Come over for dinner next Sat. I'm not telling Linda what's going to happen. I want it to be a surprise for her. After dinner maybe some wine in the living room. At some point I'll get a little romantic with her. I'll start to unbutton her top. That's when you join in and help me. Suck on her tits, unbutton her pants. She's going to melt. When I get her on the couch, really take charge. No condoms. I'm going to hold onto her as you're fucking her. I want her to know that I gave away her pussy and watched as another guys used it. Really work that snatch, I want her to know she's a cum dumpster for random dick. After you cum in her, I'm going to have her suck my cock. She loves the feeling of being sexually exhausted afterwards."
