And I love you for that.
Prepare yourself for the best sex you've ever had. I'll tell you how to rev him up. Tie him down. Cage his cock. Put a strap-on over it. Lube the strap-on and give it the best handjob you've ever given. Make him strain so hard that his locked cock could fucking break in there. Then untie him. Say you've been a bad, BAD girl and need to be punished. Just don't give the key back.
Your wife embraced the freedom to be with other men when you expressed a need to be her cuck. She thought it was the hottest concept, especially when you remain devoted to her. As beach people she's forever wearing thong bathing suits and gets plenty of arousing looks from other men there. That's why she enjoys walks alone. More men will approach her when she walks alone wearing thong bathing suits. And she enjoys the seduction. You don't mind. It leads to her enjoying them where you can watch.
