Your wife chuckled watching you masturbate. She knew that the freedom to be with other men would be fun but there was so much unknown delights that she discovered enjoying that freedom. Her date would be there any minute but seeing you standing there with your cum dripping through your fingers is just amazing. You're more turned on by her dating than she is. That's fine with her. She wants you to have a fulfilling relationship. Even if it is with your hand.
