The funny thing about your wife's acceptance cuckolding you with other men is how she is incredibly hotter and irresistible to you now. Especially when you both are in public. Her sexiness oozes from her and other men see. The result for you is an infinitely more intoxicating woman who when you gaze at her form you crave her more than ever because other men enjoy her.
The great thing about being cuckolded is knowing your wife is motivated to enjoy other men. She eagerly, and hungrily, pursues men no matter where she is. That keeps you motivated as her cuck. It's exciting just being in public with your wife.
