Make sure your wife gets her wish every week from now on. Buy her some nice new clothes to make her feel really sexy for her bulls...and help with her bath or shower, and brush her hair, and lay out her new clothes. Start doing a lot of housework to show you really care about her dreams.
For your wife to enjoy dating with BBC, you must lighten her workload, so her libido will lift dramatically to match the powerful pelvic thrusts of the black bulls.
Make sure she has many dates WITHOUT you watching her. Actually, being allowed to watch her bull fuck her, is a reward for you making a good job of the housework. If you watch too often, you won't adequately appreciate the reward.
