Reading your other posts, I am sure that your hubby is ready to enjoy seeing you being pleasured by another man and seeing how you react to a big cock on a man that knows how to give you the orgasm you crave.
Being free to jerk and cum can be very distracting for the wife and her lover, so he should be caged. Her pleasure should not be interrupted and hubby should learn to get his pleasure from seeing her enjoying her lover, and her orgasms.
