The cleaning of you both afterwards is such an important duty. It allows you and your lover to relax in each others arms and chat while hubby carries out his job.
Once he accepts his role it is better for all. His role is to suck and clean cock and cleanup freshly fucked pussy. This leaves you and you lover to get on an enjoy raw sex.
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.
