As a bull

nothing hotter then inserting the bulls cock into her pussy so yes we do enjoy that and think it is rather common in the lifestyle to "give" her to him
As a Bull, it is so good. It confirms hubby's acceptance that he is good with you fucking his wife. Just like later when he urges you to cum inside her and holds your balls as you ejaculate and then gently extracts your cock and cleans it before cleaning up her dripping pussy.
