My boyfriend was the first one to ever fuck my husband and it was while my husband was fucking me. It was really super hot and I liked it more than my husband did. My husband fucked my boyfriend a few times too, but for many years now my husband is the one getting fucked.
Some very dominant or more aggressive bulls love to fuck my husband or to see me peg him. I think it is a power trip for them to not only take a man's wife in front of him but also take the man's ass. I have two bulls who insist my husband wear sexy panties and give them his ass when they want it.
