Is it normal that my husband took a cock in his ass

My husband talked me into having sex with a guy this past weekend. My husband watched. When he was done with me, he asked my husband if he wanted some. My husband shrugged his shoulders. The guy said, "That means yes". My husband was naked and the guy throws my husband on the bed. He's holding my husband down and pounds his ass harder than he did me, and goes for awhile. My husband just looks limp but enjoying it. While the guy is pounding him, he says, "damn, you are taking my dick like a bitch. You and your wife are my new bitches now". He cums all in his ass. My husband has never done anything with a man. I don't know if I'm perverted or not, but I was enjoying seeing him get his ass pounded.
