But what is she doing in the shower with my husband? What a slut she is!!

It's clear that in this fucking life you can't trust anyone, really anyone... you let your best friend spend a few days at home because she has had an argument with her husband and is having a bad time and it turns out that one day you come home before work and you find her in the shower with her husband and giving him a blowjob... but you son of a bitch, how do you do that to your friend?
