I heard my wife being fucked by her boss at a Christmas party. She showed me what she was wearing before she left for the party, a really sexy black evening gown with a massive split, and I noticed she had packed a new pair of stockings, suspenders and matching black sexy underwear and she shaved her pussy before she left so I was a little suspicious. She was staying in a hotel, and after the party she called me to tell me she had got back to her room safely and was on her own, but forgot to end the call because she was drunk. I carried on listening and heard her door being knocked, she let her boss in, and I hear them kissing. I heard him tell her he hadn't got any condoms and she said don;t worry I want you to cum inside me. I heard them fucking for about 30 minutes - she was screaming in ecstasy as he fucked her. He then left and I ended the call.
