I Thought She Meant Work

Txt: Hi Derek. I’m texting you this picture of your missus this afternoon at my apartment. She makes the perfect PA don’t you think? 

Txt:  Is that my Wife taking her top off? 

Txt:  Of course! We were just off to bed. 

Txt:  What do you mean? 

Txt:  She’s my Mistress. I thought you knew. 

Txt:  Oh my God! You have made me a cuckold. 

Txt:  Sorry Mate, but you’ve been one for years. I’m surprised you never guessed, given the number of times she has stayed over at my place. 

Txt:  She always said that you were both ‘hard at it’. I thought she meant work. 

Txt:  That too sometimes.
