The reply you dreamed of
Mate i feel for you and as i have just met my new gf who is incredibly hot, liberated, and down right dirty i am sending over to you. She isn't really into huge dicks as she likes to make sure she can take it all but she has consented to allow you to use her at your whim until such time as oyur wife "understands" you better.
When you're bored with her she will call her bi gf to help her. Once you are over your predicament then send her home to me mate.
Or rather
Have you spoke to your wife and asked her what you can do to make your marriahe work?
oops sorry
