Married guy wants a shemale to fuck his wife

I'm a married guy and I've had this fantasy of a shemale fucking my wife for quite some time! She is a very attractive lady. She has been hesitant in the past to try new, kinky things, however, lately, she has begun to get into what initially was my self-imposed chastity. However, she quickly shoots down any attempts at my trying to bring up her having sex with real tranny

I'm just looking for suggestions, because i know that she would be much happier if she had a real tranny with a huge she-cock, pleasing her. And I know I'd be in heaven serving the both of them, sucking her big shemale cock and cleaning my wife's pussy after she creampies her.
