Arranging a massage for wife

I am a husband 45y have the fantasy of sharing my wife, exposing her body in public and also secret fantasy of cuckolding ........she is a church goer, vanilla type loyal wife and a loving mum....so convincing has not been that successful for years...she is good in bed , even i noticed she get aroused when i show her similar type porn involving wife sharing , wife cheating, and BBC stuff...yet after the session she get back to normal.....never wanted to try anything in real life......we having good sex life might be a one reason for that..

Do you guys think planning a massage during a vacation would be a good idea as a starter... any other husbands in similat stage like me? any experiences?
 
My wife used to go for a naturist 4 handed massage, it was a guy and one of his girlfriends that performed it, they were all naked and give her a tantric massage, the guy used to get aroused and she would end up with his cock in her mouth, the girl would bring my wife to orgasm, he would then fuck her and shoot his load inside her pussy, my wife would then open her legs while his spunk oozed out of her. She lived it, sadly the masseurs moved away.
