30 [M4A] Desperately want my wife to sleep around

Horny and wife has gone to bed, I'm looking to pass the time this evening.

I'm 30, M and from the UK. I'm bi and married to a woman. Though I do miss guys and have a cuckold fantasy of sharing my wife that I've not built up the courage to talk to her about yet.

She's only ever slept with me, so i feel like her sleeping around with a bunch of different men could be a real sexual awakening for her. Part of me wants to be involved, part wants to watch, and the other part just wants to be there when she comes home after a big session with a bigger guy. I'm not the most sexually experienced guy as it is, though we have a great time together, I feel like she needs someone who's hung and is a real stud to show her a good time really is!

We've been together for 12 years, so we've explored a lot together, so now I'm ready to take it to the next level and hopefully she is too! She's 5'4" with a great ass and amazing breasts. She's quite (needlessly) self conscious about her figure, so I feel that if she suddenly got loads of male attention it could really boost her confidence.

Keen to chat to anyone about anything, whether it be experiences, fantasies or just a regular chat.
