Hi,
Me and wife have been married for nearly 10 years. Since some time me I have had a fantasy of having this MMF threesome scenario. I once brought this up last year and she was not happy. But recently she has seemed to open up a bit and giving hints about threesome in our casual conversation. Using of dildo while sex and DP using dildo.
I am wondering if she also wanting a threesome and giving me an hint! Bit nervous to ask.
Would you say it is?
Good luck with this and I’m going to watch this keenly as I want to have a think with my wife
None of us know your wife and all we can do is speculate. You’ll never know unless you ask her.
There are many other topics here on threesomes use the spyglass to search for them.
One thing everyone here has not said and I would have listed as top no no, is just find a guy at the pub and bring him home.
I’d suggest you talk to your OH about her suggestion:
“… recently she has seemed to open up a bit and giving hints about threesome in our casual conversation. Using of dildo while sex and DP using dildo.”
You could remind her during an intimate moment and ask her if she could elaborate in order to ascertain what she would like. What is paramount in this is her decision: her acceptance (or rejection) of her participation in what has been suggested. She will need to feel comfortable about going forward with the next step and require lots of reassurance.
Involve her in the choice of dildo you might be considering using for DP in order to ascertain what she would be comfortable with.There are double didos specifically designed for DP.
Perhaps you could broach the idea of you using a strap-on dildo as an aid to DP?
I often use a strap-on for the purpose of using it for DP to replicate a threesome without the introduction of a “third wheel” into the bedroom. For us, this is much safer (and less intrusive) than having to invite a third person
There are many unisex harness designs for sale on LH. I find that I am able to use both my penis and dildo for hands-free DP in this manner.
Dildo is totally different than adding and extra person in the mix
As @Gareth said none of us know your wife to say for certain. She may be opening up to the idea, or she maay just be willing to talk about it because she knows it turns you on. If she is opening up to it, the one thing not to do is rush her. She needs to feel like your priority, not your fantasy. Good luck to you both 
Only way to find out is by asking ! 
Would love a threesome with 2 guys and I am dressed as the woman always wanted to be a woman and enjoy the thought of having a man in my ass while I enjoy his hard cock in my mouth
@Fent10 My fantasy 
I am so keen to dress in my tight little panties, stockings and heels and do just as you have described.
Maybe just ask again? Make sure they are hints and not your overthinking/subconscious though.
