Serious question due to suspicion

Could be she's cheating, so you should keep an eye on her used panties. They never lie. Open a GPS tracker on her cell phone and it will tell you more than you need to know. Just be ready to how you will react.

Loose pussy is not enough evidence. What about changes to how she smells, changes in showering routine, secrecy, etc.?

Loose pussy can be due to lack of kegel exercise, dick getting smaller, etc.

Or a large dildo

Does it matter to you if she is cheating?

Not sufficient. It could be a disease not linked to sexual activities.

You are on a cuckolding site. To me that means bayou are interested in it. So if she is cuckolding you the only reason I see for calling it cheating is the lack of communications about it. (I am leaving Jeff's wife out of the equation for now.) But when you are playing your fantasy games you might start putting in that it would be HOT for you if it the scenario us she is giving you as fantasy were really happening.

In short some communication needed here.

It always comes as a surprise when it does actually happen the first time. Run with it, see what happens, but don't push her too hard. If you genuinely want this to be a reality then you have to cut her some slack, and bring Jeff more into your 'fantasy' scenario's. Keep us posted, this could be the beginning of a long and pleasurable journey for you.

Lickingpike : that's good advice, as is what Fantmstr says about more communication being required. I spent the best part of 2 years gently encouraging and persuading my wife that I'd be turned on by her having sex with someone else. We used a dildo as the cock of another guy and we fantasised about me catching her and not stopping her, but watching instead as this stranger's cock went in and out of my wife's pussy.

When it finally happened it wasn't how I expected because you can't control how your wife is going to play it or react nor the other guy. Though very aroused knowing she'd been fucked, the "cuckold angst" of jealousy and insecurity overwhelmed me and we stopped for over 9 years!

Maybe you were meant to find the wallet? Maybe your wife isn't sure how you'll react to knowing Jeff is actually fucking her? Maybe it's a bit too close to home? You need to talk, but don't make the mistake I made and let any insecurity cloud your judgement. You wanted this and it's highly likely she has indeed cuckolded you. As Kenny says, run with it - gently, and try to enjoy it. Don't make her feel guilty. Praise her. Re-assure her that you still love her, probably even more now. It will be worth it. Good luck.

Sounds like Jeff's wife is very supportive of her hubby sharing his big cock. Maybe that's why she told your wife about Jeff's big cock?

Enjoy how her loose pussy is feeling and let her know your cock is enjoying the feeling. During story time, plant the seed that you would love to taste Jeff's cum from her hot pussy. See where that goes and what her response is.
Cuck who loves a creampie.

That second picture looks like her pussy has been re-sized.

I am very happy that you two have opened a channel of communication. I wonder how long she will go from not telling you to announcing she will be home late because she will be with him or having you help prepare her for her date.

Enjoy the ride. It has just started.

That was probably what she was worried about. She'll be relieved that you're willing to accept it. My wife and I never called it "cheating" or "being unfaithful" as I actively encouraged her to enjoy a bit of extra cock elsewhere from time to time. we just called it being "naughty".

I bet Greg is well pleased with himself having fucked 2 local married women. I take it Jeff doesn't know his wife has had some? Who had Greg first? Jeff's wife or yours? I wonder if the two wives have compared notes on Greg's size and sexual prowess? And will your lady confide in Jeff's wife that you are know fully aware and agreeable to her "affair"? Jeff's wife may now start smirking at you with a knowing look.

Well done though for handling this so well and getting her to talk about this. It's no doubt a relief for you both to have this out in the open. When my wife had her first "adventure" I got very insecure a couple of days later, but you must fight that "cuckold angst" and go with it. Things are never quite the same again once your wife has opened her legs for another man, but you can certainly both enjoy this new shift in your relationship. If you two are strong and trust one another, it will make your marriage even stronger. Enjoy!
