Oh ya if she is onboard for teasing the old guy this is going to be way more fun! Sounds like she needs a micro bikini she can wear in the yard and him see, or a thong bikini ideally with the lining cut out of it. Short skirt without panties is a gold mine, even if she isnt bols enough then with a hot thong panty and commit to bending over at the waist and give him a full moon view. But including her bare shaven pussy in that would would be better as long as she plays it off as an oops

She is absolutely gorgeous! I really like the idea of her wearing a loose top, no bra, and bending over absent mindedly in front of him. If she’s down for that you have it made, plus it would be a thrill for all three of you.
If not, the accidental picture texting or scrolling is your best bet. If you laugh it off and act like it was an oops, but no big deal, it may get him to talk to you about it, which can be fun and can lead to more picture sharing.

The biggest disadvantage of "oops" moments is that they can only happen once, and then the fun is over.
My advice: Start sharing photos with your neighbor regularly. While discussing last weekend, show a few photos from it, and continue doing so over time. Keep it casual—nothing nude, just everyday clothed photos. Gradually make the photos more interesting: your wife in a new dress you bought her, bikini shots from a vacation, then slightly more revealing bikini photos, or her sunbathing topless while lying on her front, perhaps showing a hint of sideboob later. Over time, as he becomes accustomed to seeing some skin, you can include a photo of her sunbathing topless on her back in the next set. Act nonchalant—don’t comment on it, treat it like any other photo, and move on to the others. If he remarks on it, respond casually: “Yeah, we don’t like tan lines; she often sunbathes topless.” By doing this consistently, you can eventually share more revealing photos on a regular basis and keep the fun going.

Can he see her bedroom or bathroom windows from his place? She could strip at the window, making it look 'accidental'. Lots of women like to do this.

Thanks :-)
 

Thanks for all the nice comments and great suggestions guys! Looks like the phone is the way to go then for now! Only problem is he doesn’t have a mobile phone, so I’ll have to show him something on mine!…

Post them on here
 

I’ll make sure I post any of the pictures he sees on here! :-). I still need to think of the best way of doing this!…

Yes, this is the way most of my friends show me their photos. But I bet that if you say after while: "It's pity you don't have a smartphone. I would send you some photos time to time." He will buy smartphone the day after.

My ideas...
 

How open-minded is your wife?

Ask her to walk around the apartment naked so he can see her through the (open) windows. Try your wife to bend over in front of him wearing a low-cut top without a bra. He's guaranteed to look. Or, while bending over, show her butt under her extremely short miniskirt... She can leave the panties off.

And just ask your wife if you can show him a few photos of her breasts or pussy. If she says yes, all three of you can have fun. If she says no, show him the photos anyway, and both of you men can have fun, and she won't suspect anything...

Only just worked out how to reply to more than one post! Yes I can see him wanting to get a phone if he knows it’s possible he will see my girl more!

These are great ideas! First option is not possible unless she has had a fair few drinks haha. She will do anything for me but she is quite reserved and dresses proper around other people, although she does get a bit naughty when she has had one too many!

This is definitely the best option, just not sure how to show him my phone yet without it being obvious, because he barely knows how to use one, maybe he could swipe through images and there is one in there he wasn’t supposed to see. He has good eyesight and wears glasses so he will definitely get a good look!

More pics! Hope you all like!
 

I can only get on here every 2-3 days due to work. My posts are getting reviewed at moment each time I post. :D
