No, don't show him

You can't show him a picture of your wife in her lingerie. That's for your eyes only. Besides the fact that Ariana also wouldn't like it, you don't want your best friend looking or thinking of your wife in that way. If he wants to show off his girlfriend then that's up to him and Kali, but you don't need to get into silly little competitions like that anymore. You already put a ring on your girl's finger. You have nothing to prove to anyone else.

"Wow, that's really hot. You really lucked out with this one man," you say, offering him nothing more than a smile.

"Don't I know it. I know I've been a bit flaky when it comes to women before but I really think I'm ready for something like what you and Ariana have now."

He begins to put his phone away, and you imagine that's the last you'll ever see of Kali's hot, barely clothed body.

"That's great man. Ari will be glad to hear it, she's always wanted you to add a fourth to our little group."

Matt just smiles but doesn't continue the conversation, so your attention returns to the game for now. After a while though, and another beer, you have to relieve yourself. You excuse yourself and head for the toilet. As you're heading down the hall, you notice the door into the bedroom is slightly open. You hear a sound like a soft moan. It doesn't take three guesses to figure out what's going on inside.

The question is, do you want to see it?
