Young wife discovered I'd given my bud her 'worn' panties

I had a brother serviceman who had a lusting for my young wife (10 yrs younger than us). She is "easy on the eyes", as he described her. 5'7", 135 lbs, blonde, blue eyes.
He'd first seen her at a veteran's picnic/dance. She was fast dancing in her crotch-cutter jeans with another wife. The rear seam of those jeans also ran right up her butt crack.....very cute and very sexy - coming AND going!
My bud commented on her, before learning that she was my wife, saying, "I'd eat a yard of her sh_t just to lick her butt!" He could be so poetic!
I told him we were married. He was pretty drunk - so he asked "does she let you lick her butt!?"
I said, "yeah she loves it - and....after she drinks two glasses of champagne ....she'll lick your butt, too!"
So....he was hot for her. He kept pestering me for a pair of her panties. "Preferably with her cunt scent in them!"
Finally - one night I remembered his request and made sure to yank them up and dig them into her moist crotch while we necked! Got all of her crotch smells in them. Then I bagged them and gave 'em to my bud.....for jacking-off purposes obviously.
A few weeks later - my wife casually mentioned her missing panties with the little red rose right over the clit area. Somehow - my expression made her very curious!
"What did you do with my panties!?"
"Aaah, geez."
"You did something with my panties? What did you do?""
"You remember Larry?"
"Yeah -your friend who's been trying to get into my pants for months! What's he got to do with my missing black panties!?"
I told her what I'd done. The whole enchilada - getting her purposely wet in them, etc., etc.!
She was furious all afternoon!
But....that night in bed - I made a play for her butt - and she pushed my hand away, saying, "What does Larry do....WHY did Larry want my panties? Why did they have to be used? Couldn't you have just taken a clean pair of bikinis out of my drawer? Why 'used'?"
"Honey....think a minute. Larry is single ever since his wife bugged out on him..Think - he has the hots for you.....now he has a pair of your panties..."
"Yeah, He has a pair of my panties that smell like me down there!!!"
"Yes honey. Think. What would he be doing with them?"
"OMG~! geez. He's doing THAT with my panties?"
"Yes honey. He's horny and you're sexy. Your panties are sexy."
She got quiet for a long time....letting me fondle her butt crack...then she said, "I guess that is kind of a weird compliment, isn't it?"
"Yes it is honey."
OK....well. See if you can get those back - they're favorites. I can give him any color he wants. Next time he's over let him look in my panty drawer. I'll wear them for him."
"Thank you!"
"Man!...guys are so friggin weird....!"
