Sexiest thing you've seen your wife do...?

Mine.
Wife agreed to play strip poker with my and 2 of my buds one night.
This was after some drinking...she came out from our bedroom where she'd prepared for bed - "to say good night" to all of us....wearing only a very short T-shirt and a new pair of lacy bikini string panties!
Her dark triangle was just visible through the panties, and she had a bit of a wedgie even with her petite tight butt!
We talked her into staying awhile - then the suggestion for strip poker.
We were amazed when she agreed - and we all stripped to just 2 items like she was wearing so she wouldn't change her mind!
Anyway - she lost, stood and slid down her panties - which caught for a second up in her pussy, lost again then Mark pulled off her T...so she was naked in short order!
We asked her to dance for us.
After a while she said she was feeling embarrassed....and "someone needs to dance with me!"
So we 3 took turns. and with each of us she eventually started kissing open-mouthed us, letting us grab and squeeze her cute butt...then she stuck her tongue in our ears and moaned, while reaching down with her hand and taking our stiff dicks, which were poking her tummy and fir...lifted her leg and put us one after another against her pussy and closed her thighs on us.
We each reacted the same way - grabbing her butt cheeks and play-fucking between her soft thighs!
She told me afterwards - that because we all were taller than her, our dicks were angled and trapped downward and were pressing and sliding wetly directly against her clit between those young thighs of hers.
Watching her grab my bud's butt and flex her hips and groin into his crotch so that his cock was gliding over her clit.....was amazing to watch...and listen to her moans into his mouth as she ground out an orgasm on each of our cocks!
Very sexy!
Each of us admitted to firing some cum onto the carpet behind her.....
