Show And Touch

My wife's almost ten years younger than I am and is a very strikingly beautiful Taiwanese. She has jet black hair and a trimmed but unshaven puss.
She likes her rum and gets very sexually excited when she drinks. Being she's only about 88 lbs. she gets pretty frisky with just one or two drinks.
About a year ago, just before all the covid stuff hit the fan, we were at a party given by a company I do business with. Mai had three or four drinks and was feeling good, but tipsy so I took her into the spare bedroom and laid her down for a nap.
She fell asleep on her tummy very quickly and the sight of her dress hiked up and her gee string panties being just a single thread deep in her crack made it look like she had no panties on at all. I decided to leave her like that and if anyone went into the room, they'd see her essentially naked arse.
Maybe a half hour later I took one of the hosts into the room to "check on" my wife. This fellow David got some eyeful, but not as much as he was going to get.
I shook Mai a little to be sure she was deeply asleep and then spread her arsecheeks wide and showed him her tiny hairy arsehole. I wet my finger with some spit and slipped it in her bottom, then invited him to try. He sucked his finger to wet it and slipped it very, very slowly and very, very deeply into my wife's arse. So deeply that when he ever so slowly slipped it back out the first digit of his finger was dirty.
We both had tremendous stiffies and I was tempted to tell him to wank off onto her but didn't think we should press our luck.
Ever since that time, whenever I see or speak with Dave he always makes a motion as if he's smelling his finger and asks how my lovely wife is doing.
