The most humiliating but exciting time for us was when we met her date in a restaurant, he wanted to sit next to her at the table, I sat opposite, I could tell by her movements and occasional moans that he must be feeling her up under the table, even when the waitress took our order.
When we had finished eating, he then whispered something to my wife, she proceeded to get up and headed for the toilets, while she had gone he told me that he had booked a room in the hotel and was going to take her up to get better acquainted, but I was to pay the bill and wait 30 minutes before going up to room 15.
She returned after 10 mins and handed him something under the table, he took it off her and proceeded to open up the curled up item which turned out to be her thong, held it up for all to see, sniffed it, then handed it to me.
He then stood up, offered my wife his hand, and walked away with her hand in hand at the same time our waitress appeared with the bill, leaving me with a very red face, and a very hard cock.
