The day before leaving we spent time putting together a sexy outfit for Mrs Curious to wear under her vanilla clothes. She chose a black lace bra and panty set from Victoria Secret, then covered it with a sheer black body suit that hugged her tight. This had snaps in the crotch which I had the pleasure of assisting with.

We left the room to meet for dinner at a brewery, and once again we arrived slightly before they did. When they walked in we all greeted each other like old friends. The feeling was very comfortable and we were totally at ease with them. We all ordered drinks, had dinner and talked for about an hour then we agreed that it was time to head back to the room. We poured a glass of wine for everyone except for the other man since he'd be driving home later, then turned on some music and sat down to listen to a story that my wife had written for him. We learned during our last visit that he enjoys hearing of past experiences and other stories, so she crafted an intriguing little tale involving 2 couples and BDSM.

The other woman returned wearing a very sexy bra & panty set that left little to the imagination and walked over to where I was standing while he approached my wife and kissed her. Within a very short time, they disappeared from the sitting room without making a sound. I did not see them leave as I was busy

Later, my wife shared with me some details of her fun...
When they got to the bedroom, he caressed her body as he removed the lingerie that she was wearing. While they kissed she helped him to undress, then she kneeled down to take him into her mouth. When he was fully erect, she placed a condom on his cock which then quickly softened and never regained it's hardness. He apologized sincerely, then turned his focus onto her body. He played with her heavy tits, rolling her nipples while kissing her lips deeply. Then he asked for permission to go down on her pussy. She laughed and said "Uh, YEAH!!" He moved down her body, placed himself between her legs and gave her his very best tongue lashing. She says that it's hard to describe what he did, but that it was VERY good and gave her a long rolling orgasm. When she came down from her high, they laid on the bed and talked for a while. They peaked out a couple of times to see what was going on in the sitting room, then eventually came out to join us.
Meanwhile, myself and the other woman were dealing with a similar situation where my cock didn't cooperate either. I did my very best to please her in the other manners that I know, and I'm sure that she orgasmed several times.
When the evening was coming to an end, they dressed and we walked them to the elevator and said goodbye. We've traded dozens of text messages since, all positive and indicative of future fun. One of these times our ladies will actually get fucked!
