My wife's first Bi experience was during a sailing holiday in Greece. We were part of a floatilla and for one reason or another we got on very well with the crew of the lead boat, one of whom was Rosie, a 24 year old, live wire with a great personality and a great figure. One evening she had a drunken argument with her skipper after which she was very upset and my wife Sarah, whilst comforting her, gave her plenty of hugs and told her she could sleep on our boat if she wanted.
A little later the three of us staggered back to our boat and had a final drink as we all chatted and when Rosie took herself off to get some things from her boat I pointed out to Sarah that she hadn't exactly thought the sleeping arrangement through as we only had one bed. Possibly seeing my excitement at the potential of being in a bed with a scantily clad Rosie she announced that it would be fine, Rosie would sleep on one side and me on the other with her being in the middle.
Part way through the evening I woke to the sound of Sarah softly moaning and looking across in the dim light I could just make out Rosie's face looking down at Sarah as she gently caressed her body. I propped myself up and saw Sarah actually had her eyes closed. Rosie looked shocked but I smiled and unbuttoned Sarah's nightshirt ******** her D cup breasts whispering to Rosie it was ok to carry on.
Sarah groaned a little more and Rosie and I began to suck on Sarah's nipples. I fingered Sarah's pussy and found she was soaking wet down there and as I rubbed her a little harder she opened her eyes and initially gasped in horror as she realised that Rosie was actually sucking her nipple. I smiled at her ant told her it was OK and she just flopped her head back and grabbed the back of Rosie's head pressing it hard against her breast and moaning more for a few minutes before she then began to push Rosie's head down towards her pussy.
Rosie licked and sucked on Sarah's pussy for a few minutes and eventually brought her to a huge orgasm following which she drifted back off to a sleep. The following morning I woke and the two of them were both butt naked, curled up together. I made coffee and woke them at which time Sarah seemed embarrassed at what had happened but I told her it was fine, Rosie gave her a kiss and we all got on with the day and the rest of the holiday just putting it down to a drunken event.
