Mine was 14 years ago, my best mate had fancied jo for ages and I knew she liked him. I ran jo a bath one evening and a glass of wine and suggested to her to make sure she was tidy below. My mate had come round as planned but he thought just to have a drink. After jos bath I blindfolded her and walked her into the bedroom, that's when I nipped downstairs and told jase to go and feed his cock to jo, he was shocked but I told him its cool so within minutes she's sucking what she thought was my cock until she realises, takes off her blindfold, got a bit angry but then said be careful what you wish for before she guided him unprotected into her pussy while sucking my cock. Perfect.
