Crossdressing turned into sex with wifes b/f

I had just been building a retaining wall and was hot and sweaty and decided to have a shower when i got out I realised all my clean clothes were upstairs. I looked thru the washing hamper and found a red pair of my wifes panties and a satin robe i quickly put them on and started up stairs.
My wife arrived home at that exact minute with her new best friend. I stood there absolutley speechless.
My wife looked at her friend and asked her what she should do. Her friend gave a sexy smile walked over and dropped to her knees and took me in her mouth.................... the rest is history.
I now always shower downstairs especially if I know the two sexiest ladies in my life are about to to come home.
