A few years ago my wife was away visiting relatives for a couple of weeks. When she's away I like to engage the services of local prostitutes. Unfortunately my favourite wasn't available and they sent another woman. She arrived on time and I opened the door totally naked. Imagine my surprise and hers too as it was a girl I'd taught in school the previous year. My semi-erect penis rose fully to attention as I enjoyed strutting around naked in front of her. I gave her a glass of wine to relax then she stripped off for a great fuck session. I gave her a bit of extra cash for her embarrassment.
