Unexpected turn of events.

Have any of you (clients or providers) been right in the middle of a session and the session make an unexpected turn? For better or worse?

Years ago I was at Spring Shower behind 333 with a girl I'd seen several times. From the first time I saw her she always provided BBBJCIM. She always remembered me and provided the same service each time I returned. One visit was going along as usual with a great BBBJ. Then she stopped and told me she really liked the BBBJ but wanted to know if I would let her do anything she wanted with me. I said, "Yes." She left the room and I started wondering what I might have gotten myself into. I kept seeing myself like Ving Rhames in Pulp Fiction with that ball in his mouth.
She came back in with a pair of very high heels on. She covered me up and took me to the table and leaned over on it with her ass up high. She guided me in for a trip to Greece. Totally unexpected pleasant surprise.

Anyone that sees me is a pleasant surprise.
