Went back for another go with Linda today, and am happy to report that Monday's pleasurable experience was not a one-off.
Also got a taste today.
I was so enthusiastic that the show finished early. Post-O haze prevented me from realizing that, and there was no clock in the room (usually a good thing). A bit of post-O head and neck massage, she helped me get dressed, and once out the door I realized that only 40 minutes had elapsed. Would have been nice to entertain me through the full hour, but overall had a good time.
