My clientele in CA were for the most part overnights or weekends. I considered an overnight 12-14 hours or so, but at that time frame, I am not watching the clock. For me, that would include dinner, possibly a show, and breakfast, with our private time progressing naturally. I always expected a good night's sleep- 7 hours- and that was never an issue with my gents. They usually needed the rest too, especially after I was done with them.

"Bust[ing] a nutt" wasn't something we "scheduled" in, but usually happened as many times as he could handle. I hate being awakened in the middle of a deep sleep for nookie, so thank goodness my gents weren't so inclined. But I adore AM sex, so I was always a wee bit disappointed if he didn't want that too (early meeting, early flight, etc.).
Have fun!!
