While I did not have unfortunate experience of a LT guy backing out after ST session, I did experienced a guy staying overnight but not willing to continue after we woke up. He kept his clothes on and refused me. Eventually, I managed to get him to jerk my morning wood away in bathroom. I still had breakfast with him after that and tipped him LT fee.
It was quite strange because before that night, we had two memorable LTs a few months earlier. But after that 3rd incomplete session, I did not off him anymore even though I still see him at bar.
