NOT true at all. I've had some of my BEST sessions at night, usually stay extra time, well past the hour, have drinks with them, sometimes take them home, so NO, not true at all. But I did find the solution for when it comes to Hime, I saw Yazumi at XOXO instead of the possible repeat and it was way better for the same price. Hime is nice, but I don't think she merits the $40 hike she had pre JAV.
Agree with bx here, even though im not nearly as charming as he is.
As a married guy, I dont have the opportunity to get the last session very often. But I've had a few. It can go either way, so there's probably higher variance. But on balance, I love that last session, especially with a repeat girl. Sometimes the girl is tired, and I've had a dud or two, true, but more often, I get a more intimate unrushed ssssion. Ive had, with no upcharge, up to an extra 30-40 minutes, and almost always they at least define 60 minutes as excluding shower/dressing time in that last slot. More importantly, the girl often can let herself go more freely. Some are able to hold back their own orgasms during the day, because yeah, it can be exhausting. No need for that in that last session. With, in my experience, some amazing results. Less important, but wirth noting, they also can be more relaxed about preserving their hair and make up for those of you who want to do things that will mess with their hair and make up.
Moral of the story, if you're going late, you definitely dont want the next-to-last slot.
