Here are the stats at the end of the first part. So basically having sex with Inoda was the last thing before the second part. And there was no sex between the two parts.

I'm sorry that it's in a different language, but the first lines are lust and sex, orgasm, masturbation, etc. That is, at the end of the first part sex - 19 orgasm - 27, and at the beginning of the second part sex - 19, orgasm - 27. It's a good question about how much time has passed between the parts, to be honest, I don't remember the dates being specified in the first part. But I don't think much, I'll take a few days, or maybe just 1 or 2 days.
