Thanks for this.
RCT-368 is actually has a sequel (RCT-396) in which the RCT team goes to visit one of the mothers from the contest.
Being that I don't speak Japanese and like to twist storylines to suit my interests, tastes, I have played quite a bit with both.
In one of my versions (treating both movies as one and it's sequel), I actually made RCT-396 the 1st movie, then reworked the story of RCT-368 (bikini contest) as the sequel. I think it works pretty well both ways/either way, but switching the order makes for some seriously fun kink opportunities.
In my version where 396 is first, the Mom is more reluctant and eventually falls to her son's continuous and escalating advances. It allows for her to be more of a submissive to him, rather than the victim of circumstances that happen in the bikini contest (368). It also allowed me to change/add some kinky dialog to include that she is the one mother in the contest who has already had sex with her son...and that her Dominant son also shared her with his brother. I incorporate that within the dialog between the happy, fun, enthusiastic female host and the son. She teases him to admit to the other guys that he has already nailed his hot, timid, and submissive Mom in front of the other contestant sons. I found that twist to add a lot of fun as his reactions are believable. He seems a bit shy to admit that he has claimed, and shared, his mother...but also seems to have a sense of inner satisfaction that he's accomplished something so uncommon and cool.
I've created so many variations on those two movies, on different computers/hard drives, etc. that I don't actually recall where the master files are, or which ones are actually completed or not.
I'll take a look thru and see what I can post to add to the interest in this hot mini-series.
Cheers
