I was wondering on the economics of these multi- vs. single-girl movies. There’s no doubt Kitaoka Karin is the biggest draw here as one of the most talented of her generation and somebody loved by the gods (that face!). If my perception is wrong, at the very least it’s clear the producer agreed she’s the one who’ll draw the most attention — in the cover. So why isn’t this a movie with the standard 4-5 scenes for Karin alone? I brainstormed these reasons: ROI: booking Karin costs more than the others, but just having her in the cover already gives you a bump in sales. So you pay her 1/3rd of the rate but still get a +x% boost — less than you’d get with a full movie for her, which you might not be able to do for a number of reasons…agenda: maybe Karin isn’t available for a whole day, but you can get her for less than half a day to shoot her part.combo selling: AV agencies often place multiple girls in a movie, in a deal like “you can have XXX in your movie for one scene as long as you also pick YYY”.

3 pretty schoolgirls learn to cum, thanks to the skills of 3 pro-actors.
And now, truly lovely Kitaoka Karin has been filmed in another installment in the continuing series.
Did you factor in any economies of scale there might be in continuing to film more installments of multi-idol movies, versus filming those idol filling the full running time herself movies? (Did that need lots of hyphens?)
And then there’s the beauty sleep aspect – appreciating that the girl can get tired. . . Giving her breaks, a less demanding workload, more recovery time. . . (More time for beauty sleep?)

They indeed can probably achieve some economy of scale by shooting lots of similar scenes with the same setting in a single smaller (cheaper) studio with several girls. I think the main limitation would be the male performers, hugely outnumbered by female talent. So they shoot say 6 or 7 scenes in a day in the same place. Then do so in two other studios/days. They end up with 7 3-scene movies filmed in cheaper studios that were rented only for three days overall, and achieve at least 50% savings in other production costs. Men actors are paid peanuts, and the staff are paid for 3 days of work.
The portio ポルチオ Poruchio here means the (when standing) lower part of the cervix, known as the vaginal portion of the cervix (or ectocervix), which bulges into the top of the vagina.

About those economics.
They did a first installment of the series
[PIYO-196] “I want to make you convulse with pleasure” Ultimate ‘deep climax’ development of chick girls, intimate portio sex
The site described it writing:
3 pretty schoolgirls learn to cum, thanks to the skills of 3 pro-actors.
And now, truly lovely Kitaoka Karin has been filmed in another installment in the continuing series.
Did you factor in any economies of scale there might be in continuing to film more installments of multi-idol movies, versus filming those idol filling the full running time herself movies? (Did that need lots of hyphens?)
FWIW, I’ve loved lots of multi-idol, multi skit movies. Take, for example, the whole series of series Memorial Nude Photo Session and A memorial nude photo that a loving couple would like to leave behind.” and Memorial Nude Photo Session and Cuckolding verification “I want to leave behind a beautiful naked body” and. . .
And then there’s the beauty sleep aspect – appreciating that the girl can get tired. . . Giving her breaks, a less demanding workload, more recovery time. . . (More time for beauty sleep?)
(ugh, the formatting in the list from my first message was corrupted)
They indeed can probably achieve some economy of scale by shooting lots of similar scenes with the same setting in a single smaller (cheaper) studio with several girls.

Men actors are paid peanuts, and the staff are paid for 3 days of work.

The portio ポルチオ Poruchio here means the (when standing) lower part of the cervix, known as the vaginal portion of the cervix (or ectocervix), which bulges into the top of the vagina.
In medical talk, the the cervix may divided into portions/areas including the portio supravaginalis, the cervicis uteri, and the portio vaginalis cervicis uteri
