I'd love to do such a movie, but I have to be boringly pragmatic and note that the cost of production grows with each female performer added, and I'm not sure that people are willing to pay 2x for the movie in order to get 2x the cast.
There's no need to feature the
entire ensemble in each movie. To use Bearing Gifts as an example, even though the main character has a rather sizable army of hot, hypnotized sex slave, we see at most three girls per chapter. A continuation of Bottled could follow Brooklyn and Ash's list of recommendations. We could see Ash with girls from her school to give an example.
Now, Bottled may not be the ideal story for this as plot forces Alex to be there and driving up cost.
