I just played the update it was really good but there were just small things that bother me a bit
but else it was a good update keep up the good work
I don't mean to sound rude in any way so apologise if anything I say comes off that way but I think you skipped a lot.
Liza only squirts when the MC makes her, Bella was the one to squirt from Liza masturbating her. Liza talks to the Mc in bed about it later on and she asks him to try it on her and he does.
There is a ton of romance between the mother and MC. They go out for a meal, the opera, walk through the park and have a few conversations while cuddling.
As for the lesbian thing, when that many people are involved in a relationship they are bound to take time with each other. MC isn't the only one they love. Liza and Bella tell the MC they also have romantic feelings for each other.
As for the last part, that's not how it works. It may be a model based on the MC's penis but he has no claim of Reb's art. Models don't get a percentage of any art they pay for. They are either volunteers or get a payment upfront. Rebecca is thinking of her kids future and that's settting them up so they never have to worry about money. She's letting them live there for free i'd say that's more than generous.
