Looking for someone to write a story

Hi, I'm looking for someone to write a story with these themes: Size Comparison, SPH, Grower, Family (Mother, Sister, Aunt).

Story context: A vacation at a resort without knowing it was a nudist resort, a vacation where two completely different brothers end up having painful experiences in their testicles because of their family.

I'm not looking for a short story, but one that covers a whole day at that resort. I want to see how that day ends, and if I like it, I'd like six more stories covering the entire stay at that resort.

Anyone interested?
