College Harem of Hairy Old Men

You finally decide on a saucy idea: you generally like older men-mostly big bears, but especially the submissive ones. You like when they are dressed femininely or scantily clad. You love to hold them close and fuck them hard. Now you've found a universe script with that as normal, in-public facet of an all-adult society. Also, everything is publicly funded to ensure everyone is living their best life economically, so university is something most people go to. Older men often go for different reason than learning.

Most men start off tops or versatile, but as they get older than 40-50, they get more submissive, bottom-leaning, and exhibitionist, wanting to get seeded by any top that consent to them. They often form close social groups with other men their age to bond over the changes to them, and to support each other in finding a partner to share. When they find someone with a magnetic charisma, big dick, and high stamina, they will decide to offer themselves to be said man's harem, to which he can choose to accept or not. Harems need constant attention, so universities (like all businesses do for top employees with private [or public for those that like to be watched] break rooms) allow even on-campus students to have a place to keep their harem and fuck them. Students with harems of five or more (including the top) have a bungalow with individual rooms, bathrooms, a kitchen, and a common room for a dorm room.

The older men are students as well, often in a pass/fail class "taught" by the top teacher's harem (though their are often bottom teachers who can do both.) Men often struggle emotionally with their new urges and often develop neuroses and exaggerated personalities in this stage of life that conflict with their submissive nature to breed. The goal of the class is to experience enough anal pleasure that they "mindbreak" and can remove their personality and become focused with being bred. This often results mental shift that make them more obedient/slutty (often sporting ahegao expressions) for their top, taking on a pet/servant mentality, or completely losing all sense of identity to become more drone/object-like (and some or all of these can combine). This lasts for 24 hours and requires the top to feed them semen until they wake up.

"Alright, I've made my decision," you tell the Goddess.

"That's wonderful. I shall now prepare to send you."

She then manifested a door that would lead to a college dorm room.

"I just want to thank you for giving me this chan-"

"You don't need to. I am not a god who rules and requires worship. I wish to serve humans because your acknowledgement is all I need to survive. Go on and live your best life."

With her reassurance, you walk through the door to a new world...

(I've been kicking around this idea for a while. This world has the Biology worldbuilding from My Own Gay Sex World, where men are born as adults from trees.)
