Here are a few ideas I've had. Happy to chat about modifying, combining parts, or using some of the themes for something else.

A different kind of rodeo

I run a dude ranch that caters to gay men who want a full Western experience. However, the animals on the ranch are giant men who act live livestock. When they’re horny, they’re a handful and pretty wild. You've either heard this through word of mouth and are curious or you have no clue what you're getting into.

(Alternate: mythical creatures like centaurs instead of giant men.)

Brainwashing the farmhand

We both work on a farm. You’re huge in every way–tall, muscular, hung. I’m reasonable fit and strong myself, but I look tiny by comparison. I’ve sometimes teased you that you’re like the human version of one of our bulls or a stallion. You joke back that like them, you like to breed and are a handful.

I’ve secretly been trying to hypnotize you and make you into an actual animal. Things have been going well. I’m just to the point where I’m going to choose your persona–the bull or the stallion.

Island of giants (or centaurs)

Legend has it that there is an island inhabited by feral, muscular men with a musk so powerful, those who inhale it immediately want to please the men sexually. The legend also says that no one has ever returned from visiting--either becoming sex slaves to the men or dying from overuse. We set out to explore the island and actually return to tell the tale.

(Alternate: centaurs instead of men.)

Kinks: sweat, musk, harnesses, jockstraps, armpits, nipples, restraints, muscles, big cocks/ balls, public, cum, outdoors (open to plenty of others too)

Not a big fan of: piss/ ws

Limits: Scat, vomit, gore, vore, anything underage

I like to play first person and generally like at least a few sentences in the reply. Playing in DMs here is preferable.
