A reverse cowgirl LoRA for Hunyuan Video. There's no trigger word as it was trained with natural language captions created with ToriiGate-v0.3, but here's an example prompt to create endless results with the ImpactWildcardProcessor ComfyUI node:

A {dark-skinned|light-skinned|pale-skinned} {curvy|slender|athletic} {asian|caucasian|white|african|arab|indian} woman with {long|short|medium} {black|brown|blonde|red|auburn|white|colored} hair and {small|medium|large|huge} {perky|drooping} breasts sits on a {couch|bed|chair|floor} straddling a {naked|clothed} man. She wears a {tank top|crop top|bikini top|bra|no shirt}, exposing her {flat|toned|flabby} stomach and navel. From the waist down she is {fully clothed|wearing underwear|completely naked}, her legs spread wide, exposing her {shaved|bushy|trimmed} {pink|brown|tan} vagina. Her breasts bounce as she {sits still|moves up and down|grinds} on the man's {hard|throbbing} {white|black|Latino} penis, which is {partially visible|fully inserted|sticking out} of her vagina. They are engaged in reverse cowgirl sex. The woman's open mouth suggests she is {moaning|gasping|screaming}. Set in a {living room|bedroom|kitchen|bathroom|outdoor location|public location|party|pool|hot tub|bed} with {modern|classic|rustic|minimalist} decor and {natural light|low lighting|candles|professional lighting|colorful lighting}.
