Ugh imagine being a woman with a muscular body who has sex with fat old men for lots of money. Disgusting.
@Jazzy_Butts personal trainer using sex as a reward to turn fat old men into fit old men. Like, they're technically getting paid to be a personal trainer, like how a pornstar is technically getting paid to act/get filmed. But we all know they really getting paid to fuck. Keep up with your diet or exercise, you can beat off while she's changing. Both and you get a handy/beej. Go above and beyond, maybe beat her at something and you can put it wherever you want.
@Jazzy_Butts and the best part is that they'd start to associate healthy habits and muscle gain with busting fat nuts, so they'd be doubly motivated to try to make themselves fit as a fiddle. Maybe more wiry cougar-twink than beefy gymrat, but still fat to nonfat via sex with fit lady.
@Sudodeme Tbh this is what happened with my ex kind of. They would use sex as a reward to get me to go out and be social with them. Then at the end of the night I got to fuck.
Unless I'm the fat old guy then it's ok
