It's been trending lately, huh? A private gym with completely private rooms! It seems like you can commit to results! There are busy wives with big butts who are bored with going to such gyms! While training, they stare too much at the young instructor's plump crotch and can't even follow the lesson properly! Before long, they gradually get excited and want to insert their penis, so despite being in the middle of a lesson, they ended up having more than 10 orgasms!
