Playtime with My Client

So my client comes in today and I'm all geared up for a serious workout. But he starts telling me about this kink scene he wants to try, something Mommy-Daddy roleplay style. I thought it was just talk at first but then he asks if I'd be his Daddy for an hour. It's wild how playful and submissive he got, like a kid on Christmas morning. We agreed it would stay in the gym though, no crossing lines into anything serious.
