You play a prisoner and are alone in the prison gym working out in your sports bra and yoga pants all hot and sweaty. You can't help but notice the guard keeps peeking at your sweaty armpits. You are super horny from being locked in a cell all day for years so get into a really dirty and flirty JOI for special privileges of course! You make a deal with the guard to give you some more freedom/workout time whilst letting him jerk off for your sweaty armpits. Focus on armpits with sniffing and licking and giving JOI throughout.
