Redhead on restrained man

At first she plays with his cock bringing him pleasure, but out of nowhere comes that booted foot. He squirms in agony as she gently coaxes him to stand up straight. Once up those three inch heels whack against his balls. She does seem to wish to bring him pleasure, though, all the while taking her own where she pleases. One gets the idea that she would just have sex with him if she had no other obligation.
