Okay, why do you want her to go black? If she does, do you mind if she becomes addicted quickly and NEEDS a bull and his friends twice every week without fail?
Lets face it, her body is really hot with sexy hips that would turn a black bull on very powerfully.
She would definitely get the massage both externally and internally, and probably by many hands at once to give her a good "rutting". Massage is just a warmer-up to set the mood for the moment.
im on the right where ya from maybe we could go out and party. I know with my skills and you helping we could get her some bbc. If nothing else I would love to sample your wifes goodies.
