One day of sexual marionette teaching wasn't enough for this hump crazed masochist, so day Four starts with her working on her oral skills. She has improved on her spear sucking abilities enough that we sense that it's time to make her earn her grade for humping.
We begin the next workout that will have her using every ounce of strength to get through. She is made to ride cock until her legs give out and then made to do it more. She wants to be a service breezy then she will do it on our terms. Sado-sadomasochistic sex teaching takes time to achieve the trainees potential, and we have as much time as it takes.
Now that her body is completely weary we tie her down so that Derrick can use her crevices the way that they should be used. She is pounded hard and swift and numerous orgasms are torn from her tired slit.
