Step Sister

His new stepsister, Emily, is nineteen years old, heavily muscled and six foot eight. She immediately starts to bully him and tells him his car is in her spot. She rolls the car onto its roof. Then she kicks him in the belly and delivered a painful and humiliating spanking. His sister Teddy tries to help by rubbing cream onto his sore arse, but she uses something that Emily gave her, which makes things much worse. Emily holds him upside down betwen her thighs, while Teddy rubs on more of the painful cream. Several days later, Emily apologises for her behaviour, and explained that it was a testosterone thing, and she needed help to deal with it - the help being, of course, sex. But sex with a powerful muscle girl is great at first, but as the hours go by it is more painful, humiliating and embarrassing. Then Emily started to have a sexual relationship with his sister Teddy! And then the new mom used dad as a test subject for her business. Her business was items for discipline.
