Title and description amended to comply with the new t&cs- Step-Mommy stumbles in from another night out, you're waiting up for her this time, and you're not going to accept her lies. She tells you it's just another night with her girlfriends, she lost her phone and didn't realise the time. But you stole her phone and went through all the cheating slutty messages, photos of her sucking another man's cock and videos of her bouncing on his dick. She's cheating on step-dad, and you're going to make her pay. You give step-mommy a collar, she is to wear this at all times, and to be your obedient sex slave, your own fuck toy. You have free use of step-mommys holes, and can fuck her whenever you want. Step-Mommy is horrified at first, but what choice does she have. Strapping on her collar, she gets ready to have her tight slave pussy used. Her life is going to change forever, becoming obsessed and worshipping her Master's cock.
