Sam brings home his new girlfriend, Mia, to meet me. Things seem to be going well. She has an amazing GPA, she volunteers at a food bank, and she is very dedicated to her family. So I ask her to strip. At first, she’s incensed, but with some encouragement from Sam, she goes along with it. I look at her whole body and even examine her pussy. However, something just feels…off. Eventually I get it out of them that they’ve been fooling around behind my back, without my permission! Well, that’s a deal breaker for me. I inform Mia that, as his step-mom, I own Sam’s cock, and anyone else who wants to touch it or even look at it needs my permission. I prove it to her by giving him a hard, fast handjob right there in front of her, as she squeaks in disbelief. My step-son, my cock, my rules!
