(This is a custom clip and I can make one for you too! Just send me a DM!!) This would be the premise: a young man's step-mother was a party girl turned addict and abandoned him at a young age. Years later, she comes knocking at his door one day and needs money and a place to stay, having burned all of her bridges. She tries to use the familial obligation card to no avail. Her step-son will only let her stay and fund her party girl lifestyle if she becomes his fuck slave. She resists at first, but ultimately relents, finding that she loves riding her step-son's cock. BTW, I love hearing the dirtiest taboo word if you're amenable to that.
