step-Mom Magicked into Ahegao Slut

You're a warlock. You've always known that, what with your step-mom and step-dad being magick. It's not like some stories in a book, though. It's a total secret, even from your friends. You don't learn in class or at some special school. Your step-mom teaches you. Lately, you've been working on control, object manipulation...and that led you down some fun paths on the internet. You decided...to try it out. The hardest conjuration you'll ever do: controlling your step-mom into a total ahegao anal slut. At first, you think you'll just have her use a toy, but after beating off over it, you decide you need something more. Your cock! No...not just that...your cock, enchanted. Your cock, but MONSTER HUGE. So big you spend the whole time with you giggling, drooling step-mother just trying to fit the head in! Once the potion wears off, and you've got her covered in cum, though? Well, you don't need magick anymore. She's still begging, still trying to get your mammoth cock inside her ass. Next time, you just know it. Next time you'll get buried deep into her hole...
