After-school delight: Step-sis takes every inch of my monster cock

I've been getting my fill of my step-sis, and I'm not talking about just her tight ass. I mean, she's been giving me the best BJ ever, and I can't get enough of it. She's been begging me to teach her how to suck my monster cock, and I've been more than willing to oblige. I've been taking her to my dorm room after school, where we can have some alone time and practice our skills. She's been working hard to please me, licking and sucking every inch of my huge cock, and I can't help but moan with pleasure. I've been teaching her all the tricks, from deepthroating to muff diving, and she's been taking it all in stride. But it's not just about the cock, it's about the whole experience. We've been exploring each other's bodies, giving each other ass and making out in the classroom. This is the life, and I don't plan on stopping anytime soon.
