Young and seductive stepsister can't resist the size of my penis

My stepsister is a total babe. She's got this irresistible charm that's just impossible to resist. Plus, she's got this thing for my big cock. I mean, who wouldn't? It's fucking massive. Every time she's over, she's always teasing me about it. She's always asking to see it, and of course, I can't say no. So, one day, we're hanging out and she's being her usual seductive self. She's got this look in her eyes that's just begging for it. I take off my pants and she's all over it. She's sucking it like her life depends on it. After a good deepthroat, she's ready to get fucked. She's a total slut and takes it like a champ. I'm pounding her so hard, she's screaming in pleasure. After a good pounding, I fill her up with my hot load. What a lucky guy I am.
