My Stepsister gives me Oral Sex and I Cum Throbbing in her Mouth!

Imagine a steamy summer day, the sun is beating down on the roof, and the house is quiet. You're lying on your bed, your thoughts racing, when suddenly, your step-sister walks in. She's wearing a tiny, barely-there outfit that hints at the curves hidden beneath. You can't help but notice the way her big, brown eyes sparkle with mischief and her full, pouty lips curl into a teasing smile. She knows what she's doing, and she's loving every second of it.

She struts over to you, her hips swaying gently, and sits down on the edge of your bed. "You know what I've been thinking about?" she asks, her voice sultry and low. Before you can answer, she leans in and whispers, "How big your dick is and how much fun it would be to suck it." Your heart races as you feel your cock starting to stir.

She reaches down and unzips your jeans, pulling out your throbbing cock. Her eyes widen in appreciation as she takes it all in. It's long and thick, and she can't wait to wrap her lips around it. She leans in, her tongue flicking out to lick the tip, and you let out a low groan. She smiles, knowing she's driving you wild.

She takes you in her mouth, her lips stretching around the massive size. She starts to bob her head, taking more of you with each motion. You can feel her throat working, and it's almost too much to bear. She's like a pro, her head moving up and down, her tongue swirling around your shaft.

You can't help but let out a low moan as she takes you even deeper. She's gagging slightly, but she's not stopping. She wants all of you. You can feel the pleasure building, your cock throbbing in her mouth. She's so good at this, her head moving faster and faster.

Just as you're about to blow, she pulls back, your cock sliding out of her mouth with a wet pop. She looks up at you, her eyes filled with lust. "Cum in my mouth," she whispers, and you don't need to be told twice. You let out a low groan as your hot cum shoots out, filling her mouth. She swallows every last drop, her throat working to take it all in.

You're both breathing heavy, your bodies glistening with sweat. She leans in and kisses you, her tongue swirling around, tasting your cum. It's a moment of pure bliss, a secret you'll both keep.
