My step sister discovers my massive member and craves penetration

When my step sister stumbles upon a risqué photo on my phone, she's left with an insatiable curiosity. Her eyes widen as she takes in the sight of a massive cock, and she can't help but be captivated by the thought of what it would feel like. She's always been a bit of a prude, but the allure of such a huge member is too much to resist. She's eager to explore this newfound desire, and I'm more than willing to oblige. I start by teasing her nipples, sending shivers down her spine. Then, I slide a finger into her tight asshole, stretching her limits. Finally, the moment she's been waiting for arrives. I unleash my monster cock, and she eagerly takes it in her mouth. The sight of her gagging on my thick shaft is enough to send me over the edge. I pull out just in time, covering her face in a hot load. The taste of my cum only fuels her desire further, and I can't help but wonder what else she'll discover about herself.
