Applying Sunscreen before the Beach Turned out to be Sex but the Step Sister didn't Mind

Imagine you're at the beach, the sun is blazing hot, and you're all set to enjoy the day. Suddenly, your step-sister, the sexy blonde bombshell, spots you and says, "Hey, let me help you with some sunscreen!" You're not one to refuse a helping hand, so you lie back on your towel. But little did you know, this wasn't just any step-sister, this was a step-sister with a hot fantasy. As she starts rubbing the lotion into your back, you can feel her hands getting a bit more intimate than necessary. She's grinding against you, her breathing getting heavier, and you realize that this sunscreen application has turned into something much, much hotter. You're not sure what to do, but she's not giving you a chance to back out. She turns you around, and you're face-to-face with her tight, small body. She straddles you, grinding against your crotch, and you can feel her arousal through her bathing suit. You're both panting, and it's clear that neither of you can stop now. She unbuttons your shorts, and you're ready for anything she throws at you. She takes you in her mouth, her petite body moving up and down your length. You can feel yourself getting closer to the edge, and she knows it. She looks up at you with a naughty grin and takes you even deeper, her tiny hand gripping the base. You can't hold back any longer, and you explode in her mouth, the warm sensation of your release filling her throat. She swallows every last drop, her eyes never leaving yours. You're both panting, and it's clear that this step-sister isn't done with you yet. But for now, you're both satisfied, and you know that this is just the beginning of many more hot, sunscreen-related fantasies.
