Aiden Valentine, the quintessential stepson, finds himself alone with his stepsister, a beautiful blonde with a body that's far from little. He can't help but fantasize about her, his cock growing hard in his hand as he strokes himself. Just as he's about to cum, she walks in, her eyes widening at the sight of his cock. Instead of leaving, she stays, her curiosity piqued. Aiden, seeing an opportunity, asks her to help, and she tentatively reaches out, her small hand wrapping around his throbbing cock. He groans, feeling the pressure build, and before she can pull away, he cums, his load covering her hand and his abs, leaving them both breathless and wanting more.
