Horny and insatiable, I find myself alone in the bathroom, my libido raging. I decide to take matters into my own hands, literally. I prop my leg up on the sink, exposing my wet, throbbing pussy to the cool air. As I start to rub my clit, I hear footsteps approaching. My heart races as I realize it's my stepson. He bursts in, catching me in the act, his eyes widening at the sight of my naked, vulnerable body. I feel a surge of embarrassment, but also a spark of something else - desire. I can't help but notice the growing bulge in his pants. He hesitates, then turns to leave, but I stop him. "Don't go," I pant, my voice laced with lust. He turns back, his eyes filled with a mix of shock and desire. I beckon him closer, my fingers still playing with my clit. "Fuck me," I whisper, my voice barely audible. He hesitates for a moment, then steps forward, his hands reaching for my body.
