Anna's Wet Dress Rubbing: Public Masturbation Frenzy

I'm growing up, and I need some privacy! I wanted to touch myself all the time, but my stepbrother was always around, so I discovered how wonderful the public could be. I'd slip into a tight dress, feeling the fabric hug my curves, and head out to the park. The breeze would tease my nipples, making them hard, and I'd feel a throbbing between my legs. I'd find a secluded bench, lift my dress, and slide my fingers into my wet pussy. The sensation was electric, and I'd moan softly, hoping no one would hear. But sometimes, someone did. Like Austin, my stepbrother, who'd watch from a distance, his cock hard in his jeans. He'd come closer, his eyes locked on my tits, and I'd invite him to join. We'd fuck right there, my dress hiked up, his big cock sliding in and out of my pussy. The risk of getting caught made it even hotter. Sometimes, my stepmom would walk by, and we'd have to stop, but the anticipation of continuing later was almost as good as the act itself. I'd come home, my body still tingling, and think about the next time I'd get to touch myself in public.
