Blushing sisters, curious and horny, find themselves alone with their stepbrother. They giggle and tease, calling each other 'cute' as they dare each other to touch his growing erection. He's hesitant but excited, his cock twitching as they take turns licking and sucking it. They're shocked by their own boldness, yet can't stop. Soon, they're naked, their petite bodies pressed against him, their tight pussies dripping. They take turns riding his thick cock, moaning softly, their eyes locked, experiencing their first shared orgasm.
