In the sultry heat of a summer afternoon, a brother and sister find themselves alone in the house, their parents away. Boredom and restless hormones lead them to explore each other's bodies, starting innocently with shared masturbation. Michelle, the older sister, fingers her wet pussy, her moans growing louder as her brother watches, stroking his growing erection. Their playful touches escalate, and soon, Michelle is begging her brother to fill her with his thick cock. They're interrupted just as things heat up, leaving them both breathless and yearning for more.
