Two curious siblings, hidden away in their shared bedroom, can't resist exploring each other's bodies. The younger sister, her eyes wide with curiosity, tentatively takes her brother's hardening cock in her small hand, feeling its weight and warmth. He responds by gently parting her thighs, revealing her damp panties. They exchange nervous glances, hearts pounding, as they tentatively begin to pleasure each other, their inexperience making their touches clumsy yet thrilling.
