With a hushed whisper, Michelle invites Mary into their shared closet, a sanctuary from their father's strict rules. They huddle together, their bodies warm and pressed close. Michelle's hand finds Mary's, guiding it to their brother's cock, already hard and straining against his pajama pants. They help each other free it, their breaths hitching as they take in its size. Mary tentatively licks the tip, tasting the pre-cum, while Michelle takes the shaft deep into her mouth. They learn together, their tongues exploring, their hands caressing, their bodies yearning for more. Their brother, too lost in pleasure, doesn't notice their father's shadow looming outside the closet door.
