In the hushed silence of their shared bedroom, the siblings give in to their taboo longing. She kneels before him, her eyes locked on his, as she takes his rigid cock into her mouth. Her tongue swirls around the sensitive tip, tasting the pre-cum that beads there. She sucks him greedily, her head moving in a hypnotic rhythm, as he fists her hair, holding her close. Their bodies are a tangle of limbs, her breath ragged as she takes him deeper, feeling his cock pulse with impending release.
