Sapna's brother-in-law, driven by lust, seizes the opportunity when everyone's away. He watches Sapna sleeping, her curves inviting, her breaths soft. His Hindi whispers narrate his growing desire as he gently removes her blanket, revealing her lush body. He can't resist, slowly moving on top, his hard cock pressing against her ass. She stirs slightly, but he's careful, his hands exploring her, fingers finding her wetness. He slides in, her warmth enveloping him. She moans softly in her sleep, pushing back, encouraging him. He fucks her slow and deep, his voice husky as he describes their taboo act. His pace quickens, his breaths ragged, until he can't hold back, filling her with his hot cum.
