Under the kotatsu, an uncle's lust for his niece grows unbearable. He can't help but stroke her smooth, warm skin, her soft moans encouraging him further. His fingers delve into her panties, finding her slit slick with desire. He teases her clit, his tongue flicking against her nipple, causing her to arch into him. She whimpers, her body tensing as he brings her to the brink, before backing off, leaving her gasping and begging for release.
