Deep Throat Practice Turns into Filthy Family Secret

She got on her knees and took every inch down her throat just like he taught her loving how he groaned each time she gagged. Her eyes watered but she kept going wanting to prove she could handle him better than anyone else. He grabbed her hair and pushed deeper until he exploded filling her mouth with his warm cum. She swallowed it all with a naughty smile knowing they would do it again the second they were alone.
