Taboo Temptation: Sister's Ass Initiation

Unbeknownst to their strict parents, these siblings have been sneaking into each other's rooms at night, exploring their bodies and desires. Tonight, they've decided to push their boundaries further. The brother, hard as a rock, watches his sister strip, her ass cheeks jiggling as she bends over to remove her panties. He can't resist anymore; he grabs her hips, his cock sliding between her ass cheeks. She pushes back, encouraging him. He spits on her hole, rubbing it in before pushing his tip in. She cries out, but he holds her steady, inching in deeper, filling her ass as she claws at the sheets, whimpering with a mix of pain and pleasure.
