NHDTB-347 "Let's go in together for the first time in a while," my sister invited me to join her in a lubricant bath. The slippery sensation drove me mad with pleasure, leading to a wet and wild sex session.

Due to an unexpected turn of events, a younger brother ends up taking a bath with his sister. What's more, the bathtub is filled with slippery lotion! The sister, excited by her first experience in a lotion bath, goes on a rampage. She enjoys playing pranks, smearing each other, and getting close... the situation escalates intensely!! Before she knows it, the sister is having an orgasm so intense she wets herself! Ultimately, she crosses the forbidden line out of desire for her brother's dick!
