After years apart, siblings reconnect, their tension palpable. As they reminisce, the air grows thick with unspoken longing. The brother can't help but notice his sister's curves, and she catches him staring at her exposed thigh. Their conversation turns heated, and before they know it, clothes start to come off. She takes his throbbing cock in her hand, guiding it to her wet slit, riding him reverse cowgirl as he grips her hips. They fuck passionately, their taboo lust consuming them, until they both cum violently, leaving them breathless and guilty.
