Shipon, the doting husband, leaves for work, leaving his beautiful, busty step-sister Riya home alone. Bored and horny, Riya starts to touch herself, her fingers tracing her curves as she imagines her brother's touch. She's interrupted by a text message - it's Shipon, asking her to pick up some groceries. Frustrated, she heads out, only to find her brother waiting for her at the store. They bump into each other in the aisles, the tension palpable. Riya's nipples harden as she feels her brother's gaze on her body. They return home together, the sexual tension building with each step.
