Revenge

Kevin was 18 years old and had graduated as the valedictorian of his high school. He was at home with his two older, and very annoying stepsisters Kennedy and Brooklyn when his dad and stepmom went on a week's vacation.

Both Kennedy and Brooklyn had gone off to college and flunked out due to too much partying and not enough studying. Kennedy was the blonde, 21 years old and working as a waitress, and Brooklyn was 20 and working as receptionist at a car dealership. They were both self-absorbed and dreamed of being rich as social media influencers, but neither could do it.

Kevin had developed a mind control drug in secret with his basement chemist set with items he pilfered from his part time job as an intern at a pharmaceutical company. He had drugged his stepsisters and when they were a trance, had each of them believe she was very horny and needed Kevin's cock more than anything and nothing made them happier than being fuck bunnies.

It worked like a charm.
