Aubrey Sinclair and Kimmy Granger have always thought they were sisters but today, a book changed everything. Kimmy accidentally comes across an old book that their parents have been keeping hidden away, but when she opens it she discovers the plot twist that proves her crush on her little sister hasn’t been as sickeningly taboo as she thought.
When Kimmy opens the book and discovers that Aubrey is in fact not her real sister, she shivers in sexual excitement. She tries to prove the facts at least before she seduces her little (not so) sister Aubrey. Dear Aubrey Sinclair is innocent to all of Kimmy’s plans, and tries to remain firm on her feelings about their familiar situation, but Kimmy is so persuasive, and so sexy, that Aubrey can’t help getting into it with her.
Kimmy asks first, but soon licks Aubrey’s sweet little clit, writhing like a horny teen with a sexual hunger like no one ever before her. Aubrey’s cute little screams further induce Kimmy’s orgasmic writhing and after plenty of practice, Aubrey and Kimmy both cum, sharing an experience neither of them expected. But, thanks to a book, all that has changed.
