A book about aphrodisiacs found in a used bookstore. The man who mixed the aphrodisiac according to the book wanted to try it out on the body of a girl who was always engrossed in reading in the park... When the girl was given the aphrodisiac, her reasoning was lost, her love juices dripped, and she begged for the man's cock while drooling! The beautiful literary girl who was so quiet ended up straddling the man in a state of tripping, and repeatedly engaged in drug-induced sex!
