Doctoral candidate Codi Vore is a girl on a mission in the chemistry lab. Her personal project is to create the ultimate pheromone. If she succeeds, her supervisor will learn that she’s as good a scientist as he is, if not better. Codi has been working on her formula. Now it’s time to test it.

Codi’s test subject is herself. It’s a risky move but she’s willing to gamble. She pours liquid into a glass and drinks it. At first, it looks like her experiment has gone wrong and she’s about to turn into Ms. Hyde, but then her expression changes to a look of pure ecstasy and pleasure. Her formula is not only a pheromone sending out sexual signals; it’s an aphrodisiac and it’s turning her on so much, she pulls off her clothes to squeeze and rub her large, heavy tits, so soft to the touch. Her discovery works all too well.

Totally naked and leaving her high-heeled shoes on, beautiful Codi sinks into an ottoman, her legs in the air, and double-fingers her fur-lined pussy hard and fast, rubbing her clit faster and faster. She cums with a scream, and just when she thinks the effect of her formula has subsided, Codi feels it taking over again and gets on her knees to pleasure herself once more. Codi’s big-boob theory is a success.
