IQ 140, 23 years old, a scientific older sister. A secret drug that could never be presented in a research paper has been completed. The result of becoming the test subject herself is... ◎It's amazing, a breathtaking climax. Ryoune Rui CAWD-850

A 23-year-old science enthusiast with an IQ of 140. This time, I visited the research lab at her current university, a prestigious science-focused university. It seems her sexual curiosity is too strong, so she started making her own aphrodisiac… She said she would use it in her next project and even challenged herself to abstain from sex before filming. On the day of filming, during her first time having sex, her orgasm was so intense it shocked even those I'd seen; she practically collapsed like an egg during her orgasm. The more aphrodisiac she applied, the more spasms she experienced, and the more abundant her orgasmic ejaculation. This is a forbidden drug. Ah-hei's orgasm was inevitable. Unable to stop the orgasm, her vagina unable to become erect again, she was lost in a state of ecstatic climax. Just conducting such an extreme orgasmic sex experiment, yet she gained a deeper understanding of the new discovery than regret, and her desire to explore sex accelerated. It seems the aphrodisiac is a perfect formula worthy of a Nobel Prize in Chemistry.
