CAWD-850 IQ140, 23-year-old science sister. Secret medicine completed that could never be included in a master's thesis. The result of becoming the experiment subject herself is ◎ brilliant, an impressive climax. Rui Suzune

IQ140, a 23-year-old science sister. This time, we're visiting the research lab at a certain famous science university where she is currently enrolled. It seems her curiosity about sex is too strong, and she started making aphrodisiacs herself… Apparently, she plans to use it in her next work, and on top of that, she's challenging herself with abstinence until the shoot. On the day of the shoot, the moment she had sex for the first time, she came so hard she was like seeing an egg. The more aphrodisiac she applied, the more convulsions she had, and her squirting orgasms were massive. This is a forbidden drug. Of course, she moaned in ecstasy. She couldn't even hold back from urinating, and her pussy became unable to recover, falling into a state of blissful orgasm. But despite conducting such an extreme sex experiment, she didn't regret it but discovered new things, accelerating her curiosity about sex. It seems the aphrodisiac was a perfect blend worthy of a Nobel Prize in Chemistry.
