My girlfriend Rie and I go to a prestigious school. Rie is a member of the volleyball club, but because the school doesn't place much emphasis on club activities, no new members have been joining, and now Rie is the only member. The advisor apparently provides one-on-one instruction, but I always feel like he's ogling the female students with lustful eyes, which worries me. Still, Rie trusts the advisor, and I don't think it's my place to say anything, so I don't say anything forcefully. One day, when Rie feels something wrong with her leg, she consults the advisor, who offers to give her a massage. Rie accepts without question when the advisor offers to apply a high-quality, highly effective ointment. The drug, which turns out to be a powerful aphrodisiac, is carefully rubbed into Rie's sensitive areas, and her body goes wild with the drug-induced massage...
