A good conclusion, but a faulty anaylsis; Inoda genuinely thought he was aphrodisiac drugging Asuna so she wouldn't/couldn't resist. It highlights his own insecurity, even at this point. He lacked the courage to just go for it himself, even after basically pushing himself on her in the shower where she rubbed him. He only had the balls to do it because he thought he'd worked around her resistance with drugs. Fujino's still skipped over their whole date day, which was an intense point at the end of EP1 that's never been explored. I was hoping we'd get to see him softening her up at a few date locations throughout the day first, seeing as he already had her stroking him in the shower by that point.
