Hmm, not sure about the timing of this. Robbie looks normal but Wendy and Tambry look like their in college or already reaching 'MILF' status. I know body-types and size discrepancies are irrelevant when it comes to hentai, but I'm not sure why I thought about this nitpick.
Something's funky with the dialogue. Robbie and Tambry read approximately like human beings, but Wendy reads like, I dunno, not someone in the middle of getting screwed? Like some kind of robot that has to explain things nobody actually asked about.
