This anime is pretty old but it is still pretty popular. I'm really surprised that nobody ever bought the rights for this anime and made a full fledged hentai out if it.
Same thing with "Twin Angels". All everyone ever wanted was to see AI and Mai get fucked, and when it finally happened after 6+ episodes of teasing, it was sort of "conveniently censored" by not really showing the actual penetration for long... there was no anal, no fellatio and the vaginal was shown all for 1 second. No, I'm serious ONE second was shown... then some zoom on on the face and then it was over after 20 seconds or so. I mean for sure Twin Angels always tried to take itself seriously and have some actually interesting story -- but why did the actual ero scenes have to suffer?
Anyway, Yohko really needed some good dicking and that guy that was shown to be in love with her in the first episode should have been allowed to come back and fuck her in a later episode. I mean, at the very least a blowjob should have been okay since that wouldn't have broken her maidenhood... nor would anal.
