DRS-030 - Help Me Train for the Marathon? My Sister's Humiliating Workout Session 6

This is a very well-balanced, high-quality entry in the series. The actress is flawless as the 'big sister' type—her face, body, and way of speaking are all on point. The fact that her airheadedness—accepting any sexual harassment as 'just training'—comes across as charming rather than stupid is a huge plus. I wish they’d cast a younger-looking actor, but he’s not bad enough to ruin the vibe, so he gets a passing grade. As is true for the whole series, the younger brother has zero presence. If they’re against incest, fine, but if his hobby is peeping on his sister in the bath and he’s even dreaming about getting oral sex from her, shouldn't there be a bit more action?
