腕が疲れているのでは？

Blue-haired college student takes it from the disciplinarian, first bare handed, but then he whacks her really hard with the strap, moving down to the thighs. He loves to feel her ass and smack it with his hands while her exposed pussy winks at him. Blue-haired angel is sent out to bring her schoolmate who also takes the strap. This fellow gives no quarter. He lays into both these deserving students. He loves his job, obviously, and who wouldnt. He wants them to beg him to stop and how can they not? Looks like her legs are tattooed to simulate stockings. Nice touch.
