[Kaiten Sommelier (13.)] 27Kaiten BACK SHOT! [Kalevala]

Schoolgirls Miyuki and Ibuki run a brisk lunch-break business servicing their classmates, with Ibuki's plump, soft chest draining boys dry in sloppy paizuri while Miyuki offers her ass to regulars who stretch her wide and leave her gulping down load after load. Between group sessions and backdoor pounding, the pair keeps a prostitution diary recording every satisfied customer. When exam week arrives, studious Miyuki tries to enforce a no-escort rule, but Ibuki—aching and worked up from reading the diary—is determined to get pounded again.
