Even a current female college student like nee-chan gets wet while modeling nude. She feels it... down there, all slippery and squishy under the serious gaze of male art students sketching her...? During a sketch session with a male model, their bodies touch, she gets aroused, and they end up having raw sex!? Even during sex, she's sketched non-stop, driving the sensitive nee-chan JD to be filled with a massive internal ejaculation!
