エッチなパンツを穿いて登校したけど我慢出来ずオナニーする少年 (Fantia)

興味本位で透けたエロいデザインのパンツを買って、制服の下に穿いて登校した少年。我慢出来ず学校のトイレでオナニーしてます🥰 --- R18プランにご加入頂いている方は穿いたまま射精、パンツ脱ぎ射精の差分をご覧頂けます。 投稿が31日と遅くなりすみません。別のを描いていたのですが、仕上げ直前まで進めてもどうしても気に入らず、それをボツにして、また新しく描いていたので時間がかかってしまいました･･･。ボツにしたイラストもおまけに載せておきますね。 2020年も皆様のご支援に大変助けられました。本当に感謝しています。2021年がいい年になりますように。 ==== [EN] "A boy wears naughty pants to school, but can't resist masturbating" A boy buys a pair of transparent pants and wears them to school under his uniform. He can't stand it and masturbates in the school bathroom🥰 --- If you have subscribed to the R18 plan, you can see the difference between ejaculation with pants on and ejaculation with pants off. I'm sorry for the late posting on the 31st. I had been working on another one, but I couldn't get it right until I finished it, so I rejected it and started over again. It took me a long time because I had to reject it and draw a new one... I'll post the rejected illustration as a bonus. I would like to thank everyone for their support in 2020. I hope that 2021 will be a good year for you.
