Lessons for the Crude Brother

That thorn in my side, my elder brother Yunjun. He's already such a nuisance, and now he's summoning a male courtesan behind my back! Yunhyung simply couldn't let his elder brother Yunjun get away with this. He resolved to give him such a thorough thrashing he wouldn't know which way was up. "I never imagined my elder brother would be a sodomite." "Brother, this is... Ugh!" "Does that woman know too? That you, a man of honour, call in some bloke for such debauchery?" Yun-jun’s flushed, dishevelled form was revealed, and Yun-hyeong, excited by his elder brother’s unusual appearance, licked his dry lips with his tongue. “Whether you’re sodomising or secretly selling your backside, I don’t care. But.” “…….” “You must sell it to me too.” --- **Original Webtoon:** [Ridibooks](https://ridibooks.com/books/1286012237), [MrBlue](https://www.mrblue.com/webtoon/wt_000076806)
