You Became a Public Good, Sir

One day, the Crown Prince of the Empire suddenly fell ill. Despite the efforts of all the Empire’s physicians, the Crown Prince’s condition only worsened. The Emperor fell into deep despair. At that moment, an oracle was delivered.
[The Crown Prince will be cured if he drinks the milk of Sir Kedrick Lachenov.]
Kedrick Lachenov. Known as the guardian of the royal family, the Commander Knight of Lexion. Without hesitation, he accepted the oracle.
“I am Kedrick Luthens of the Lachenov family and the Commander of the Knights of Lexion. As long as my loyalty to the royal family remains unchanged, I will gladly offer my life if asked.”
Kedrick was subsequently imprisoned in the temple’s underground and subjected to various methods of inducing lactation. Until milk began to flow from his chest.
“…When will I be able to go back?”
“Why are you asking me that, Kedrick? You should be asking your own chest.”
Lewis l**ked his thin lower lip, anticipating Kedrick’s face, twisted in shame and near tears.
“Thinking about you begging and crying to have your chest touched is so exciting… it’s driving me crazy.”
The golden eyes, once fiercely shining like a wild beast, became moist and distorted. Each time Kedrick gasped for air, his large chest swayed.
“Isn’t this all for His Highness the Crown Prince?”
