What if your cute little sister was Tsubomi-chan, smiling broadly and saying, "I love you, big brother!"? A monumental work that will make that dream come true is being released by the new label, "Moekko Product"! She receives a large amount of thick semen in her mouth and transforms into whatever costume her big brother likes. Her devoted physical service is proof of her love! *There are no performers under the age of 18 in this work.
