The protagonist hated his elite, successful elder brother, and yearned for Yuuko, his brother's wife. One day he saw her expressing her milk and lost all control! Dining room, bathtub, marital bed, he seized on her womanly body and suckled her creamy nectar, living a cuckolding slob's dream! * Gross fat stepbrother x married sister-in-law! The sleazy manchild laps, tweaks and f*cks her milky breasts! His big c*ck makes her shriek with pleasure, seduced, mating with immoral satisfaction! The white ambrosia meant for her child is slurped up greedily by a giant infantile pervert! * Post-birth milk gush extreme! Mommy's copious lactation is monopolized! The fat slob drinks and slathers her milk like a lotion. Her body is a white slicked playland! Whether it's expressed by her husband or by herself, his tongue will taste it all! * Stolen from elder brother! The protagonist makes a fool of his brother's trust by fooling around with his wife under the very table they eat, the doorway to their home, the instant he's asleep... his mouth gloms onto her overripe tits, because her flesh is his! Soiling even her wedding dress and the photos of marriage ceremony, what a disgrace!
