Lala's mom is a world-famous ballerina. She will be away from home for more than a month for her London performance. She is also a world-famous SM dominatrix, and has arranged for a cute pet man to be there for Lala, who will be home alone. "Mommy is so kind! I love her!" But Mama isn't just kind. In her letter, Mama wrote, "Lala, you'll need to get over your peeing habits soon so you can make your social debut as a fine lady. I've prepared a pet for you this time, a diaper-loving old man, so give him lots of Ke'ai and help him get over your peeing habits." And those ruthlessly harsh words... Lara-chan is innocent but curious about anything naughty, and she loves diapers and has a pet old man. The two of them try to hold in their pee in diapers, make the old man use a washlet on their crotch that's soiled from peeing, lick his hard cock and make him squirt white milk, and try to hold in their pee while using a vibrator, imitating an SM video... We took a peek into the embarrassing and fancy life of a child staying at home while potty training.
