Mommy can't come suddenly, so Mio-chan takes care of her instead! When she sees my penis while I'm changing, it swells up, and she licks it with her mouth worriedly, saying "I might be sick...", and the tingling doesn't stop, so white pee comes out! But the swelling doesn't go down, so I hold it between my breasts, rub it with my hands while licking my breasts, and put it in my crotch where the sticky medicine comes out, and I pee it out many times! It's warm and comfortable inside my sister, and I can't stop peeing!
