And a few days later, when Natsuko returned from the trip, she was surprisingly tanned! Natsuko, who can't help but feel like she's on vacation, changes into a bikini in front of her son. Her brown skin and plump body become so lewd and excited, she runs away to the bathroom. However, after pursuing her son, her mother shows off something even more bold!
