There is a trend of "One-katsu" not "Papa-katsu". I don't know if it's dangerous for you to spend time with a sister you don't know... but... Everyone's doing it. It's okay, right? The protagonist makes his debut in the one-katsu with such a light heart. The sister is a good cook, has big tits and is kind and I thought it would end up being a happy day... You owe me for today. She is shown her fat tits and is asked to milk them. Squeezing, drinking, getting sucked off breastfeeding and all that everyday wet life eh!
