HUNTB-204 — I Was So Excited That I Got A Stain On My Pants! I Ended Up Giving My Sister A Massage At A Hot Spring Inn... When My Family Went To A Hot Spring, My Sister Was So Excited! I Got Tired, So My Sister...

When we went to a hot spring with my family, my sister was so excited! She was tired, so she tried to call a masseuse, but all the appointments were booked. So she had no choice but to ask me to give her a massage. However, as I massaged her, her yukata came undone, and I could see her breasts, thighs, panties, and other parts of her body, and I got so excited! I took the opportunity to touch her sensitive parts, and this time she reacted so much that she got so excited that she stained her panties! She said, "Hey... I want you to touch me more."
