When my family came to the hot springs, my younger sister was so excited! - My sister was tired, so she tried to call for a massage, but it was fully booked. - So she had no choice but to ask me for a massage. - However, as I continued to massage her, her yukata came undone, and I could see glimpses of her breasts, thighs, and panties, and I got an erection! - When I touch my sister's sensitive parts, she reacts so much that she gets so excited that her panties get stained! - "Hey...I want you to touch me more," she said.
