Still can't get up?! My sleeping sister's private parts are already soaking wet! Sleeping with my sister, who has terrible sleeping habits, on our long-awaited hot spring trip, her underwear is completely visible!! AP-128

During a long-awaited hot spring trip, I slept with my older sister. She was sleeping in such a bad position that her underwear and breasts were completely visible! Unable to bear it any longer, I rubbed my penis against her private parts through a piece of cloth, and her private parts were already soaking wet! Then my penis slid down and entered her vagina, and before I ejaculated, I couldn't stop thrusting back and forth!
