The long-awaited [Ideal Sister] series begins! An ideal sister is a sister who is the embodiment of what every man fantasizes about at least once: "It would be nice to have an older sister like this." Beautiful big breasts + slim waist + strangely familiar manner of communication. She will listen to your sexual desires that are difficult to express in an easy-to-answer manner! This time, the instructor is a slippery, wet, see-through, beautiful big-breasted sister! She always wears tight clothing and unconsciously exudes pheromones, seducing younger brothers, virgins, older men, and everyone else! "Hmm? Boobs? That's good, want to touch them?"
