付き合ってから2年の年月が経過。喧嘩することもなく順調に愛し合っていた二人。あんなに大好きだったゆらとのセックスもここ最近はマンネリ気味。以前から寝取られ願望があり先輩達に自分の彼女を寝取ってもらうようお願いすることに。最初は戸惑っていた彼女も徐々にその快感に溺れていく。Two years have passed since they started dating. The two of them had been loving each other without any quarrels. However, the sex with Yura, which she loved so much, has been in a rut lately. She has always had a desire to be cuckolded, and decides to ask her older classmates to cuckold her. At first she is a bit bewildered and out of her depth, but gradually she drowns in her own pleasure.
