A certain student was next to the Aika Yumeno couple. He was single and sexually craving, so he often went to the balcony to see the underwear of Aika's neighbor. One day a pair of pants flying to his house, so he brought Aika and from that moment he was taken into her sights. When he rises, he climbed to the balcony of Aika's house and then smelled the scent of the panties she dried, which was caught by Aika and she invited him to the house to resolve. And she gave him a big gift, they made love to each other very strongly. From that day onwards, every time Aika dried underwear was also signaling for her husband's absence, the neighbor just ... climbed over and ... hit.
