[Reducing Mosaic]JUQ-169 "Really, it's only the tip, just 3cm..." A week of teasing and friends-with-benefits with a childhood friend you haven't seen in a while—starting with some mischief. Hibiki Otsuki

After several years of marriage, he got used to quarreling with his wife, and three weeks have passed since she returned to her parents' house. When she was alone complaining about her, she got a call from her childhood friend Hibiki. She decided to meet him for the first time in a while, and invited her to her home. When I was immersed in her memories, I pushed down Hibiki because of her frustration. Kissing is no good... but what if it's something else? When asked, she neither denied nor affirmed with a flushed face. And if it's only 3 cm, it's not cheating, and a distorted unfaithful relationship begins.
