[Reducing Mosaic]JUY-644 Stormy Night: A Night Alone with My Desired Sister-in-Law Rina Shiraishi

It's been a year since I started living with my brother and his parents at home. My sister-in-law Rena, who secretly has feelings for me, is traveling abroad. I'm planning to come back today, but the typhoon is hitting me right now... Alone in an empty house, lost in thought like that, the chime of my home rang. Hurriedly heading to the entrance, Torena-san was standing soaked from the rain... I couldn't take my eyes off ≪Glossy wet hair... Rain dripping from my jeans... Wet and see-through underwear≫.
