When I returned home for the first time in several years, my sister was still a lethargic NEET and a shut-in. She spends the day dressed sloppily and behaving in a disrespectful manner that is harsh on her mother. She's already given up on her life. But I was the one who put my hands on her older sister the most... I got excited by the big boobs that were visible through the Darudal T-shirt, and when I inserted my dick, it was the first time in many years that my girlfriend's older sister was mourning.
