Tonari no Onee-san wa Osewazuki
隣のお姉さんはお世話好き
The protagonist has always adored the older sister who lives next door. She used to play with him when they were younger, and now that they are adults, she continues to fuss over him with affectionate care. One day, as she leans close to him, he becomes intensely aware of her mature body—soft curves and a womanly scent that stir something deep inside him. His heart races, and he finds himself unable to look away from her figure.
Overwhelmed by a sudden surge of desire, he blurts out a request for her to jerk him off. To his surprise, she does not refuse. Instead, she responds with a teasing smile, and their interaction quickly escalates into a passionate sexual encounter. What begins as an impulsive plea turns into a series of intimate moments between them, blurring the lines between childhood friendship and adult lust.
As they explore their newfound physical relationship, the protagonist struggles to understand her true feelings. Is she simply indulging his fantasies out of kindness, or does she share his hidden desires? Their encounters grow more intense, leaving him questioning the nature of their bond and what the future holds for them.
