[Hotate-chan] Ani no Kimoi Gendou ni Honki de Don Hikukedo Nandakanda de Kotowaranai Imouto [BTD Translations]

Mizuki's plans with friends crumble the second her big brother corners her at the front door begging for another favor, and no matter how loudly she protests, his little sister can never actually refuse him. What begins with him desperately humping out a load against the soft smooth hollow of her underarm escalates into a full pounding that sets her huge breasts swinging, her furious scolding of 'seriously, die!' dissolving into breathless moans as he praises her unbeatable body. And when he finally empties himself inside her gushing pussy, her tsundere mask slips completely—whimpering that she wants to be with him forever while he already plots going raw next time.
