[Poncocchan] Get-Along App Ch.1 (Yarashii Kibun ni Naru Appli Ane to Ore to Imouto to) [Black Grimoires]

Daichi's sweaty after-school workout in his underwear earns nothing but disgust from his sister Miku, who barges in to announce dinner and brands him a pervert—but the Get-Along App glowing on his phone has other plans for their bickering household. Suddenly Miku is the one asking to strike poses for his camera, blushing as her bratty resistance melts away, and soon her big breasts are bared and her soft thighs spread while her brother apologizes that he can't take it anymore, pounding into her and keeping the phone rolling through every shameless moan. A mind-controlled sibling tryst where dinner can absolutely wait.
