[Minion] Anesonteihi Boku wa Onee-chan no Omocha ja nai (COMIC AUN Kai Vol. 26) {Chin²}

A little shota heading out jogging with his tomboy best friend gets ambushed by her teasing big sister, who wastes no time stripping his gym shorts down and taking his stiff little length into her mouth behind the gym. The trap springs wider when his own twintailed sister stumbles onto the scene, and soon the shy boy is trapped between the siblings—coaxed into returning the favor while his sister milks him dry. It all builds to the older girl pinning him down and riding him bareback, cooing that his small, rock-hard package must feel amazing as she demands every last drop inside.
