[Yoshida Tobio] The Kasuga Sisters -Eldest Daughter Chapter (Onee-chan to no Himegoto ~Ireru Toko Wakaru?~) [KenGotTheLexGs]

When young Isao moves into the spare room at his father's best friend's house, he expects hospitality—not Akari, the curvy eldest Kasuga sister who crowns herself his personal 'boobie mentor' and wastes no time cornering the flustered boy with teasing questions and escalating dares. One dare leads to another until she's got him pinned beneath her, repaying his embarrassment with her mouth and hands before riding him to a messy, breathless finish that leaves the shy shota thoroughly educated. With her younger sister Kaede still waiting in the wings as his study tutor, this household has plenty of secret lessons left to give.
