[Arimura Daikon] Just One Thing (COMIC Anthurium 2023-06) [Redlantern]

Twins Akino Chifuyu and Chinatsu couldn't be more different—the accomplished sister with a swinging ponytail, a big ass, and a huge, soft chest that aces every exam, and the overlooked twin who feels she has nothing of her own. When both girls set their sights on the same schoolboy, Chifuyu gets to him first, jerking him off with an apologetic smile before wrapping her enormous breasts around his cock and sucking him dry in a dominant, cum-soaked paizuri session. But a breathless late-night phone call hints the game isn't over—the losing sister may have already gotten her hands on him, and 'just one thing' might yet be hers.
