[Primal Gym (Kawase Seiki)] SAOff FULLCOLOR (Sword Art Online) [Full Color]

Suguha Kirigaya dons horns, a bell collar, and a cow-print bikini for her onii-chan, turning a playful cosplay into something far more intimate between cousins. What starts as teasing paizuri—her heavy breasts slick and warm around him—spirals into breathless cowgirl riding, milky lactation, and deep nakadashi finishes that leave her trembling and dripping. Across every vividly colored page, the siblings trade confessions of love between rounds, their affection as overwhelming as the appetite that drives them back to each other again and again.
