[Izumisou #5 (Rustle)] Lowteen Complex [QuickAndDirty] [Decensored]

Nao's jealousy boils over the moment she spots a flirty older woman chatting up her brother—but a sneaky idea strikes, and the twintailed little sister decides the only way to win him is to bare herself, spread her skirted thighs, and offer him her virginity with a breathless invitation. Their sibling tryst builds to a sweat-slicked finish that leaves her small body twitching and spent, legs splayed wide as every moan carries through the walls. Meanwhile the very woman she envied lingers outside the door, delighted to have found 'great material' for her next book—suggesting she may have orchestrated the whole thing.
