[Miyahara Mimikaki] Honto wa Nakayoshi [Wrecking Army]

Mami-chan, a second‑year schoolgirl, is seduced and taken advantage of by her older cousin Onii‑chan and his sister Yuriko‑chan in a heated incestuous encounter that includes anal play and a full‑fisted threesome. Despite her protests, the sisters bind and push her into increasingly degrading positions, their glasses‑wearing cousin watching with a mix of amusement and desire as they call her “stupid” and revel in her helpless cries. The story ends with the trio locked in a relentless, perverse rhythm, leaving the reader to wonder how far the cruel game will go.
