[Dekosuke] Deep secret Sayo-chan [HTranslation83]

Sayo kneels before her grandfather, swearing to give him her heart and body to secure the future of their lineage, while his lewd demands and her eager, ahegao‑filled compliance expose a dangerous, incestuous tension. He forces her to swallow his thick, plump tongue and later his swollen penis, the scene erupting with sweating, stomach deformation, and a desperate plea for deeper pleasure that highlights the sheer magnitude of their forbidden act. The lingering shame and devotion echo through each panel, promising an intense, erotic climax that will leave both characters breathless.
