[Kerberus] Demon Quest [Full Color]

A bedtime legend about a hero bloodline doomed to slay a reviving demon lord turns out to be family history: when the latest hero finally corners her ancient enemy, a body swap leaves each wearing the other's skin, and the demon — armed with the hero's own body — decides a hundred rounds of payback are in order. Bound wrists and tearful protests of "can't you be gentle!?" give way to drooling, cross-eyed surrender once the dwindling counter of "99 times left" dissolves into "?? times left." The epilogue brings it full circle at the kitchen counter, where the hero, now a curvy horned housewife with a kid to hide the truth from, squeaks under a squeeze of her heavy breasts and still answers "want some tonight?" with a sure ♡.
