[Kayashishi] Elf Girl Gets Rekt [sakurei]

A bratty, pointed-eared elf girl with a smug grin boasts about wrecking a man until her teasing role completely collapses. She ends up flushed, drooling, and thoroughly broken, servicing him orally before taking his massive shaft deep inside until he floods her womb. The x-ray panels and the man's dazed confession—"I really came"—seal her defeat, while the afterword cheekily admits the world has no real setting beyond doing lewd things.
