Arietta Elfinrine (アリエッタ・エルフィンリーネ), from the eroge Himekishi Olivia (姫騎士オリヴィア). Trained on game cg rather than the OVA. Will be censored so tag as needed. Adding "pink dress" and "elbow gloves" to the negative helps with getting alternative outfits. Seems to work best at 0.8 strength. Elf milf is cute too.
