Amano Yuika (天野結華) from Dojirou's mangas, InCha Doushi no Sex ga Ichiban Eroiyo ne (陰キャ同士のセックスが一番エロいよね) and InCha Doushi no Tsukiau Chokuzen ga Ichiban Eroiyo ne (陰キャ同士の付き合う直前が一番エロいよね). Interestingly, google translate of the kanji and Danbooru have her name as Amano Yuka but the manga has the furigana above her name as あまのゆいか, which is Amano Yuika. I've gone with Yuika here.

Trained for 2440 steps from 61 images, includes some NSFW so be aware.
