Fleur - Hentai anime adaptation of the Nanao manga of the same name by PinkPineapple Studios. 

The protagonist of the story has long been in love with his editor Shinonome-san. She is a kind and caring woman with very sexy forms. Onejy the hero, as usual, was masturbating in the bathtub, imagining her naked. Unexpectedly, the door was opened by Shinonome at a rather "lucky" moment, when the hero was already ejaculating. Some of the semen fell on the girl and quite dumbfounded her. This was the beginning of a close relationship between the hero and his editor.
