The story of a busty, anime-loving NEET older sister who emerged due to the occasion of her parent's remarriage, where her naive virgin younger brother became irritated by her defenseless breasts. The best embrace and the lifelike masturbator made a comeback, leading to the brother being impregnated forcibly multiple times and made to creampie. Haruna Noa

In recent works, there is a strong tendency for characters to hide their faces, but I found characters like Noa who show their faces normally more attractive. The use of masks is prominent in the works, and there were few scenes of counterattacking impregnation, but I wished to see more scenes of enjoying Noa's big breasts and creampie. The theme of sexual situations changing due to changes in family environment is interesting, and the development of a lewd relationship between a virgin brother and a busty otaku sister is exciting. I hope to see a more intense portrayal of squeezing Haruna Noa's big breasts to enhance the climax of the entire work.
