Finding out my sister is a total nympho was a shock, but it turns out to be a massive win. Her friends are all just as loose and keep coming over, practically begging for it. I might stay away from my sister, but her horny friends? I'm diving right in.




















The bunk bed scene was pretty good, and since I only have a brother, I'm actually envious of having an older sister. But the younger brother and his friend really killed the mood. It's annoying, and the way they framed the actress as just a 'big-breasted slut' really ruined it for me.
Just as the title suggests, it was full of big-breasted women. And they all had beautiful breasts, too! Ruka Ichinose, Rina Fukada, and Sumire Matsu are in it, but personally, I was more excited by the other actresses! (I don't know their names, though...) However, there's no intensity and the sex is monotonous, so it's undeniable that it relies a bit too much on the big breasts.
*A harem fantasy project based on the situation, ``What if all of my sister's friends who came to my house had big breasts and were sluts?'' The main character Yuta's older sister Mari (Ruka Ichinose) is a female college student attending a famous university, but she is a big fan of sex. When Yuta's friend Kenji, who happens to be visiting, learns that he is a virgin, he secretly performs a blowjob while his brother is not home. Also, Mari's bimbo friends (Sumire Matsu and others) come to Mari and Kenji's common room almost every day and have sex with Kenji to kill time. The sight of him spending days full of sex with the finest big-breasted gals his sister brings to him without even having time to dry his cock can be described as a ``dream world.'' Although it can't be denied that the development is quite "opportunistic", if you like big breasts, this is a book that will satisfy you.
