MUKD-309 - Swimmer girl broken by her brother, unable to hold back today

*“Brother and Sister,” a drama version released by the same manufacturer in January this year. Personally, I liked it, so I'm hoping that this work will be in the same vein. I bought it, but there was almost no conversation between my brother and sister, it was just normal. The sex between "Chigusa Matsuyama and the actor" just continues indifferently. Honestly, I was disappointed. If you like actresses, I think it's ◎. For those who are thinking of purchasing it based on the title, I think it's a no-no.
