SIS-094 - I had a massive orgasm while masturbating and now the vibrator is stuck!? Please! Help me! Sister asks her brother for help while bathing

*First of all, just the scene at the beginning where Hoshizora Kamikawa is so excited while holding the box of vibrators she just received was enough to make me drink three bowls of white rice. It was too cute. And all three groups had a good relationship as siblings. I think it's like we're having sex on a regular basis, so it's like we're half sex friends. Thanks to that, the story progressed a lot and I think it became more practical. I mean, Kamikawa-san has a super beautiful butt! It's the best! ! !
