MIDA-090 The lust-crazed older brother gets fully aroused again after seeing his female friend who came for an overnight stay…! Please…! Stay calm today…! His flustered younger sister, Izumi Momoka, secretly helps him out

My big brother is at it in his room again…Yes, this brother of mine is such a lust-crazed monster that even I, his younger sister, am completely shocked.

Today I’m having a sleepover with my friends at home, too… If they found out about this, they’d never want to see us again!

[Secretly calming down my unstoppable big brother again and again, 14 times in total!] I have to do something to control that thing somehow… No matter how many times I try, it keeps bouncing back to life! As I soothe my brother’s overwhelming urges again and again, sometimes with affection and sometimes more intimately, that huge, tireless energy starts to soften and he becomes completely smitten!? This is bad… I’m starting to feel it too… It turns out the two of us, brother and sister, were both far more driven than expected, and our chemistry was just too perfect! In the end, I ended up volunteering to take care of my brother’s needs myself…
