DC Lovely's manga / #Step brothers(2)

I'm now at an age where it's normal to want to do it. It's just that...I'm still a virgin and I'm jealous of Itsuki, my brother. He's tall, handsome and popular. However, Itsuki is nothing but a pervert who loves me to the point of stealing my underwear to sniff them! But when one day I joked about him being a good-for-nothing, not even capable of surprising me in my sleep, he stared at me with grave eyes...It sucks, he's serious! This book also contains the story of the fresh, handsome senpai and a yankee with a mean face: The Lion Doesn't Refuse.

From Exiled Rebels Scanlations:Toujou Aki lives with his younger step-brother, Saku who is a university student. Instead of going home to sleep though, Saku will stay out with as many women as possible, to the point of being a man-whore. Aki, on the other hand, has a deep hatred for women, enough to make him nauseous being around them. Aki?s one secret is that he would do anything for his brother. No matter what it is. However, everything can change in an instant during the silence of three minutes.
