Doubly na Kanojo ~H na Jonan ka Dou ka wa Sateoki~

The protagonist's life is a series of disasters, all tied to his encounters with women. Every girl he meets brings a new kind of wild trouble—from offering to unzip his pants to manual stimulation, and from sexy school swimsuits to maid uniforms and cheerleader outfits. Sure, these might sound like good problems, but for him, they're a hilarious mess of steamy situations.
