Can't find this particular doujin, I've looked everywhere

It's a vanilla doujin with an a guy who has a crush on this busty elf girl with braided pigtails? She gets turned on from her ears? Kakkoi..Yayoi...I can't remember the title, but the art was really good and I wanna use it as reference, if anyone can find it I'd really appreciate it.

It's from the "Cute Devil Girlfriend" Tankouban by Hisasi. The story is called "Crush" If you want to buy it, it's available on EManga.com as a physical or digital book (PDF, EPUB, CBZ, etc. is offered).
