Here is a Masaru x Allister doujinshi that I got from Suruga-ya! I love Allister so much, he is my favorite character from Sword and Shield. Anything I find with him, makes me ecstatic! Anyway, this doujinshi is pretty short. Masaru and Allister are hanging out in a cave, then Allister takes off his shorts for some reason. Masaru then pushes him down and kisses him. Then things escalate from there. The art is cute, a little chibish and simple. Hope everyone enjoys!
