What is it about dirtying a student's uniform that feels so irresistible? Lately, I've been feeling a bit bored with just casually making love to my girlfriend, someone I've always easily embraced. So I started imagining her as she looks when going to school, and that fantasy made everything so much more exciting—I'm actually regretting not thinking of it sooner. Her name is Sora. You can remember it or forget it, either way is fine. The point is, she's just incredibly cute. She used to be quite dependent on me, but recently she's started developing her own sense of self, even suggesting we try something different. That's how we ended up doing this.
