Ise-itoko

Life has finally become a bit peaceful for Issei Hyoudou. Taking advantage of that opportunity, Leiko decides to spend some time with her younger cousin. But she soon finds out that spending time with her 'Ise-itoko' wasn't as normal as she hoped it would be. Issei x Ophis, mild one-sided Leiko x Issei.
