Tooma kun is a young, healthy boy who happens to be fixated in his lovely senpai, the school madona. Tooma's interest include : dressing his senpai in sexy outfits, dressing his senpai in sexy male outfits, dressing himself as a sexy girl (to match as a couple when senpai is crossdressing) and engaging in perverted punishment games via rock / paper / scissors games with his dearest Suzuka senpai....

However, is it Tooma the only one who happens to enjoy of such perverted hobbies? Or is it maybe that Suzuka has some nasty fantasies of her own as well?

Note : Between the release date of chapter 7 & 8 there it was a 2 year gap. However, chapter 8 & 9 are meant as prequel chapters that explains how the main characters came to be a couple, while the rest show their activities as established partners.
