Itou-san to Buruma de Ecchi!

"It's definitely because of these bloomers..."

In the near future, a certain engineering school's student council is headed by a girl named Itou. One day while sorting things in the storage room, she comes across a relic from a bygone era... a pair of bloomers.

Her kouhai Inaba suggests she put them on -- as a joke, really -- but the garment was enchanted with a terrible, sexy curse... It turns Itou into a huge slut! Inaba's not exactly complaining, though...

Sex with the bloomers still on, bloomer bukkake, those are expected, of course, but there's also a second cursed item, a gakuran-style uniform, and together the two objects throw everything into chaos!

The student council gets swept up in the sexy storm... what will happen to Inaba the perv and the ever-less-uptight Itou...?
