Story:
“What lovely prizes I have for myself”

Exclaimed Toujou Nozomi as she opened the door to her closet. But within the closet was not clothes, but two girls heavily bound, more specifically her friends Nishikino Maki and Ayase Eli.

The girls moaned in response, unable to reply due to their mouths filled with a ballgag, shared between them, their lips caressing each other.

Nozomi gazed at her captives lustfully, it was so easy to trick them and knock them out after their concert. Now, Nozomi had her two idol friends at her mercy.

Maki and Eli had their arms wretched out behind their backs in a strappado, their arms tied at the wrists, forearms and elbows crushing them together. Nozomi relished in watching their gloved hands waves fruitlessly in an attempt to reach knots in their bondage. More rope had been deviously connected from her wrist ropes to a crotchrope tightly cleaving each of the private parts, causing more erotic moans to come from the girls. Each of their right legs were folded and tied to their cute asses, forcing them to balance on high heels. More ropes accentuated their bodies in a harness. To top it off, two vibrators on a teasingly low setting were torturing the idols for hours.

Nozomi grinned as she held up the vibrator, increasing the setting to the maximum as the two captives watched helplessly, their muffled protests being music to her ears.

“Now… I’ll be back in the morning, enjoy yourselves slaves!”

The art is by EUDETENIS, but the story is by the person who commissioned it; an English-speaking idol loving bondage fetishist who apparently has very deep pockets by the name of Donny.
Honestly, good for Donny. Most wealthy people who want to sexually abuse teenage Japanese pop stars do it in real life, so when you think about it this is comparatively very ethical.
I just hope he never finds out about Tokimeki Idol, my favorite character in that game is Nonono and I imagine he'd be all over her just from her name alone.
