Commission for HeavenAndEarth80

Kurusu Kanako
Ore no Imouto ga Konna ni Kawaii Wake ga Nai

Summary by HeavenAndEarth80 :
Ayase and Kanako just returned from the beach, where they went with Kirino and Kyousuke. At the beach Kanako had been trying to get Kyousuke's attention with her new bikini. Kirino managed to keep Kanako away from Kyousuke to some extend, but Ayase still wanted to punish the redhead for trying to steal Kirino's (and her) special 'onii-san'. Ayase invited Kanako to eat dinner with her. Kanako accepted the offer and they ended up in Ayase's room. That's where Ayase showed her true colors. Before Kanako could react, Ayase put her handcuffs (which were reserved for Kyousuke up to this point) and tied up Kanako.
