The main heroine of the hentai is a girl named Shirogane Irina, who is half Russian and half Japanese. She is not a quiet character and likes everything extreme and unconventional, including exotic sex. Irina has an incredibly sexy body - white pale skin, rounded firm tits and a huge weighty ass. Of course she has a lot of suitors, but only one lucky one - Sado Yuji became her chosen one.
