Itsuki Hashima is a popular, young novelist. However, he is obsessed with little sisters and his works seem to always include little sisters, so there’s some difficulty coming up with a new series. One day, his younger step-brother Chihiro and his colleagues, Hayato Fuwa, Nayuta Kani, and fellow college student, Miyako Shirakawa show up at his apartment. They enjoy dinner, drinks, and a game. That night, Nayuta makes advances towards Itsuki, but...
Ah, my little sister's hot, 
just-worn panties taste so good.
Ah, welch Hochgenuss, dieses frisch getragene, warme Höschen meiner kleinen Schwester!
Los pantis calentitos
recién usados saben de maravilla.
Las braguitas calentitas
recién usadas saben de maravilla.
Ah! Le mutandine ancora calde che
la mia sorellina si è appena tolta! Che buone!
Ah, é tão bom o sabor da calcinha
 que minha irmã acabou de usar.
Ах, её тёпленькие, ношенные
трусики просто объедение!
