In order to cheer Haruto up after his anime was such a flop, Itsuki gets him as well as Nayuta, Miyako and Chihiro together so they can play a TRPG. Itsuki usually plays girls in games, but for some reason, Chihiro makes out their character to be Itsuki’s character’s little sister, which leads to Nayuta and Miyako also making their characters sisters of the other two. Haruto becomes the GM and does whatever he wants.
My tongue slips in between Onee-sama's lips.
Meine Zunge verdrängt Onee-samas Lippen
und dringt in ihren Mund ein.
Mi lengua saborea
los labios de mi hermana.
Mi lengua saborea
los labios de mi hermana.
Je pénètre de ma langue
la bouche de ma sœur aînée.
La mia lingua scivola dolcemente
tra le labbra della mia sorellona...
Minha língua desliza entre
os lábios da Onee-sama.
Мой язычок
влетает в ротик сестрицы
