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.
and unable to help herself anymore, 
Onee-sama lets out a moan.
Onee-samas Lippen entfährt
unweigerlich ein Stöhnen.
e incapaz de aguantar, mi hermana gime.
e incapaz de aguantar, mi hermana gime.
et Miyako, incapable de se contenir,
laisse échapper un gémissement.
non riuscendo più a trattenersi,
la sorellona si fa scappare un gemito...
e, incapaz de se controlar,
Onee-sama solta um leve gemido.
Не в силах сдержаться,
Мияко томно вздыхает.
