a phone call from her older sister, whom i've only met once, suddenly saying "i missed the last train, can you let me stay?" she comes over in a drunken state and keeps touching my body. i can't refuse and let her into my one-room apartment, but there's no way nothing will happen sleeping in the same bed...! "there's a gap and it's cold, can i cuddle?" this is a sign of seduction, isn't it!? having sex with her older sister until morning in one bed! super sex until morning, over and over again! i can't stop this sex! a single work where the little devil goddess jun explodes.
