[Miyazen] Brother ↔ Lover Swap (COMIC LOE VOL.10 Mini LO 4 Jikanme) [Nishimaru]

When shy Hime and the bratty Sumika accidentally swap boyfriends with their siblings for a day, a daring proposal from one freckle-faced little girl unlocks a taboo world where both pairs wind up tangled together, trading massages that grow increasingly intimate. Breathy commands and jealous smirks give way to freckled skin flushed with arousal, stockings slipping as innocence crumbles into a shared, depraved four-way that leaves Hime breathless, glassy-eyed, and desperate for more.
