The rain pours outside as Mittsuri and Yumi's taboo desires consume them. They strip, their bodies slick with rain and lust, as their stepbrother watches, his cock hardening. The sisters take turns riding him, their wet pussies sliding effortlessly along his length. The room echoes with their moans and the sound of flesh slapping against flesh. As their orgasms approach, the stepbrother pulls out, painting their faces with his hot cum, leaving them breathless and ashamed, yet yearning for more.
