In the quiet town of Nis, 1979, a Serbian brother and sister find themselves ensconced in a cramped, dimly lit room. As they sit there, the air thick with tension and unspoken desires, they begin to explore each other's bodies with tentative, curious touches. The brother's hands tremble as he reaches for his sister's breasts, feeling their weight and warmth through her thin shirt. She gasps, arching into his touch, her own hands finding his hardening cock through his jeans. They're both virgins, untouched by anyone else, and the taboo of their incestuous encounter only serves to heighten their arousal.
