Katerina, 1987, returns home tipsy, crashing on the couch. Her brother Pyotr, 1986, watches her sleeping, his eyes drawn to her curves. Unable to resist, he gently parts her legs, revealing her lace panties. He strokes her thigh, lean fingers tracing patterns on her soft skin. She stirs, moaning slightly, pushing her hips up. Encouraged, he slides her panties aside, exposing her glistening pussy. He dips a finger in, feeling her warmth. She's wet, ready. Unable to hold back, he unzips, unleashing his hard cock. He guides it to her entrance, pushing in slowly. She's tight, but she takes him, her body responding to his thrusts. He fucks her gently, then harder, unable to control himself. She wakes up, gasps, but it's too late. He's already cumming inside her.
