In a dimly lit Swiss darkroom, Corell, the eager model, is bound and gagged, ready for her first time as a sex slave. Maria19, her mistress, teases her, making her suck and deepthroat while she fucks her with a strap-on. Corell's eyes water as Maria19's cock hits the back of her throat. Her face is soon covered in saliva and spit as Maria19 face-fucks her. The darkroom echoes with the sound of their moans and the wet slapping of flesh. Finally, Maria19 pulls out, coating Corell's face in a thick, hot load of cum, marking her as her sex slave.
