Despite her menstrual flow, she's insatiably horny, craving the intense pleasure of anal. Her partner, knowing her desire, agrees to indulge her. She straddles him in cowgirl, guiding his throbbing cock to her tight, untouched asshole. Slowly, she pushes back, taking him inch by inch, moaning as her anus stretches around his thickness. Blood mingles with their juices as they fuck, the room filled with the wet sounds of their bodies colliding.
