Anna slowly relaxed more and more, letting it slide deeper into her throat. She soon forgot about how she was doing this naughty thing with her father and just focused on the pleasure of sucking on his meaty cock. Her pussy twitched and moistened all over again as she grew aroused. Later of course she would burn with shame at this, but for now it was easier just to be turned on. It only felt more arousing with someone watching them. Anna sucked harder, putting forth more effort.
