A prodigy

After only an hour she was already easily fucking her face with the dildo. Tears were filling her eyes with every thrust, but Delia did not slow down. She had to be the best cocksucker there was, or he wouldn't come back to let her do it on him. She had to swallow this cock, even if it was only a dildo. Deeper... Deeper. Then she finally succeeded to put the 8 inch dildo so far inside her mouth that she could close it. She smiled, and quickly ran in the bathroom.

She could see herself in the mirror. The dildo was easily viewable in her throat, but her lips were closed. She silently counted how long she could keep it inside. After 16 seconds she had to open her mouth to breath and the dildo slid out.

She swallowed the salvia that had gathered in her mouth and took a deep breath, then she tried it again.

The next ten minutes were nothing more than taking it deep in, followed by a few silent seconds and then heavy coughing as it came out. Her face was a mess. The bit of makeup she had applied was ruined by the tears and salvia that was all over her face. A good bit of it was on her titts now.

She was sure, if she trained like this every day, for every job, she soon would be good enough to service a real cock.

Of course. Service a real cock. That is what he must have meant.
"Take care of everything around the house, like you usually do."

Those were his words. She just now understood them. She was being told, that she had to train on every person and every object that would fit the job, so she could become better.

So this silly dildo was barely enough. She had to suck bigger things. Put her tongue around them, and her titts of course. Oh but how should she train the ass jobs, without a real dick. How could she tell if her ass was being tight enough to hold it between the cheeks pleasureable, and the same with her titts.
