Now and then she’d
have more debased fantasies. There was a man in these dark thoughts, someone
firm but cruel. She imagined his control over her like a black cloth, covering
her completely. He would hold her down by her throat while he fucked her and
when he was done he would tie her up naked at the foot of his bed. There were
other things, how he trained her to crawl and behave like his pet. She imagined
resting at his feet after a long day, or going for walks in the evening with a
collar and leash about her neck. Then one day he told her because she was his
bitch it was time to breed her like one. He brought in a male dog, and she felt
a wave of panic when the dog came close and started to lick her naked and eager
body. His tongue was thorough and stirred her lust despite her best intentions
to remain unphased. She found herself spreading herself open, while her owner
watched her helpless display. She had always been a bitch in heat, she just needed
to be shown how much.
