She would come to him to ease her urges, and the attacks would strike without warning. She would be especially cranky when in heat, which her smaller mate senses, quickly trying to calm her in order to saw his own skin.
In the morning or when she came back and her noticeable annoyance showed, her mate would quickly crawl between her arms and legs, making his way to her groin where he would lick her irritation to ease her urge.
It would often result in more, as the negress rolled her mate over and used his stiffning cock as a scratcher to scratch her inner itch. If he did not calm her down, it would result in his skin flayed and others unnecessarily harmed by her temper.
Satisfied, she curls up with her mate, cum stuffed and exhausted, the cracker waiting for the next time her heat comes back, now a slave to her urges as his life depends on her mood.
It does not take long before the negress is pregnant and needs the help of her sisters to hunt for food since her cumbersome, belly makes it hard for her to run.
As payment for the food the negress allows her sisters to use her mate, the first encounter scaring the cracker as now two, new rather large predators that it does not know enters his space.
While she eats, her sisters sniffs and licks the tiny cracker to identify it, playing with him at first with gentle pushing and notching, making the frighten cracker whimper as he burrows himself into the soft flesh of his owner in a silly attempt to hide from the monsters.
He cries out to his master, but she does not listen, allowing her sisters to bite his ear and pull him out into the open as they pin him down into the ground for further exploration.
Licks and whimpers entice for more, and soon enough they get the cracker erect and begin to use him, violating him without mercy, treating him like a toy, as they squeeze three loads out of the poor animal, leaving him panting and tired in a poodle of juices.
Wounded, he crawls back to his owner, hoping to get a bit of comfort and food remains from her which luckily, she does. Safe again, the cracker rests, hoping that such violation would not happen again, feeling how sore his genitals have become from it.
Unfortunately, the acts would last until his mate gave birth, having no say in it whatsoever.
