Daniel held his breath as he slipped through the door to his sister’s room. It was hardly necessary, he knew, since she had left for school an hour early, but it was hard to shake the feeling that she was still present somehow. After all, a significant part of her was still lying on the bed.

There, sprawled out on top of the covers, was Sarah’s pajama-clad body, dozing soundly. Obviously, her head was elsewhere, perched atop the body she wore to school. Lifting her shirt, he didn’t see why she needed this one; the difference was hardly noticeable, though she claimed it was easier to sleep with softer muscles. Wasting no time, Daniel quickly undressed the spare body; he decided it didn’t matter if she woke up. Though he could see the body had grown alert by the change in chest movement, she merely sat up without resisting. She remained docile as he plunged his fingers into her pussy, and stuck his tongue down her throat hole. She convulsed a little when he plunged the knife into her chest, but lay down obediently as he opened her abdominal cavity and caressed her innards.

By the time he was jerking off with her uterus, he was so absorbed in ecstasy that the sound of his sister clearing her throat behind him might as well have been a distant birdsong.

It’s not like she was using it, he complained to himself while scouring the bushes for his severed genitals.
