It started as an idea; an alternative method of making a few extra dollars.  Who cared what they would use her body for; it was money.  How naïve she had been, thinking of nothing but her financial needs.  What great idea this was yesterday.
These thoughts had long since left Cassie’s mind.  She was being raped.  Who cares that there was money involved?  What did it matter that she was the one who initiated it?  There was little doubt in her mind that this act being performed was happening to her, not with her.
From the moment she laid eyes on him, she knew.  The man’s face was a friendly one, a gentle smile playing on the corners of his lips.  Nothing, from his neatly combed hair to his twinkling blue eyes to his neat, clean clothing, suggested he desired her any harm.  But deep inside, she knew.  She knew with utter certainty that this man would hurt her.
Cassie had trembled slightly when he laid her body on the soft bed, making sure she was as comfortable as possible.  He had told her his name, but by now her mind was racing too fast to comprehend the sounds issuing from his mouth.  The moment she heard the tearing of a wrapper, Cassie turned her head away from him.  Muscles clenched, she lay in wait for the beginning of what was going to be, in her mind, her worst life experience yet.
Cassie bit her lip to keep from crying out in pain as the hard shaft forced its way into her.  It had come quickly and unexpectedly.  Not given much time to prepare, she was quite certain that this act had torn a hole in her flesh.  He held it there, inside her for a short moment.  Then she felt an odd suctioning sensation as the pumping began.  She felt as if her entire life force was draining from her.
After what seemed like minutes, the pressure switched directions and started thrusting back into her.  She couldn’t scream, lest the man stop short and decide not to pay her full price.  Deriving no pleasure whatsoever from what was happening, Cassie tried to relax herself as she mentally prepared for the steady repetition that would undoubtedly last for hours.
So here she lay after what seemed like days had gone by.  Glancing at the clock hanging from the wall, Cassie was dismayed to find that merely one hour had passed since the initial penetration.  She didn’t know how much more of this she could take, wondering if she could still charge full price if she stopped him now.  She didn’t have much time to ponder this, however, as the steady pumping abruptly ground to a halt.  Without warning, the hard probe inside her started spewing liquid while lodged deep within her.  A sickeningly cold feeling spread from that liquid inside of her, causing a nauseous reaction that almost made her throw up the contents of her lunch.
Shortly after it began, it was over again.  The man gazed down upon her as she lay there, heart racing, feeling totally violated.  After what seemed like an eternity, he quickly withdrew his instrument from her flesh, which groaned in agony after becoming so accustomed to its pressure.  A quick dressing later, he paid her the twenty dollars he owed her.  She looked down at the money with contempt.  How could she lower herself to this kind of degradation for such a paltry sum of money?  She flexed her joints, only to feel them cry in protest at the sudden movement.
As she shakily walked out of the building absent-mindedly rubbing her arm, she knew she would never forget the man’s final words to her.  “Thank you for donating your plasma with us today.”
