I had known that it would happen eventually. In fact, I was absolutely certain that it would happen eventually. And it did.
It had begun Wednesday night, just before midnight, when my big brother had been perched between my thighs, eating me expertly once again, making me cry out in the darkness of his bedroom while my thighs crushed his ears into his skull and my fists pulled at his hair. At that moment, I had not been a slave, nor even his twin sister β instead, I had been his fated lover.
That changed as soon as I had regained my senses and found myself being cuddled in his protective arms, my nectar being dotted upon my face as he kissed my cheek and forehead. Even in the afterglow, I could sense that my role had suddenly changed.
"For the next three days, you will not cum, is that understood, slave?"
That confirmed that my role had indeed changed from much-loved woman to much-loved slave.
The next three days were difficult. Thursday was not too bad, until that evening when I was ordered to keep a dildo inside me throughout dinner and my evening studying. Friday was a little worse, as I locked myself into a bathroom stall in the campus library and masturbated myself to the edge of insanity, then properly obeyed my Master's order and did not allow myself the pleasure I craved. Saturday was pure sexual torture, since my Master had swapped shifts with a co-worker who needed to have Sunday off, allowing my Master to tease me all day long, to finger me or eat me or fuck me at will and then abruptly stop just as I was about to climax.
My need was so great that I was almost in tears as I dressed for work Saturday night, and since I was the only video store staff who had absolutely no qualms about being in the adult section, I knew that I would be going behind the curtain a few times to restock or perhaps to check inventory.
