Her Master had been building her up to this evening for months; bringing friends or other Masters and their slaves around to play. These had all been very fun, but all together fairly casual. She had been promised that this evening would be very fulfilling "In any and every way a filthy whore like you could wish for".
Her instructions for the day ahead were straightforward, ensure that she would be ready for a proper inspection and was thoroughly excited for the evening, and follow any instruction sent to her throughout the day.
She woke early, tossing and turning in the dawn trying to sleep, unsure in the soft light why she was so anxious. With a buzz of her phone she remembered very quickly, and opening it she read a message saying good morning and that she was going to go shower from her Master. With hot water beating down on her she started to shave carefully, fingers lingering around her pussy a little longer than strictly necessary, but not so long that she would be embarrassed to answer any direct questions about her ability to behave. Once she was happy with the smooth surface of her cunt she washed the rest of her body briskly, attempting to minimize time where her master was waiting for a text.
As she re-entered her room her phone buzzed again, this time with a request for a photo of the day's clothes and a specific pair of underwear she should wear. Slipping on the lacey black panties and pondering her clothes her phone buzzed again, this time instructing her to put one of the plugs her Master leaves with her in, and to send a photo promptly.
She had taken care to wash properly but she had not expected that she would be asked to do anything so invasive this early in the day. Reaching to her nightstand drawer she pulled out a bottle of lube and a plug quite wide around the base and longer than most, in doing so realizing that her Master must have removed the other toys from inside earlier that week. Peeling the panties part way down her thighs she took a picture of the wetness already trailing between her cunt and the thong and sent it to her Master before applying a small amount of lube to her index finger. Rubbing it in and around her hole she shuddered slightly at the cold wetness before adding more lube to the head of the toy and beginning to press it into her ass. At first it seemed unlikely that even a centimeter would enter her hole but with some deep breathing and a small amount of relaxation through stimulating her pussy she was able to push it deeper and deeper in. As the toy reached closer to completely entering her the mixed feelings of pain and pleasure deepened, until with a final push and small squeak she managed to completely fill her ass with the oversized piece of silicone. Slightly out of breath she sent a short video of her smiling face trailing down to her obviously wet cunt and very full ass to her Master. In a rush after realizing the time, she grabbed a thin white blouse and a tight black skirt and threw them on in a dash to get to work on time.
Sitting in her car she realized that she had forgotten to ask about her outfit and squirmed somewhat thinking of what that might mean later that evening, but she had a lot of work to do and could not afford to be any more distracted than she would already be. As she pulled into the parking lot of her office her phone buzzed again, this time with her Master wishing her a productive day at work, and a reminder to leave her cell close enough to hear it throughout the day.
