Due to recent misbehavior, Ashley was to remain gagged at all times. This rule applied even when Darren, her boyfriend, was at the office, and it was enforced through cameras that were setup throughout the house. Not that it mattered much, Ashley was usually kept in a strict hogtie whenever Darren left home, preventing her from removing her gag.
At first, it had started with her familiar ballgag. While it was quite large, Ashley had grown use to the size, and was now able to control her drool to a manageable level. However, Darren had decided to increase his cruelty during this past week, using panties from girls he had fucked in their house (while Ashley was bound downstairs) to stuff in her mouth, using one of his ties to keep them in place. Ashley especially despised having to listen to Darren fuck these other girls while she got absolutely nothing. She was pretty sure he was keeping his door open to allow the sounds of their moans to carry downstairs to her, allowing her to hear almost everything.
One of the girls, Nelly, was Darren's coworker, and came around about once a week for a long fuck session after work. She was the worst. Nelly knew about Ashley, and would pay Ashley's helpless bound body a visit before and after she went upstairs to Darren.
Upon seeing her, she would pretend in a false voice how excited she was to see her, and explain to her in a nanny-like voice how she was going to pleasure Darren, and how Ashley would do well to stay put and listen, that maybe she'd learn a thing or two. With a wink and a pat on the head, Nelly would then skip upstairs to receive Darren's cock. Always in her pussy, and always cumming from the penetration. Ashley hated that part too. Not only did Darren never fuck her pussy, but she was unable to cum from penetration, and it made her furious that Darren would allow other girls to do so, especially Nelly.
