Manually

Pulling the vibrator back out of Dani, the girl slid a finger into her abused pussy. With the finger in up to the knuckle, she still couldn't reach her dress. The addition of another finger didn't seem to help. An evil grin slid onto her face. "Well," she told Dani, "there seems to be only one way I'm getting my dress back. I'd tell you to brace yourself, but there isn't an awful lot that you can do." Her amused little chuckle sent bolts of terror through what little was still working of Dani's mind. If the fingers couldn't reach, she realised, then the only thing that would is the girl's whole hand. She had never taken one before, concerned about the size, but now she was going to, like it or not.

The girl knelt down in front of her, head level with her pussy. Dani's juices had been flowing freely for a while now, helped on by her massive orgasms, so the girl just rubbed her hand between Dani's thighs to gather some of it, coating her hand. She curved her fingers together, tucking her thumb in the middle to make a cone shape and placed this at the entrance to Dani's cunt.

A gentle push sufficed to get the tips of her fingers in, sliding in to the first finger joint before the walls became too tight. A series of repeated pushes and pauses followed, driving the hand deeper in until the knuckles rested on the lips of the pussy. Up above, Dani was feeling very strange, the pain of the stretching blending into the pleasure from the stimulation and the feeling of fullness. Her eyes were unfocused and her breath was coming in ragged gasps.

The girl shifted her position slightly to be able to put more power into her arm. She thrust hard, slamming her hand into the cunt and forcing the labia to expand further, slipping around the broadest point of her fist. Dani's head snapped back, pain suddenly overwhelming all the other factors. As her pussy slowly closed around the intruder, drawing it deeper in, the pain subsided and the feeling of blissful fullness began to outweigh it.

As her hand finally popped into Dani, the girl smiled, the feeling of power giving her a very sexual thrill. Her fingers were now deep enough to reach the dress, but she wasn't going to let Dani go that easily. She gripped her hand into a fist and began pounding upward. The shock of the impacts was very disconcerting for Dani, made only worse when the girl took to scraping her bony fingers against her G-spot. Her conscious, thinking mind gave up the ghost at this point, handing all control over to her subconscious, which just sat back and decided to enjoy the ride.

Before long, the fisting was driving Dani back up the peak of orgasmic release. Just as she was on the brink, the girl grabbed her dress and yanked her hand back out of Dani's pussy. The sudden shock pushed her over the edge, her now distended pussy clamping shut on thin air, failing to close completely after its stretching.

The girl took the dress, now completely soaked in a mix of cum from the office guys and Dani's juices, leaving it virtually transparent. She pulled it over her head, smoothing it against her body, where it clung, held by the sticky fluids. She ran her hands over it, the sensation of it on her skin arousing her immensely. All of a sudden she threw her arms around Dani, grinding their bodies together through the thin material - tits against tits and cunts against cunts. Within a few seconds, she came as well, her own secretions only adding to the dampness of her clothing. Shuddering a little in the aftermath of her orgasm, she stepped back from Dani, who remained bound to the tree.
