Just barely.

Amanda had never before cursed the slow speed of the elevator. She knew she could have been much faster taking the stairs, but the toy inside her slippery sex made a quick ascent nearly impossible. Now she could, of course, remove the vibrating object, but playing by the rules was half of the fun of the games she and Rose played. No, the vibrator stayed firmly inside her sex, merrily humming away. Well, firmly, as firmly as she could manage, with the wetness of her pussy making it very easy for it to keep sliding out. For the first time this night, she regretted not wearing any underwear, she wanted to be extra sexy for Rose, and it was biting her in the ass right now. Finally, the elevator reached her floor, and the doors opened with a soft ding. Not wasting more time, she had a scant three minutes left, she rushed to her apartment door as fast as she could. She slammed her hand on the scanner near the door, and a second later, the door opened.

She strode inside, letting the door close on its own, and walked straight towards her bedroom. Various lights around the house came on as the motion sensors detected her rushed movements, partially illuminating the apartment while leaving other rooms in the dark. Once in her bedroom, she opened her closet and pulled out a few objects of clothing and threw them on the bed behind her. A sexy bikini. A more modest, but still revealing and skintight one-piece swimsuit. And some extra sets of clothes and underwear. She already had an overnight bag in her trunk, but that was for a few days. If they decided to extend their time together, she needed more clothes. She picked up her backpack from the floor and began stashing the items in them, not really caring to be neat or precise, she was on a clock after all. When she was about to put the last piece of clothing in her bag, a modest but classy string, she hesitated briefly. Her frantic movements made the toy slide out constantly, and she had to stop regularly to push it back in, making her lose more time. She quickly made up her mind and stepped into the piece of underwear. As she pulled it up under her dress, she felt the soft fabric caress her hot pussy, and sighed in relief as the vibrator was pushed back into her slit.

Slinging her backpack over one shoulder, she walked towards her office/workroom, where she kept her portable computer used for programming, as well as a myriad of objects. Some were gifts from satisfied customers, the very first produced after she had finished programming it to their satisfaction. Others were work-related, and still in an experimental phase. She walked towards a corner where she had stashed a bag given to each member of her division as a thank you from a large producer of adult toys. She had yet to test any of them, and the coming days would be perfect. She put her computer in a side pocket and picked up the bag with her free hand. She did a quick count in her head and cursed silently. Thirty seconds left, she had to hurry if she wanted to avoid {me}'s punishment.

She hurried out of her apartment, her steps much quicker now that the string she wore held the vibrator in place, and after locking the front door, rushed towards the elevator. With luck, it would still be on her floor. She pressed the call button, and without delay, the doors slid open, revealing the elevator was indeed still here. Twenty seconds later, and Amanda stepped out through the lobby doors, into the cool night, and walked hurriedly towards her car. As she approached the vehicle, she saw that Rose had gotten out, and was leaning against the side looking at Amanda's phone. The occasional swipe of her finger told Amanda that she was probably looking through her photo's, they did that often, and the two friends rarely kept secrets from each other.

Rose looked up from the phone as she heard Amanda's rapid footsteps. In the dim light of the nearby lantern, Amanda could just barely make out the slight narrowing of Rose's eyes. Was something wrong? Was she too late? Did she see something on her phone that she didn't like? She walked up to Rose, and stoped in front of her, breathing heavily from her rushed walk, and the insistent vibrations between her legs.

'So, did I make it in time?'

Rose taped the screen of the phone once, and turned to let Amanda see it. The timer was stopped at two seconds left. A triumphant smile formed on Amanda's face as she looked at her friend. She saw Rose look back at her with satisfied approval, but that all too familiar glint of deviousness had returned as well. Amanda's pussy convulsed around the vibrator at the thoughts of what those eyes usually mean, and she was thankful for the string she put on to help keep the thing in place. Her eyes widened as she realized her mistake; she had kept the string on. There was, of course, nothing preventing her from doing so, but the rules of their games meant that they follow the dominants commands. And she was not told that she could put on underwear.

Rose must have noticed something was different when she walked back without any problem when she clearly had some difficulty leaving the car. Amanda moved towards the trunk, and put the two extra bags in it, placing them next to her overnight bag. She closed the trunk with a loud thud, and when she turned, found that Rose had moved to stand beside her. When Rose spoke, her voice was calm and soft, but Amanda could hear the disappointment underneath.

'I think someone has been a disobedient girl. You walked out with far less trouble than you did going in. Turn around and put your hands on the trunk.'

There was no point denying the claim, they both knew Amanda was in trouble, this was Rose playing her role as the one in charge. Amanda turned around to face the trunk and bent forward so she could put her hands on top of it. Her breasts swayed slightly as she took a new position, and she stuck her ass out as a result. She felt Rose's hand slide across her thigh, going higher and higher until her fingers traced the outline of her string. For a few moments, she rubbed her fingers across the soft fabric of the undergarment, making Amanda squirm and pant. Never stopping the gentle tease of her lower lips, Rose spoke again, her voice close by as she leaned down slightly.

'As I thought, you decided to cheat. Did you think I wouldn't notice? Or did you simply forget to take it off again before leaving the building? Either way, I think you deserve some punishment for this.'

Amanda felt the hand trail upwards towards the top of her string and after a quick pull, felt the flimsy garment fall down her legs, exposing her bare pussy once again. She was surprised however when Rose's hands gripped the hem of her skirt and worked it up until her firm ass was in full view. She started to protest, but her friend's soft hand massaging one of her buttocks quickly turned it into a soft moan.

SMACK!

She made a cute yelp as Rose's hand came down hard onto her ass. A few seconds of caressing the other side, before;

SMACK!

This time she was ready for it, so she managed to remain silent, but the thought of being spanked on her bare ass in front of her own house, made her arousal rise to new heights. A single finger slid across the outside of her pussy, gently stroking the sensitive parts of her sex. Back and forth it went, stoking the fire between her legs higher and higher.

'Yes, a spanking is a fitting punishment for a naughty girl who decided to break the rules. Let's say; One spank on each cheek for each minute you cheated out of the game.'

SMACK!

Without warning, Rose's other hand came down hard on Amanda's ass, making the other girl rock a bit under the ****. Meanwhile, the hand stroking her pussy lips had moved up, and a single finger pressed gently against her clit. Amanda closed her eyes as a fresh wave of pleasure radiated from between her legs.

SMACK!

She opened her eyes in shock, the pleasure no longer on her mind. She turned her head to look towards Rose and saw the seductive grin she knew and love.

'Eyes forward love, you're going to take it not knowing when the next hit is going to be.'

She turned to look forward again, just as Rose pinched her clit. It was soft, and gentle, and caring, and her pussy convulsed from the pleasure. She felt the vibrating dildo slide out and was just about to fall to the ground when it stopped. It was slowly being pushed back into her pussy, and she once again moaned as the vibrations stimulated her dripping slit.

SMACK!

A sharp hit to her behind pulled her back from the pleasurable sensations. A few seconds of nothing, before the vibrator was being removed. Rose took her time pulling it out, making sure Amanda felt every second of it as it left her cunt. When it was just the tip that remained inside, she waited for a single breath, before pushing it back in in a single motion. Amanda arched her back and a loud moan of pleasure echoed across the parking lot followed quickly by a second sound.

SMACK!

'Now how many was that? Watching you act like this makes it so hard to keep count.'

That was a lie, of course, they both knew Rose knew perfectly well how many times she had hit Amanda's shapely behind. But this was a game, one they hadn't played in a year, and they had their part to play in it.

'That was six, three to each side.'

Amanda's reward for answering was the vibrator being removed from her pussy, before Rose slid it back and forth across the outside of Amanda's sex. Amanda closed her eyes again and lowered her head against the cold steel of the trunk, she had trouble enough holding her orgasm back as it was, but this was not making this any easier. For a full minute, Rose tormented her with the sex toy, until she felt her body begin to shake from the pleasure.

SMACK!

SMACK!

Two hard smacks against her ass served to push the overwhelming sensations between her legs down, and the orgasm she was so close to having was now just out of reach.

'Not just yet. This is not my home.'

Amanda wailed softly in frustration. Her pussy was burning with desire and need, was this what Rose had to go through during diner? She may have gone a bit overboard by giving Olivia control over the toy. The sound of something being placed on the trunk drew her attention to her side, and she recognized her phone. The screen was brightly lidded with the app controlling the vibrator activity. One of Rose's slender fingers touched the marker regulating the power, and she saw it slide up a good chunk. The resulting increase in vibrations between her legs made her wail again as the pleasure threatened to overwhelm her.

SMACK!

The sharp sting of Rose's hand against her reddening ass distracted her from the mounting pleasure. For a few seconds at least. Her hips were gyrating as she worked to push the toy as best against her pussy as she could. When she found the right spot, she was allowed a few blissful moments, before;

SMACK!

Again, the spanking of her ass served to distract her just long enough to stop the orgasm. The vibrations disappeared as Rose removed it from her dripping snatch, and Amanda's body relaxed as the constant stimulation left her body. Until with a wet squelch, and a strangled cry of pleasure, the toy was inserted back into her pussy. The sensations were brief, however, as Rose slid the power marker all the way down, making the vibrator fall silent.

A pair of warm, wet lips were placed against one of her ass cheeks, as Rose pressed a loving kiss against the burning skin. She repeated the gesture with the other cheek, before pulling the skirt of her dress back down. She was helped back up by Rose, and the two lovers simply stood there, embracing each other. After a moment to collect herself, Amanda stepped back and looked at her friend. Seeing nothing but love and care in Rose's eyes, she knew she had done well in taking the punishment. It was a brief moment between them, one born from several years of sexual experimentation, but that one look told them all they had to know about the other's thoughts.

They couldn't wait until they had reached Rose's home.

Rose bent down to pick up Amanda's underwear from the ground, and after reclaiming her friend's phone from the trunk, walked towards the passenger's door.

'Shall we? The sooner we get home, the sooner that slutty cunt of yours is allowed to cum.'

Amanda felt a shiver of desire running through her body, the sheer lust and promise Rose had managed to instil into that one line was enough to make her pussy quiver around the smooth toy. She too walked towards her side of the car and managed to get in without losing the vibrator. A short minute later, and they were ready to leave. Amanda placed her hands on the steering wheel, and as expected, Rose snapped the cuffs once again around her wrists. Her hand briefly disappeared between Amanda's legs, and she felt a sharp nail scrape across her clit. She opened her mouth in a surprised gasp and was extra surprised when Rose shoved the flimsy material of her string into her mouth.

'It would be a waste to not use it. Not after all the trouble, you went through to get it. Now, let's go.'

For extra emphasis, she pressed a button on Amanda's phone, and the vibrator gave a quick, but powerful pulse inside her pussy. Amanda moaned around her makeshift gag but began to drive the car towards Rose's home. A thirty-minute drive, ten of which through the city itself. Traffic lights. Long, straight roads, and barely any traffic to be mindful of. She knew for sure that Rose would torment her whenever she could.

And she loved her all the more for it.
