Mary paid the taxi driver and got out of the car.
  - Have a good night, miss -the driver said politely.
  - Thank you. You too -the blonde answered, heading towards her apartment building.
She headed to the building that rose before her, getting upstairs to the third floor, and unlocked the door with the letter "A" written. The day at the Spencers' house had been intense, since they had given a party, and Mary had had to prepare everything. The next day she would have to clean everything. Sooo lame!
"What a good time this would be to meet my old friend again." She was referring, of course, to the masked thief who visited her when she was left alone in the Spencers' house, who left her bound and gagged, and with whom she enjoyed more than ever. However, despite giving  her her phone number, she hadn't heard from her again. Not even on the news.
Mary left her backpack in her room, and took off her clothes, to put on her pajamas. She was wearing thin lingerie under her leggings and her sweatshirt. A beautiful black lace bra and red fine fabric culottes.
  - I think you'd look better  if you didn't put your pajamas over that outfit - a voice said behind her.
Mary turned, startled, to meet with a figure in black, masked, and whose eyes were tremendously familiar to her.
  - It's you.
  - Yes, dear, it's me. Sorry I didn't get in touch with you earlier, but it would have been too risky.
  - It... it doesn't matter. - The young woman answered, blushing.
 - Okay, shall we start?
 - After You.
Both women headed into the living room. The intruder carried with her a half-open black backpack, from which several ropes protruded. Mary giggled shyly when she noticed.
  - I was thinking that this time we should get a chair.
  - As you command. - Said the blonde. - Do you mind if I take this? - she added, grabbing one of the lounge chairs. - It is much more comfortable than the rest.
  - Sure.

When Mary sat in her chair, the thief pulled out a coil of rope from her mysterious backpack.

   - Now miss, if you don't mind, could you put your hands behind your back?

Mary obeyed without any question, and the intruder began to maneuver. She used a large piece to begin tying his captive's wrists. She made a special effort to make it very well tied, to prevent her from using any of the stringers to get loose.

   - Wow! This is a lot tighter than last time, huh?

   - And I have barely started - the thief answered, winking through the slot of her balaclava. She then used another piece to attach the rope that she had just tied to the rear crossbar, so that any movement was completely restricted. She decided to leave her feet for later, and chose to tie a new piece of nylon around the blonde's waist, and from this one she took another one to add to her wrists.

   - Good grief -the owner of the house proclaimed, delighted.

   - This is much stronger than last time.

   - I hope you are liking it.

   - Are you kidding? I LOVE it.

Delighted, the intruder continued with the upper part of her captive, tying ropes around her perfect breasts, as if framing them, and fixing her arms to the body. She showed greater agility than last time they met, and Mary was delighted with it. Then she continued with her ankles. After that, she bound them, with another rope, to the rear crossbar, where she had fixed his hands. She went on with the lower part of his knees, which she tied tightly again, to continue with her thighs, attaching them to the base of the seat.

   - I see you've been learning - the young woman observed, surprised and delighted in equal measure.

   - Indeed. It is never too late to learn about your job - the thief confessed - And... we're getting to the best part. Wait here. Do not move. - She added laughing, and makind Mary laugh as well, as he went to the bathroom.

While she was there, Mary took the opportunity to test her bonds, and verify that she was not going anywhere that night. When the mysterious masked woman came out of the toilet, the blonde checked that she was carrying something in her right hand.
  - This time, my panties will go inside your mouth.
Mary smiled at her captor's sentence. On one hand, the idea disgusted him. On the other, she didn't know why, she thought it was the hottest thing she had ever heard. Without wiping her smile from her face, she opened her mouth wide, as she winked at the intruder.
The thief did not miss the opportunity, and introduced her panties into her victim's mouth, who was still delighted with her current situation. Next, she took out a roll of black duct tape, and without thinking twice, began to wrap it around Mary's head, who began to moan from the pleasure she experienced at being gagged.
When she had completed seven loops around the blonde's head, she cut the tape, and put the roll back into her backpack. Next, she began fondling her breasts, and touching her clitoris with her gloved hand. Mary did nothing to stop her. Not that she could, but even if she had been able to, she would not have done it. He was enjoying herself too much.
Suddenly, when Mary noticed the unstoppable arrival of an orgasm, the intruder got up, and said:
  - Well, it was fun, but I'm afraid the job is not going to do itself.
Mary's eyes widened, scared.
  - MPHHHHH?!
  - Oh! I'm sorry dear, didn't I tell you? I have not come here just to play with you. As much as I would like to, I have to eat. So I'm going to go through your apartment looking for anything useful to take with me, okay?
  - MPHHHHHHHHHHHH! - The blonde replied again, unable to utter any intelligible words behind her great gag.
  - Sorry honey. I can't understand you, and time is running out.
Having said that, she got up from her victim's thighs, and began to search around the entire house, leaving Mary desperately screaming from under her panties and the seven wraps of duct tape.
Mary couldn't believe how naive she had been, and how stupid she was trusting a common thief. Her confidence had left her tightly bound and gagged, with no remote chance of scaping. She struggled against her restraints as much as she could, but her movements were totally restricted by the action of the ropes, which in turn held her body against the chair.
After a while, the masked woman came back, with a smile that could be read in her eyes.

   - The truth is that it has taken me less time to ransack your house than your bosses'.

   - She said laughing.

   - MPHHHHHHHHH! -Came again her captive's replica.

   - Now I'm sorry to tell you that I have to go, baby. I have an appointment. But maybe I'll pay you another visit one day. - She added, winking. - When have managed to replace everything I have taken from you, of course.

   - MPHHHHHHHHHHHHHHHH! - Mary was crying, and had added a tone of despair to her muffled screams. She knew that she could not free herself from her bonds, and that the help of any neighbor was practically impossible, since her building was almost deserted. As if reading her mind, the intruder added:

   - Don't worry honey. When my date is over, I'll call the police to tell them you're here. - Mary sighed, relieved. - Well, if I remember. - She added laughing, and causing a new cry from her captive.

   - see you next time, baby. It's been a pleasure, like always.

Before leaving, she gave her a kiss through her mask and Mary's gag. Then she disappeared through the door. Mary began to fight uselessly against her bonds again. The thief had fixed them tightly, as much as she had sincerely wished. She tried to scream, knowing that it would also be useless. After an hour of struggling, she was exhausted, so she chose to relax, and try to see the positive side of the matter. She was tightly bound and gagged, fulfilling one of her deepest fantasies, and would possibly be released by the police in a couple of hours.

Possibly.

So she decided to let go, and began to turn and rub her body against the ropes that bound her, enjoying the friction they generated, until she fell asleep.

She was awakened by a knock from the door. A strong female voice echoed across the threshold as knuckles tapped the wooden surface.

   - Police! Miss Ruíz, are you in there?

   - MPHHHHHHHHHH! - The young woman screamed as loud as she could.

A few seconds passed before the policewoman's voice was heard again.
  - It seems there is no one. - She claimed. Mary began to exhale in panic at the sight of her staying there forever. However, an angel suddenly appeared. - Still, I think we should go inside.
Mary sighed in relief as she listened to the police pick the lock. But something was wrong. Instead of breaking down the door, they seemed to have the keys for the lock.
At last the door opened, and a figure stepped inside. She was dressed totally in black and had her face covered by a balaclava, and a scarf over it. Mary recognized her at once.
It was the thief!
  - MPHHHHHHHHHHHHHHH! - She screamed again, crying at her current situation.
  - Did you really believe I was the police? - The thief mocked. Mary nodded, embarrassed, which made her captor's mockery even louder. - As if I was going to let those cops let you go, and keep me from such sweetness. Besides, you have my DNA in your mouth. - She added while winking.
Poor Mary couldn't believe her bad luck. Not only had she been kidnapped, bound, and gagged by a sensual thief, but now she had to endure her mocks as well. It was simply not fair.
  - And now get ready, baby. We have a long and fun night ahead of us. And who knows, maybe this robbery eventually turns into a kidnapping.
  - MPHHHHH!
  - Oh, come on! Don'tt be like that. I assure you that if that happens it will be because you beg me to kidnap you ... although you will do it with your eyes, of course.
Again, she began to laugh, as she inserted the index and middle fingers of her gloved hand inside the blonde's culottes, laying the groundwork for an orgasm. Forgetting the word "kidnapping," Mary begged that this time he would let her finish.
It was indeed going to be a very long night.
