It becomes to much.

Alex kept moving the vibrator back and forth between them. One edge for Sarah and one orgasm for Alex. Sarah tried to hide when she was reaching the edge, but Alex was too vigilant, catching Sarah each time and giving her a few slaps. The frustration in Sarah had built and built in the last few days and was now boiling over. The last time Alex denied her, it became too much, and a couple of things happened. Sarah started air-humping, tears formed in her eyes, and she let out a loud animalistic sound that Alex had never heard from someone before. Alex looked down concerned, and finally Sarah muttered the words.

"Applejack!" Alex stopped the vibrator and untied Sarah quickly. She was shaking uncontrollably, and tears were streaming down her face. When the bonds finally were untied, she didn't know where to go. The feeling inside of her was one she had never experienced before. It was one of immense pleasure but also uncontrollable frustration. The sensations were so intense she had never felt before. Half of her wanted to masturbate furiously, while the other half wanted to feel like this longer. Sarah's mind was reeling and thinking a thousand miles an hour until she felt the embrace from Alex. This pulled her back to the world.

"Hey, how is it?" One could hear the worry in Alex's voice. Sarah was still shaking, but she grasped Alex's arm for mental support.

"Hey, I'm here for you if you want." I took a few seconds for Sarah to put words to her feelings.

"I'm just overwhelmed. That was really intense." The frenzy inside her had started to mellow out. The shakes were lessening, and she felt guilty and weak for saying the safeword.

"I'm sorry, miss Alex, for saying the safeword." Alex smiled at her proudly.

"Don't say that. You used it exactly as you should. When it became too much, and please don't call me that. I'm your bestie right now, not some domme." She whipped the tears from Sarah's cheek.

"So I didn't hurt you?" Alex was really worried that she might have harmed Sarah in some way. But Sarah shook her head.

"No, it was just so intense I needed a break. I've never felt like that before." Alex examined her face intensely before accepting Sarah's answer. But she still thought Sarah might need a minute to land before touching the subject again, so she stood up and asked.

"I'm getting something to drink to cool down. That was really hot and intense for me as well. What should I get you?" Sarah looked up.

"I'll have whatever you're having." Alex nodded her head.

"Ice-cold water it is, then." She said and walked out of the room.

As soon as Alex left the room, a feeling of abandonment washed over Sarah. Had she done good, Alex had said she was proud of Sarah for using her safeword, but they had to stop because she had been weak. Being unable to take the teasing, being a greedy, horny slut. Her thoughts spiraled from there, and she started to punish herself like Miss Alex had done with pussy slaps and nipple tugging. When Alex returned, she was surprised to see Sarah wasn't lounging on the bed but going at it.

"What are you doing?" She asked, confused. Sarah slid onto the floor and hugged Alex legs.

"I'm sorry, Miss Alex, for disappointing you. I will be a better slut, so I started punishing myself." Alex was baffled by what Sarah said. She thought Sarah would be relaxing, and they could talk about what happened. But Sarah had slid into the role again of submissive, Alex suddenly realized her mistake. They hadn't had any aftercare and properly ended the session. Now she thought they would continue. Alex kneeled on the floor, put down the glasses of water and took Sarah's face in her hand.

"Sarah stop!" Sarah looked confused and a little hurt. Alex stroked Sarah's cheek with her finger.

"The session is over, and we can just be friends. You were so amazing, but now we both need to unwind and reset ourselves." Sarah eyes started to well up with more tears.

"I'm sorry, I keep getting it wrong and being a dum horny slut." Alex interrupted her by kissing Sarahon the lips.

"Stop saying that. I had so much fun, but I don't want to talk to you about it on the floor. Let's get to bed, and I want to hear all about what a horny slut you were." This pulled an embraced smile from Sarah, and they got up. Alex handed Sarah one of the glasses with ice-cold water, and they sat on the edge of the bed and talked.
