Vibrator and nipple clamps for Erica

I relax with my sister on the couch while we both recover. I start to check on my phone the photos I took of my sister when she pleased me, including one with her open mouth full of cum. I also send the pictures to my sister through the ultimate app message system, giving her material for her masturbation and edging sessions.

She also unlocks her phone once she hears my messages' notifications and starts looking at the photos. Especially the one with her mouth full of cum.

"You are so pretty in that photo," I told her while looking over his shoulder.

"Thank you..." She timidly answers with her flushed face. "I guess."

"Why so shy? Don't be embarrassed. This proves you can be a cumslut for me."

She keeps staring at the photo without answering me.

"Will you..." She tries to answer. "Will you... make me masturbate to these photos?"

"Of course. When you masturbate, I want you to look at the other photos of us that I have sent you."

"I look so slutty..."

I let her continue looking at the photos for a few minutes. Now is time to give her the gift I have prepared.

"I need your phone," I command her. "Tell me the unlock code. You remember you have no right to privacy, right?"

"I know." She says as she gives me her phone, showing me the pattern to unlock it without hesitation. "What will you do?"

"First, I will install software to control your phone, like the ones I made you install on your computer."

"No surprise." Perfect, she is starting to accept my control over her. "You want to know who I talk to and text." She knows very well that she can't disobey me, so she has nothing to hide from me.

"And another thing," I add. "A surprise."

Next, I install on her phone another software related to my gift. Once installed, I get up, go to my room and return with two things I bought for her.

"This is for you," I told her, showing her my two presents.

"And you want me to wear it?" She asks me once she notices my two gifts. What I have for her are a vibrator egg and nipple clamps with a chain.

I sit near her, and first, I put on the clamps. Once both are in their place around her nipples, I can't resist pulling a little on the chain, not enough to hurt her, but enough to stimulate her, making her release some cute whining and moaning.

Next, I make her open her legs with my hands, exposing her cunt. I pick the egg and insert it inside her. Usually, these vibrators are attached to a manual control with a cable, but this is a modern one controlled through a phone app that I had already installed on my phone and hers. But it also has attached a cable sticking out of her cunt, but instead of a manual control, it ends in a clamp. With the vibrator inside her, I show her the clamp.

"What will you do with this?"

"This is so you don't lose the vibrator. After all, you don't wear panties."

"But...but... where will you put it?"

I don't answer. Instead, I pick her clit. Once I grab it, she realizes that is where the clamp goes.

She closes her eyes when I click the clamp. Probably she thought it would hurt, but those clamps are small plastic ones. They are not like the metal ones. They do not exert too much pressure so that she can wear them over long periods. Once my sister realizes that it does not hurt and can endure it, she looks relieved.

"It shouldn't be doing something?"

"Wait a minute."

Now is time to show her how it works. I pick up my phone and open the app that controls it. This vibrator can be programmed to start and stop automatically and even change its intensity. It can also detect her arousal state, so I could use it remotely to put her on the edge of orgasm but stop before she can release. Still, before being able to do that, she must wear it and reach the edge herself so that the program can learn.

"Oh," she says once the vibrator starts moving. It is only at low intensity. Not even you can hear the sound.

"That's it?" She said after 15 seconds when the vibrator stopped.

"That's it. Just like that. Low intensity, with more we risk that you can't avoid cumming, and we don't that right?"

"Yeah, we don't want me to cum without your permission." She replies reply sarcastically. "How much should I wear it?"

"All day."

"What?"

"As you hear me. I want you to wear it 24x7. And the clamps too. I have programmed the vibrator to keep you constantly wet for me. I have prepared the program to turn on for 15-30 seconds and 30-60 seconds between activations. The random variance helps you not know when it will turn on."

"You want me to stay all day horny without orgasms?"

"You still can ask for permission every time you masturbate. If you are a good girl, maybe I allow you to have released from time to time."

I wait a few seconds, giving her time to realize her new situation, just in time for the vibrator to start again.

"Sis, " I continue once I see on her face that it has ended again. "What did I tell you that you are?"

"Your sex object."

"And don't you think a sex object is useless with a dry cunt?"

"Well, sure... but..."

"With this, you won't appear at my door again without being wet."

"I can masturbate before seeing you. You don't need me wet when I am not with you."

"It is better if you are always wet. Look at it as training from when you live with me. After all, you don't expect me to ask you permission whenever I want to use you."

"Of course not, 'my body my brother rules,'" My sister replies, quoting her mantra.

"Exactly, as I told you, I do not believe women should have a choice. I expect you to open your legs on command. But I don't want to hurt you because your cunt is dry, so you should always be in the mood to do it. Always wet and horny for me."

"Can you at least let me take them off while I sleep?"

"What can I gain from it?"

"Please..." She pleads with me. "I have an idea. You want me to be horny, so let me take off the clamps and vibrator to sleep, and in return, I will masturbate before going to sleep."

"Without orgasm."

"Of course, I won't even ask for one on those cases."

"One edge is not enough for the whole night with the vibrator doing its job."

"I will need to clean and recharge it."

"Don't worry. I can give you another pair if you want."

"Two edges?"

"Deal," I reply at the same time that I shook his hand.

"Thank you, brother. We have a deal". Perfect. I have made her willingly agree to her own denial.

"You can take off your clamps and vibrator while you sleep with the condition that you masturbate twice before that. That won't count as the five you are already required every day. You are not allowed to cum nor ask for an orgasm those two times."

I can see in her face that she was thinking of the possibility of combining those two edges with her required number of masturbation. Sorry, no loophole this time.

After that, I made her stand up. I pick her leash, which made her immediately put her arms on her back. After that, I unclick the leash from her collar to test it clicked on her nipple chain. I made her follow me, taking a couple of laps around the couch. Every time I pull the leash, she feels it on her nipples. Enough to make her moan but not too strong to hurt her.

When I have enough, I stop and unclick the leash again. This time I kneel in front of Erica, checking her cunt. The vibrator cable comes out of her cunt, ending in the clamp attached to her clit. There is a small metal ring at the point where the clamp connects to the cable.

I can not resist clicking the leash on her clit clamp. I made her walk again, this time with the leash attached to her clit. Her moans are louder now than before with her nipples.

"I like this," I told my sister. "Next time when you come home. You should be leashed before I open the door..."

"You want me to have the leash on my clit like this." She interrupts me.

"Yes, exactly."

"Fine, I'll do that. Not that I have any choice."

After finishing with her leash, I return to my bedroom to pick up the other three vibrators and nipple chains. I return with Erica. Once she sees the toys, she looks surprised.

"Those are too many. You won't expect me to wear all of it?"

"No, sis. I want you to use it, but not on you."

"What do you mean?"

"I want you to order my girls to wear the same as you, including these toys."

"Why...why don't you give them the order yourself?"

"You are their mistress, and I expect you to show them some authority."
