She bought a new toy from the pet store

 One day, my slave came home with a huge dog collar--something that could only be for a mastiff or St. Bernard.  It looks like a leather paddle with a leash that ends in a belt buckle.  Kind of strange, but as an implement to use on her ass, it looked promising.  

Last weekend, on Saturday, I didn't feel good in the  morning.  I didn't think we'd get any play in, honestly, but by around noon, I was feeling better. I told her to follow me into the bedroom.  

Once she washed herself, I had her get implements, being  sure she included that huge dog collar. She put on red and black lingerie with no panties.  As she crawled over to me on the bed, I played with her tits for a little bit, then I said, "Bring me that pussy."

She laid over me, bringing the pussy into reach.  I grabbed hold of her hair.  "What are you?"

"Your dirty fucking slut."

"Are you  plaything, whore?"

"Yes."

I grabbed hold of the dog collar and used the portion with the holes as a paddle.  "That stings," she gasped.  

"Good.  You ready for a beating, little slut?"

"Yes, Master.  Thank you, Master."

I began slapping her ass with it, 3-5 hits on each ass cheek, then alternating, again and again.  She moaned  in pain.  "You like that, whore?"

"Yes."

"Let's see how much you like it," I said, then slid a finger into her wet slit, sliding from her hole to her clit, using her own juices to lubricate it as I rubbed it.  She began gyrating a little and her breathing quickened as a rubbed rapidly.  She loves it when I'm rough with it.  

After several minutes, she pleaded, "Can I cum, Master?  Please can I cum"

"Beg me!"

"Please may I cum?  Please please please oh please..."

"No," I said, then grabbed hold of her vulva and pinched.  

"Oooooh..owww."

"Do you like it when I abuse your pussy?"

"Yes."

"Do you love it?" I said, as I pulled on her flesh.

"Yes!"

"Say it!"

"I love it when you abuse my pussy.   Thank you, Master."

I began to punch it.  She loves it when I punch her pussy.  Her wetness grew.  I could hear it squelching every time my fist connected with it.  I started playing with her slit.  "Can you hear how wet you are?"

"Yes.."

"That's my dirty fucking slut," I said. "That's my little fucktoy."

I went back to slapping her ass with part of the dog collar.  Her ass was getting very red.  She was reacting to the pain even more.  

After several fresh hits with this new implement, I went back to playing with her clit.  After a bit, she begged, "Can I cum, Master?  Please can I cum?  Please!"

"No."  I went back to abusing her pussy, pinching, pulling, hitting...then I slid four fingers into her pussy and fucked it.  She gushed a bit.  She was really enjoying this treatment, and the fact that she was getting sore helped.  She loved having her sore pussy penetrated.

I went back to playing with her clit.  It wasn't long before she said again, "May I cum?"

"Beg me, whore!" 

"Please, Master, may I cum?  Please!  Pleeeease oh please..."

"Cum for me, you fucking slut."

Her orgasm was intense.  I kept rubbing that clit.  I wasn't stopping at one orgasm.  She asked again, "Can I cum?"

"Cum for me."

She came again, her wetness flowing from her pussy.  "Master, I'm weak," she said,  Her safe word.  Unusual for her to stop after two, but it took a lot out of her after the edging, plus she had been tired all morning.  

"I want to see how this thing does when I use the length of it," I growled,  holding it out to her.  "Are you ready to try that?"

"Yes."  She got into position, ass toward me, head toward the center of the bed.  

I whipped her with the collar, connecting with a loud slap and her lovely, red ass.  "Ooooo, that stings!" 

"Stick that fucking pussy out."  

She adjusted so her vulva was fully visible.  I whipped her across that ass, and it connected with both cheeks and her pussy.  

"Oooowwww..."  She withdrew her pussy slightly. 

"Stick it out, whore."  She did.  I whipped her with it again.  And again.  And again.  I'm not sure how many times I hit her that way, but it wasn't many before she said, "Master, I'm weak."

"Are you ready to get fucked, little whore? "

"Yes, Master."  

I wrapped this implement around her neck and mounted her, shoving my hard cock into her wet cunt savagely.  "Oooo my pussy.  It huuuurts," she moaned.  

"You love it when it hurts, don't you, slut?"

"Yes."

"Tell me you love it."

"I love it when my fuck my sore pussy..."

I fucked her hard, using the implement to choke her.  She got wetter.  I smacked her head a few times.  She struggled, which turned me on even more and made me grow savage with my thrusts.  "Take it you fucking slut.  Take it!"  

I then pinned both of her arms above her head and slapped her head every few thrusts.  "You're just getting wetter, fucktoy.  You love that fucking violence, don't you?"

"Yeeessss" she cried.  

I kept fucking her , degrading her as I thrust, pulling her hair, smacking her, cutting off her breath with my hand over her mouth and nose, choking her with the dog collar.  Eventually, I said, "I'm going to cum."  With a final balls-slapping thrust, I shot my load inside of her.  

I rolled off of her and said, "I love you."

"I love you too," she said breathlessly.  I rubbed her tits other parts of her as I lay there with her.  

The next day, I was pretty horny early in the day.  I went back to the bathroom.  After I was done washing off, I texted her: "Come here."

She was on the phone and told me she had to say goodbye and she would be there.  I laid there on the bed, naked, waiting for her.  

She came in and sat down on the bed by my feet.

"Do you know why you're in here?" I asked.

"To serve you," she said quietly.

"That is great answer, and the correct one."

She began rubbing my cock, then grabbed it and began stroking.  I pushed her face down against my abdomen, cutting off her breath.  I let her up after a bit and pushed her down again.  And again.  And again.  She never stopped stroking.  I let her up and said, "I love that my pleasure takes priority over your need for oxygen, whore.  You're a good little slave."  I pushed her down again and cut off her breath.  

After the breath play, I asked her, "Do you want that cock in your mouth?"

"Yes, Master.  May I please suck your cock?"

"Of course you can pleasure my cock with your mouth, whore."  I guided her head down to my cock, holding her by the hair, pushing her all the way down my shaft with my hand on the back of her head.  After a bit, I draped my leg across her upper back and used it to thrust her down over and over.  She loves that.  She loves it when she struggles to breathe while going down on me.  

I came down her throat and let her up for air.  "I love you."

"I love you, too." 

We talked for awhile.  She said at one point, "I want to try that collar again.  It stung a lot, but I feel like I could get used to it."  

"Oh, we'll definitely use that again," I said with a grin. 

On safe words: can you just say "No?"

 The answer?  Of course you can, but because of the many ways members of the BDSM community play, it becomes necessary in many circumstances to use other words or even actions to stop play when someone is uncomfortable with what is happening in a scene.  

   Recently, my slave did a post on our Facebook page, asking what people used as safe words.  A person who claimed to have left the page (and I have no reason to doubt it) called most of the answers "toxic" and made clear that they did not understand the many nuances of BDSM.  Before this same person claims that I'm gaslighting here: they did not ask any questions or run through any hypotheticals that might make them draw less nefarious conclusions about the safe words used.  

    I did find it alarming that one person said that they didn't use safe words at all and did not want to stop play for any reason.  There can ALWAYS be a reason--I have had a medical reason to stop play, and believe me, that can happen to anybody.  

   But yes, "No" can be all you need, depending on the way you play.  But as my slave mentioned, her safe phrase is "Master, I'm weak."  The person thinking that it's a toxic thing to have her say probably thinks it's some sort of mind fuck, and I understand that perspective.  However, my partner is into humiliation; she finds this safe phrase absolutely hot.  She knows  she's not a weak person.  In fact, nearly every partner I  have chosen to be with was a strong, independent woman who was very selective about who dominated them, and often dominated other men and/or women.  The ones who were purely submissive sexually were also strong women.  Hey, I have a type.  I love a challenge.  

    Another reason "no" doesn't work for my slave is that she is into consensual non-consent.  "No" is part of that type of play.  "No, stop, please don't."  It's hot for her and for me.  

    Remember, this is all about consent.  No means no, but "no" can be different words if that's what we agree to use.  

    Previously, I mentioned actions.  We engaged in play where she's not going to be able to speak--breath play, tape gags, mouth fucking, etc.  She can't always say her safe phrase.  In our contract (and you do NOT need a contract; many submissives do like clearly defined rules, though, so it's something to consider), it says for her to tap three times OR make three noises in rapid succession: "Mmm mmm mmm."  Either way, I know to stop.  

     Also, remember that with experience, a good Dominant knows how to read expressions, listen for changes in breathing, and take all kinds of physical cues that let them know that a submissive is in distress.  After 28 years in the lifestyle, I have become very good at learning the subtleties--and overt signs, of course--that mean my partner is in distress.  However, nobody is perfect, and people get carried away.   Safe words are a must!

    People can use all different safe words.  It doesn't matter which words you use.  It does matter that you clearly agree on them and that play absolutely stops when they are uttered, or if the actions or noises you agreed to make are taken or uttered.  And play can stop for ANY REASON.  It doesn't matter what it is.  If you don't stop play, you are committing the crime of sexual assault.
