Mis-behaing Twins

My grandson Chase went through his early stages of puberty pretty easily, and now his hormones  were raging while his twin sister Chelsea's were just beginning to hit her.  Her young breasts  were swollen but not yet to that perky stage.

 Chelsea and  Chase used to fight like cats and dogs, but once the two of them hit this stage of puberty they seemed to have taken a special liking towards each other.  He takes her with him on errands and helps her whenever she asks.  I see casual touches between the two of them but write it off  as just teasing. 

For some reason I was thinking of the two of them while lying in bed last night, and I found myself getting wet with excitement.  My hand went to my nether region, to my lips,  stroking  them as my mind fantasized about their young bodies

What would it feel like to have his small cock in my mouth or to watch him suck her clit?  My secret thoughts and finally the mental image of him cumming in my mouth combined with my slick hand soon made me cum and I even squirted a  little.

Then suddenly I saw a flash of movement at my bedroom door.  At first I thought it was Chase, but then  realized it was the two of them.  Well, perhaps I can use this invasion of my privacy to my advantage.  If the two of them are that interested and curious perhaps I can be too.

After all,  their behavior while visiting me has been getting constantly worse.  I suppose it's because I never spanked or disciplined either of them.  I immediately put on my robe and confronted the two of them, and  told them I saw them watching me.   Both had their eyes down and  said nothing to me.  I told them both that they will be punished in a special way that may make them start to listen and obey me.  Then I sent them to their rooms for the night to think about what  the special punishment might be.

The next day is chore day and they seem to be doing ok.  They are probably afraid, as I had never threatened them before.  But this time I was determined to go through with my decision.  After all, I plan to get satisfaction out of this as well.  By mid - day both of them were starting to act up and not finish their chores.  Finally I'd had enough.

I called them both in to  my bedroom and told them to stand at the foot of the bed.  I went to the closet and grabbed one of my wider looking belts and laid it across my shoulder.  Resisting a smile, I turned to them and spoke to them both in the sternest voice I could muster.

"Both of you have disrespected me and violated the privacy rule of  my house and I'm tired of it.  So right now you are both going to start getting punishments for not minding me."

They looked at each other and both turned and put their hands on the bed with their  asses sticking out at me waiting.

"OH NO!  I shouted at them," This is different!   The two of you decided it was okay for you to watch me in a private moment, so now I get to watch the two of you.  It shouldn�t be hard to do, as I suppose the two of you have already watched each other anyway.

�NO, Grandma.  We never did any such thing,�Chase said, looking at me with pleading eyes.

"Grandma, what are you saying?" Chelsea piped in.

"I'm saying I'm not dumb, I   know the two of you sleep together at night by sneaking into the other's room. 

"I'm saying I'm giving you a choice.  Either submit to the same embarrassment as you put me through, or take 10 lashes with the belt AND I tell your folks what you  get up to out here."

"Chase, you're going to get to go first!  You already have your shirt off from mowing the grass, so just stand there and let your sister take off your pants."

"WHAT?!" he exclaimed.

"You heard me, you two saw me naked last night.  I told you both your punishment was going to be different didn't I?  Just shut up and get it done."

 Chelsea looked at her brother "Chase, I'm real sorry."

"Just get it over with sis."

Chase turned s toward his sister. I took  my hands and pushed her to her knees in front of him and watched   her undo his jeans and lower the zipper directly in front of her face.  I watched as she helped him step out of his pants leaving him wearing just his shorts.  I  saw her looking at the shape of his cock in his shorts as I told  her to continue.  Her hands gripped both sides of his shorts, and as she lowered them I noticed her eyes have not strayed from his. I looked at her, and saw  that her eyes  were  looking at his body.  I wondered when it was the last time she actually saw him totally naked.

His youthful body  was already becoming muscular from all the work he does, plus at 15 his hormones  were already building muscle.  His cock  wasn't hard, as he  was still shy from all  that was happening but I see it's  a good size for a teen and he had a light bush surrounded e it. 

I wanted it so bad.

As I stood next to them,  unbuttoned my blouse and took it off.

They both stared at me. �What!" I said,  "you both saw more than this last night.  Maybe if we get this out in the open it won't be such a big deal. I'm half naked already. Chelsea, what's with you?  I want you like this as well.  And don't tell me you have never done it!"

"Grandma?� not in front of him!"

"Chelsea, do you know what to do to excite him?"

"Of course not Grandma!"

�Chelsea, get him hard for us�         

�Grandma! please.�

�Take off your blouse.  NOW!�

She hesitated just a split second to long.

I reached over with two hands and ripped her blouse open, buttons flew everywhere. I pulled  it off her shoulders and threw it to the floor.  NO bra!  No wonder she was hesitant to take her blouse off.

She brought her hands up to cover herself.

Kneeling next to her, I reached over and took Chase's cock in my hand and begin to stroke it.  When it became  about half hard I took her hand and guided it  to him, wrapping her little cool fingers around  his shaft.  I placed my hand over hers and showed  her how to stroke him.

This  wasn't proceeding fast enough for me so I decided to speed things up a bit.  I figured he wouldn't be able to take much of this, and as I heard his excitement and felt  him trying to thrust more back at us.

"Slide  your hand up and down as you would if you were riding him."

Then I instructed her to continue to stroke him faster and not to stop until I told her to. 

Walking behind him, I whispered in his ear. �Do you want to fuck me?  Maybe you want me to suck your cock." 

"NO," he replied.

"Then I know what you want.  You want to fuck your sister don't you?"

Suddenly he moans and yelled out. "Oh my god sis, don't stop.  Don't you dare stop." 

We both watched as his small but mature cock erupted and cum landed on her hand, coating it, and providing yet more lubrication as she continued to stroke him just as she had been told.

She seemed to be enjoying this as her actions become more deliberate and her hands slid over the top of his cock causing him to jerk away from her.

She looked at me. "I didn't mean to hurt him!  I'm sorry Chase!"

"It's okay Chelsea  you didn't hurt him.  A guy is very sensitive after that happens and the fact that it, did meant you excited him very much."

I handed her a towel and watched as she cleaned herself and handed it to him.

"Chase, How was that?" I asked. "Is it what you thought it would be like with your sister?"

"Oh yeah," he replied, "even more exciting than when I think about her doing it at night."

Now it�s time for both od them  to tell me   some secrets. 

"Chase,  you think about me at night when you are doing it to yourself?" Chelsea asked.

"Hell yeah sis, you're one hot looking girl and I do love you."

I looked at her face and her exposed chest and  saw the familiar reddening that tells when a girl is excited.

"Chase, I think we've waited long enough.  Okay  Chelsea, it's your turn to get undressed."

"But grandma, I'm a girl."

"So what"?

"He'll see me naked.  You'll see me naked as well."

"That's part of the punishment and getting you used to this, as not something strange, but as something exciting ."

"Chelsea, drop your pants,  but leave your the panties on.

 Chase and I stood  there and stared at Chelsea's beautiful, perfectly shaped breasts.   I thought that the power of recovery was wasted on the young as I looked and saw his cock begin to swell. 

  Chelsea stood there in just her panties, and as I stared at the junction of  her  thighs I saw a wet spot forming  in the cotton gusset of her panties.  My mind works.....

"TAKE THEM OFF!" I ordered.

When she  didn't respond, I went behind  her and wrapped my arms around  her and held her.

"Chase, as she won't do it then you take them off for her!"

He didn't hesitate, he dropped to his knees, grabbed s  her  panties and pulled them to  her feet.   He stood there staring at his sister's sex as I  took my leg and kicked  her foot to open her legs wider.  I did it more for him than me.

"Tell me what she looks like Chase!"

"Oh damn, she's perfect.  She has just a few hairs beginning to come out and the lips are all red and puffy.  It looks like they are wet too."

"Chase, that's because she got exciting getting you off."

"Chelsea, now it's Chase's turn to use his fingers on you."

"No! please, don't make me,   this is bad enough. Please, I'll mind you in future."

"Sothe humiliation is more than you can take?  Does it make you feel bad or embarrassed or humiliated to do things in front of me and your brother?"

"Oh God yes! I feel so funny about being naked in front of the two of you.  God I feel so embarrassed."

"Well, then perhaps you just named your punishment. If I don't have Chase touch you, then will you accept another form of punishment that doesn't involve beating or pain?"

"YES!"

"But Chase has to still watch . . . that's part of it your punisjment."

"YES"

I got on the bed and leant back  against the headboard with my legs spread.

"Chelsea, come up here between my legs and lean back against me and spread your legs out so they are laying alongside mine."

I watched intently as  she climbed on the bed, her firm young breasts not even  jiggling as they were still so small.

"Chase, you get on your knees and kneel between her legs as close to her as you can get so you can watch what she has to do."

As he approached, we could  both see his cock had gone from soft to rock hard, sticking out towards  us .  By the time he got  between Chelsea's legs, he's a foot from her pouting lips.

I took her hands in mine and run them over  her breasts.

"Chelsea, is this what you do when you are in the shower?"

"Yesss."

"Do you pinch the nipples like this?"

"Watch Chase, see how they get hard just like mine do."

I  took one of her hands and pressed it downward towards her pussy.

"Please, don't make me," Chelsea pleaded.  "I've never done anything like this before."

"But you agreed!"

Her hand become less resistive to my guidance."

"Once we reach your pussy lips I'll guide your finger between them getting it wet with your juice." 

Chase watched as  his sister's finger disappears between  her wet lips.  Then I  moved it up and slid it over  her clit.  I felt her shake with these new feelings.

"Chelsea, touch yourself, touch your clit and make yourself cum while Chase and I watch you."

She continued to stroke herself probing until she found just the right area to give herself the right feelings.  She begin to squirm in my arms and suddenly she stopped.

"Why did you stop?" I asked.

"I had to," she replied  "It was feeling . . . I don't know . . .like something was going to happen."

I reached down between her legs and, dipping my finger inside her I continued where she had left off.  My fingers went to her clit and began the stroking that she needed to cum.

"Please stop! please don't."  But knowing what was about to happen, the excitement of being the first to make her cum, was  too much; there was no way I  was  able to stop even if I wanted to.

Her little hands grabbed mine and  tried to pull them away; but  she was not strong enough.  Plus Chase is there to help;  he took both of her hands and held  them so she was  now helpless to stop me.

Her little clit had grown to a nice nub and  was easy prey for my wet and rapid fingers. 

"Grandma!" 

"Let it happen Honey.  Just let it go and you will experience something even better than your brother did."

Her little body begins to tighten up, and then all at once she shook and I felt  her stomach spasm as if she had a hard cock buried inside her.  Her legs clamped my handto keep it in place  so I couldn't take it away.

I keep it up until she begged me to stop telling me it's too sensitive.I finally succumbed to her wishes and removed my hand and let her lay back against me.

Meanwhile Chase has been busy stroking his own cock.  "Chase, why don't you save that for a little later son."

Eventually I feel Chelsea stir and she turned around to kiss me.

�Grandma, can we do this again?" she whispered.

"Yes honey, whenever the two of you are here."

"Can Chase and I sleep together?"

�We will all sleep together.�
