New Characters:
Tom and Nancy – parents of the twins
John – infant boy
Carrie – infant girl
When Julie turned 12 she started to do some babysitting.  That gave her some spending money and made her feel good about herself.  All the parents she sat for really seemed to like her and would recommend her to other families in the immediate area.  About a quarter mile down the road a new family moved in.  Mom, Julie and I went down to welcome them to the neighborhood.  We learned that Nancy and her husband, Tom, had two infant twins, a boy named John and a girl named Carrie.  They were toddlers 14 months old and as cute as could be.  Nancy asked mom about any babysitters she could recommend.  Mom told her that both Julie and I were available and if Nancy would feel more comfortable we could baby-sit them at our house until the twins were a little older.  Nancy thought that was a great idea.  Mom mentioned that there was another little girl, named Susan, which could fill in for one of us if there were a schedule conflict.  She said Susan spent most of her free time at our house anyway.  
It was the beginning of summer vacation for us so we were available right away to start sitting.  The first two weeks the twins came to our house until both mom and Nancy were confident that we could take care of the twins and could handle changing the diapers.  After the first few times we mastered the task.
Finally, some months later, we were allowed to stay alone at Nancy and Tom’s house to care for Carrie and John.  The first afternoon we were alone Julie wanted to see of the twins would nurse on her nipples.  We sat on the couch.  Julie removed her top and training bra and offered a nipple to John.  He immediately snuggled in to Julie and started to suck.  Of course nothing was coming out so it was just like a pacifier.  I brought Carrie over to the couch and positioned her so she could nurse on Julie’s other nipple.  Both twins seemed to be content and Julie said it was so neat and felt really good.  She thought that Susan would want to try this too.  I sat down next to them and just watched for a while enjoying the sight.  
Julie suggested;  "Why don't you loosen Carries diaper and massage her little pussy."
I only thought about that for a minute before I had her diaper undone and had my finger on her little slit.  I very gently moved my finger in a circular motion.  I didn’t want to rub inside, as I didn’t want to make her sore.  She felt nice and didn’t seem to mind what I was doing at all.  She even spread her legs a little as an indication to me that she liked what I was doing.  
I noticed that Julie had taken her hand and slipped it into John’s diaper and appeared to be holding his little penis.  We probably continued this way for half an hour, maybe more, before both the twins were asleep.  We carried them into their nursery and put them into their cribs.  We watched them sleep for a little while when Julie turned to me and undid my pants.  She removed her shorts and panties.  
She said;  "I'm more than ready and needed you to fuck me."  
So right there on the nursery floor we made love.  I took my position between her legs.  I love the sight of her pussy spread open and waiting.  I bent down and started kissing her mons.  I moved to the hollow junction where her legs attached.  I kissed first one side, then the other. I could tell she was impatient and wanted more.  I placed my mouth over her whole pussy and set my tongue to working.  I knew it was time as the ache in my dick was growing.  I lined up and with one smooth stroke was buried deep inside her.     I started pumping in and out increasing the speed.  I could feel the tightening in my balls.  We were both so excited and it didn’t take long before she had her orgasm and I emptied my load in her.  I pushed as deep as I could feeling every pulse of sperm as it flooded her.  Once spent we cuddled on the floor for a while enjoying the afterglow.
 
Julie said she wanted to try something.  I just watched as she slipped two fingers into her vagina to collect some of my cum.  She then took her fingers and pushed it into Carries mouth transferring my sperm.  In her sleep Carrie sucked Julie's finger and actually swallowed my cum.  Julie did the same for John.  
Julie said:  “The twins didn’t object and hungrily sucked my finger.  I wonder what their reaction would be when they’re awake.  We will have to try that another day.  I’ll suck you off and with a kiss give some to each of them.  That will be so hot!”  
I told her:  “I don’t think that’s such a good idea.  We’ll get in trouble.”  
She said:  “Don’t be silly.  No one will ever know.  If the twins don’t like the taste they will just refuse it after the first time.  I want to try.  Who knows, they may even nurse on your dick.  That would be so hot to watch.” 
We got dressed and went into the living room and watched TV until Nancy came home.  She asked how the day went and we told her that everything went perfectly.  Nancy gave us a hug and thanked us for being her savior by taking care of her little bundles.  We told her that we would be there first thing in the morning.  
The next day Julie insisted that we see what the twin’s reaction to my sperm would be.  John and Carrie were playing on the living room floor.  Julie brought them over, opened my pants, and took my dick out.  She jacked it a few time and then took Carrie’s little hand and wrapped her fingers around my shaft and had her help to jack me off.  John reached over like he wanted to help.  I sat there and watched as the three of them played with my dick.  It was quite a sight.  I was real hard and getting close.  
I told Julie; "Get ready."  
So she moved the twin’s hands and took my dick into her mouth just in time as I started to squirt cum.  I deposited spurt after spurt into her mouth.  Just like she planned she didn’t swallow.  When I was spent she removed her mouth and opened to show me how much was there.  She took Carrie first to give her a kiss.  They kissed and Julie forced some into her little mouth.  Carrie had a surprised look on her face, as she tasted what was now in her mouth.  Finally, she swallowed and reached for Julie like she wanted more.  Julie then turned to John and did the same.  He took longer to make his decision, but the result was the same.  Both of them liked my sperm and acted like they wanted more.  
Julie said:  “See!  I told you they would like it.  They want more.  You’ll have to give them more.  I think they will want it direct from the source rather than getting it from my mouth.”  
I told her; "I don’t think we should be doing this with them."
All she said was;  "Don't worry nobody will find out.  They seem to like it so no problem."
I said;  "What if Nancy finds out."
She answered; "How?  There was no way she will ever know.  The twins can't talk."
So just before we gave them their lunch, Julie had me remove my pants and sit back on the couch.  She set Carrie next to me with her head in my lap.  She took my penis and offered it to Carrie rubbing the head against her lips.  She opened her mouth and the head of my dick slipped into her mouth.  She immediately started to suck.  Satisfied with the way Carrie was nursing on me, Julie sat back to watch and helped by gently jacking my dick.  She offered a nipple to John and he immediately started to suckle too.  I had to admit it was exciting watching them both and feeling Carrie’s little mouth and tongue on my dick head.  There was more that just suction.  The movement of her tongue on my dick head was so different than when Julie or Susan would take me in their mouths.  As I was getting closer I reached down and together with Julie we stroked my shaft.  The combination of Carrie's mouth and our hand action I was getting me much closer.  I could feel the deep stirring in my balls.  
I whispered to Julie; "I'm ready to cum."
Julie bent down by Carrie's ear and quietly said:  “Carrie honey, get ready your treat is going to come in your mouth real soon.  Suck and swallow it all like a good little girl.  It will taste really good.  Remember, I gave you some before and you liked it.  You will get more this time.  It is all for you.”  
Two more strokes on my shaft and the first spurt entered Carries sucking mouth.  She didn’t flinch but just swallowed and continued to suck and suck and suck.  It seemed to me like I shot more than I had ever had before.  When I was done Carrie just held my dick head in her mouth and every so often she would give a little suck.   Finally, I picked her up and gave her a hug.  I told her what a good little girl she was.  She smiled a big grin at me.  I gave her a kiss and slipped my tongue into her mouth and could taste residue of my sperm.  I gave her another hug and kissed her forehead.  She gave me a big hug back.  We sat for a few minutes and watched as John continued to suck Julie’s nipple.  
Julie announced to the twins:  “OK, you two munchkins it is now time for lunch.”  
Into the kitchen we went.  I held both of them while Julie heated their food.  I fed John and Julie fed Carrie.  They were both good eaters and didn't make a fuss.  
After they had finished eating Julie said:  “It’s time for dessert.  Everyone back in the living room.  This time John was placed with his head in my lap the same as before with Carrie.  Next, Julie offered my dickhead to John.  She rubbed it against his lips until he opened his mouth and started to suck.  It took longer this time for my excitement to mount.  It was apparent that the twins were ready for their nap.  John closed his eyes and seemed to suckle slower.  In an attempt to speed things up Carrie began to pump my shaft faster and faster.  Again, I could feel the stirring in my balls.  I nodded to Carrie so that she would know that I was really close.  I finally came in John’s mouth.  He sucked and swallowed every drop.  He seemed to like it as much as Carrie did.  But because he was tired he didn't show the same level of emotion.  As my dick started to deflate he continued to suck and before long he just held me in his mouth.  The next thing I knew he had fallen asleep.  He looked like a little angel.  .  
I looked over at Julie and Carrie too had fallen asleep in Julie’s arms.  It was quite a sight.  Julie told me:  “It isn’t quite fare.  You came twice and I sit here frustrated and ready to go.  You will have to use your mouth and suck me off.  I need to cum real bad.”  
With that we put the twins to bed and I proceeded to do my duty.  Julie naked was a vision of loveleness.  She laid down with her legs spread wide and here outstretched arms invited me to join her.  I took my position between her legs.  With my thumbs I spread her pussy lips open and inhaled  deeply.  Her excitement produced the most intoxicating aroma.  Next, I stuck my tongue out and gave one broad lick from her butt hole all the way up to her clit.  As I did this I could feel her shake.  The taste was delicious.  I knew that it wouldn't be long before she orgasmed.  I poked my tongue into her hold in search of more of her nectar.  I was rewarded with a generous helping of her juice.  I then decided to concentrate on her clit.  I gently blew on that little pearl peeking out from it's protective hood.  Finally, I enclosed her clit with my lips and flicked my tongue back and forth.  That pushed her over the edge and she started to shake.  I just had time to cover her whole pussy with my mouth before her legs slammed shut on my head.  I was in a vise trapped until she was ready to release me.  I was treated to a large gush of her juice.  When she finally calmed down she said that was one of the best and an earth shattering climax.  
We cuddled for a while as she basked in the afterglow of her orgasm.  We agreed that we had quite a day.  Later, Nancy came home and we reported that the twins were asleep.  They were good all day and ate a big lunch.  Julie and I looked at each other and just smiled.
When we got home Susan came over to play with us.  Mom invited her to stay for dinner.  She called home and her mom said it would be OK.  We went outside to play until dinner was ready.  Once out of earshot Julie told Susan about our day.  Susan couldn’t believe that they both sucked my dick.  I confirmed Julie’s story and said that we’d be doing that again everyday.  Julie then said that in the morning she would tell our mom that she didn’t feel good.  That way Susan would sub for her and she could see for herself.  Susan looked around to make sure no one could see and then gave Julie a big thank you kiss.  I could see their tongues dancing in each other mouths.
The next day, mom called Nancy with the news that Julie didn’t feel well.  She thought that it would be best not to expose the twins just in case it was more than just a tummy ache.  She told Nancy she would call and have Susan sub for her.  Nancy was pleased and thanked her for everything.   I was there before Susan and was playing with the twins as she arrived.  Nancy thanked Susan for coming and told her to make herself at home.  Before she went out the door she gave the twins a kiss and told them to be good.  
When we were alone Susan gave me a hug and a kiss and told me that she missed me.  I told her that I missed her too.  We played with the twins for a while before Susan said she wanted some sexual activity.  We checked and changed each of their diapers before returning to the living room.  Susan had us spread a blanket over the couch as protection before we both got naked.  She had me sit back on the couch, got between my legs and sucked me to get me hard.  She then straddled my lap and slid my dick into her vagina.  Apparently she was more than ready as she was very wet and I sunk in deep without any trouble.  We fucked for a couple of minutes when she disengaged from me.  She went and picked up the twins and brought them to the couch.  She then lay down and spread her legs and told me to get with the program and fuck her.  She then offered a nipple to each twin.  I was treated to the sight of John and Carrie happily sucking while I slowly pumped my dick in and out of Susan’s vagina.  I reached down and with a circular motion gently rubbed Susan’s clit.  I could tell she was getting close, as she couldn’t keep still.  
She told me; "Don’t cum."  
She wanted to see Carrie suck my dick.  
She said:  “I want my juices to be on you when she takes you in her mouth.”  
With that Susan started to orgasm.  She let out a loud moan and both twins stopped sucking and looked at her.  John returned to sucking almost immediately while Carrie just looked at Susan then at me.  She wasn’t sure what was the matter.  I guess she figured everything was OK as she took the nipple back into her mouth.  Susan told me that she wanted to see Carrie suck me off.  I sat back on the couch next to her and moved Carrie so that her head was in my lap.  This time there was no hesitation as Carrie opened her mouth and started sucking the head of my dick.  
I told Susan;  Help stroke my shaft so I will cum quicker."
What a sexy sight!  John was sucking Susan’s left tit.  Susan’s hand was jacking me off into Carrie’s warm little mouth.  
I softly whispered to Carrie:  “Ok honey, your treat is about to come.  Don’t be scared when it squirts.  Be sure to swallow it all like a good little girl.”  
Almost immediately I started to cum.  I could see Carrie sucking and swallowing as each spurt entered her mouth.  She was eager to get it all and seemed to be disappointed when I was drained.  She continued to gently suck and as my penis started to shrink she was able to take more into her mouth.  It really felt nice.
After a little bit I pulled Carrie up into my arms and asked her:  Did you like your treat?” 
She smiled and shook her head yes.  I then asked:  “Did it taste good?”  
Again she shook her head yes.  I said:  “Open your mouth and show me if it’s all gone.” 
She opened wide to show me that none was left.  I gave her a big hug and kiss while telling her that she was a good little girl and that I loved her a whole bunch.  She hugged me back and giggled.  It wasn’t long before both John and Carrie were asleep.  We carried them to their cribs. Once back in the living room Susan told me that watching us was so very sexy.  
She asked:  “John does the same thing?  He sucks you and swallows just like Carrie.”  
I answered:  “Yes, they both seem to like the taste and are disappointed when I don’t have any more to give them.  I hope they never change their mind. Once they start to talk I’ll need to make them understand that they can’t tell anyone about their special treats.  Until then this will be a daily treat for them and me.”  
I continued:  “ I bet they might even suck on your clit.  It’s smaller than my dick and your nipple, but with a little encouragement I bet they’ll like it.”  We agreed to try later.
Just then the phone rang.  It was my mom calling to check and see if everything was all right.  I said we were fine and the twins were down for a nap.  She said she would stop by in a little while to bring us something to eat.  I think that was just an excuse to check on us.  
Later mom rang the bell and came in to find us on the couch watching TV.  We all went in to check on the twins and found them just waking form their nap.  The odor announced that they needed to be changed.  Mom watched as Susan and I removed the diaper.  Yuck!  There was poop everywhere.  
Mom said:  “Bring them into the bathroom and we’ll get them cleaned up.  I’ll show you how to give them a bath so in the future you won’t have any trouble."
She showed us how to protect their head while we soaped up and rinsed their bottoms.  She made sure that I knew how to properly clean Carrie’s little pussy.  She stressed how important it was to make sure she was clean.  The Twins seemed to like getting a bath and cooed and kick.  After they were dried we headed back to the nursery.  Mom laid a double towel down just in case they peed.  
She said:  “Don’t diaper them right away.  Babies like to be naked.  When you want to go back to the living room.  Diaper them and take them with you.  Don’t ever leave them alone."
I told mom thanks and gave her a big kiss and hug for helping us.  She gave Susan a hug too, before she turned and left.  As we stood watching the twins, we heard mom’s car pull out of the drive.  
Susan said:  “This is so neat.  I’m glad Julie let me have a turn.  Jim, I want to watch you suck Johnnies little wiener.”  
I told her; "I don’t think so."  
She said:  “With all that we’ve done I can’t believe that you balk at this.  Go ahead.  Julie and I don’t have a problem sucking you or each other.  That doesn’t make us queer.  We will be the only ones that know.  I promise.”  
I gave in and bent down and took his little penis into my mouth.  It felt so small and soft.  I gave it a little suck and looked into John’s eyes.  He had a smile on his face and kicked his feet.  He liked what I was doing for him.  I knelt by the bed and continued to suck his penis.  I rolled my tongue around his penis while sucking and humming.  At the same time I was sucking him I was rubbing his tummy.  John sure seemed to like what I was doing to him.  I decided that I liked doing this to him too!  
I glanced over and saw that Susan had her mouth covering Carries little pussy.  Susan was licking every inch of her crack, from her anus to her clit.  We did this for a long time.  At one point we switched and I sucked Carrie’s pussy and Susan sucked and licked John’s penis and ball sack.  I think she even tried to push her tongue up his little anus.  We agreed that we would have to do this again and share with Julie.
Before Nancy came home I fucked Susan filling her vagina with a good load of sperm.  When I finished I took Carrie and placed her between Susan’s spread legs and moved her up to within an inch of her pussy.  Carrie smelled that familiar scent of sperm and stuck her tongue out for a taste.  Recognizing the flavor she eagerly licked all she could get.  After a couple of minutes I replaced her with John.  I stuck my finger into Susan’s vagina and pulled some more sperm out so that John could lick it up.  There was no hesitation on his part either.  He licked until it was all gone.  I moved him up a little and he started to suck on her clit.  He seemed to lose interest because he wasn’t getting any more sperm.  I bent down and gave all three of them a kiss.  I told the twins that they were so very good and that I loved them so much.  
Susan and I washed their faces so that the only smell to be detected was soap.  We didn’t want Nancy to suspect anything.  It was a great day.  Later that evening Mom called Nancy to tell her that she dropped in to check on us.  She said the twins had soiled themselves pretty bad and she showed us how to safely give them a bath.  Nancy was delighted and thanked her for being so helpful.  She said she felt really good about leaving her babies with us.  If she only knew!
The rest of the summer was pretty much the same activities.  The twins really developed a taste for my sperm.  They would eagerly take me in their mouths and suck.  They would have me cum several times a day for them.  It seemed like they couldn’t get enough.  The only new twist to our little sexual games was when Carrie and I were naked.  I’d have her sit on my lap with my dick laying in her slit.  She would squirm and rub her pussy up and down my dick.  She seemed to like this little game a lot.  A couple of times I’d get too excited and cum making her slit real wet and slippery.  Then she would rock back and forth faster.  I then reached down and scoop up some my cum and feed it to her.  She eagerly took it.  Then, with a big grin on her face she gave me a big hug.  What a nice little lover she had become.  Every time I’d come over she would crawl to me and want in my lap.  She wanted to rock on my lap rubbing her little pussy against my dick.  Each time I’d get hard and she would rock faster.  This became a favorite game of hers.  
It was toward the end of summer when mom relayed the news to us that Tom, Nancy and the twins were going to move away.  Tom had received a promotion and had to relocate to another state.  Nancy said she knew how fond we had become of John and Carrie but the move couldn’t be helped.  This was a big advance in Tom’s career and couldn’t be turned down.  It was less than a month later that they were gone.  That left a big void in all three of our lives.  We really grew to love those ‘little bundles of love’.
Susan said to me:  “I know we said we would love each other for ever and I hope that never changes.  If we do wind up married, I want our children to experience what we gave to Johnnie and Carrie.  They loved what we did with them.  Our children will want and need that kind of love too!  We will never force them into anything.  It will have to be their request to take each next step.  I just want our family to enjoy each other as we enjoyed the twins.”
I pulled Susan into my arms and gave her a passionate kiss.  I told her that I felt exactly the same way, but had some reservations.  Sex was to be shared openly with our children, but must never forced.  
Susan added:  “We have a special relationship with your sister.  If Julie wants to share that love with our family then that would be OK with me.  I like making love with her included.  She has been our partner since the very beginning.  We will have to be careful though, whoever she marries might not feel the same way.”
I agreed and just held her close enjoying the warmth of her body.  I whispered in her ear:  “I love you!  I can’t imagine life without you.”
Her response was:  “Mmmmm.”
