Third and final part of the triplets tale. Sorry it took so long but I ran out of idea's for a while. May (but only MAY) try to write this from the girl's POV at some stage. Hope you like!
***
We were about two-thirds of the way through our parentless summer and for the three of us the days had settled into a rhythm. Every morning we did our designated chores for the day before spending some time doing our own thing; meeting friends, doing some personal shopping, maybe some reading, just stuff to give the outside world the idea that nothing else was happening between us. We got together for one or two meals a day, generally prepared by Pam. I offered to cook sometimes, but the general feeling I got from my dear sisters was that they'd rather starve. After the evening meal had been cleared away we'd talk; sometimes for just a short while, sometimes for longer. But we'd always end up in the same place; our parents double bed. Even then we didn't always make love. On occasion we just lay with our arms around each other, enjoying the presence of our sibling's naked bodies.
It was during one of those quiet nights that Pamela sparked off our next erotic experiment.
"I wonder how it feels to have two cocks inside you." She said out of the darkness beside me.
I looked around into her eyes, bright in the night; she meant it.
"I don't think I can help you there Pammy, I've only got the one, sorry." I grinned.
"I think it sounds cool." Pippa piped up from my other side. "Hey! Maybe we could get another guy?" The question hung in the air while we all thought about it.
"Nah!!" All three of us said at the same time.
"How about the vibrator?" I asked.
"I don't think that would be quite how I meant." Pam said dubiously.
"I know!" Pip sat up. "What about one of those harness things with a dildo that girls use?" She said brightly.
"You mean a strap-on?" I asked in puzzlement. Surely Pip knew what they were called? I had the feeling I was being set up again some how.
"You're the porn expert." Pip smirked.
"That will so work Pipsqueak." Pam sat up too with a grin on her face, reaching across me to kiss her sister. Now I knew they had planned this earlier.
"Where are you going to get one of them?" I said as they kissed above me, deliberately teasing.
They broke the kiss.
"Well, I heard about this new adult store opening somewhere in town. Maybe I can find it tomorrow." Pip said.
"Then I'm coming with you. I don't think you should go into one of those sort of shops on your own." I said firmly, trying to ignore the fact that Pips hand had now slid down to my dick and was slowly pumping it.
"I'm coming with you." Pam said, her hand joining Pip's.
"Are you sure Pammy? You might get embarrassed at the stuff in there." I said, trying to ignore what Pip was doing. I was a little worried, I always knew Pamela was more sensitive than the outgoing Pippa. The way their hands were moving on my dick was making me sensitive in a different way. Much more of their digital manipulation of my cock was going to bring me off. I told them that and a little reluctantly they stopped but left their hands in place.
Pam spoke again, obviously having considered my worries.
"No. I'm not letting you two loose in a place like that; who knows what you'll buy."
"Pam! I'm shocked that you think so little of us." I said in mock astonishment.
"She has a point though." Pip laughed.
"Fat lot of help you are Pippa!" I laughed too, so did Pammy. "Okay then: Tomorrow the three of us will go and find this place." The girls murmured their agreement and then went back to massaging my dick.
I had been ready to fall asleep but the feeling of the two hands on my cock pushed all thought of that aside. I lay back and let them do what they wanted. I sighed as the hands disappeared, thinking they had got bored, but sat back up as I felt two sets of lips replace them. I looked down and saw a pair of smiling faces at work around my rigid tool. Between them my sisters licked every part of it, from the tip leaking pre-cum to below my ball sack and every part in between. It soon became too much and I shot several strings of cum over both their faces.
"You both wear it well." I smirked.
"Let's clean each other off." Pip said, licking at Pam's face.
"After you little sis." Pam replied. That was the last thing I heard as I finally got to fall asleep.
When I awoke my sisters were already up and about as usual, I could hear them moving around downstairs. I rolled out of the bed and showered before venturing down to join them. The pair of them were sitting at the kitchen table drinking coffee when I came in. They were obviously waiting for me for some reason. Pam got up and made me a mug of the hot brown coffee, pushing it across the table to me as I sat down. I sighed as the drink finished waking me up. They were both looking at me expectantly.
"Ready then?" Pip asked as I finished the drink.
"For what?" I replied.
"Our shopping trip to the sex shop dopey. You are slow in the morning sometimes."
"You meant that last night?"
"Of course we did." Pam joined in. "Pipsqueak and I have done a little research and found out where it is. We can be there and back in an hour."
"As long as you don't get carried away." Pip added cheekily.
"Me!? Whose idea was this anyway?" I rejoined with a grin.
"All right, all right. Just hurry up with that mug and we can get going."
"Eager aren't we?"
"YES!!" They chorused.
With a sigh I got up and swilled out the coffee mug.
"Come on then." I said, picking up our car keys.
I suppose I was expecting a seedy looking back street shop. Instead it was a small unit in an industrial estate. Inside it was an airy warehouse with wide aisles and high shelving with the adult goods on display. Even though I was having sex with my siblings it felt strange taking them to a place like this: Hell, it felt strange just BEING in a place like this. The girls soon saw the sort of thing they were looking for and began to compare several different strap-on's. I wandered off by myself to explore the rest of the place. I came up to the bondage equipment and stopped. As I looked at some of the more serious implements I found myself hoping that Pip had been kidding about going further than just having her hands cuffed. These things looked painful and I knew I could never hurt her or Pam even if they asked me. I moved away quickly in case they saw and came over to look. I found the 'fantasy costumes', short, plasticky versions of uniforms. They looked nowhere near as sexy as my sisters' old school uniforms did. I walked away and wandered further down the aisles, wondering if there was anything at all here that interested me. I circled the warehouse and had made my way back to the entrance. It was then that I saw there was: My two beautiful sisters at the checkout with a bag each. I caught up to them and we left for home.
When we got back home my two sisters disappeared upstairs, clutching their carrier bags and giggling. It was obvious to me that they had bought more than just the strap-on we'd gone for but they were not going to tell me what. As I parked the car I had seen that it was about time the lawn was mown. I sighed to myself; that was one of my chores. I went to get the mower from the garage.
Trimming the grass didn't actually take that long, but as I returned the mower the garage door got stuck. It took me well over an hour to fix it. Consequently I wasn't in the best of moods as I entered the kitchen to clean off. In spite of being back for nearly two hours there was no sign of my sexy siblings so I grabbed a cola and went into the lounge to wait and see what the devils were up to. I had barely sat down when one of them appeared in the doorway, throwing a sexy pose before giving me a sultry look. For the first time in many years I was unsure whether it was Pam or Pip. The pose and the outfit, silky black lingerie and stockings, were pure Pippa, but it didn't seem as effortless as usual. Just this once I was unsure which sister was standing in front of me. Whichever one of them it was, they sashayed their way over to where I was sat on the sofa and draped themselves over the arm at the other end to me. As I stared into the face I could tell that it was Pammy; her eyes told me. A further look told me she was nervous too.
"You look absolutely gorgeous in those Pam." I said in a voice just above a whisper. "Truly stunning. Did you get them at the shop?"
"Yes." She said a little breathlessly. "Pip said it was about time I got something a little sexier than my usual undies."
"You look sexy whatever you wear." I assured her. "And I suspect Miss Pippa wanted you to buy those wispy garments so that she had an excuse to get herself something as well."
"So, do you like my new underwear?" Pam looked at me almost fearfully.
"Of course I like it silly. But you don't have to impress me. I think Pip plays us both at times, so that she can get what she wants." I paused, realising I was being a bit nasty about Pip without meaning to. "What did she get?" I asked to cover myself.
"I don't know." Pam replied. "Whatever it was, it was quite small, it went into the same carrier as the....you know?" She blushed in that delightfully simple way she had sometimes.
"No doubt we'll find out later." I sighed. "Now come here and sit on my lap in all your fine lingerie." I smiled. "I need to investigate fully."
Pam smiled as she slid across to me and threw her arms around my neck. Our lips met in a passionate kiss and our tongues danced momentarily.
"You don't love Pip more than me then?" Pam asked as we pulled back a little.
"I told you before; I don't love either of you more than the other." I admonished her. "I love you both the same, but probably for different things. Things that I'm not going into detail about because I don't want the two of you jealous of each other about anything."
Smiling, Pamela lowered her lips to mine again, our tongues entwining as they met.
"You are a wonderful brother you know?"
"And you and Pip are very special, very sexy sisters." I said, kissing her softly.
"HEY! No starting without me." Pippa called out as she entered the room, naked except for the strap-on jutting strangely from her groin.
"Well hurry up then slowcoach." Pammy grinned. "How long does it take to do up a couple of buckles anyway?"
"Wasn't just the buckles." Pip muttered, reddening at the same time. Pam and I waited. "What?" Pip said.
"If it wasn't the buckles what was it then?" Pam sighed. Then with a sudden insight: "Was it the extra things you bought then?" As she asked that I noticed the two small battery packs clip to the strap-on harness. There was a lead from each one disappearing under the device, one towards her cunt, the other her ass.
