This is four months on.
After what happened on the camping trip I just assumed we would continue to be lovers. I knew it would end after the baby was born, when Vicky and Paul would start having sex again, but until then we would find ways of meeting in secret. Unfortunately it didn't work out that way. Paul's ankle was worse than we thought, it was fractured and he needed a cast. He spent two month off work, Vicky had to do all the fetching and carrying for him. It was frustrating and annoying because I got the feeling that Paul could actually do more for himself. He has always been lazy. Two weeks after we got back we did try. Paul was downstairs and I was with Vicky in the bedroom. If we kept the noise down we could have a quickie. We shared a passionate kiss then she removed her knickers. As I unzipped myself she bent over, ready for me to take her from behind. It was only the creaking step that saved us. Paul had managed to hobble up the stairs. When he entered we were decent, but it was a close shave. Just before he opened the door Vicky had managed to kick her knickers under the bed, and I had managed to zip myself up. That made us more cautious, but before we could try again I got a girlfriend, Mary. I don't really know how I managed it, she was definitely out of my league. From then on I selfishly avoided my sister, until the following happened.
--------------
I was at home in my bedroom sulking. Mary had finished with me three weeks ago and I was still licking my wounds. Deep down I knew it was inevitable but that didn't stop me feeling sorry for myself.
"George. Come down, Vicky and Paul are here."
I shouted back "Do I have to?"
Mother answered with a firm "Yes."
I sighed, I wasn't in the mood to see anybody but I knew that if I didn't come down mother would just keep on at me.
Vicky gave me a hug. It was uncomfortable because of her large bump, and because it brought back memories of the camping trip. I was starting to get aroused but thankfully she let go and then stepped back. Giving me a good long look she said "You need cheering up." She then added "I discussed it with Paul last night, we need another camping trip."
I wasn't expecting that. I then thought of what had happened last time.
"Say something."
"Sorry sis. Yes it's a good idea. Thanks."
In a disappointed voice Vicky said "I thought you would be more enthusiastic about it."
I forced a big smile and said "I am. It's just that you took me by surprise."
"I enjoyed it last time and I know you did as well." After a slight pause she continued with "This time it's going to be even better."
As she said it she gave me a look that suggested there would be more to it than just a simple camping holiday. I just hoped my face wasn't showing what I was now thinking.
"Paul is not coming with us."
I looked at him for confirmation. "That's right, my ankle has only just fully healed."
Mother said "I am not sure if I should."
Before mother could say anything else Vicky decided for her. "It will be too much for you."
Mother hesitated, and I held my breath, then she said "Yes."
In a slightly irritated voice Vicky said "Yes it's too much for you or yes you want to come?"
"It's too much for me."
Vicky smiled and looked at me. I then realised that she had got what she wanted, a camping trip just for the two of us. What had been hinted at before was now a promise. My whole mood changed.
With obvious delight in my voice I said "When are we going?"
"Give me a day or two to sort it out. I am thinking of a weekend away in the next few weeks." She then added "We can't go too far away in case the baby comes early. I have two more months left but you never know."
Paul sounded serious as he said "George I have insisted that you share a tent with Vicky. It will be safer if you are both together." He then gave me a stern look and said "I will not take no for an answer."
I was obviously ecstatic on hearing that but I tried not to let it show. I casually replied "OK" then I looked at Vicky. Did she just give me a secret wink?
I couldn't wait for the trip to start, the last few days seemed to drag. Vicky did all the organising so all I needed to do was to pack my camping gear, and the one tent we would be sharing. We would travel down on the Friday evening, after work, and return Sunday around mid-day. All I could think about was the two nights we would spend together.
"Have we got everything?"
"Yes."
"Are you sure?"
"Come on sis you know me, I have checked everything twice."
"Check it for a third time."
I was about to complain when she laughed.
"Very funny, you got me."
It only took us one and half hours to get there, and that was after losing nearly ten minutes on a wrong turn. Vicky was driving and I was navigating. I had spent the first few minutes complaining, why didn't she have a Satnav? She calmly explained that she was getting a new car, with one, in the next few months. I started up again. In a more irritated voice she told me that if I didn't shut up I would be sleeping in the car tonight. I then stopped complaining. When we got lost I was tempted to mention the lack of a Satnav again, but I had the good sense to keep my mouth shut.
"Do you like it?"
"It's a bit small, and a bit crowded."
"Well there wasn't a lot of choice. There was one that looked really good but it would have taken us at least four hours to get there." Then she added "The weather is very mild for mid-March so every man and his dog are out camping."
When she had finished, with perfect timing, we heard a dog bark. I said "That's the dog, where is the man?"
We both laughed at that and then I gave the site another look. It would do, we were only here for one thing and it was not the camping.
I picked our spot. Ideally I would have liked to be further away from the other campers but nothing better was available. We were quite close to another tent, but other than that we had our privacy.
As I started to pitch the tent there was a shout. "Do you need a hand?"
I turned around and saw a man smiling at me, there was a woman next to him. He pointed to the other tent and said "That's ours."
We introduced ourselves. They were a married couple in their sixties, James and Margaret. They seemed very nice.
Margaret asked "When is the baby due?"
Vicky patted her large bump and said "Just two more months, but I wish it was now."
We all laughed at that. James then looked at me and said "Your first child?"
Before I could say anything Vicky gave a quick "Yes." She then held my hand and said "The first of many." Our new friends found that very funny.
When we were alone I asked her why she hadn't corrected them. She said it was just a bit of fun, she liked the idea of us being together. When we returned home we would never see them again so there was no harm in pretending.
We spent the rest of the evening sitting outside the tent, enjoying the mild weather. James and Margaret had gone for a late meal, they had invited us to join them but Vicky declined. I was glad because there would probably be some awkward questions.
"Come on Vicky, tell me how you two met?"
"How long have you been married?"
I could think of a lot more questions they might ask. If we were going to spend time with them we needed to get our story sorted out.
When it was time for bed I could feel the tension between us. We both knew what was going to happen but nothing had been said. I had expected Vicky to say something in the car but she hadn't. I opened up the two sleeping bags, we were going to use them as blankets.
In a hesitant voice I said "Are we ready?"
Vicky didn't reply, she just held my hand and smiled. I turned the torch off and we were now sitting in almost complete darkness. I cradled her head and then kissed her, soft at first then firmer. She responded by pushing her tongue into my mouth, I sucked on it eagerly. We then took turns at exploring each other's mouth. It felt as if we were never going to stop, but we did when Vicky pulled her head away.
She gave a sort of purring sound before saying "That was wonderful. A nice starter."
'What's the main course?"
"Me." Then she giggled like a school girl.
There was silence for a few seconds before she added "I have waited a long time for this, too long." She then paused before saying "I thought that when we got here I would make you fuck me within the first ten minutes, as soon as the tent was up. However I now realise that we have all night, and all tomorrow night, so we can take our time."
As I stroked her hair she continued, "I have been so frustrated these last few months. The last fuck I have had was from you. There is only so much satisfaction you can get from your own fingers. I need a cock. I want you to promise me something."
In a puzzled voice I said "What?"
"I want you to promise to do everything I ask. I want to be fucked every way I can think of."
"Wow, I think that's a promise I can keep."
We both laughed at that, then in a serious voice she said "Time to play with my tits."
I was eager to do as she asked. Her tits were now noticeably larger than before, as I slowly unbuttoned her blouse I wondered if her nipples had grown as well. When the last button was done Vicky slipped her top off and then reached behind to unhook her bra. I was already playing with her tits, searching for the nipples, before the bra was off.
"Damn, I am all fingers and thumbs." Then in a frustrated voice she added "I can't unhook it."
"Let me."
It would be a lot easier for me. However I also struggled with it, but eventually it was off.
There was a sigh from Vicky then she said "I thought it was never coming off."
"Me too."
She laughed at that, but the laugh turned into a moan when I found her nipples, they were bigger. As I pinched and rubbed them she moaned continuously.
"Suck them."
"No, not yet."
"Suck them, please."
She was almost begging, I had better give her what she wanted. I put my mouth over a nipple, she gasped. I then slowly licked the top of it.
"Suck it, suck it hard."
I continued licking for a few seconds, then I sucked on it as hard as I could. I heard her catch her breath, then slowly exhale as I started to suck more gently.
"Fuck me, that almost made me come."
I stopped and quickly asked "Do you want me to do it again?" I then got back onto her nipple.
