It was time to pack up and head for home. As they say, all good things have to come to an end. It had been wonderful, but to tell the truth, I was thankful that it was now over. I'd discovered that my Sister's sex drive was comparable to Lizzy's. She'd worn me out.
Fifteen minutes later, the car was loaded and we were in it, ready to leave. Jess turned the key. The engine spluttered a few times, but then thankfully it roared into life. I looked at her, and like me, she was relieved. Where we were was not a good place to breakdown. We were at least ten miles from the nearest town. Then to my surprise, she turned the engine off. Had we forgotten to pack something? I was sure that everything was in the car.
Turning to look at me, she said, "Do you remember the Jack and Jill story?"
Of course I did, we'd spent a lot of time while we'd been camping, either talking about it, or reenacting it with Jess as Jill and me as Jack. It was a story that I would never forget, even if I wanted to.
"I mean the ending."
Now I understood. After giving a loud sigh, I said, "Do I have to?"
That made her laugh.
"You know you really want to."
I did, but I wasn't sure that I could.
In the story, their final fuck had been when they were, like us, packed and ready to go. But they were fictional characters, fucking like rabbits wasn't a problem for them. However, I was only flesh and blood. There was a limit to how many times I could have sex in twenty four hours, and I'd reached it. In that period we'd done it three times, and the last one was only two hours ago. That had drained me. There was nothing left in my balls. Would she take a rain check? We could stop at Bob's Burger Bar on the way home. By then I'd be ready, and we could have a quick one in the restroom.
"I have a suggestion. Why don't we wait until we get to that burger place that we like?"
"You mean do it in the restroom?"
"Yes."
"I'd like that. I'll bend over so that you can fuck me hard from behind. And hopefully, there will be lots of other people using the restroom, so that they can hear us fucking."
"Thanks Sis."
"But it's not instead of."
It took me a couple of seconds to understand what she meant. She still wanted sex before leaving, and I'd actually made it worse, because later on we'd be doing it again in the restroom at Bob's Burger Bar.
After giving another loud sigh, I repeated what I'd said earlier, "Do I have to?"
This time she didn't laugh, and she didn't answer me, instead she just got out of the car. I then got out as well, like a lamb to the slaughter!
I didn't know how this would progress, but I didn't need to, because she was in charge. She would lead, and I would follow.
Pointing to a patch of grass, she said, "We'll do it there. Lie down, I'm going to get on top of you."
I did, and it got me a prod with her shoe, and it was painful.
"Very funny, now turn over."
I was now on my back. I'd thought that lying face down would amuse her, but it hadn't, and it had got me sore ribs.
I wasn't enthusiastic about this, but she certainly was, because she had my cock out of my jeans with a speed that was impressive. When she had it in her hand it was still limp, and she shook her head to show her disappointment.
Then after smiling, she said, "Not to worry, I can fix this."
But I was worried, because I didn't share her confidence. And if I was right, and it stayed limp, she would not be happy.
She then took my cock into her mouth. I wanted to resist. I wanted to stay limp to prove a point, to make her realize that I wasn't a sex toy that she could just turn on whenever she wanted to. But of course I couldn't resist.
As her tongue did wonderful things to the head of my cock, the blood started to flow into my flaccid member. At first a trickle, but very soon it was a torrent. It wasn't long before it was rock hard. I hadn't thought it possible. She'd got it back to its best, and in less than five minutes.
After moving her head back, so that my cock was now out of her mouth, she said, while grinning from ear to ear, "That's better."
It was for me as well. Now that my cock had woken up, its appetite for pussy had returned. And just thinking about fucking her was making it twitch.
When I reached for her tits she brushed my hand away.
"Don't move."
I lay back down again, and then I put my hands behind my head to make myself more comfortable.
"That's better. I don't want you to do anything."
I was now expecting her to just take her jeans and panties off, and then quickly get on top of me so that she could ride my cock. Instead she started with her T-shirt, and she wasn't in a hurry to remove it. When it was off she started massaging her tits through her bra, and then pulling on her nipples. After doing that for a while, she stopped so that she could unhook her bra. When it was off she bent over me so that one of her nipples was tantalisingly close to my mouth, but when I raised my head she moved away.
"I told you not to move."
I sighed. This was payback time. Initially I'd been reluctant, and she'd had to be forceful to get me out of the car. Now that I was as eager to fuck as she was, she was going to make me wait. She was going to tease me.
This time, when her nipple was again near to me, I didn't move. But I did open my mouth, ready to receive it. However, her wicked grin told me that she wasn't going to let me suck on it. This was now more than teasing, it was torture.
Fortunately for me, even though she'd climaxed only a couple of hours ago, she was eager for another one, so it wasn't long before she stopped. And she was now quickly taking her jeans and panties off. I was relieved, she'd stopped playing games.
When she lowered herself onto my cock I groaned, but it was drowned out by her gasp when my cock was fully in her. There'd been no hesitation from her. She'd taken all of my eight inches in one go. And she then didn't just sit there, waiting until she'd got her breath back, she was quickly moving again.
She'd chosen reverse cowgirl. Normally I would have preferred her to be facing me, so that I could play with her tits, but this time it didn't matter, because I wasn't allowed to touch them.
After only a few seconds I realized two things. The first was that she was an expert at this. Every time when she lifted herself up, she was high, making sure to use the full length of my cock. And then she was sitting down on me with a force that meant that I went into her as deep as possible. The second thing was that this was all about her needs. Very soon it would be mission accomplished, because she would come, and whether I did or not, was of no concern to her.
As she got more excited, and closer to reaching it, she moved quicker. She was now also sitting down on me so hard that it was becoming uncomfortable.
"I'm almost there."
Then shortly after, when I was deep inside her, she collapsed onto me. Had she come, or had she stopped because she was exhausted? There were none of the tell-tale signs that I had seen previously to indicate that she'd climaxed. It had ended suddenly, with a whimper rather than a bang. Then I almost laughed. Of course she'd come. Knowing Jess, if she hadn't, then there was no way she'd have stopped!
It didn't take her long to recover from the strenuous workout she'd just had. When she got off me she noticed that my cock was still hard.
