Wet Heat

Nine AM the following morning, Jennifer and Jack were down at the waterfront in Manaus loading up the riverboat that Jack had taken possession of the previous day.

It was madness really. Jennifer's mother had begged her not to go but it had been her dream to sail up the Amazon since she'd been a little girl. And Jack was a decorated ex-Marine, so he knew a thing or two about boats and generally looking after himself.

He had a job lined up with an investment bank in London in three months and plenty of family money. Jennifer had just finished her PhD. This might be the only chance they'd ever get to do something like this. Besides, she had no idea what she wanted to do next, so was very keen to put off any decision for a few more months.

Jack was always up for an adventure so she hadn't had to push very hard to get him to agree. So, here they were, getting ready to go upriver into the heart of the Amazon.

The riverside quay was busy and there were many boats, big and small, moving up and down the river around them. It felt a long way from the glorious isolation, alone with nature, that Jennifer had dreamed of. But even as they first pulled out into the river flow, she could sense the bigness of the jungle around them and the smallness of this city, rudely irrupting where it didn't belong.

Soon enough, they were free of the city entirely. Jennifer waved goodbye to the improbable dome of its baroque opera house and they were finally plunging deep into the jungle.

Even this far inland, the river was still wide enough that the far bank was so distant that it could barely be seen. It was almost like being at sea. There were lots of other boats on the river, tourist ships, small boats like theirs, cargo boats and even a small cruise ship.

Jennifer lay on the deck sunbathing in her new bikini. She wanted to work on her tan but was so worried about burning in the fierce tropical sun that she had slathered herself in factor fifty. Mostly she was just enjoying soaking up the heat and the sights.

Jack had his back to her, piloting the boat. He was naked from the waist up. Jennifer liked being able to let her eyes wander freely over his strong back and broad shoulders. Jack didn't have the super shredded body of a bodybuilder but he was taut and strong and fit, the body of a soldier, of a man who needed to use that fitness for something, not just showing off.

Jennifer loved his body. It had always really excited her and turned her on. She was a bookish, clever girl who usually dated bookish, nerdy girls but she had met Jack in a bar two Christmases ago in their home town of Lincoln and had been thrilled by the raw masculinity of him.

She had let him take her home. And after he had made her come harder than she ever had in her life, she never looked back.

Lying in the sweltering heat, sweat glistening on her body, perving over her boyfriend's body, Jennifer could feel herself getting horny again. Even though she was in the skimpiest bikini she owned, the fabric felt too clinging on her skin and she longed to be naked.

Naked, but better still naked and fucking. She wanted to lick Jack all over and climb on top of him, have him penetrate her, have her, make her come. She loved how he made her come.

But it was illegal to sunbathe topless in Brazil and there were still too many people on the river. Their boat didn't have a proper cabin, although they could spend a night on it at a push. She was sure at nightfall it would be dark enough that they could get busy regardless but that was still hours away.

She glanced down at the crotch of her bikini bottoms and could see a small patch of dampness there. It could have been sweat but she knew it wasn't.

As a soldier's girl, not that he technically was a soldier as he kept reminding her, she was used to long periods without sex. Phone sex wasn't even really an option given the lack of privacy on base and difficulties in communication. She didn't really mind most of the time, and they more than made up for it when he was around. She had bought herself a good vibrator and a stack of steamy romance novels and that got her through.

But having him here, at arm's length and half naked and not be able to touch him, was unbearable. Well, there was nothing to stop her touching him of course but she knew that she wouldn't make do with just touching.

It wouldn't have been so bad if she could just masturbate. In fact, the idea of lying back on the deck of a river barge under the hot sun and touching herself while watching him was a very pleasing one, but for the same reason she couldn't take her top off, she could hardly do that either.

So she just fidgeted on the deck, rubbing her thighs together hoping it would be enough and knowing it wouldn't. She picked up her book, One Hundred Years of Solitude, but could barely concentrate. She felt cross with herself, here she was, living out her dream and all she could do was think about sex, like a horny schoolgirl.

Jack turned and looked at her. He didn't smile exactly. He very rarely smiled, but he had a light in his eye when he looked at her which was better than a smile from most people.

"You OK back there?"

Right now, the light in his eye had an amused look as if he knew exactly what his girlfriend was thinking. He glanced down to her crotch and noticed the wet patch.

"Of course," she replied, a little sulkily. If they'd been alone in their flat in London and he'd caught her in that mood, they'd have been stripping each other naked in no time. But as it was, she felt a bit cross to be caught out.

"Come up here and help me take the wheel."

She tottered to her feet, she might as well spend the time learning something.

Jack made way for her as she gripped the wheel. He stood behind her and reached round to put his hands over hers, guiding her with the tiller and the throttle.

His body felt good close to hers and she couldn't resist pushing her bottom back and into him. She moaned lightly as she felt that he was hard behind her.

He had one hand over hers on the throttle, showing her how to control the power in the boat's engine. The other hand slipped down onto her belly and down, down, under her bikini bottoms.

"Mmm, you horny bitch," he murmured as he felt her wetness.

"Oh Jack," she breathed back at him as he started to rub.

"Yes, Jack, yes, just like that. Make me come. Please make me come."

It was lucky they were in the middle of the sea-broad channel with no other boats around as Jennifer let the boat steer crazily to one side as she forgot about everything apart from Jack's hands on her clit.

"Oh fuck, Jack," she moaned as his fingers worked his magic. He had to grip her with both hands now, one holding her upright on her trembling legs, the other rubbing and rubbing as she started to lose control of her heaving body. The boat started to lazily drift back downstream.

"Oh yes, yes. Like that. Oh fuck. Oh Jack, yes!"

She called out as she started to come, her voice lost in the wide sweltering waters.

"Oh Jack, that was just what I needed."

She leant back into his arms as he reached around her to take back control of the boat. He kissed her gently on her neck.

She reached behind her to rub the throbbing bulge at his crotch.

"Can I take care of you?"

"Tonight," he replied.

"You sure you can wait that long?"

"Yes. I want to fuck you properly. Besides, I like being hard for you. "

"Ok. Suit yourself."

She let him take control of the boat again. She reapplied her suncream. Jack kept looking over his shoulder at her as she did, the hard outline of his penis very clearly visible through his shorts.

Jennifer adjusted her skimpy bikini and lay back in the hot sun, as it rose higher and higher. She felt like she was beginning to acclimatise to the tropic heat and torpor after all.
