Lustful Affairs (Erotica)

He blushed. “It could work. Did you read about that in the article you mentioned?”

“No. The article made no mention of relief. Just that the erection lasted for hours.”

“You should crawl out and wait outside. I’ll relieve myself, then I’ll follow you.”

She raised an eyebrow. “But what if it doesn’t work? You’ll be stuck here by yourself.”

“Good point.”

“Just cum,” she said bluntly. “It’ll be fine.”

“Are you sure?”

“Then get to it,” she said hurriedly.

“But that means you’ll see my dick.”

“Your balls too,” she added.

He lifted an eyebrow. “You don’t mind?”

“Like you said a moment ago, if Mom and Dad see this, they might think we were fucking in here.”

“Oh god.”

He stuck his fingers underneath the elastic of the swimming trunks.

“Need help?” she asked.

“Yes, my arms are weak.”

Kristen reached over and yanked her brother’s swimming trunks down. She expected to see a hard cock. What she didn’t expect was a hard cock swinging back and nearly hitting her in the face. She moved her head to the side swiftly like she was playing dodgeball.

“Oh wow,” she gasped. “That looks serious.”

She stared at his cock, which curved upwards and was swollen to the point where it nearly turned a shade of red.

“I know. It’s way harder than usual. Do you know anything about this?”

Kristen inspected it closer. “Hmm. Wiggle it.”

“How?”

“Move it, up and down.”

Matt bounced up and down, moving his cock as his sister requested.

“Now side to side,” she commanded.

Matt stood in place and continuously turned his waist so that his cock waved from side to side.

“Any thoughts?” he asked.

She grinned cheekily, “It’s a super hard dick.”

“Thanks for the expert advice.”

“Hey, I’m doing the best I can. Now let’s get it done. I’ll assist you however I can.”

“Fine, and remember, this is your plan.”

“But it’s your cock,” she quipped.

“Touche.”

Matt grabbed his steel hard cock. He start to pump his hand up and down, and then stopped.

“What’s wrong?” Kristen questioned with concern.

“My hands are weak. I’m not sure I can make it cum.”

Kristen got up and went over to the other side of the cave. She kept her ears peeled and listened attentively to the echoes.

Sure enough, she heard the Thai tour guide speaking from afar. The tour guide made a joke and the group of tourists laughed. Most unsettling of all, she recognized the laughter of her parents.

And they were headed this way!

She rushed back to her naked brother and his hard cock.

“I think they’re coming,” she hissed.

“I’ll try again.”

“I don’t want to damage your beautiful cock,” she said. “Err… I meant… you know what I meant. Anyway, I have a plan.”

“What is it?”

“Remember when I lost the race? Then you won the best bed? If I got you out of this mess, with your cock still intact and feeling better than ever, will you give me the bed?”

“Hell yeah. What’s the plan?”

“It requires you to relax,” she said.

Kristen wrapped her fingers around the hard cock and she gave it a loving stroke. Up and down.

“Ummm… what are you doing?”

She kept stroking. “I’m getting you out of here. Face it, if you don’t cum, you’re trapped. Your body is too big and the current state of your dick makes it impossible for you to squeeze through that hole.”

“You’re so bad.”

“That’s no way to speak to your caregiver.”

She kept on stroking her helpless brother’s cock using a simple handjob technique. Under normal circumstances, her traditional clench and stroke would have made a guy cum in 10 minutes or less. With the effects of the toxin, she’d likely require more effort.

Time was of the essence and each second was precious.

“How long will it take?” she asked. “How about if I go faster?”

She stroked faster and harder.

“Not sure,” he moaned. “Damn, that feels good.”

As she stroked, feeling Matt’s cock pulse in her hand, she made other calculations as well.

“I need to preserve my arm strength,” she said. “If I keep jerking you like this, it’ll be harder to swim back.”

“Do whatever you need,” he replied, enjoying the experience.

“You better appreciate this.”

“Of course, I do.”

Kristen bent down and fulfilled a longtime curiosity and dark fetish by taking her brother’s dick into her mouth. As tense as the situation was, this was also the perfect pretext to suck him off.

She closed her lips around the stiff shaft and had her way with it. She sucked it tightly and bobbed her head while stroking it with her tongue. She could feel it pulsating and throbbing in her mouth, far more than any other cock she’s ever had in her mouth. In a way, she was glad Matt was bitten by whatever it was. She was curious as to what that toxin was.

His moans echoed in the cave. As did Kristen’s sucking and slurping. It was the first time she was able to hear herself suck so vividly and it was such a turn on. But listening to Matt in desperate sexual despair because of what her mouth was doing to him was the ultimate turn-on.

“Oh God, I’m close Kris,” he said in a low voice. “I feel like I’m going to burst!”

She spit the cock out for a moment. “You haven’t earned full-on mouth cleaning privileges yet..”

“Okay,” he didn’t complain.

“You’re the best cocksu— I mean, you’re the best sister alive.”

She stroked hard and fast. “I know I am. The best sister. And the best cocksucker. Always remember that.”

Then she went back to working her mouth around the shaft in an attempt to make him cum faster. She even took him deep in her throat because she knew that guys loved that. Her throat was the real ‘tunnel’ that men were interested in.

She almost gagged as she took it all the way to the back of her mouth, close to the center of her throat.

When she had the deepthroat, she held it, then listened. Laughter? In the background? The Thai tour guide must be a funny guy, and that gave her fair warning.

“They’re coming,” she hissed after spitting the dick out, freeing her throat in the process. “This isn’t working. Will my pussy help you cum faster?”

“Pussy usually works best, depending on how tight you are and how you work your hips.”

“Done. Lay down.”

Those were Kristen’s other specialties, aside from sucking and deepthroating a cock. Her pussy was tight and she learned how to fuck from other college girls. Perhaps this would be the stimulation her brother needed to speed up the orgasm.

She sat upright and climbed on her helpless brother’s lap. She pulled the crotch of her bikini bottom aside and positioned her wet pussy above her brother’s hard saliva-covered dick.

She held his hard cock upright with her fingers and slowly lowered herself onto him.

“We’re going to fuck,” she said matter-of-factly. “And you better cum. Fast. If we get caught, you’re a dead man. Got it?”

“Yes, yes. We’ll both be dead if our parents see this. Do it already.”

She lowered herself and her labia wrapped around the dick. Although her pussy was tight, entry was easy because of how wet and aroused she was from doing all these rather dirty things with her vulnerable and needy brother.

By the time Matt’s big dick had slid all the way inside of her pussy, they were both gasping in pleasure. Her hole was tight. The second tight hole which may well be the death of him.

She bucked her hips and began to ride him. She knew all the techniques of cock riding and pussy control. She learned about it online and from some of her slutty friends on the volleyball team. Who would have thought she’d ever these techniques on her own brother of all people? (Oh, how she had secretly hoped…)

Her hips gyrated hard and fast. In this position, and with the size of his dick, each thrust was hitting Kristen’s elusive G-spot directly. She wasn’t sure who’d cum first, herself, or her brother.

Why not both at the same time?

She clenched tightly and rode as fast as she could. Kristen was having the time of her life with that cock.

“Oh fuck, his cock feels so good,” she whispered to herself, eyes closed, digging her fingers into his stomach.

“What was that?” he whispered back.

“Oh, nothing. Hurry up.”

There was one last trick in Kristen’s arsenal. She knew it could be painful for both of them, but as the faint sounds of talking and laughter grew louder, she knew it had to be done.

She practically bounced on her brother’s cock, her athletic legs pushing her body up and down. Each bounce hit her G-spot. It was like something out of a professional porn shoot. And it was working.

After the tenth bounce on his cock, Kristen came first. “Matt.. I’m cumming!!”

Her pussy and G-spot were so overwhelmed that she had to clench her jaw to keep herself from screaming at the top of her lungs. If she had, and the tour group heard it, then they’d really be fucked.

Instead, she made short, suppressed whimpering noises. Her jaw and eyes were squeezed shut. Her toes curled as she squirted a small river all over her brother’s crotch.

“Hmm…” she whispered, her fingers digging even deeper into her brother’s stomach.

She gave two more bounces and saw Matt’s body jerk.

“Kris you did it. I’m going to spill. AAAAHHHHHH!!!!!” She felt a huge spurt of cum shoot inside of her body. She gave several more bounces on his cock, each one making him flood more cum inside of her.

They were both exhausted, sweaty, and in need of a long nap to recover from their unholy ordeal.

The voice of the Thai tour guide grew louder.

“And we are soon approaching the most exotic cave in this entire complex.”

It was becoming too close for comfort. They’d be here at any moment.

“Holy fuck,” she whispered.

Kristen climbed off her brother. It looked like a bottle of glue had been spilled all over them. A mixture of his cum and her squirt were everywhere.

As soon as she released him, Matt was able to stand up, his cock was shrinking, dripping semen on to the sand.

Kristen grabbed her brother’s swimming trunks and headed for the opening. By the time they made it to the opening, Matt’s cock was back to normal. They both squeezed through the small opening. Once out, Kristen noticed the front of Matt’s body was coated in their sexual juices.

Right on time, too. They heard the tourist group enter that cave and marvel at the beauty of it. The siblings knew they had to pause and remain still for a moment, otherwise they’d be heard.

They listened to the tour guide show everyone around.

“Phenomenal as you can see…” the guide said before abruptly stopping. “It looks like creatures from the sea or land animals had gotten here before we did.”

The tour group laughed at what they saw on the ground.

On the other side of the cave, the siblings looked at each other with mortified expressions on their faces.

Kristen mouthed the words, ‘They’re laughing at our cum puddle. Oh my god.’

‘Let’s go,’ Matt mouthed quietly. ‘Don’t make a sound.’

The siblings tiptoed out of the cave. Once they were free on the sandy beach and open air, Matt put his swimming trunks back on. Kristen couldn’t help but sneak a final peek at her brother’s cock.

“Crap,” she said. “We almost got caught by everyone.”

“They saw our cum. Holy shit. Ha! Ha!”

Kristen smiled, “They all laughed, which means Mom and Dad laughed too, not knowing that the mess was ours. Anyway, race you back to the resort?”

“What do I get if I win?” he asked.

She pulled the front of her bikini down to show her pink nipples. Matt was stunned for a moment. Kristen took advantage of the situation and sprinted towards the ocean. Matt followed behind. The race was in full swing.All text © NôvelD(r)a'ma.Org.
