Pol D. hugged his sister, Mariona, as soon as he entered the apartment. She was looking great; she’d lost weight and her skin and hair glowed. University life agreed with her.

“How are you? You look well!”

“I’m great, thanks. The course is amazing, and I’ve met so many cool people.”

“Good, good.”

“And you? Good journey?”

It had been a good journey. He’d got quite a lot of writing done on the three-hour train to Valencia, and he’d emailed his editor the copy. He’d earned the evening off to hang out with Mariona. He’d missed her since she’d moved away. Of course, he was glad to see her spread her wings. But there was still an absence in the home where she had been.

“We’re booked in for dinner tonight. There’ll be four of us. Us, Jonatan, and his sister.”

“And Jonatan is…?”

Pol couldn’t help but smile as he teased his sister. He had no doubt that Jonatan was…

“I’ve been seeing this guy. He’s so cool. You guys will get on, for sure.”

“Good for you.”

And he meant it. He wasn’t the type to resent his sister for the domestic happiness that he had not yet found, even if she was younger than him.

 “So, brother, any developments in YOUR love life?”

Pol shook his head almost unwillingly. He had slept with a woman four days ago if that counted. Briefly, the image of Ana riding him flashed into his mind. She wore her body well. Her skin was pale, her hair was long and black, and her breasts were large. Her belly was the perfect size. Neither thin nor fat, but perfectly proportioned. He’d enjoyed gripping her flesh as she rode him, feeling her tighten around his cock.

Ana had not been an adventurous fuck. She’d only attempted or invited him to two positions, endlessly repeated. Cow-girl – missionary. Cowgirl – missionary. Eventually, she’d helped him finish with her right hand.

Pol had screwed her, and she’d left. And he’d finished the bottle of wine they’d started alone. Then started another. He hadn’t called her yet.

“I’m looking. Halfheartedly, perhaps. But I’m looking. I’m quite set in my ways, you know.”

“Yeah, I know. Come on, let’s get ready. They’ll be waiting.”      

When they met at the restaurant, Mariona kissed Jonatan square on the lips. This surprised Pol. She’d always been coy about public affection with boyfriends before. Clearly, Jonatan was making an impression on his sister. The woman with them introduced herself as Carla, Jonatan’s sister. Carla was short and dressed in leather pants and a blue blouse. She had curly blonde hair down to her shoulders and a winning smile. Her eyes were a beautiful blue. Pol liked her on sight.

Jonatan was a cool guy. He had travelled widely and played football for a decent local team. Pol and he both supported Barcelona and they bonded over their recent triumphs and failures. It was a pleasant dinner, all in all, and they went on to a bar for a nightcap. At the bar, gradually, the foursome became two pairs as Jonatan and Mariona sat and giggled and kissed, and Pol chatted up Carla. When they were close, Pol smelt her perfume and brushed his hand on her hair. She was soon touching his arm and flicking her hair. They all left the bar and went home at about one o’clock.

“This is your room. The bathroom is downstairs. We’re next door if you need anything.”

They all shared a nightcap and retired to bed at about two o’clock. Pol rested his head on the pillow but, as is the way in unfamiliar beds, he didn’t just drop off. He lay awake, thinking about Carla. He imagined her knocking at his door. He imagined her moving in quickly for a passionate kiss. He imagined her pulling her blouse over her head, then reaching for his…

“Shhh,” he heard someone say.

Knock. Knock. Knock.

Something was moving in the next room. To his horror, he realized it was the bed. The bed was moving, and he knew exactly who was in it. His sister was in that bed. And now she was enjoying her boyfriend’s cock and he could hear…

Knock. Knock. Knock.

“Ah! Ah!” a gasping sound and the knocking increased in speed. Pol rolled over and put his hands over his ears. They might have waited till he was not there. He had to admit, to be fair, they’d drunk a fair bit.

“Oh, oh….” Then there was a high-pitched squeal. Pol buried his head under his pillow. But even with the sound muffled, his mind’s eye couldn’t help picturing Mariona on her back, her plump breasts jiggling as she was pumped. Pol had never wanted the oblivion of sleep more. He scrunched his eyes shut and tried to imagine it was Carla disrobed, Carla’s bed being shaken…

The giggling and the gasps went on and on until at last, it was only Jonatan moaning. Pol tried to believe that his sister was not sucking his dick, but he knew deep down she was. 

At breakfast the next day, Pol kept silent. But he saw his sister was in a vibrant mood, bustling around the kitchen and swaying her hips to the music on the radio. She looked like someone who had had her needs met.

They agreed to spend the day at the beach. The four of them swam and played volleyball. Pol watched Jonatan and Mariona splashing each other in the sea. They were far away. They talked and laughed, and Carla and Pol rubbed sun-cream on each other’s backs, in imitation of Jonatan and Mariona. The way her fingers pressed into his skin left him in no doubt she was interested. He risked it. Pol leaned in and gave Carla a kiss. She responded eagerly, and it went from brushed lips into a proper kiss. The sun was warm on his skin, and he was kissing a beautiful woman. What could be better?

The answer would come later that night. The four of them ordered a couple of pizzas and beer and hung out in the living room, smoking pot. Pol felt good. As excruciating as hearing the bed bump last night had been, he could see Jonatan was clearly an OK guy. And he was making her happy so who was he to complain? And Carla was gorgeous. He was longing for Jonatan and Mariona to go to bed and leave them alone. The hours ticked on though, and his heart was in his mouth when Carla got up to go to bed. He was going to miss his chance! Jonatan and Mariona swiftly followed suit and headed upstairs, leaving him alone with the last beer. Rolling his eyes, he cracked it open…

The door opened. It was Carla. Wordlessly, she held out one hand and put her finger to her mouth with the other. Pol allowed himself to be led to the next room, which it turned out to be her bedroom.

The door closed behind them. The change in atmosphere from the smoky, beery living room to the intimate air of the woman’s bedroom was stark. Femininity hung in the air here. He was immediately aroused. Carla jumped back onto the bed and then sat up, motioning for him to join her. He climbed on board and sat next to her. They leaned in and kissed, brushing lips, and he held her bottom lip between his. Her tongue made the first move and soon they were kissing passionately. Their hands began to stray. Hers grabbed his arm and ran down it. He ran his fingers through her hair, and the smell of the room and the kissing caused him to start to harden. Carla paused and slid down, so she was lying on her side. He joined her, and then their hands went wild. He caressed her bottom as she did to his, and he fondled her breasts. And they kissed more. He loved kissing Carla, and she was insatiable for his kisses. They made out for what seemed like hours.

At last, she began to unbutton his shirt. When he was topless, she leaned in and kissed his neck and then his chest.

“You smell so good,” she whispered. Pol was happy to take the compliment, especially as she was now kissing his chest. Now his belly. As she moved downwards, he grew harder. Carla kissed his belly button, then straightened up on her knees. She reached down and pulled off her blouse. The bra was off a moment later. Pol looked at her torso admiringly. He’d practically seen it all, of course, when she’d been in her bikini on the beach, but this was different. Her breasts were well proportioned, something like 32C, he guessed. Her navel was long and shallow. Cute. Her curly locks fell around her bare shoulders.

Carla reached for Pol’s trousers and, with a little wriggling on his part, they soon had them down. He was rock hard now. Carla leapt to her feet, unbuttoned her jeans, and dropped them. Then she got back into bed.

Now, they both only had their pants on, and the physical desire was mounting in them both. They kissed feverishly, and hands cupped genitals through the cotton. Pol felt that her crotch was damp. He felt like he could explode. On impulse, he left off kissing her and moved quickly down her body, until he was on his knees in front of her. He seized her knees and gently parted them, then he crawled forward. Her crotch was deliciously warm as he kissed it. He took her panties between his finger and thumb and pulled them down.

A minute later, his forefinger was inside her, and his tongue was tickling every inch of her vagina. He had never been with a woman he had been so instantly attracted to. And she tasted amazing. He buried his tongue inside her, and she began to moan appreciatively. Pol closed his eyes and recalled the image of her lying on her back in her bikini, then he pictured her pulling off her bra, and then he thought of how her ass had felt as he’d rubbed it, and still he licked her. Carla was gently rocking on her hips now, and Pol was harder than he had ever been. He had been licking her pussy for, what, twenty, twenty-five minutes? He had been picturing her body and enjoying her scent and her taste. He felt he could stay down there all night.

At last, though, Carla came with a moan. She pushed his head gently away.

“Good work.”

“Thanks!”

“Can I repay the favour?”

“Sure.”

He crawled over and lay on his back, and she scooted along the bed. Carla watched him pull down his pants. Pol’s cock was so hard, she didn’t think he would last very long. She took the base in her hand and pulled it up and down, then she knelt and gave it a lick. Pol wanted to reach over and jerk himself. It was almost instinctive as he was so aroused. He put his hands behind his head on the pillow to restrain himself and closed his eyes as Carla went to work.

The sensitive nerves on the end of his cock began to dance as they were embraced by the damp warmth of Carla’s mouth. The tip of Pol’s penis felt as if the lightest of electrical stimulation was being applied. He longed to jerk it, to reach orgasm, but she knew what a man really wanted. She was prolonging it, stretching it out. Teasing him. By sucking only the glans, she was denying him orgasm whilst making it feel so, so good. He was in ecstasy. He could think of nothing but what was going on at his midriff, so all-consuming was the experience.

At last, after ten minutes of pure pleasure, Carla dived down and took his penis deeper inside her mouth. With her thumb and finger at the base, she sucked and jerked him hard. Once – twice – three times – ahhhhh!

Pol’s orgasm shot out like a pistol into Carla’s mouth. His semen fountained out across her mouth, leaving a white line across the red tongue as if some slug had just crawled across.

“Oh my God. Oh my God.” He lay on his back, quite breathless.

He watched as Carla flicked her head back and, with a shake of her head that sent her hair (and her breasts) jiggling, she swallowed his load.

“Favour returned!” he said with a smile, wrapping his arm around her shoulders. She lay down with her head on his. After a few minutes of silence, she said, “I’m sorry. I don’t have a condom. I wasn’t expecting to…you know. Visiting my brother and all.”

Perhaps that was why she’d sucked his cock so willingly. This was a problem. As he’d come to visit his sister, he didn’t have one either. As he thought about what to say, she whispered, “But, if you like, we can do it…here.” She grabbed his hand and pulled it around to touch her bottom.

“Really?” He kept his hand on her ass, caressing her soft cheeks.

“Sure. Why not? You only live once. Never miss a chance to have sex. Or appear on television.”

“Have you tried it before?”

“Yep. Once. It’s good if you aren’t too rough.”

Pol had actually never tried anal.

They lay together quietly for ten minutes, until they heard from above them, the sound of the bed moving.

Knock.

Knock.

Knock.

“Ewwww! Gross! They’re doing it!” Carla giggled.

“Yeah. I think we need something to take our mind off the fact that our siblings are screwing above our heads.”

Carla nodded, but then a wicked grin spread across her face.

“Oh, I don’t know. Mariona’s quite hot. I can see her looking good naked.”

“Ugggh!” Pol exclaimed.

 “I can see her on her back, those big squishy boobs out, opening those legs and showing me that….”

“Aaaahhhh stop it! That’s my sister!”

“Hahaha!” she laughed.

“I can’t even take revenge. A guy would never imagine your brother naked.”

“Weird that.”

“Yeah.”

But then they heard

“Oh! Oh! Oh!” the squeals were unmistakably female. Mariona was enjoying herself.

“Ah, that’s my sister too! Come on.”

Pol grabbed the covers and pulled them over their heads. At once, the air was close and stuffy and it was hard to breathe, but at least the sound was muffled.

Now they went to work on each other’s bodies, and Carla reached for Pol’s cock to reawaken it, and he rubbed her thighs and buttocks and tickled the lips of her vagina and they kissed to lose themselves in each other and forget what was going on upstairs.

“Do you think they know what we’re doing?”

“Who cares? Turn around, show me that bum. I’m ready if you are.”

“Wait. I have lube. Can you use it, please?”

“Of course.”

Carla got up and out of bed. She rummaged in her bag. The couple upstairs were still moving the bed, but the cries had quietened for now. Carla handed the tube of lube to Pol and stood at the side of the bed. Then she placed her feet apart and bent over, laying her upper torso on the sheets, presenting her buttocks high and tight.

“Go for it.”

Pol squeezed the lube onto his left index finger, and then with his right fingers, he pried her buttocks apart. Then he slipped his finger between the cheeks and rubbed the lubricant around her hole. When it was lubed up, he slipped a finger inside her pussy to warm her up, then he added some lubricant to his cock and jerked at it until it was hard.

“Ready?”

“Yes.”

Pol nudged the opening of her ass with his cock, pushing gently against resistance. He felt Carla tense as she braced herself and then…

With a pop, Pol’s penis entered Carla’s bottom. She gasped as it did so and pressed closer to the bed. God, it was so tight. It felt amazing. Like wearing a cock ring or a condom that was a size too small.

“We good?” he asked.

“Oh yeah. Go easy, dog. I can’t scream, remember? They’re just upstairs.”

Pol began to thrust gently but, as he did so, a squeal came from upstairs, then another, then another. The bed was bumping more too. Jonatan and Mariona were going at it hard. God. His sister was being fucked just yards away. To take his mind off the sound, Pol thrust a bit faster. Carla responded at once.

“Oh, oh, oh. Yes. Oh, God! Oh, God!” She was moaning in a low voice. The penis in her ass was certainly enlivening her. Pol massaged her buttocks as he pressed in deeper. Carla was grasping the bedding tightly, and now she buried her face into the sheets. Pol’s cock was increasing in speed, and it must be approaching the pain barrier.  

“Can you slow down a bit?” she asked. He did, without speaking. Pol felt her sphincter contract a little, tightening around him. He wondered how it felt for her. An ex of his had put a finger up his bum once. But a finger was much smaller than his penis, of course. Without losing his rhythm, he opened the lube again and rubbed more around her hole.

“Oh…oh…oh. I’m coming.” She moaned.

“I’m close too.”

“Wait. Keep fucking me. Please. Do it harder.”

Pol was now in a fight to avoid orgasm. He closed his eyes and ran his left hand down her thigh, massaging her right buttock with the other hand.

“Oh! Ah! Faster!”

“Shhhh…they’ll hear.”

“I don’t care.” Her words were gasping, short of breath.

“I don’t care. Just fuck me. Bring me home.”

Pol sped up, pumping hard now. Carla lost control of herself and gave a great cry, half wail and half scream.

“Oh! Oh! Oooooooh!”

Pol was too in the moment to notice but upstairs had gone quiet. It was inconceivable that they hadn’t heard that and realized what was going on.

“Come. Come. Come!” she urged, still clasping the bed tightly.

“I can come in your ass?”

“Yes. Do it.”

A minute later, after six hard pumps, he came inside her. As he did so, his cock jerked forward, deeper into her than he’d ever reached. She squealed, and he gasped as his orgasm sprayed her innards.

Carla purred as he pulled out. When he was free of her ass, she scuttled to the bathroom, and he cleaned himself up with a tissue.

Carla returned after a few minutes.

“You OK? Not too painful?”

“No, that was awesome.”

“Agreed. You really don’t mind it? In your ass?”

“No. It’s different. But you weren’t rough, so it felt good.”

“If you say so.”

They made out a bit.

“I just had an idea,” Carla said.

“Oh yeah?”

“Yeah. Be right back.” Carla wrapped herself in a towel and hurried out.

Three minutes later, she was back. There was a condom in her hand.

“Ha! Where’d you get that?”

“Bathroom. I knew Jonatan would have some lying around.”

“If you’d thought of that before, you’d have saved yourself some discomfort.”

“Nah, I enjoyed it. Ready when you are!”

Ten minutes later, Carla expertly rolled the condom down Pol’s cock.

She climbed onto his dick and began to rock back and forth, back and forth. Pol looked up at her body. She was thinner than his last, Ana. Younger too. Younger, but clearly more experienced. Or at least with better training. She rode him, and he felt her vaginal muscles squeeze him

After five minutes, Carla climbed off, lay on her back, and let him in. Pol began to pump her. She was warming up when they heard someone go into the bathroom across the hall.

“Sssshhh,” Carla said. Pol stopped pumping, hanging just above her, supported by his arms.

There was no sound of the bathroom door closing. Just some moving about. Some rummaging.

“Oh, Carla!” Jonatan cried. “Fuck!”

“What’s wrong?” Pol whispered.

“This was the last condom.” She giggled.

Pol laughed, although he also hoped that would not mean his sister was in for an anal experience as a result. He resumed his stroke, and Carla lifted her legs and crossed them behind his neck. Oh, God, she was beautiful, her breasts melding seamlessly into her body. Her belly was soft and flat. Her blonde hair flowed around her shoulders. Her blue eyes looked up at him. He pressed in as far as he could go, savoring the moment. Carla ran her hands across his back.

“Go faster, I’m getting there.”

He did. He pumped faster and faster, and not even the squeals from upstairs as his sister was once again receiving her boyfriend’s attention could distract Pol. He shut out the noise and closed his eyes, focusing everything on the way her pussy lips were massaging his cock, the delicious feminine scent in the air, the way he felt like he wished he could make this last forever…

She came, writhing from side to side as an orgasm shot through her. He wasn’t far behind her and squirted what little was left of his semen (having come twice already) into Carla’s pussy. Pulling out a minute later, he realized he had shot a load into all three of her receptacles in a single night. Mouth. Ass. Pussy. Not bad going.

“I’m glad you came to visit.” She said as she lay next to him, her head on his shoulder.

“Me too.”

Now, it was nearly four o’clock. Pol and Carla both fell asleep, which meant that they were spared hearing Mariona’s muffled groans and squeals as Jonatan slowly, gently screwed her in the ass.

Over breakfast at midday, Pol saw that neither Carla nor Mariona were sitting entirely comfortably. They all acted, of course, as if nothing had happened. The foursome went for coffee and then Pol had to catch his train home. On the journey back, he thought of Carla and couldn’t help getting hard, even in the crowded carriage.

In the end, neither couple lasted. The distance was too much for Pol and Carla. Mariona graduated, split from Jonatan, and moved on with her life. But whenever he met her later boyfriends, Pol was reminded of Carla and quietly hoped that his sister’s latest lover might have a sibling of his own. And he never visited Mariona without a condom in his pocket again.
