My Girlfriends s****r

Brad tried not to stare. And failed miserably. How come Lindsey didn’t see it? Kayla was basically putting on a show.
The skimpiest red bikini she could’ve found was what she was wearing and she often bent over instead of crouching, she laughed, shaking her shoulders a little too much, making her generous breasts (even bigger than Lindsey’s, which was saying something), her curvier ass swaying more than what was necessary. But Lindsey didn’t see it. She swore her younger s****r was the same girl from eight years ago and not a young, voluptuous woman putting on a show for the man lounging in their back yard pool. The fact that said man was her s****r’s boyfriend didn’t seem to deter Kayla at all. Kayla made a hand gesture to beckon Brad. When he did come closer to the pool, she pulled his arm and mashed her breasts against it, hugging it with an imploring expression.
“Can you get me a soda?
Brad looked at his girlfriend. She looked back at him, as if her s****r wasn’t smearing her boobs against her boyfriend, with an expectant expression, urging him to fetch the soda.
Brad went for it, his back slightly bent forward to hide the incoming erection.
When he came back, he immediately gave her the soda and jumped into the pool. One of Kayla’s straps was halfway undone, one of her breasts about to pop out. He knew better than to say anything. Lindsey wouldn’t take it well, even if he wanted to keep Kayla under control and covered.
“Um. Lindsey? Wasn’t today the last day to pick up your order at DHL?”
“Shit,” Lindsey slapped her forehead, “I’ll change. Back in a few!”
“I’ll go with you!” Brad offered.
“No, no way,” Lindsey interjected, “if anyone comes, I don’t want Kayla to be alone.”
Brad knew his girlfriend’s final tone. They could argue for hours and she wouldn’t budge. He sighed. Lindsey left the pool and went upstairs… then exited the home, dressed in basics.
“What the fuck, Kayla?” Brad muttered once his girlfriend was out of earshot.
“It’s cute, huh? How she thinks I’m the same 13 year old that thought her s****r’s boyfriend was really cute and everything,” Kayla showed a wide smile.
“You can’t do this. It’s not right,” Brad shook his head.
“Do you wanna know what I think now, though?” Kayla’s expression became one of shyness. Completely unexpected.
“What?” Brad couldn’t believe she could be flustered.
Kayla half swam, half walked to him and got real close, “I don’t want anyone else to hear this, but…”
“But..?”



Kayla wrapped her arms around Brad’s torso and aggressively began to grind her pelvis against his with deep, long movements as she kissed him fiercely.
The a****l side to Brad reacted first. He put his hands on her ass, pressing her harder against his erection and kissed back… then jumped backwards.
“What. The. Fuck?!” Brad gasped.
“I saw you fuck Lindsey last night,” Kayla said, “so I think you’re gonna fuck me right now. I want that thick dick inside me.”
“Kayla,” Brad began.
“If you don’t fuck me, I’ll tell Lindsey you tried to.”
“I– Lindsey– argh,” Brad saw the plan. Of course Lindsey would believe Kayla if she claimed a pink emu fell from the sky and asked her to become a hipster.
“So. If I,” Brad didn’t try to say the verb. He was already painfully hard, “if we do this..?”
“I won’t say a word.”
“But if I–”
“I’m not listening,” Kayla had turned her back to him and pulled herself out of the pool. She nonchalantly removed her bikini. As much as his mind wanted him to stay faithful, his body was reacting immediately to the curvy yet athletic body revealed to him. She shaved, just like her s****r. But those breasts! They bounced softly and the nipples hardened in the breezy evening, “I call the shots now. I’m gonna ride you. Hop on.”
Kayla patted a lounging chair. Brad almost mindlessly hopped on top of it right after removing his swimming trunks. Kayla smiled at his manhood.
“No wonder why she doesn’t stop talking about it.”
Brad slapped his forehead, “left the condoms under the TV base.”
“So that’s where you stash them! But we don’t need any.”
“But Lindsey never…”
“Good thing I’m not Lindsey, huh?”
His heart jumped, “I have never…”
“You’ll love it. Now lay down.”
Kayla quickly straddled him and grabbed his manhood.
“Fuck. We’ll get this to fit.”
“You should try going slow, Lindsey… oh… oh, shit, this is good…”
Kayla had pressed his hardness against her entrance and sat down on it. Only half of him had gone in and she had already opened her mouth in obscene pleasure. She pulled back and Brad noticed she was drenched. Kayla was so wet, his cock was coated in a thick layer of lubrication. On the second try, his girlfriend’s younger s****r got two thirds of his cock inside. She turned around with a look of sultry determination and sat up until only hips cock head was inside her… then slowly sat down, eventually taking all of his naked dick inside her, wantonly exhaling the moment she felt his hips press against hers.
Kayla stood up, “first time bare, huh? Let me give you a view you’ll never forget…”
She looked away from him and straddled him, reverse cowboy style. His girlfriend’s s****r sat down on his cock, moaning throatily as she did so. Brad wanted to pretend he wasn’t enjoying it, wanted to tell himself he was being a reluctant blackmailed party, but watching her shapely ass descend and her extremely wet pussy taking him in was too much. Although his hands didn’t touch her at all, he couldn’t fight the moan that escaped him. She felt too fucking good. And he had fantasized, more than once, about doing this exact thing to her. He kept telling himself that since it was a fantasy, no harm was done.
Being balls deep inside her and not using a condom, unlike how he fucked his girlfriend, however…
Kayla rode him slowly, patiently. And still, Brad could tell the forbidden body getting leisurely impaled by his thickness was getting close to orgasming. Unlike with condoms, he could feel how she was getting close. He could feel tiny ridges of pleasure, instead of pressure. He could feel her growing tighter. He could feel the temperature and the texture of her skin. He could feel everything. Knowing it was wrong made it a heightened sensation, though.
Brad knew he had to get Lindsey to fuck without a condom. It felt too fucking good to ever use one again. The feeling of an unprotected pussy had no comparison. All he had to do…
Kayla was lost, staring at the houses in front of their pool, moaning every now and then, louder. She moaned so loud he was lost in her sounds and stopped thinking for a second.
…all he had to do was to get her on the pill.
Fuck. Was Kayla on the pill?
“Kayla,” Brad finally found his voice after moaning yet again, hating his body for being such a traitor.
“Mr. Defoe always peeks from his window,” Kayla nonchalantly said, “at least when he hears the pool being used. If you wonder why I dive-bombed…”
Brad tried to move as if she were going to chop his dick off, but his girlfriend’s little s****r put a hand on his chest, gently.
“Too late. He has seen me take all of this dick inside me, Brad. Oh… yeah… all. Of. It. He didn’t hear a word of… holy fuck, how does Lindsey bounce like that on this?” Kayla made reference of the wild sex Brad had had just a day ago. Lindsey was able to take his cock like a champ after a while of practice, “oh… anyway. Now we have a witness.”
Brad could tell she wanted to say more, her mouth opened and she inhaled, but she moved a little faster and no sound came out for a few seconds… then moaned louder.
“I’m so close, baby…”
Brad felt disgusted with himself. Hearing her call him baby was something he needed to hear again. He began to fuck her upwards. Kayla screamed with pleasure.
“Kayla,” Brad grunted and tried to fight his orgasm back. Kayla was too fucking tight and her pussy felt too good, however. He had but a minute or less, “Kayla, are you on the pill?”
Kayla gasped with pleasure and her body rocked, trembled as she screamed with pleasure, “fuck me, Brad! Fuck me!”
Brad moaned louder. Now everybody surrounding the house knew Brad was fucking someone. He didn’t fool himself, not grabbing her hips didn’t make him any less guilty, but he fucked her upwards faster.
“Kayla, I’m about to…”
“Cum inside me Brad! Give it to me!” Kayla definitely enjoyed it, but given the volume and the chosen words, she wanted to make sure everyone knew, “make your girlfriend’s s****r pregnant!”
Awe, horror and fascination washed over Brad when he heard himself grunt and a gob of thick cum exploded deep inside his girlfriend’s s****r’s fertile pussy.
“Yes! Fill me with cum! Fill…”
For all the show Kayla was putting, there was no doubt she did enjoy him cumming inside. The last part of the phrase was cut off by a throaty scream and her body growing tighter.
“Kayla…” Brad heard the tone in his voice. That sounded like nothing but need. He groaned as the last spurts of cum ended up deep inside Kayla’s forbidden pussy.
Kayla finally collapsed.
“Fuck! I had never cum that hard,” Kayla admitted, “I’m going to fuck you until you have no cum left.”
“Kayla… but…”
“Brad. Look at this,” Kayla stood up and he stared in admiration as her pussy didn’t close up immediately after. Cum dripped out of her, “you came so much inside me… and you have no other choice. We’re getting rid of Lindsey every now and then so we can have some privacy and you’re going to fuck me again.”
Brad didn’t even need to be told the details. He had witnesses *and* Kayla’s word against only his version. He was her new slave. He shouldn’t have been that hard thinking about it, but he couldn’t help it.
“…and I wonder what will happen if you get me pregnant..?”
Brad couldn’t hide the excitement mixed with horror. He was sure he sounded far more eager than worried when he acquiesced with a short, “you win
