Play around with John

John's POV

"Lisa, is that you? What're you doing down there?", John called out curiously from upstairs. His older sister should already be back home by now from her morning jog and he had something to talk to her about. He could hear noises coming from downstairs and thought that it must've been Lisa. Unsatisfied with getting no response, he decided to just go downstairs and speak to her face to face. Plus, he could also use a snack or two.

He could hear some more noises coming from downstairs as he made his way there. However, as he reached the living room downstairs, he could see his sister sitting on the couch lazily, leaning against one side of the couch. Her face had a weird grin plastered on it as she sipped on a glass of water. She was fully clothed in her normal running attire, a light blue tank top and a tight black leggings. Her light blonde hair was tied into a neat ponytail, her usual hairstyle for when she goes jogging.

"Why didn't you answer if you were already home?", John asked annoyedly as he took a seat next to his sister. "Oh, uh... I was just... you know, drinking some water.", his sister replied with with an oddly cheerful chuckle. "Sure...", he said awkwardly, not understanding the logic but also not wanting to press the matter further.

"Why were you calling for me anyway? Did you miss your dearest sister or something?", Lisa asked him playfully before taking one last gulp from her glass and setting it down. "Ew, no. Why would I miss you anyway?", he replied as his face contorted in mock contempt. This was a routine banter between the two siblings and he didn't really mind it that much.

"Aw... You sure you don't miss this thing?", his sister teased with a playful tone. Ah, here it is. He could tell from her tone that this was the daily dose of her teasing him. However, when he glanced to the side to see what prank she was going to pull on him today, his eyes shot wide open. His sister had pulled one side of her tank top up, flashing one of her breasts to him. He could see that she wasn't wearing any bra at all judging by the nipple poking out of the side of her chest that was still covered.

"W-what!? Lisa, what're you doing!?", John said in a flustered tone. "What do you mean what am I doing?", his sister replied as she pressed her body against his arm. The sensation of his sister's soft chest pressing against him sent a shiver up John's body, so he quickly scooted away from her. "Stop it! It's not funny!", he said in a flustered tone.

"But it is to me~", his sister winked playfully as she pulled up the other side of her tank top and stuck her tongue out. It seemed she was having some fun at his expense. Still, how could she even do something like this just for a prank? She'd normally just tickle him mercilessly at worst. But now, it's full on flirting sensually. He'd never seen his sister in that light before. Sure, she was objectively hot by his standards. But yet, they were siblings. It grossed him out to think about her in that way.

His thoughts were quickly interrupted as he could see Lisa crawling towards him. Her breasts hanged freely from her chest as they swayed in rhythm with her sensual crawl. Before he could do anything, Lisa was already on top of him, straddling him and trapping him under her.

"Quit it, sis! This is just going too far!", he reached out with his right hand, trying to pull down Lisa's tank top to cover her up. But before his hand could reach its target, Lisa's hands managed to stop him. "C'mon, this much should be fine, right? It's just some healthy bonding between siblings~", she whispered softly as she tightened her grip on John's hand.

What? Bonding? That doesn't sound like what he was experiencing at all. He needed to stop this ASAP, but his body felt weak for some reason. His mind was going blank as his face flushed red. He tried looking away and closing his eyes only to get a chuckle from his sister. "Aww... why are you looking away?", she said in feigned disappointment before adding, "Oh well, you don't need to see to enjoy this anyway~".

Grabbing his hand with a seductive smirk, Lisa slowly guided it towards her own chest. As his hand made contact with the breasts, his sister's hands **** it to move in an awkward cupping motion. "How does it feel? It's soft, isn't it?", she giggled teasingly. John couldn't help but follow along with his sister's movements. He could feel just how soft her breasts were as she continued whispering sweet words to his ears, but he dared not open his eyes.

"There, that's a good boy. Just play along and enjoy it~", Lisa sighed softly as she could feel John's hand giving in to her lead. Slowly, John's hand even started moving on its own, swept away by the comfortable feeling. Seeing the state he was in, Lisa snickered, "You know? You're so cute when you're like this~".

John could then feel his sister grabbing his other hand and leading it behind her. He was too weak to resist it and so he let his sister put his hand on her ass before being **** to feel it up. "Hm~ This part feels pretty nice too. I should've played with them too last night~", Lisa hummed quietly to herself. John didn't really catch what she said, though, as he was overwhelmed by the double combo of his sister's breast and ass.

"So, does it feel nice touching your sister like this?", Lisa asked with a soft smile. Her smile turned into a sinister grin when she saw John looking away with a conflicted face. "Not gonna answer? I'll take that as a yes then~", she continued with a teasing tone before adding, "Get ready, though, 'cause we're only just starting~".

John just shut his eyes even tighter at that comment, his feelings a contradictory mess between disgust and immoral pleasure. His hands moved on their own following his sister's lead. Before long, he could feel something rising in his crotch creating a bulge that pushed against his pants. His sister smirked as she noticed, "Seems like someone's awake down here~".

Lisa then pushed her body downwards, rubbing her crotch against John's own. He could feel his dick getting harder by the moment as his sister grinded against his crotch. Even behind two layers of fabric, he could almost picture the two genitals rubbing against each other, the imagination fueling his arousal even more.

"Mmm~ You like it, huh? You like it when I rub against you like this?", his sister hummed teasingly. Her movements started becoming more aggressive, grinding down against his crotch faster. Her breasts and ponytail shook wildly as she did so. "C'mon, just admit it. I'm not gonna be mad~", she continued as her breathing started becoming heavier.

No, this is wrong! I shouldn't be doing this with her! We're siblings, for fuck's sake! How am I going to look her in the eye after this?

The rational part of John's mind continued protesting to no avail. He was too focused feeling up his sister's body and enjoying her rubbing all over his crotch. He could feel the pleasure mounting on his brain, ready to be released. His sister's teasing words pushed him even closer. And then, it came.

"Urgh...", John groaned while gritting his teeth as he could feel himself orgasming. The semen flooded out of his erect dick, creating a wet stain on his pants. He could also feel a streak of tear pouring out of his closed eyes. He quickly removed his hands off of his sister's body and covered his face in embarassment.

His sister stopped moving as she noticed it. "Did you just... cum?", she asked slowly as her face contorted in disbelief. Her lips then curled into an amused smirk, "You did, didn't you? You seriously just came from your sister rubbing all over you!". He could then hear her laughing mockingly at him, "I can't believe this! Ahahahaha!".

Frustrated by Lisa's mocking laugh, John quickly pushed her away and ran upstairs towards his room. "Ah! Hey, wait! I'm not done yet!", Lisa called out to stop him, but he didn't listen to it. John made his way inside his room and swiftly locked the door behind him.

Mark's POV

Mark frowned in Lisa's body as he could hear the door slammed shut. "Tch... I haven't even had my fun yet...", he muttered, clicking his tongue in annoyance. Though he did manage to get his fill of messing with John, he had also managed to excite Lisa's body in the process. The burning sensation filled his body up like the night before. Lisa's body was begging to be touched and pleasured again, but the little crybaby just had to ruin it by running away.

"He could've at least had the decency to make me cum first...", he said to himself as he rubbed his crotch. He could feel the wet sensation through the tight legging he was wearing. Pulling out the legging with his hand revealed an underwear which matched the color of the sports bra. Come to think of it, he had thrown away the bra back at the kitchen as preparations for surprising John. He should probably pick that up later. But for now, he was more focused on the underwear he was seeing. Grinding his crotch against John's had left it soaked, but it wasn't enough to make him orgasm.

Thankfully, Mark couldn't feel Lisa's consciousness waking up yet. It seemed that he still had plenty of time to have his fun in her body. He could try messing with John again, perhaps he'd open the door for his dear sister? Or maybe he could just do it by himself? Or perhaps there was another way to fulfill his desire? There's plenty of options, after all...
