"Well, I guess we could start with breakfast." Jon was still starving and thirsty from cumming a fuck-ton inside Becca.
"Food sounds good. You have no idea how much I squirted all over my bed before you came over." Karyn blushed at her own words. She wasn't ashamed, but she cutely excited or giddy to tell Jon what she had been up to. As well as ashamed that she had dozed off before him last night because of it.
"It was fairly obvious where the dampness came from when I caught you playing with 'little Jon.'" Jon made a reference to her moans as he caught her.
Karyn looks beet red now. Ha! She's such a cute girl. How have I not made a move before changing us with a wish?
They walked past Karyn's parents in the hallway, who were too busy fucking each other's brains out than noticing the young adults walking past them. Karyn was smiling at Jon as they both had difficulty tearing themselves away from the scene before them. They persevered past them and giggled their way about the house. Finally, they sat down and ate with Becca. They consumed a lot more than what people ate usually. Jon immediately knew that the amount of sex that everyone had now contributed to people's fitness and metabolism.
"So how long do you girls have?" Jon asked as they cleaned up their meal. "You were sex contagious before I got here."
"We've got until noon before we cease broadcasting arousal. Our family usually only takes a day. Sorry you were traped into our sexual fervor." Becca sipped her coffee and continued typing on her laptop.
"Sounds like enough time to fill me up the same way, lover?" Karyn grinned at Jon as she twerked her heavy rump onto his lap before settling into sitting on him. His constant hardon poked and throbbed along her ass crack.
"Good, because I'll need company. I started yesterday evening, when I came over. So, the soonest I can leave is this evening." Jon remembered that his parents didn't know that he could very well be staying the night again. "Let me make a call to let my folks know. We should also let the school know why we are absent."
After they made their calls, Karyn brought out a pack of bottled protein shakes. Most families had them for when they have their mating week.
"We can fuck all night tonight before going to school the next day. Why don't we take up your parent's offer from yesterday?"
"So... you're saying mom is better than me." Karyn mock scowled.
"Yeah she's looser and doesn't faint when I rail her." Jon pinched Karyn's ass.
"Oh yeah?" Karyn laughed. "I know some guys at school who last longer than you do, pal." Jon thought about making another wish on the stone. He was thinking of warping his and Karyn's bodies with a few more wishes. Damn, this lust was strong! As long as he made them tied to the reset for the first wish they would be fine.
They giggled as they found Mr. and Mrs. Black back in the master bed. She was on top of him, her back to him as she nearly laid back onto him for support. His hands were hooked under her ass and were lifting her up and down on his dick. The loud wet slaps emanating from the room assaulted them along with the stench of sex from the night before as well as fresh raunchy arousal.
"Oh-oh-oh-fuck!" Mrs. Black noticed them first as she bounced on her husband's dick. "H-Hey kids-OH FUCK ME-freshened up yet? Oh... GOD YES, RIGHT THERE!"
"Kiddos-ugh-yeah-want to join Anna and I?" Harry looked from over his wife's shoulder. Karyn's eyes bugged out at seeing directly into her mother's cunt.
"Never seen her from this angle?" Jon leaned and whispered in her ear.
"No. Yes, but... not in this way." She couldn't take her eyes off her mother. "Look at how wet she is."
"Like mother like daughter." Jon started to tease her pussy underneath her skirt. They quickly undressed each other again.
They joined the older couple in bed, fucking and cumming, swapping partners as often as they came. They went through all manner of sexual positions, partnering double teaming but most importantly fucking. After several hours it became obvious that Karyn's parents were petering out. But that didn't stop their lust from driving them forward past their limits. Jon noted their fatigue even as he found himself being blown by Karyn and her mom at the same time. Harry plowed Karyn's ass while his hand reached around and played with her twat.
"Oh yeah, that's my baby girl. So, fucking tight. Yeah." He grunted as he thrust inside her.
Jon came from their combined lips tongues and throats. He covered their faces in his seed as they smiled up at him. They quickly switched positions, Jon mounted Anna (Mrs. Black) as Mr. Black was still plowing his daughter's bum. Eventually Jon and Harry (Mr. Black) high fived as Karyn and her mom started to make out with each other. They heard the high-five and looked behind them, but they didn't let up their act. Their pussies squeezed their cocks as they enjoyed the cheers they got from their wanton mashing of lips and tongues. The sexual thrill of being watched as they kissed made them climax. Jon and Karyn's dad couldn’t hold it any more as both women clamped down hard. Harry filled Karyn's ass at the same time as Jon spewing his own baby batter inside Anna's vagina. Jon then groped Mrs. Black's ass again as he pulled out of her. Jon noticed that Mr. Black's semen was forced out as his own seed took its place at the entrance to her womb.
Karyn pushed Jon down onto the bed to mount him, cowgirl style. Jon playfully made bull sounds as she recited a few southern phrases se knew. At least she had a good accent. She expanded her role on top of Jon in an energetic gyrating back and forth motion. Jon played with her tits, pinching her nipples and mashing her boon born bouncing boobies as she slammed herself down on his dick. Mr. and Mrs. Black were fucking. Harry was panting. Almost out of stamina. He slammed down into her pubic bone in missionary. He came in her, not long after they started fucking in their new position. They kissed and he expressed his exhaustion. He needed to refuel. Jon was going strong however, and Anna was feeling left out watching her 'baby girl' ride Jon. She decidedly sat her ass on Jon's face, mashing her dripping folds onto his nose and lips. Her dribbling sex making a shiny mess of his face. Jon attacked her nethers eagerly, drinking her juices in raw lust. Karyn forward, bringing her mouth to her mother's nipple. She sucked and groped, teasing exactly the way her mother loved most. Eventually their dyadic attack forced Anna to a screaming orgasm. Jon pushed her out of the way as she lost control of her body. She expunged much of the cum she had inside her. Her muscles giving her no choice in her climax. She lay on the bed, panting in afterglow. She quickly got her revenge, however, by attacking Karyn from below. Her hands snaked their way to Karyn's hips and held her there as she attacked her muff. Karyn screamed herself, having already been brought to climax by riding Jon had left her sensitive. Karyn expressed the same dopey look on her face that her mother had a few seconds ago. The roles were reversed in blissful fading after-sex.
Jon, not wanting to be left out, got up and stood beside the bed. He dragged Anna to the edge of the bed, her ass sticking up and her legs swaying off the side. He beckoned Karyn, who approached them giggling. She knew what he had in mind. She lay on top of her mom. Their asses stacked invitingly to Jon, who licked his lips with carnal want. He teased his entrance into Karyn's mother, the glans spreading its way over her hot love box. Then he did the same to Karyn, who grew impatient and fidgeted atop her mother in an attempt to impale herself. Jon gave her fit booty a loud slap. She gave a squeal of surprised delight and flexed her cheeks, bouncing them in meaty glory. Jon smacked his dick on her labia and then switched his attention back to her mom. Karyn whined as Anna moaned at Jon penetrating her. But Jon's hand continued to tease Karyn above. Jon loosed his seed inside Karyn's mom several times for a long period, but he never let Karyn get off. His hand constantly brought her to the brink of orgasm only to stop again. After the fifth time her mother shuddered under her from Jon filling her she grew heated beyond her own control. She got up and tried to get off of her mom. Jon slammed his hands down on her ass, They collided with the flesh with a loud slap, pressing her into her mom. Her big tits mashed into her mother's back, pleasing her nipples. He then spanked her several times, all the while preparing his dick to enter her. Then he slammed his dick all the way inside her, instantly spewing his seed inside her. His hands squeezed her ass hard as she clenched and came herself. She gave the loudest cry of pure pleasure and elation that Jon had ever heard. She was twitching from the climax she was so built up from the situation. He was stunned at the sex goddess before him. How had he not done this with her before the wish? Jon was milked dry by her depths. Her muscles contracted, clenching and releasing his prick bringing him to a secondary ejaculation. She kept climaxing, it rolled over her body with the vigor of their youth and magically sexual body. After ten minutes of them cumming non-stop they decoupled. Karyn rolled off her mom who was silently giggling to herself below.
"God you two are hot. I can't believe I didn’t do something like that with your father when we were your age." She cooed.
She sat up and gave Jon a deep kiss. Their mouths danced a mix of her and Karyn's love juices. Eventually they had to break for air, their physical activity bringing their bodies to exhaustion.
"You kids are going to be the death of me. I think I'll have one more taste before looking for Harry." She slurped Jon's dick into her mouth in one fluid movement as she knelt. She was instantly deepthroating him! She expertly brought him to eruption and greedily drank his seed directly down her mouth, savoring the bits of it that remained on his penis as her mouth sucked and glided over it's surface as it left her lips. She took extra care to drink and squeeze his cum from his penis as she returned for the last remaining drops. "Thanks for the fun you two. Stop by anytime Jon." She gave him a wink. Karyn's face was a look of happy shock.
"She really does like you. She probably wants you as a fuck-buddy." Karyn kissed Jon deeply on the lips. "Meaning we can see a lot more of each other." She was still glowing from sex. To Jon the smile on her lips looked angelic.
Karyn jumped high in the air, wrapping her arms and legs around Jon's back. Jon carried Karyn out of the room, lifting her up and down on his dick as he walked. They passed Becca in the hall, she had tied herself up on her door and awaited someone to fuck her while she was suspended and helpless. There were dripping dildos sticking out from both of her love holes on full display. She tried to call out to Jon trough her ball gag, but he looked at her with a mischievous grin and walked Karyn and him past her to leave her to uncertain fate. She moaned out in frustration and arousal at being left behind in the hallway.
Jon threw Karyn onto her own bed before pinning her beneath him. He lay atop her and pumped into her raw pussy. The friction from their constant sex was insane yet it never wore them down or felt any less pleasurable. In fact, it was growing more pleasurable. The more they came the more sensitive they got. Jon had a hard time keeping up with his lust, the heat from their bodies reflected and amplified in her bed made them sweat greater than they would normally during sex. But Jon wouldn't let up. He held Karyn down and pounded her ass with his pelvis, her cheeks were long since pink from before. Now they shone red with warmth from the impact. His tongue wound through her ear nibbling and nipping at the readily sensitive area. She was screaming out a moan and eventually they both fell asleep. Unbeknownst to them they shifted to their sides, spooning like Jon had done with Becca the night before. This time they woke several hours later, Karyn's stomach showed a tiny curve as if she ate a very large meal. She was pouting as she traced the outlines of her stomach.
"Why you didn't pump me as full as Becca."
"Your sister is fatter than you, her body allowed more expanding than yours did." Jon grinned at Karyn.
"That's not fair. She gets fat and gets more because you think she's fatter? Is that why you gave her more?"
"No." Jon pointed with his eyes to show the fresh puddle of love juices that surrounded them on the bed. "I gave you just as much see?" He paused before noting her pout and continued. "Exhibit B." Jon pulled out of Karyn and they noted the gushing stream of fresh sticky baby-batter leaking out of her before her vagina closed up and trapped most of it inside of her womb. Jon had chuckled when she had tried to stop it with her hand before her body naturally sealed the rest inside her with her muscles. Eventually got around to testing Jon to see that he had continued giving off pheromones.
"Well, want to stay here again tonight?" Karyn traced her curves along her body seductively.
"I think it already is night."
"Oh." They both blushed, giving way to grins of satisfaction.
"School is certainly going to be interesting tomorrow." Jon mentioned as they remade the bed for the rest of the night.
"Everyone is going to know that one of us blundered into the other's mating week." Karyn chided.
"I could just blame it on your mom. It really was her fault."
Karyn rolled her eyes at Jon.
"That's every guy's excuse."
"And good reason for it too." Jon cuddled with Karyn beneath the covers. "I hope you make many boys give that excuse when you are the hot milf." He kissed her goodnight and she sighed at him. She wanted to scold him again but reasoned against it. He was dangerously close to getting her fuck him all over again.
