Love Potion Lunacy 11: Mai x Kas

(Character ages are as follows: Riku, Mai, and Kas - 18; Sumire and Ichiro - Early Forties)

Mishima Residence - Friday Night - Summer

With her bag neatly packed, Mai decided to spend an hour playing through Deity of Conflict: Armageddon (God of War: Ragnarok) after her parents and brother went to bed. She could barely focus on the game, however, as she was looking forward to a fun-filled weekend at the Tanaka's Lake House. She especially couldn't wait to hang out with her girlfriend Kasumi II, or Kas as she's more commonly known.

After getting a game over, Mai took that as a sign that she should turn in for the night and get some rest. She turned the game off, put her controller back on the charging rack, and left the game room so she could go upstairs and get some sleep. On her way to her bedroom, however, she noticed that Riku's bedroom door was wide open, and she saw him trying to sleep on the floor. The young man spent the last hour trying to get in a position he was comfortable in so he could get his eight hours, but to no avail.

"What the hell?" Mai asked herself before entering Riku's room, "Riku, what are you doing?"

"Trying to get some sleep, " Riku muttered as he continued tossing and turning.

"On the floor?" Mai asked.

"You know not the horrors that went on in that bed, sis," Riku said darkly, "You! Know! Not!"

"I'm sure that bed has seen a lot worse, Riku," Mai said as she eyed her brother's bed, blissfully unaware of what went on in it earlier that afternoon.

"Not like this," Riku said, "While we were gone…mom and dad…did it in there!"

Hearing Riku say that made Mai sick to her stomach. She now understood why Riku has chosen to sleep on the floor. To both Riku and Mai, just knowing that Futaba and Yuuki 'did the deed' on one of their beds was scarier than any horror movie they had ever seen. Mai got down on Riku's level as he sat up so they could hug each other.

"You poor thing," Mai sympathized.

"Why would they do this?" Riku cried, "What did I do to deserve something like that to happen in my bed!?"

"Are you sure they actually did it?" Mai asked.

"I'm pretty sure," Riku said, gagging before he continued speaking, "I found a used condom in my trash can and…*gag*...I found mom's panties under my bed!"

Riku buried his face in Mai's shoulder, and she rubbed his back as a means to comfort him.

"I genuinely don't know why they would do this," Riku said, before realizing something, "Unless…"

"Unless what?" Mai questioned as Riku freed himself from his sister's hug.

"I'm sure you heard the noise I was making up here earlier," Riku said as he went to his sock drawer.

"Yes, Riku," Mai answered, "I heard it, mom and dad heard it, the whole neighborhood heard it. What were you even doing in here anyway?"

"I snuck Nariko into my room so we could have some 'alone time'," Riku answered, "And she brought along this!"

Riku reached into his sock drawer and pulled out the water bottle containing the love potion that Nariko took from her father's bottle. Mai was confused, and she gave a puzzled look at the '30 mL only label' that Nariko had taped onto it.

"Inside this water bottle is some kind of drink that'll increase the sex drive of anyone who drinks it," Riku explained, "Mom and dad must've snuck into my room to see why I was making so much noise when they stumbled upon this bottle, and they curiously took a sip resulting in…you know."

"Hold on, back up," Mai said, "Did you just say that whatever it is that's inside that bottle will raise a person's sex drive?"

"Yes," Riku said, "But only for an hour or so. Whew, what an hour it was, though! Nariko left me in charge of it until the next time either of us are in the mood."

"A beverage that can raise a person's sex drive?" Mai repeated in awe, "Of all the crazy things I've ever heard in life, this has to be the most far fetched thing of them all."

"If you don't believe me, why don't we take it with us to the Tanaka's Lake House?" Riku suggested, "You can test it out on Kas if you two find yourselves alone."

Intrigued and not wanting to pass up an opportunity to make love to her girlfriend, Mai accepted this offer.

"Alright, bro, you're on," Mai said, "Make sure you pack that bottle in your suitcase, though. I know it's bigger than mine."

"Doing it now," Riku said as he went over to his suitcase and packed the bottle of love potion inside of it along with a 30 mL medicine cup from the family medicine cabinet, "There we go, all packed. Now if you'll excuse me, I'm going to go down to the game room and sleep on the couch in there."

"I wouldn't do that if I were you," Mai said, feeling the urge to mess with her brother for a bit.

"Why not?" Riku asked.

Mai only smirked wickedly before saying, "They've done it there too,"

As soon as Mai made her leave, Riku fainted yet again at the thought of his parents making love on the very couch that they play video games on.

Tanaka Family Lake House - Saturday Morning - Summer

The Tanakas arrived at the Mishima Residence a few minutes after 7 A-M to pick up Riku and Mai so they could go to Lake Motosu. Futaba and Yuuki saw their kids and the Tanaka Family off as they drove away, hoping that they all have a great weekend.

The drive to the lake house was a rather pleasant one. The group of five took in the sites as they drove out of Tokyo and into the country. They listened to music on the radio, and they even had a good chat every now and again.

In their chats, they learned that Sumire is planning on retiring from gymnastics so she can be a coach at Shujin Academy when school is back in session. Ichiro, who can be somewhat stubborn sometimes, chose to keep going with his gymnastics career as he truly enjoys the sport. Kas is still trying to follow in her parents footsteps by competing in gymnastics tournaments, but she also admitted that she's showing a mild interest in wrestling. Riku mentioned how well his internship with Sunny Interactive Entertainment was going, and how there's a possibility that he'll be hired as a full-time employee. Finally, there's Mai, who was spending her summer working as a waitress at Hideyoshi's Smokehouse. But when she's not there or playing video games, she's working on a short sci-fi/horror story that she hopes to get published one day. It would be her first step towards becoming a writer, she says.

After almost two hours of travel, 9 A-M, the Tanaka Family, Riku, and Mai finally make it to the lake house. The group of five exit the vehicle, take their luggage out from the trunk, and step inside. Since Sumire and Ichiro were both gymnasts who competed in competitions, meaning they were both well off, the exterior and especially the interior of the lake house was practically palatial.

"Nice place you guys have here," Riku said as he looked around.

"Riku, you and Mai have been here before," Sumire chuckled, "Most recently for Ichiro's birthday last month."

"I know," Riku said, "But it bears repeating that list lake house is the bomb diggity! And besides, we've never stayed here overnight before."

"I know we just got here, but what are the sleeping arrangements so we can put our luggage away?" Mai asked.

"There's a master bedroom that Sumire and I will share," Ichiro said, "Then Kas has her own room, and we have two guest bedrooms down the hall, one for each of you."

"Sweet!" Riku exclaimed.

"And you'll be happy to know that both of your rooms come with a T.V," Sumire said, "So if you brought your Funtendo Switches and their docks…"

"We have," Mai chimed in before Sumire continued talking.

"...you can hook them up later tonight and have some fun." Sumire concluded.

"Auntie Sumire, you sure know how to make a guy feel welcome," Riku smiled.

"We do our best," Sumire said.

"Come on, guys," Ichiro said excitedly, "Who wants to go swimming?"

Riku, Mai, Kas, and even Sumire cheered in response to Ichiro's question. The group of five knew exactly what their first activity of the weekend should be.

Lake Shore - Midday Saturday - Summer

After bringing their luggage to their rooms, the group of five changed into their swimsuits before heading down to the lake. Sumire was wearing a pink, frilly two piece swimsuit. Ichiro was wearing brown swim trunks with a white floral pattern. Kas was wearing a light gray, sporty two piece swimsuit. Mai was wearing a frilly, two piece lime green swimsuit. Finally, Riku is wearing yellow swim trunks with a green palm tree pattern.

With the group properly suited up, and a nice lunch packed up in a wicker basket, they walked out the lake house's back door and down some stone steps that lead to the lakeshore. After laying down a beach blanket, the group wasted no time in lakeside merriment. The group spent the next two hours or so swimming in the lake, tossing a frisbee around, and having a 'water war' with the squirt guns Riku and Mai brought for the trip.

After a while, Riku, Mai, and Kas decided to swim out to a raft that was floating not far from them while Sumire and Ichiro hung out on the beach blanket and watched them. As they watched, Ichiro wrapped his arms around his wife as she sat in his lap and he nuzzled her neck and kissed her cheeks.

"What's this for?" Sumire giggled, enjoying the affection she was receiving.

"Just loving you," Ichiro answered, "Is that so wrong?"

"You're so cute," Sumire smiled as she and her husband's attention was brought back to the kids on the raft. They noticed that the three of them were talking about something.

"I wonder what they could be talking about over there?" Ichiro wondered.

Out on the raft, the Mishima kids were telling Kas about the 'love potion' that Nariko brought when she snuck into their house to make love to Riku.

"You and Nariko actually did it while Uncle Yuuki and Auntie Futaba were home?!" Kas said in shock, "Weren't either of you worried about getting caught?"

"A little, but we were living on the edge yesterday," Riku said, "Just felt like playing with dynamite, you know what I mean?"

"I still can't believe that the drink you two consumed actually increased your sex drive," Kas said.

"Well, if you don't believe it, why don't you and I give it a try later tonight," Mai said with a smirk.

"You mean you actually brought it with you?" Kas asked.

"It's been a while since we last played with each other. I figured you and I could sneak back to the lake shore later tonight and we could do our business then," Mai said, "Then maybe we could go skinny dipping afterwards to cool off."

"Oh, I like the way you think, Mai," Kas said dreamily, already excited for a romantic evening with her girlfriend, "But how are we going to sneak by my parents?"

"You girls just leave that to me," Riku said.

"Kas, Riku, Mai, lunch time!" Sumire called out to the trio.

"Race you!" Riku shouted as he jumped off the raft and swam to shore.

"Hey, no fair!" Mai shouted as she and Kas jumped into the lake and swam after him.

Tanaka Family Lake House - Saturday Night - Summer

After lunch, the group went back inside to change back into hiking gear so they could enjoy a nice hike through the woods. After the hike, and after everyone got cleaned up, they hung around the lake house, played games and talked, before getting dressed and going out to dinner. After dinner, they returned to the lake house and decided to gather around in the living room to watch a movie. By the time the movie ended, it had become nightfall and Riku, Mai, and Kas went to Riku's bedroom to grab the water bottle containing the love potion while Sumire and Ichiro remained in the living room to chat over some cocktails.

Inside Riku's room, he opened up his suitcase and presented the water bottle to his sister and her girlfriend.

"This is it guys," Riku said as he handed the bottle to Mai, "Use it wisely. Seriously, Nariko would probably kill me if you drank it all or if we lost it."

"You can count on us, Riku," Kas said, "Now how are you going to distract my parents?"

"Just watch," Riku said as he walked out of the bedroom and back into the living room, "Hi Uncle Ichiro. Hi Auntie Sumire."

"Hey there, Riku, what's up?" Ichiro asked.

"Nothing much," Riku answered as he walked up to a piano that the Tanakas had in their lake house, "I just couldn't help but notice this beautiful piano you have in the corner of the living room here."

Riku took a seat in front of the piano and uncovered the keyboard.

"Seeing this piano here got me thinking," Riku continued, "About when was the last time I played piano for you guys."

"Never," Sumire said bluntly but truthfully.

"That long," Riku said wistfully.

"Well, Riku, we didn't know you could play," Ichiro said.

"I've logged a lot of hours on Keyboard Legend (Guitar Hero)," Riku replied, "So I may know a few songs. You want to hear?"

"Sure," Sumire said as Ichiro nodded his head.

Riku turned his attention to the piano, cracked his knuckles, and started playing the piano like a man possessed. Sumire and Ichiro were utterly amazed at how well Riku was playing their piano. So amazed in fact that they started bopping the heads and tapping their feet to the rhythm.

"Nothing from nothing leaves nothing! You've gotta have something, if you wanna be with me!" Riku sang, "Nothing from nothing leaves nothing! You've gotta have something, if you wanna be with me!"

With Sumire and Ichiro thoroughly distracted, Mai and Kas poked their heads out from the hallway to see Riku's distraction at work.

"Damn, if the whole gaming thing falls through at least your brother has a promising career as a pianist," Kas said amazed.

"Not surprising," Mai said, "There was a time not too long ago when Riku was addicted to Keyboard Legend, both the console version and the version at the arcade. But enough about this, let's make our move."

With the love potion and a beach blanket in tow, Kai and Mas successfully snuck passed Sumire and Ichiro, who were still enjoying Riku's piano playing, and made it to the door that led outside.

"I'm not trying to be your hero! 'Cause that zero is too cold for me!" Riku sang, "I'm not trying to be your highness! 'Cause that minus is too low to see!"

Once Kas and Mai left the lake house, they hurried back to the lakeshore.

Lake Shore - Saturday Night - Summer

Kas and Mai successfully made it back to the lakeshore without being detected, and they laid out their beach blanket so they could sit upon it and go stargazing like they did before they became girlfriends. Hand in hand, the two girls gazed skyward and admired the moon and the stars.

"It sure is a beautiful night, isn't it?" Mai asked?

"It really is," Kas concurred, "The perfect night to be with the one I love."

Mai was holding the water bottle full of love potion in her hands, and she looked at her girlfriend with nothing but love in her eyes. She was more than ready to have a romantic love making session with her, just as Kas was ready to do the same.

"Ready to see if this drink does what Riku says it does?" Mai asked.

"As long as you're by my side, I'm ready for anything," Kas said, "But first, what do you say we get comfortable?"

"Oh, okay," Mai said.

And so the two girls started to undress until they were completely naked, and they just stared at each other for a full minute, taking in every facet of their bodies which looked beautiful under the light of the moon.

Kas had the reasonably sized C-cup breasts of her mother, some slender legs with strong thighs from gymnastics, a round and soft, but also firm, butt, and an overall athletic build. Mai, meanwhile, had B-cups that were slightly bigger than her mothers, but to Kas they were perfect nonetheless, shorter legs with reasonably sized thighs, a round and plump butt, and a slender frame. Their bodies may be different, but if there's one thing they have in common, it's that they both have clean-shaved womanhoods to admire.

Mai thought Kas looked absolutely stunning, just like how Kas viewed Mai.

"You look so beautiful, Mai," Kas said.

"So do you," Mai smiled as she grabbed the water bottle and the 30 mL cup to pour it in. Once the cup was full, she gave it to Kas, "You ready?"

"See you on the other side, babe," Kas said as she drank up the contents of the cup before handing it back to Mai so she could take her dosage.

After Mai drank her portion of the love potion, she looked over at Kas and saw that it had already started working its magic on her. She was staring at her petite body with an intense hunger, and not long after that Mai started to stare at Kas in the same way. The two girls slowly walked up to each other and started to embrace one another. Tangled up in each other's arms, the two of them started to passionately kiss, their breasts rubbing against each other. The feeling of their bodies rubbing against each other was, and always will be, indescribably pleasurable to the both of them.

Their snogging brought them back down to the beach blanket where Mai's mouth went from Kas' lips to her breasts. Kas stroked her lover's hair as she suckled away at her bosom. As she sucked at her nipples, Mai listened to Kas' moans.

"She seems to like it when I suck on them," Mai thought to herself, "But I wonder what would happen if I did this?"

And that's how Mai went from just sucking on Kas' nipples to gently scrapping the pink nubs with her teeth. It was something that they never tried before, and she was hoping that Kas liked it. Fortunately, the increased volume and frequency of Kas' moans told Mai that she absolutely loved it. As Mai continued her oral assault on her breasts, Kas was trying to think of ways that she could give back to her. With no other idea, Kas reached down towards Mai's pussy and started to slide her fingers against her labia before sliding her pointer and middle fingers in and out of it. Almost immediately, Mai began panting and mewling as her body quivered in pleasure.

"That's right, baby girl," Kas cooed, "Let those moans out. I want to know how much you're enjoying this."

"I can do that too you know," Mai said as she continued nibbling on Kas' breasts.

Mai moved her hand down Kas athletic body until her fingers rested upon her clit. Mai started to rub it, softly at first before picking up the pace. With her breasts and now her pussy getting attention, Kas was becoming fuzzy headed and losing herself in pleasure. After a while, both girls' nethers were completely soaked, and the young scarlet haired gymnast looked at her orange haired lover, wanting a change of pace.

"Please," Kas cooed, "Let me taste you."

"Only if I can taste you," Mai purred.

"Deal," Kas smirked.

Kas laid down on her back as Mai got on top of her. Kas was staring directly into her girlfriend's moist tunnel just as Mai was doing the same. Without wasting another second, the two girls began to feverishly eat each other out in a sixty-nine, Kas massaging Mai's rump as Mai rubbed Kas thighs.

No words were shared between the two, only delirious pants and moans. Kas' tongue lapped her tongue around Mai's labia and licked up and down her slit, making sure to get her clit in the process. Above her, Mai was rhythmically wagging her tongue across Kas' clit and sliding her fingers in and out of her pussy.

It was practically a race to see who would blow first, and neither were willing to go without a fight. It wasn't until Kas started to suck on Mai's clit that the orange haired girl started to slowly let go. Mai's body started to shake as an orgasm crashed through her, gushing out of her pussy and onto Kas' face. A few seconds later, the same thing happened to Kas herself, her own juices squirting out of her snatch and staining the beach blanket beneath them.

Mai got off from atop of her girlfriend and they kissed again, their tongues laced with each other's vaginal fluids. The two girls got a good taste of each other, and the mixture of their juices tasted sweeter than any candy.

"You ready for the main act, baby girl?" Kas asked as she broke the kiss, which lasted quite a while.

"Ready when you are," Mai smiled.

The two girls faced each other and maneuvered their bodies until their legs were wrapped around each other and their pussies were pushed up against each other. Then they started to move, and immediately waves of pleasure washed over the two girls as they started scissoring.

They began moaning wantonly, hoping that Riku's distractions from inside the lake house were loud enough so Sumire and Ichiro wouldn't hear them.

Kas and Mai groped their own chests to add to their building pleasure, and they stared into each other's eyes as they continued their act. Their crotches started to get covered in their love juices as they picked up the speed of their tribbing. Again, the two of them held back their orgasms for as long as they could, but they were fighting a losing battle as their respective needs for release grew to a fever pitch.

"Kas," Mai panted, "Can't…hold on!"

"Me neither," Kas groaned in reply as her right hand gripped onto the beach blanket tightly, "Let's take it together!"

A few more seconds of frantic rubbing, and both Kas and Mai moaned skyward as they both came hard. When their orgasms passed, the two girls were laying next to each other on the beach blanket and cuddling, the love potion having run its course. They spent the next couple of minutes catching their breath, the only other sounds being the gentle waves of the lake, the chirping of crickets, and the croaking of frogs.

"So, Kas," Mai finally said, "Do you believe mine and Riku's claims now?"

"Yeah," Kas said with a blissful sigh, "That drink is the real deal. No joke, that might just be the best sex we've ever had."

"I'll drink to that," Mai said.

"We went at it pretty hard," Kas said, "You still have enough energy for a quick skinny dip?"

"I thought you'd never ask," Mai smiled.

Mai and Kas, got up from the beach blanket and ran into the lake. They spent the next few minutes frolicing beneath the moonlight, swimming around, getting into a playful splash fight, and embracing each other in the lake.

This was definitely a night neither of them would forget anytime soon.

Tanaka Family Lake House - Saturday Night - Summer

After a while, Kas and Mai dried off and put their clothes back on before wrapping up their beach blanket and heading back inside.

When they re-entered the lake house, they found Riku still distracting Sumire and Ichiro. Only now, he went from playing songs on their piano to blasting some pop music. Riku and Sumire were bopping to the beat and watching as Ichiro randomly started twerking to the music, disturbing Kas and Mai.

"Cover your eyes, Mai, no one needs to see that," Kas shuddered.

The two adults and Riku finally noticed Kas and Mai's presence as they continued dancing to the music.

"Hey, girls, where have you been?" Sumire asked.

"Just figured we'd go out and get some fresh air," Kas said, "It's a beautiful night."

"Oh, alright," Sumire said, not questioning anything else.

"Come join us, girls, we're having us a good old fashioned dance party!" Ichiro said.

"As long as you promise not to twerk, dad," Kas said as she and Mai joined in on the group's dance party.

"Who here at the Tanka Family Lake House looking to have a good time tonight say, 'Hey!'" Riku shouted.

"HEY!" Sumire, Ichiro, Kas, and Mai shouted out.

The group of five partied until midnight when Sumire and Ichiro finally went to bed. Riku, Kas, and Mai stayed up and they hung out in Riku's bedroom where they talked and played video games, over snacks and soda. A little after 3 A-M, Mai and Kas left Riku's room so he could get some sleep.

After they left Riku's room, Kas invited Mai to come sleep with her in her room, and the two of them just laid under the covers, the A/C cranked up, and fell asleep in each other's embrace.
