Prompt: They'll Never Know Ch. 2 (Digimon)

Summary: The fun continues at the beach for Mai, Izzy, and Tai. Tai and Mimi continue to have fun behind Izzy's back, not knowing the computer geek actually enjoys the fact his girlfriend is cheating on him. Includes: Netorare

---

Izzy, Tai, and Mimi basked in the light of the morning sun as they walked along the sandy shores of the beach. It was a beautiful day, with a bright, blue sky above them, free of any clouds. The gentle breeze carried the sound of the ocean’s waves quietly crashing against the sand and the strong aroma of saltwater. 

The young computer expert was usually more a fan of the indoors, but he had to admit, the setting was nice. Of course, even though he enjoyed the scenery, he still caught how his girlfriend and best friend acted around each other. 

“You look good in that bikini, Mimi,” Tai commented.

“Oh, this old thing? It’s just something I threw on… You really think I look good in it?”

“Hell, yeah. You look gorgeous…”

“Oh, you sweet-talker, you. I haven’t worn this bikini in years… Honestly, it feels pretty tight,” Mimi moaned, pretending to whine in pain from her clothes.

“Need help stretching it out?” Tai asked, a lecherous grin on his face. 

Izzy had to fight back the urge to smile. He couldn’t believe the two thought he was ignorant to not pick up on their flirting. He was almost offended. Almost. 

Rather than put an end to the two’s game, Izzy encouraged it. He didn’t outright tell the two to continue, after all, part of the fun was keeping things secret. Mimi and Tai thought their relationship was a secret, while Izzy had a secret enjoyment of watching the two flirt and fuck.

“You probably don’t want to do that, Tai. Might accidentally tear it off,” Izzy commented in his most deadpan, unamused tone. The secret lovers shared a look, as if shocked that Izzy was even paying attention, before he caught their mutual smile. 

“Oh, I wouldn’t want that,” Tai chuckled.

“Y-yeah. I’d be so mad if Tai tore my top off,” Mimi huffed, pouting and puffing her cheeks as a scarlet blush was painted on her face.

“Seriously. That kind of behavior deserves serious punishment,” Izzy muttered, just loudly enough for the two to hear.

They did, and Izzy was practically pouring gasoline on the fires of lust each had in their soul. Tai wrapped an arm around Mimi, pulling her close so that their bodies were pressing together. 

“Hear that, Mimi? You might have to punish me if I do something stupid…”

“You’re right, but what kind of punishment would be appropriate for you such a naughty boy?” Mimi moaned, licking her lips as she and Tai slowed their walk just a bit. They were right behind Izzy, making it hard to watch the two, but he could still clearly heard them.

The redhead pretended he was distracted by something else as he heard the distinct sound of Tai’s lips on his girlfriend’s. Mimi moaned under the pressure as Izzy fought to keep his lips flat and his dick flaccid.  

“I mean, I can think of a few good punishments,” Tai grinned. “Maybe I should spend some time in the torture room you and Izzy have. Bound and gagged.” What he was saying was clearly becoming more sexual as Izzy watched them from the corner of his eye. Tai was slipping a hand behind Mimi, slowly moving it down to stroke and squeeze her rear.

“Oh, come on, Tai! We don’t have a torture room, yet.” The two giggled, rubbing against one another as Izzy heard the distinct sound of a pair of lips parting from skin. They had just shared a quick kiss, thinking he wasn’t looking. They broke away with a quiet pop, before they continued talking.

“What I do have, though, is an idea.” Mimi wrapped her arms around Tai’s body, squeezing it tight as she struggled to act coy. “I heard there’s a cave nearby. I wanted to try exploring it!” she beamed, and judging from her tone, Mimi might have really had no ulterior motive.

“Oh, yeah! I heard about it too from the locals. You can only reach the cave’s entrance by swimming to it,” Tai added.

“If it requires that much effort, you can both count me out,” Izzy quickly declared. While his girlfriend might have simply wanted to explore the cave, he knew what she really wanted. If he simply ‘chickened out,’ Mimi and Tai would see the cave as their next chance to full around.

The genius was right, of course, and Tai and Mimi shared a look as they smiled at each other. They were both thinking the same thing as their hands squeezed each other’s, and the two accepted Izzy’s choice with little arguing.

It was easy for Mimi and Tai to swim to the hidden cave, and surprisingly enough, it was also easy for Izzy to follow them. A computer geek he might have been, but Izzy was a surprisingly strong swimmer when properly motivated. 

He followed the two at a fair distance, watching them walk onto dry land and into the mouth of a large cave. He followed them every step of the way, hiding just out of sight. There was a quick pace to all three of their hearts, a rush of excitement for Mimi and Tai as they reveled in their ‘privacy,’ and Izzy watched the show begin. 

Izzy stood at the entrance of the cave behind a large rock, hiding as he saw the two standing within the cave. They were only a few feet away, close enough to the entrance for natural light to illuminate their bodies. They had no idea he was there, watching them. 

Somewhere in the back of his intellectual mind, Izzy thought of their relationship in a purely scientific manner. A mutualistic, symbiotic relationship that benefitted all parties. He was happy to see Mimi get what she wanted from Tai, while Izzy was free to enjoy the show and feel his own type of sinful pleasure…

“Mmm, Tai…” Mimi moaned the young man’s name, shaking as he kissed and sucked on her neck, leaving little, red marks. “Careful… It’s hard hiding your hickies, silly,” she giggled.

“Sorry. Can’t help myself. I love leaving my mark on you.”

The two continued to kiss, this time pressing their lips together. They nibbled on one another’s lips, their tongues slipping out to lick and wrestle with one another. Mimi’s hands gently stroked the brunette’s chest as the young man kept his hands on her ass, grinding their bodies together as she felt his erection through his swim shorts.

Mimi licked her lips as Tai smiled at her. “Mmm, someone’s happy to see me.”

“Can you blame me? You’re gorgeous.”

“You sweet-talker, you,” Mimi giggled, licking his cheek, before her hands hooked his shorts, but Tai stopped her, catching her hands in his. She blinked, looking at him in confusion. Both she and Izzy hoped that Tai wasn’t having second thoughts.

“Hold on. I want to repay the favor this time.”

“Oh?” Mimi was blushing, and she giggled as she released his shorts. “Is that so?” The brunette caught the string holding her bikini bottom together, gently tugging on it, teasing her lover. “You’re quite the gentleman, wanting to treat a lady like that.”

“What can I say? I’m pretty chivalrous,” Tai chuckled. 

Mimi pulled on the string, and her thong fell to the ground, laying by her feet. She then laid down, opening her legs as both Izzy and Tai saw her naked, moist pussy. The beautiful brunette licked her fingers, before using them to spread her slit. 

“Here it is.” She was blushing, breathing heavily as Tai laid down on his stomach, laying his face between her legs. Mimi continued to shake with pleasure, and she shuddered as Tai rubbed his nose against her clit. “S-stop teasing me!” she pouted, and he just laughed in response. 

Izzy watched his best friend, Tai, going down on his girlfriend. He listened to Mimi cry out as Tai began to really pleasure her pussy, licking and kissing her moist folds. The redhead sat on the ground, breathing just as heavily as his girlfriend as he slipped a hand under his shorts. His dick was already hard, and he gave it a slow rub as he pulled it out from under his clothes. 

He watched Tai orally pleasure his girlfriend, all while he was hidden, just out of sight of the couple. 

Meanwhile, Tai was doing everything he could to pleasure Mimi. He was gently nibbling on her pussy, before opening his mouth to lick at her body. He tasted her sweet juices, and listened to her even sweeter moans as she combed her fingers through his hair. 

What Tai might have lacked in expertise, he more than made up for with passion. His tongue darted in and out, smacking against her pussy, before flicking her sensitive clit. The brunette’s hands slowly crawled up her body, resting on her large breasts. He gave her nipples a quick pinch, before kneading them like soft, soft dough. 

“Oooh, fuck!” Mimi screamed, quivering under his lips and tongue. “M-Meiko is a lucky girl, Tai,” she commented. “That is, she would be if you had the guts to ask her ou-ahhh!” 

That caught Izzy’s attention. His eyes widened, and for a moment, his hand froze, gripped tightly around his dick. Did Meiko know about Tai and Mimi? It was one thing for them to be doing this behind Izzy’s back, Izzy loved the show, but Meiko? 

The young woman had a crush on Tai. Everyone in the group knew that. In fact, Izzy was sure even Tai and Meiko knew each other’s true feelings, yet neither seemed ready to act on those feelings. The computer whiz swallowed spit down as he peeked further out from behind his rock, watching the two. Tai pulled his head out from Mimi’s womanhood, panting as he stared at the gorgeous woman. 

It looked like she was blushing. 

“W-what’s that supposed to mean?” he grumbled. 

It was almost amusing seeing the usually confident man reduced to a blushing mess. He avoided Mimi’s eyes as she giggled.

“Oh, nothing. Just that she’s going to have an amazing time sleeping with you. If you ever tell her how you feel, that is,” she teased. 

Tai let out a grumpy groan, before he brought his head down. He used his tongue to smack and lick her pussy, earning more loud moans, but this time he brought a hand to her pussy as well. He began to finger Mimi, thrusting in and out with two digits as she cried out.

“Ahh! Oh, oh, r-right there!” Mimi shuddered, squeezing her eyes shut as she moaned. “Fuck, you’re amazing, Tai. I-if you keep that up, I might just help you with Meiko. Maybe even convince her to join in on our fun…”

That got both Tai and Izzy to freeze, and a similar feeling consumed them. Lust and desire filled their minds as they both worked faster. Tai kissed and gently nibbled on Mimi’s pussy, all while his fingers penetrated her and his other hand rubbed her clit with his thumb. Meanwhile, Izzy was pumping his cock faster and harder, squeezing his eyes as he and Mimi came together.

Just the thought that Tai would be fucking both Mimi and Meiko was… something else. It turned Izzy on more than he thought possible, and his legs trembled as he came onto the floor, spilling his seed onto the sand, creating a small puddle of semen just a few inches from him.

Mimi wrapped her legs around Tai, pressing his face against her wet cunt as she came, spraying his mouth with her juices. She bit her lower lip, trying to keep from screaming, but her cries eventually broke through. She could barely contain herself as she came, hitting her climax in one, beautiful, perfect moment.

It felt so good, and Mimi’s body went limp for a moment as she took slow, deep breaths. 

“Ooh… Maybe I should talk about Meiko more…”

“You… you really think you could convince her to join us?” Tai asked, lifting himself up from her pussy. 

Mimi giggled, smiling at him. “I can be quite convincing, Tai. You know that. Course, I might get annoyed if you keep talking and asking about Meiko. I just might get jealous,” she teased, winking at him.

Tai just chuckled, leaning down to steal a kiss. Izzy was shocked that Mimi kissed back without any hesitation, moaning as she tasted her own juices on Tai’s lips. The two continued to kiss, leaning into each other as their tongues fought, smacking against one another. 

The two finally broke the kiss, and Mimi moaned as she licked her lips. “One thing’s for sure, even after you and Meiko get together, I hope you and I can still be ‘friends.’” The words ‘with benefits’ weren’t spoken, but all three had the same thought. “I refuse to give up your cock… Maybe she can learn to share.”

As she spoke, Mimi began to adjust her body. Tai leaned back as the woman got on all fours, hands and knees, and offered her soaking pussy to her friend. The message was clear, and he obeyed, getting up to fuck her doggy style.

“You two will probably end up with a long distance relationship, right?” Mimi pouted, only to shudder and mewl as Tai’s dick rubbed against the entrance of her pussy. He rubbed the tip against it, teasing her as her legs quivered. “Ahh… P-please, don’t stop fucking me...!” she begged. 

Hearing her so desperate for his cock turned both men on. Neither could quite catch their breath, and Tai let out a low moan as he pushed inside of Mimi’s pussy. No matter how many times he fucked her, he was still amazed at the way her cunt would massage and stroked the length of his dick.

Izzy began to pump his penis again, stroking and rubbing it as he struggled not to moan too loudly. Watching the two go at it was like watching a couple of artists at work. It was amazing, and he shuddered as he already felt ready to cum. He fought it as long as he could as he kept jerking himself off, masturbating to the sight of his girlfriend being fucked by his best friend.

Tai pushed until his entire penis was inside Mimi, then he began to pull out, only to thrust forward again. He did this again and again, each time sapping some of Mimi’s strength and reducing the alluring brunette into a melted pool of pleasure. Her arms gave out, and she was face down in soft sand, moaning loudly as Tai continued to fuck her.

He held her hips in his hands as he slammed into her, his balls slapping against her skin as she mewled. “Oh, fuck… You’re so big, Tai!” She bit her lower lip, barely suppressing a moan. Mimi’s eyes rolled into her skull as she gave in to the pleasure, doing her best to meet his thrusts, but it was clear who was in control.

“Meiko is going to away a lot, isn’t she? So you’ll still have plenty of time to come over and f-fuuuck! Fuck me, right?!” 

“Maybe, but only if you’re good. Maybe send some pics my way when Izzy isn’t looking.”

“Y-yes! I promise! Ah! I’ll be a good girl, just as long as- ahh! As long as you fuck me!”  

The two kept at it, their bodies slapping together as Izzy closed his eyes. He squeezed his dick, wrapping his fingers tightly around it as her pumped his cock faster and faster. His mouth fell open, quietly panting as he listened to the two fuck. 

Tai spanked Mimi’s ass a few times, spanking the naughty woman until her ass was red. Mimi’s pussy squeezed tightly around his shaft, squeezing and massaging the length of his cock. He leaned forward, pressing his chest into her back. Their bodies clung to each other as their sweaty bodies were squeezed together.

Izzy saw the signs, and he tried his best to match their timing. Tai came first, placing his hands on Mimi’s tits and groping them, digging his hands into the large boob flesh. He came with a loud moan, filling her with his semen, deep into her womb. He unloaded into her, tainting her body with his seed as she quickly followed.

Mimi came, quivering on the cock. She was impaled on it, yet she still wanted more. Her eyes rolled into the back of her head as her mouth hung open, tongue sticking out as she came. Her womanhood clenched tightly, milking the dick for as much cum as it could get. Her body was a shaking, quivering, mewling mess as she drowned in a sea of pleasure. 

Her boyfriend came with her, spilling more of his seed onto the ground as he bit the inside of his cheek. He barely held back a moan as he shot his seed onto the ground, adding more to the pool of semen he had inadvertently created. 

Mimi and Tai were laying on the ground together, adjusting their bodies so they were both on their side. Both were panting as Izzy smiled at his two friends, quickly leaving them where they were as he returned to the mainland. 

The young couple laid together for a few minutes, before they pulled apart and stood up on shaky legs. They quickly began to dress themselves again, Mimi moaning as her bikini bottoms pushed Tai’s cum against her pussy. Once both of them were dressed, they started walking out of the cave. 

They made it a few steps, before both stopped.

“What’s that?” Mimi asked, pointing at a pool of a white liquid on the ground. Tai followed her eyes, frowning at the sight of the small pool.

“It… it looks like-” He glanced down at his crotch, thinking of his own cum. He didn’t speak his mind, only shaking his head as he wondered if he was right, and if he was, who left it there...

“I don’t know. Come on, let’s get out of here.”

Mimi nodded her head, following Tai back to her boyfriend. The two brunette’s hands were linked as they walked, neither thinking any more of the puddle of cum.
