The busty beauties went out back to the hot tub to relax themselves, ease their swollen nipples, pussies and tongues and most importantly to ogle each other's luscious bodies. The hot tub was massive, about 20 feet in both length and width. Still, the girls huddled close to each other as they lowered themselves into the hot water, moaning with ecstasy. Something they both knew they'd be doing a lot more of during their stay here.
As they settled in, they stared into the bright blue sky, their nipples extending as the hot water gave them goosebumps. Akeno reached out and began playing with Rias's soft, flowing, red hair. Rias closed her eyes in pleasure, showing clear enjoyment of the sensuality of the gesture. As Akeno ran her friend's locks through her fingers, she reached out with her other hand and started to knead Rias's bouncy, F cup breasts, pinching her nipples and making her moan.
"We're supposed to be on break." Rias said, trying to sound more annoyed than she actually was.
"I can't help it, babe." Akeno said. "Even I can't keep my hands off a body like yours"
"Save the kissing my ass for when I win." Rias teased.
"Just out of curiosity..." Akeno began. "What do you plan on doing with Issei if you do win?"
"Well, I'd have to punish him for letting you suck his dick when he knew it was supposed to be our night." Rias answered. "First, I'd tie his hands and feet to a chair, then I'd bring you in and start dominating you right in front of him."
"Watching us play with each other is supposed to be his punishment?" Akeno asked.
"Ah ah, not play around." Rias corrected. "I'll be dominating you and you'll just be going along with it. And remember, his hands and feet will be bound, so he can't gratify himself. I'll also pry his eyes open and force him to watch until he gets blue balls. It will be torture for him"
"Damn, girl." Akeno said as she continued to fondle Rias. "You can be pure evil sometimes."
"You love it, you slut." Rias said. "So, what will you do with him if you win?"
"Not as creative as yours, but I think I'll just bring you in with us, take a strapon dildo and he and I will DP you." Akeno explained.
"Oh, you dirty slut!" Rias teased.
"I'm still working out over who gets your mouth and who gets your pussy." Akeno teased back. "Which would you like?"
"Surprise me." Rias said as she reached out to play with Akeno's wet, raven hair.
"So..." Akeno began. "How would you dominate me as Issei watches?"
"Well, I'd set the mood immediately by shoving your face into my cunt and making you eat me out." Rias describes.
"Oh, you mean like this?" Akeno said as she grabbed Rias's head and forced under the water and into her crotch.
Rias was taken by surprise but immediately began lapping at her rival's snatch. Luckily, devil's can breathe underwater for insane amounts of time. She could hear Akeno moaning as she pleasured her best friend, ramming her tongue in and out like a small, wide, wet penis. She kept this up for about three minutes until she felt Akeno gyrate in orgasmic motion. Akeno finally let go of Rias's head and the redhead came back out of the water, dramatically flipping her beautiful mass of red hair back and splashing Akeno.
"No." Rias said as she wrapped her hands around Akeno's long, black hair. "It'll be more like this." She then pulled her rival's head underwater by her hair and forced her mouth onto her pussy in revenge.
Akeno managed to find Rias's clit with her tongue even underwater. She was an experienced pussy eater after all. She twirled it with her tongue, lapped at it and sucked on it, even biting it at times. Rias moaned loudly, enough for her submerged best friend to hear it underwater. After lapping at her clit for around three minutes, Rias's came. Akeno recognized those subtle body movements and Rias's orgasming voice anywhere. She ascended out of the water, flipping her flowing hair and splashing Rias in return, breathing heavily. As the two babes caught their breath, they stared at each other in bliss before coming together, their gigantic bazongas pressing together and their nipples stabbing into each other as their fingers played with the other girl's beautiful locks.
"So, how else would you dominate me?" Akeno asked. Her curiosity still not satisfied.
"Well..." Rias began as she grabbed Akeno's waist and pulled her in closer as she whispered in her rival's ear. "I'd tease him with a little bit of this."
Rias licked at Akeno's ear, making her best friend close her eyes in ecstasy. Rias lowered her hand to Akeno's plump ass, squeezing and kneading it while her other hand grabbed a handful of raven hair and began pulling. Akeno moaned as Rias violated her. For a brief moment, she considered losing on purpose just so she could experience this again but her competitive spirt slapped that out of her. She was determined to fuck her friend into submission for Issei's enjoyment and then to DP her along with him.
Akeno pulled Rias out from licking her ear and rammed her tongue into her rival's mouth. The sex rivals made out passionately, moaning as they sucked each other's tongues and used their hands to play with each other's boobs, asses, pussies and hair. They licked each other all over, relentless in their conviction before they finally separated. They smiled at each other before Akeno took her tongue out and licked Rias from chin to forehead. Rias giggled and did the same, licking Akeno but when she reached her mouth, she licked her friend from side to side, tasting her flawless skin. They kept this up for a while, trying to one-up each other with their little licking contest until their tongues met again but this time stayed out of their mouths. They pressed their tongues together, slurping and tasting each other, sometimes wrapping their lips around their rival's tongue and sucking hard like they were blowing their boyfriend.
"So, even though I was mad, I'm curious..." Rias began. "How were you blowing Issei?"
"It went something like this..." Akeno said as Rias stuck her tongue out.
Akeno began licking around Rias's tongue, bobbing it and pushing against it. Rias very much enjoyed this, knowing her tongue represented her boyfriend's dick. Akeno finished lapping at her best friend's tongue.
"Girl, you call that dick sucking?" Rias taunted. "Let me show you how a real woman pleasures her man"
Akeno stuck her tongue out and Rias immediately wrapped her lips around it and sucked it with vigor. Akeno giggled a bit as this actually slightly tickled. She didn't even know that the tongue could be ticklish. Rias moaned passionately as she almost swallowed Akeno's tongue, occasionally stopping her sucking to lap at it with her own tongue. After a while, she pulled back and the girls were left moaning again. They were soaking wet and not just because of the hot tub, so they rushed towards each other and began making out again while their hands groped and pawed at everything they could.
Eventually, they realized that they were close to cumming again. They already made each other cum once with their underwater cunnilingus and they mutually decided to save the rest for the competition. They also decided that breaktime was over and it was best to get out of the water before they start to prune.
"So, what's next?" Akeno asked.
"Well, your talk of DPing me got me hot, so how about a strapon contest?" Rias offered.
"Oh, sounds like fun." Akeno said.
"We each get to fuck the other with a strapon." Rias explained. "We set a timer, which will stop when the girl getting fucked cums. Whoever takes longer to cum will win."
"I thought this contest was all about giving Issei a show." Akeno said.
"It is." Rias explained. "But that doesn't mean we can't test each other for our own competitive spirit.
"Alright, slut! Bring it on!" Akeno proclaimed.
"Let's fuck!" Rias declared. "I even have strapon colors to match our hair."
"Ohhh..." Akeno purred excitingly.
