NO POV
"Okay you guys that's enough resting and recharging." Erza giggled looking at the final two teams as she sat on her throne like spectating chair "Let's get this Fuck-Off started! The rules are simple, you're gonna fuck...fuck...and fuck some more till you just can't go anymore, I wanna see the best you have to offer, positions, endurance and all-around sexiness. When a winner is clear I'll call it, now get to work."
"HMM!" the two couples started making out right away, rubbing and squeezing each other to get started.
"I hope you can keep up Cana." Lucy moaned as Natsu sucked on her neck.
"Fufufu." The olive-skinned beauty said pumping Gray's cock "There's no way I'm gonna lose."
"OHH NATSU!" Lucy gasped as her pink haired lover started to kiss and suck on her tits, her strong lips working on her tender flesh "Feels so good."
"Lucy." He hummed back as she stroked his cock a bit "All this sex today, it's got me so hot and hard."
"Just how I like it." Lucy giggled.
Meanwhile near them Cana was on her knees slobbering and sucking off Gray.
"Gray I love your huge thick cock." Cana cooed looking up and her muscly lover "But..."
"But what?" he asked.
"I want it inside me." She whimpered.
Cana jumped into Gray's arms and let herself get carry fucked, his thick rod plunging deeper into her.
"They're doing stuff like that already?" Lucy pouted as she used her oversized breasts to pump Natsu's man meat "Fine!"
"Aww." Natsu huffed when Lucy stopped pleasuring him.
"Natsu~" Lucy leaned on a tree and stuck her ass back "Fuck me!"
Natsu just smiled his usual grin as he got behind her and pushed his cock into her tight snatch.
"YES~" Lucy let out a long groan as her walls spread to take in Natsu's cock.
Natsu let out his usual grunt of pleasure as he started thrusting into Lucy's pussy. With each of his hip thrusts and pumps her juicy ass smacked against his hard abs. The heat on the island already had the two lovers getting sweaty and sexier than they were before.
The two couples kept on fucking, but they weren't the only ones getting to enjoy this sight, the rest of the guild was cheering them on.
"Fuck her good Natsu!" Wendy cheered.
"Man I wish that was me." Lisanna moaned shimmying in place "I'd be so hot to just get fucked in front of everyone like that."
"Saying such naughty things Lisanna." Mira giggled hugging Lisanna from behind, her sister's head nestled into her soft bosom.
"Mira~" Lisanna hummed as her sister kissed her while rubbing her ass, their tongues twirling.
"Whoa that's hot." Wendy gasped as Mira slipped a hand into Lisanna's bikini bottoms and started fingering her, pinching her clit and labia.
They weren't the only one's getting it on as well. Erza was still supposed to be judging but watching the others get their fuck on made her want to as well, and as master she deserves to fuck who she wants when she wants too.
"You both let your partners down, so now I need to make sure you know how to be good boys." Erza smirked as she stroked off both Elfman and Gajeel.
She was still seated on her throne watching the contest as the manly men stood by the sides and got jerked off.
"You two should be paying attention to Natsu and Gray." Erza said kissing both their dick heads "You might actually learn something that helps pleasure your lovers."
The pumping of her arms made Erza's breasts wobble softly, seeing those monsters moving was enough to get both her lovers to blast her in the face with some thick cum.
But still two more people were watching, not members of Fairy Tail that had snuck on to the island with the intent of ambushing them only to be shocked by what they were seeing. There was an older, curvier woman named Ultear and a younger, just at the brink of puberty aged girl named Meredy.
"What is this...?" Ultear said in a state of shock.
"Ultear is that Fairy Tail?" Meredy asked "What are they doing?"
The young pink haired girl was blushing mad, she wasn't ignorant of sex but she'd never actually seen it. The sight of Gray and Cana going at it like two dogs in heat awakened something in her young body, a heat running through her as she squirmed in discomfort.
"I feel so...HMM!" Meredy squirmed, her panties soaking with her juices.
"Meredy!" Ultear gasped seeing how her "daughter" was reacting.
Still Ultear couldn't really blame the girl, these people were like living wet dreams.
"We need to get out of here." Ultear grabbed her hand.
Later
The Fuck-Off continued till sunset, a good handful of hours passing as the couples going at it the entire time with not a single moments rest but now the end was starting to get closer, both teams looking exhausted, sweaty and covered in cum.
Both girls were laying on their backs as their lovers plowed them from on top.
"Oh Natsu I'm so close!" Lucy screamed, her tits shaking around "Cum with me again!"
Natsu hummed back and started thrusting even faster.
"GRAY!" Cana screamed, her fingers digging into the ground as she lost it "FUCK!"
"UGRH!" Gray groaned at her sudden orgasm and tightness, unable to hold back he blasted her full of cum yet again.
"HMM!" Cana moaned a bit as Gray passed out on top of her "That's it...no more..."
"I think that's it!" Erza announced "Natsu and Lucy are the winners and our new S-Class Mages!"
"We did it Natsu." Lucy kissed him.
"Lucy!" he groaned cumming inside her yet again to savor their win.
