During their stay in UK, Gust Tumbleweed was playing his guitar when he saw Val Thundershock passing by.

"Hey Gust," Val greeted him.

"Hey Val, you did an awesome guitar solo in your song," Gust complimented her.

"Really?" she smirked at him.

"Yeah, it's like the ride through the mountains of Argentina," he said.

"Arigatō, Gust," she thanked him.

"Hey Val, are you and Gust talking together?" Rose asked her when she noticed that Val had been blushing.

"Yeah, you tiny bitch," Val answered. "We're just talking about our guitar playing."

"You two are having fun together," Rose said.

"I see you two have grown so close over the years," Poppy added when she appeared to them.

"Yeah, we were becoming close but just as friends," Val denied.

"We started out as friends but we grew closer than ever," he blurted out.

"Just like me and Branch," Poppy said.

"So did me and Billy Reverb," Rose added. "You don't need to deny it."

"Thanks guys, and besides, my mom named me Valentina because she is from the Philippines and dad is Japanese," Val said.

"Wow, no wonder you are hot, just like Rose herself," Poppy teased.

"Alright, alright! Keep your fucking compliments for yourself poptits," Val smirked at them.

They went to work on recording their songs for their albums and practicing their songs for the concert but Val was thinking of something slutty whenever she saw Gust around. Gust went to Holly Darlin' in order to ask something.

"Holly," Gust stammered.

"What the fuck do you want, Gust?" Holly asked him.

"Well, I wanna tell you about Val," he said.

"Ok, what is it?" she asked again.

"Val and I grew closer during the first half of the tour," he said. "Can you tell me how we can......you know."

"You mean, take the next steps in your relationship?" she asked him.

"Yeah," he gasped.

"Well, hard rockers are into sex," she answered. "So go ahead and fuck her."

"Whoa, that is deep," Gust gasped. "I dunno what she likes when it comes to sex."

"Go and invite her to your room and you'll find out," she said.

"Thanks," he thanked her.

When lunch came, Val was eating a bowl of rice and tonkatsu with Holly Darlin', Rose, and Poppy when they saw Gust passing by.

"Val, check out Gust's muscles," Holly gasped.

"Nahm that's just not attractive," she dismissed it.

"Stop denying it, he looks like a jacked little cricket," Rose whispered.

"Oh yeah, he can nibble on your leaves! Mm!" Poppy snickered.

"Really? He can nibble on my pussy too!" Val said.

"But first your leaves," Rose smirked. "You gotta eat your vegetables if you wanna have dessert."

"Hey......um ladies, Val," Gust greeted them.

"Hey Gust," Val sighed.

"So, what song will you plan to sing for the musical showcase?" Gust asked her.

"Usually covers and some original songs from my third album Oni Punch," she answered.

"Oni huh? Is that a Japanese ogre?" Gust asked again.

"Yeah," she answered with a laugh.

"Say, do you wanna go to my room for the night?" he asked her.

"Sure, why not?" she smirked.

"Ooooh! This is your chance!" Rose said.

"Yeah, you can finally have your first time with Gust," Poppy added.

"You know, you should read this new book from the novel series, Platinum Crown," Rose said. "Queen Rosenwyn broke up with Chariton and was all alone until she met Sir. William Lyndon."

"Hey, I read it too, you're not the only one who loves this hot shit," Val said.

"Do you have an idea after reading the books?" Holly Darlin' asked her.

"After reading the chapter about the centaur friend having sex with his wife, I got an idea about what I should do with Gust," Val smirked.

That night, Gust and Val entered the room together, wearing only robes.

"Hey Gust," Val greeted him.

They entered his room and admired the aesthetic of the mix of antiques and modern designs.

"Cool room," she complimented him.

"Yeah, I love the combination of old and new," Gust added.

"Me too," Val said.

"I always thought....." he stammered until he turned around to see that Val removed her robe, revealing her curvy, toned body with D-cup tits, sinewy arms and legs, and a curvy butt. She was standing before him seductively.

"Come on Agustin, I know you want this and I want to make you mine," she said, as she slowly walked to him, swaying her hips.

Gust's mouth went dry as he was staring at her and he felt himself hard. His robe fell off his body, revealing his muscles and thick cock that was dripping inside three layers of condom.

"Damn, your pre cumming," she gasped.

"What do you have in mind?" Gust asked her.

"Wanna horseplay?" Val asked him.

"Sure, if you can prove yourself as a cowgirl," he smirked.

Val smiled snarkily as she pushed Gust onto his bed and she climbed on top of him. Gust started kissing her roughly and they started caressing each other's bodies.

"You're a fucking hard kisser," Gust complimented her.

"Nah, there is no way I'm letting this goddamn go but hey, I'm gonna give you a horse-sized fucking," she crooned.

They kissed again but this time, she felt him lift her leg and shove his cock into her pussy, which is fully wet.

"Wow, you're like a horny mare," he said.

"Ahh!" she moaned sexily as she felt him slide in. She gasped at the size of his weenie inside her inner walls, feeling it becoming tight in her vagina. Gust then took one of her boobs and played with her nipples as he kisses and roughly bites her neck.

"Ach, Gust!" she gasped,

He trusted up and down as she gasped and moaned at the feeling while riding him. She arched up her pelvis and thrusted her hips, which Gust is holding on her waist. Val stooped down to Gust and kiss him roughly as he ran his hands over her boobs and stomach as he thrusts faster and harder.

"Gust," she panted.

Gust smirks and growls as he goes with all he had as her body was shaking violently. Val let out a blood curdling scream and came over and Gust blew his load inside her.

"Wow, you really did make a good cowgirl," Gust complimented her.

"And you're such a good horse," she responded.

"Can I get my turn?" he asked her.

"Sure, since I'm your mare, you'd be my stallion," she responded as she got off him and lay down beside him on the bed.
