Set in an alternate universe : Ruben is a personal trainer and he helps train reader because of her issues.

Enjoy!

"One more, you can do it!"

"I can't do it Ruben."

"Yes you can. Come on Y/N, one more step."

"No, Ruben. You're pushing me too hard."

"Y/N, it's just one step. You can do it."

He was right about that. You put everything into taking that one step. Your last step before your legs buckled beneath you. Fortunately, Ruben was the to catch you. He was always there to catch you when you fell.

"Fuck." You winced as your hands touched the floor. Ruben caught you just in time with his arm around your stomach. However, he did not prevent you from scrubbing your knees.

"Are you okay?" Ruben picked you up and carried you over to the nearest bench. You hated when he did that. It reminded you of the times you fell as a child. How your parents would get so anxious to let you outiside and play with your friends, fearing that you would hurt yourself again. However, doctors told you that having fragile bones will come with its challenges in life, and up until today, you have always been able to handle those challenges by yourself.

"I should put a band-aid on that knee. Other than that, everything looks fine."

"Don't bother." You told Ruben, who had gotten up to retrive the gyms' first aid kit.

"Y/N, but you're bleeding?"

"It doesn't matter. I want to go again." You made the effort to stand up. However, your legs quickly retaliated, wobbling beaneath you, making it impossible for you to walk unless supporting yourself. Luckily, you found Ruben's bicep, clinging onto it for dear life.

"That's it, I'm driving you home." Ruben said and did not give you time to protest. You drove home in silence, with Ruben stopping the car right outside of your apartment complex.

"I'm sorry if I pushed you too hard today." He said, shutting off the car engine.

"Isn't that your job?" You chuckled.

"It's what you pay me for, yes. But I tend to forget that you're...."

"Weak." You nodded and looked to your hands.

"Not weak." Ruben sighed. "I was gonna say fragile."

"It's the same thing, Ruben, and you know it."

"It's not."

"Whatever." You cracked open his car door, making the attempt to step out of Ruben's car. However, you quickly realized the effects of today's workout. How it left you more fragile than normal, completely unable to walk.

"I got you." Ruben appeared before you faster than you could comprehend. He did not hesitate to bend down and pick you up in his arms, carrying you inside your apartment building.

"Somedays are worse..." You said. Ruben unlocked your apartment door and carried you to the living room, setting you down on the couch. "But the fatigue will ware off eventually."

Ruben did not look as convinced. It was clear that he refused to leave you alone until he was sure that you were okay. This has only happened once before after one of your sessions and even back then, before the two of you had gotten to know each other, Ruben promised to stay with you as long as you needed him to.

"Here, drink some water." He said, passing you a bottle from your fridge.

"You don't have to do this." You sighed and fell back on the couch after taking a few sips of water. You found the remote and turned on the TV.

"I don't think it's a good idea to wait it out." Ruben said regarding you skeptically as you relaxed on the couch.

"It usually just takes a few minutes." You assured. "I'll be back on my feet in no time."

Ruben still didn't look convinced. "We have to increase the blod circulation in your legs." He said.

"We?"

"Yes, we. I'll help you stretch."

"Oh, boy. Here we go again."

Ruben had already joined you on the couch, massaging the bottom of your feet. All though it felt amazing, all you wished was for Ruben to leave you alone. You were already embarrassed enough, self-conscious about the fact that your clothes still smelled of sweat. Ruben, on the other hand, smelled amazing. Like liquid soap and a dash of aftershave.

"Please, Ruben, this is really not necessary. I don't want to be a burden."

"You're not a burden."

"I know, I just—"

"Y/N." Ruben stiffened, regarding you sternly. "You're not a burden to me, okay? Not to anyone, for that matter."

You heart fluttered. "Ruben I..."

"It doesn't matter." He said. "Just let me take care of you."

"Okay."

You fell back on your couch and let Ruben take care of you. He was obviously everything you wanted in a man. Kind, strong, and handsome. The undisputed three. However, you were quite convinced that a guy like him could never be interested in his opposite, a girl like you.

"Is this okay?" Ruben moved on to message the lower part of your back as you turned over to lay on your stomach. "Y/N, you have to tell me if what I'm doing is okay or not."

"It's okay." You sniffled, having failed to answer him the first time. Ruben stopped what he was doing, a gentle hand on your back. "Y/N?"

"Please, Ruben. I'm fine, really."

"You don't sound fine."

He was right, and you weren't. Your emotions bubbled up, causing unwanted tears to flood your eyes. You tried to hide them by nuzzling your face against the cuchens. Unfortunately, Ruben felt your body shiver. His expression softened as he made you look at him. It was the first time he saw you crying.

"Ruben, I..." You tried to excuse your tears, but Ruben wouldn't let you. His hand on your cheek forced you to look at him as his thumb swiped away your tears. "No one is weak for showing emotions." He said, with a voice so rich and so deep that a part of you wondered if he was getting emotional as well. "You're not weak, Y/N. You're just human."

"A very fragile human." You chuckled. "I'm starting to believe the kids that used to tell me that I was made of glass."

"Well, believe me." Ruben tilted your head, his gaze soft and kind. "You're not made out of glass. The complete opposite. You're made out of resilience and whatever made the stubborn and beautiful woman that you are."

Again, your heart almost escaped your chest, blood rushing in every direction of your body.

"What?" Ruben said, seeing your expression.

"You....you think I'm beautiful?"

Ruben's eyes widened when he realized. "Oh, I....well I....." His cheeks blossmed. "Y/N, I....."

"Yes?"

"I didn't mean to...."

"To?"

He shook his head, snapping out of it. "I'm sorry if I've made you uncomfortable."

"Uncomfortable, why?"

"Well, I'm not exactly in a good position to...." His hand left your face. So did his other hand on your thigh. "I'm your trainer. It would be highly inappropriate for us to..."

"To?"

"To...you know."

"I do?" You frowned.

He sighed. "Y/N, it would be highly inappropriate for us to engage in anything....sexual."

"But what if I want to?"

"You do?"

You shrugged. "Only if you want to."

He looked tempted. Considering it. However, with furrowed brows, he shook his head. "No. We can't. We can't because of your legs."

"My legs?" You looked down on them and realized that you were able to wag your toes again.

"Their tired Y/N. You're tired from today's workout."

"Right, tired." You brought your knees up to your chin, wrapping your arms around your legs. "Or perhaps you mean fragile?"

Ruben's stiffened. His entire demeanor uncertain. "Y/N, I never meant to hurt...."

"My feelings? Yeah, guys have told me that all my life. Don't worry, I've learned to protect myself from guys like you."

He frowned. "Guys like me?"

"Yes, people who pity others for their disabilities rather than recognizing their abilities and what they can do. Who they truly can become."

"Y/N, there's no doubt in my mind of your abilities. You're stronger than you realize, and It's my job to help you realize that. However, it is not my job to fall in love with my clients, and I'm afraid that I've done just that."

"What?"

Ruben nodded, his hand on your thigh. "Your beautiful Y/N, flaws and all. But you're also stubborn, too stubborn."

"What can I say...." You smiled. "I know what I want." You pulled his shirt, tugging Ruben towards you. He resisted at first but eventually went down willingly, your lips colliding in a gentle kiss. The kiss lasted as long as you allowed it, with Ruben pushing you down to lay beaneath him on the couch. There, his hand wrapped around your throat, squeezing it gently, teasingly. The sounds of your smacking lips filled the living room, dimming the sounds of the TV.

Although Ruben convinced you to be the one to keep it in his pants, it did not take long for his erection to poke you in the stomach, reaveling the size of him.

"I want you." You moaned.

Ruben gritted his teeth, stroking his hips against your thigh. "I want you too, baby. Trust me. But you should really take it easy."

"Fine." You pushed Ruben off of you and came to a rest on your knees. "I should take it easy, but not you." With a hand on his chest, you pushed Ruben down to sit back on the couch. He did so with his legs spread, his erection a visible bulge through his pants.

You slid down onto the floor, getting to work right away, pulling down his shorts, setting his dick free. Ruben groaned as you grabbed onto his large shaft, squeezing it gently in your hand.

"Do you want me to suck it?" You asked, your lips already pressed against its tip.

"Suck it, blow it...do whatever you want, baby." He was eager, so eager that it made you giggle. Nevertheless, placing one hand on his thigh for support, you took him into your mouth, letting the size of him tighten your jaw.

"Fuck....yes." He sighed. Even more so as your head started moving up and down, sucking him clean.

"Yes baby, just like that."

You showed no signs of slowing down. However, with a hand gripping the back of your hair, Ruben slowed the motion, derminating the speed to one he liked. "Just like that baby, nice and slow."

Sometimes, he made you go faster. Praising the way you gagged on it before going slow again, allowing you to recover.

"You're such a good girl baby, such a good girl for me."

His dick was soaked in your saliva, the warmth of his skin caressing the insides of your cheeks. Slowly but surely, you edge him closer to his limits. To a point of breaking.

"Fuck baby, I'm gonna cum. I'm gonna cum so hard for you, please don't stop."

You didn't stop. Instead, you upped the pace, adding on to the friction by using your hands. Ruben's head fell back with pleasure, squinting his eyes as he moaned your name.

"Fuuuuck!"

Ruben sighed with the relief. You backed off and wiped the corners of your mouth as he looked to you in disbelief, slightly impressed. "You're crazy, Y/N. The craziest girl I've ever met."

"Thank you." You smiled.

He pulled you up to sit in his lap, kissing your mouth without hesitantion. "No baby, thank you."
