Tengen Uzui x Reader|| To the Gym

【Lemon】
⚠️You have been Warned!!
Early morning or into dead night. You and your boyfriend Tengen were doing reps, working on both your legs, and arms. Tengen has been working out before you got into it and is loving the results you're giving. He didn't love you differently before you making the choice though makes him proud of you. Doing something for yourself was nice.

Most of the time when you are doing your squats or lunges. You are getting great states. For the past month, Tengen had to come workout beside you when working on his arms. He glared at them with the mirror before you all. It bothered you only because you for one didn't notice and he was doing heavy PDA. When you finished, he'd aggressively grip your rear and you'd be flustered.

"Nice, Babe~... " he complimented as he massaged. You turned back finally to notice the eyes swiftly look away last minute.

"Dammit, Babe... you could just.. s-say something." You pushed his hand off and grabbed a kettlebell weight. Working on your squat and swing now.

"I'd say sorry but....! They should know better. We been here longer." He put down his weights and flicked his hair. "I'm gonna be in the bathroom." He kissed your cheek and then drank some water before going off. A towel thrown over his shoulder. The moment he left, you were crowded. You saw them approach by looking at the mirror. You turned your music off and turned to face them. More tall as hell men you had to deal with..

"Love, you're going to kill your posture. Allow me." One said but was shoved.

"You're fine. Just a little tinkering." Another said. The next person just approached you, putting his hands around your sides. Your eyes following his movements.

'I could jaw check each of them.... But Tengen did ride my nerves.' You smirked as your head was down. 'I'm no fool, I get what they're doing.' You were aware your posture was fine as you did anything, they just wanted an excuse to come over. Smart. Even if they were to mention it to Tengen, he'd still end up scaring them off. You enjoyed the attention too, they commented on your progress but they only knew you like this. There was no way you'd even think about finding another man.

"Ehem." A voice peaked, making all of you turn and luckily you finished and put the kettlebell down. Looking up at an angry tall boyfriend.

"Oh~ My Love! You weren't going to tell me my posture was bad? I could've ruined my back!" You laughed as the others looked intimidated. He looked really serious and the sweat from workout subsided since he washed up a little in the restroom. A 'tch' left his lips. The boys scattered after another thing left his mouth. He came closer to you, towering over your smaller form greatly.

"You know damn well I straightened you out." He growled which you loved. His display of dominance was strong. He patted the sweat against your back and chuckled, knowing you hate when he acknowledged it. "Let's get your sweaty ass home." He said and walked ahead with his bag and bottled water. You followed with your things close behind. He drove the way home.

"Gosh, I'm gonna be sore tomorrow. I still don't feel yesterdays..." you mentioned.

"You will." A short car ride home and he walked behind you on the steps on purpose. Your leggings were loving your figure and he couldn't help but give you love taps up the stairs.

"Damn, c'mon now." You complained as he continued while you unlocked the door. When going inside you wanted to rush to the shower, you knew what was to happen. Tengen reached for you and pulled you in. Your bodies together after another workout. He gave you a messy kiss while holding your body in his arms. Groping you lovingly, you pushed away. "Babe! I-I don't like this, y'know?? Can I.. please..." you begged, flushed in the face. His hand glided between your legs and rubbed against the hot spot. You whimpered before he suddenly brought you to the couch. Bending you over the arm of one of the chairs and peeling your leggings down. He lifted up your top, it was a long sleeve crop that peeled off as well. The sweat build up fall down after being exposed to the air.

"I'm only getting you back, My Love~.." he had come behind your hips after whispering that in your ear, his tongue then pressed against your entrance. You moaned in response. He added a digit and smooched against your clit. You were shaky from his pleasure,listening as his sweats next hit the floor faintly. He then stood up and placed his length against your back. It made you nervous. "Maybe... you'll learn from this?" He chuckled looking down at you, the grin he had on his face was aggravating but so alluring. You lowered your head in acceptance. "There we go~.." he grabbed your cheeks a little hard, you whined and felt him push his length in fast.

"Yah!" You yelped, your walls twitched frantically, he let out a growl and then chuckled again.

"Don't worry~... You'll get your shower riiiiight after this..." he started moving fast immediately. Your hands gripped the couch as he bucked his hips into you, stretching you out enough so your whimpers turned into moans. He moaned with you as he kept pressuring his hips into yours. The sweat on your bodies making the sound echo throughout the living room. He was so rough it made your mouth not close, always moaning with each thrust he gave you. You were already close and just let it out. A long moan indicating your orgasm but he didn't stop. He lifted you to where your hips were starting to peak over the arm of the couch. Your body beginning to be pressed more into the couch cushions. He towered over you, his hands now above your head and back arched. From adjusting you had enough time to come back to your senses. He was making you dizzy.

Almost after every workout, he'd either screw you before or after a shower. You could barely keep up with his needs but he did most of the work. Eventually, you adjusted to it and as long as he had the stamina, you could sit back and enjoy it. Sometimes when you'd even attempt to be dominant, he'd make sure to change that. Riding him had led to him viscously uppercutting your cervix.

After though, you were moaning again from this deeper position. The overstimulation had you drooling on the couch. He panted while above your head, and your hands grabbed onto his wrists as he pushed into you. He kept his thrusts at the same pace.

"Your gonna be.. so damn red..." he laughed from above as he then thrusted wildly. Your legs shaking from underneath him, he loved how flustered you got. Your eyes looking dull. It was extreme bliss. Ravishing. He paused for a moment, a long groan. "Aw, shit..." he growled. His length twitching. "Oh well~.." your eyes looked up at him as a sweaty mess. He grinned wide.

"Just...do it.." He loved the sound. Just getting permission even though most of the time you don't even bother. Embarrassing. He just wanted to hear how tired you were.

"Grand!" He snapped his hips back into you which made you jolt, he snaked his arms under your stomach then hoisted you up into his arms. Your back against his chest, opened legs, his length ready to back in. You noticed, the window open, looking into the patio where another room would be.

"N-No~... Babe!" You blushed and soon felt him begin his merciless thrusting.

"Relax!" He reassured continuing the motion to keep you speechless. "You're just loving it~.." he had bit the top of your ear, while holding your legs open. Your arms reached behind his head and held him firmly. Embarrassed and scared of the neighbors just step out and take in the morning. You cried out as your overstimulation was pushing into another orgasm. The walls tightening again.

"Cumin~!!" You bit your lip not being able to finish your sentence. It was then he slammed himself in one motion which sent you. His arms let go of your legs and hugged you. A long groan which broke into a pant in your ear. He came so much it didn't stay in long. He thrusted a couple more times before pulling out.

"Damn..."

"Yeah, damn..." you angrily said. "Another fit I gotta throw in the washer..."
