"That's it y/n. Just one more rep", said Changbin as he helped you off the bench. He recently started teaching you how to bench weights. You were always into working out. And it was at this very gym that you met him. You were at the gym around midnight that night, an unlikely hour for working out, but that's what you liked. No one to disturb you. Peace and calm after a long day as you work on yourself, that's what you craved. You were listening to your usual gym playlist when he approached you for the first time. You had seen him around, in the gym and in your apartment building. He introduced himself to you and you started off as gym buddies, helping each other with exercise routines. Then you started hanging out as friends.

But everytime you were at the gym, you couldn't take your eyes off of him. He was sculpted. His muscles bulging, sweat dripping, his bulking frame lifting weights. That was all you could think of. You could say you had a crush on him, that was growing every time you were together. It became stronger as he started training you in benching weights. His hot breath fanning your neck as he helped you position your arms properly, His fingers brushing over you, holding your fists around the weight. His sides caressing your legs as he moved from one side to another. All of these were blurring your mind. All you could think about was him.

"Okay, rest up now. Let's do your last rep after a break", he said, picking up a foam roller. You knew where this was going. He had already done his hamstrings. Now he was about to do his quads. Oh how hot he looks when he does quads. You envision yourself under him every time. You look at him as he moves his hips on the roller, thrusting into the air. If you weren't hot from the exercise before, you definitely are now. You feel your slick pooling up in your panties. You keep ogling at him with your mouth wide open. He is facing away from you so you thought he didn't catch you. But you aren't aware that he is watching all of this from the reflection of the mirror in front of you two.

You snap your head in another direction as he gets up. He puts away the foam roller and walks towards you. "On the bench, right now!", he commands. You comply, unsuspectingly of his intentions. You position your arms to hold the weights he was supposed to give you, but he holds both of your wrists with one of his and pins them above your head. " You think I didn't see you staring at me huh? You looked so desperate you know baby?", he asked, looking right into your eyes. "Uhh..Binnie, I..I w..was", you stutter. "Shhh baby!. Don't even try to deny it. I caught you looking at me many times. Do you think I'm hot? You like it when I lift weights and flex my muscles?". You just nod, not trusting your words. "Words baby, I need words. I need you to tell me what I do to you...and what you want me to do to you right now", he whispered, ending with a graze on your earlobe. "Fuck! You are so hot Binnie. I love how your muscles look when you lift weights and do push-ups. I especially love it when you do your quads. I always imagine myself under you. You make me so wet. I want you to use me. I want you to fuck me. Right here on this bench", you reply all in one breath. He let out a deep chuckle. And the next instant, his lips are on yours, capturing you into a heated kiss.

You could taste his sweat on your tongue, but you are way too past into pleasure to think about it. His lips were soft and kissable. You both chewed on each other's lips. You felt his tongue prodding at your mouth, eager to enter. You let him in. His tongue immediately started exploring your mouth. You pulled him onto you by his hair, deepening the kiss, if that was even possible. You broke this kiss to take a breath. He immediately went to attack your neck with kisses. Then he rose up and removed his tank. Your eyes blew wide open at the sight. You had seen his bare back before but this view was on another whole level. His pecs looked sturdy and smooth. His abs were starting to form on his abdomen. His biceps were shining from the gym lighting. His whole body glistened with a thin sheet of sweat. He looked heaven sent. "Changbin...", you trailed off. "Yes baby?"."You look so good. Wow....just wow!". That's all you could manage to say, before he kissed you again.

He slowly ran his arms under your tank top, pushing it up in the process. You lifted up, letting him take it off you. Then he moved to remove your shorts too. You pulled his shorts and boxers down, freeing his hard cock. It was of an average height, but the girth! "Oh my god! Binnie do you think it will fit?", you asked him. He chuckled in return."Guess we'll have to see", he said, pushing your panties to the side. He used his middle finger to draw up a line from your slit up to your clit, and back. "Oh baby, you are so wet. I think you will take me easily", he said, playing with your clit with his thumb. He held his shaft with the other hand and rubbed its angry cock head against your dripping pussy.

He slowly started to push in, inch by inch. His cock was hard to let in. It was very girthy and huge. But you somehow managed to fully sheath him. He looked deep into your eyes, full of love. "Are you ok baby? Can you handle it?", he asked, concerned. You nodded a yes and started moving against his hip. He took that as an ok and started moving at a slow, controlled pace. But that self-control flew out the window as soon as you started moaning his name while your pussy clenched around his member. But that wasn't enough for you. You wanted more. You wanted him to be rougher with you. "Binnie, faster pleaseeee!!", you half moaned, half whined. He increased his pace and started to pound into you. "Moan my name baby. Say it! Let everyone know who's making you feel this good", he groaned in between thrusts.

Changbin repositions you, pulling you onto his thighs, hooking your knees on his shoulders. He soon finds your sweet spot in this position. Now all his thrusts were angled to hit it. You could feel yourself inching towards your orgasm. "Bin..Bin..Binnie.., I'm close", you whine. "Come for me baby. Whenever you want". He pounds into you even faster. In a few thrusts, you are cumming hard on and around his cock. He pulls out after you ride out your high, and empties his load on your stomach.

He slowly pulls back and lets you rest on the bench while he goes around to find a rag to clean you up. You confess to Changbin about your crush on him. "I like you too y/n. I would like to take you out on a date and take our friendship a step further, you know", he confesses.

P.S:You both end up going on a date on the weekend.
