We meet at the Gym

As decided, I show up at the gym. She is already there, to my surprise in a looser outfit than last time. Instead of gym tights, she wears a short hotpants that reveal her smooth tanned perfect legs, that are surprisingly long for her height. Her ass and her upper body are covered in a loose sweater though, that only gives teases of the perfect curves below it. Fair of her I thought, that might make it easier to stay professional, even though I was slightly disappointed to miss out on that sight.

I say hi and ask what these new exercises are she wants me to help her with. She says she is trying a whole new full body routine, and she wants to start with upper body. “Lets go then” I said.

Her first set on the Chest fly machine is challenging to say the least. More for me than for her. She takes deep breaths with each rep, as her arms move to the side her sweater is stretched, her boobs creating this hypnotic round shape through it. When she brings the arms to the middle her boobs are pressed together. Somehow the sweater does not manage to conceal her sexiness. Im doing good though, keeping my horny looks to a subtle minimum. I seem relatively calm and collected when giving her little tips. We even joke a little.

The Gym is empty, as its pretty late already. Just a few weirdos in the other rooms. M got a little sweat going and decides to raise the difficulty level for me with an unexpected move. “Hot in here, isnt it” she says, while wiping her sweat from her forehead, then grabs the bottom of her sweater and looks me in the eyes while taking it off, just a little bit more slowly than natural. She reveals something, that is somewhere between a sports-bra and lingerie. It must be the sexiest white little sports-bra I have ever seen, but possibly also due to the person who’s wearing it.

“My eyes are up here” she says with a smirk, visibly amused by my overwhelmed face. Damnit, I lost my cool. Nothing too bad though, I just have to focus on getting through this. The shadows from the gym light and the sweat on her skin emphasize the shape of her cleavage masterfully.

Her next exercise though, are deadlifts. This is not gonna be easy I think, while noticing the feeling of excitement in my body. Without the sweater, her perfect ass is revealed now, looking more round and spankable then ever before. She seems to make the movement wrong on purpose, and uses me adjusting her hips to push her ass into my crotch, then slowly going down, grabbing the bar, and going up while my dick is massaged between these perfect cheeks. I’m instantly hard. She feels it.

After a second, I snap out of it, go backwards and pretend like nothing happened. She turns around, smiles at me, looks down at my crotch, back up and smiles even bigger. She has a look on that face that says ‘Too easy’.

She then positions her camera next to her with the explanation, that she has to film her deadlifts to document her form and progress herself. We both know that she wants to document sth entirely different, but what can I say. I carefully try to stand outside the camera and control my looks enough to not be obvious. But with every time she goes down and up, it gets more difficult. This looks even hotter than the squats last time. I feel the bulge in my pants widening, and decide I have to get out, before she somehow catches me with that camera. I say: “Looks great, I see you got this here. I go to the bench for some sets. See you later.”

She doesn’t respond. I go to the bench and do my warm-up set, while being proud of myself that I managed to escape. M obviously didnt like that at all, and while doing my first set, she suddenly stands in front of me. I’m laying on the bench, looking up at this perfect body, then to her face, that gives me a serious look. Without saying anything, she steps forward and sits down onto my crotch. She then leans forward, coming down towards my face, just around 10 inches away. She looks down into my eyes and says: “Didnt you want to help me with my exercises?”

“Of course” I respond.

M: “Then you better stop playing around here and focus on me.”

She then leans further down. Her lips come dangerously close to mine, in the last inches she slightly moves to the side, her cheek touches mine and she whispers seductively into my ear: “I know you will like it. You dont want to miss it, do you.”

She then slowly leans back, her pussy is directly over my dick, with just some thing layers of clothes between. She gives me one slow grinding motion, that smoothly transitions into her standing up. I am rock hard at this point, and she doesnt even have to look at my bulge to know. She just looks into my eyes and waves her hand, signalizing me to follow her. I do without a word. Whatever that just was, it felt insane.

She leads me to the Pull up bar, and asks for my help, assisting her at her hips on the way up. She feels my excitement and nervousness when I slowly put my shaking hands at her hips. I know her camera is filming all of this, but I can hardly say no to assisting her here, at least thats how I rationalize it.

We beginn, as her fantastic body rises up and down in front of me, her fit tummy, her boobs, just inches away from my face. My hands on her hips, just inches away from her ass. The way I’m grabbing her hips ist just how I would grab them if I would be fucking her, thats what I’m thinking right now.

“Catch me!” she says out of a sudden, while releasing the pull-up bar, falling forward onto me. Instinctively I switch my grip on her hips to one around her legs, partly onto that perfect ass with my left hand. Her boobs glance my face in that forward motion. She is now in my arms, my slowly letting her down.

I’m overwhelmed. My arms feeling the soft skin of her thighs, my left hand on her ass, her boobs lowering in front of my face until they are pressed against my chest, her face getting closer and closer to mine as I slowly let her down. Her lips are slightly open, she looks at mine. Then into my eyes. Our lips get closer, its going to happen. I want it so bad. For a moment, only the 2 of us exist nothing matters. Our lips touch featherlightly, and sparks shoot through my body. Somehow I suddenly remember, the camera! Not only am I cheating on my GF, I do it in front of Ms camera. I need to stop, I need to get out. Somehow I manage to walk backwards, Ms arms still wrapped around my neck.

M whispers in an innocent, yet seductive tone: “You dont want to kiss me?” I just look at her, speechless. M says, still whispering but slightly more provocative: “I know you want to kiss me. You want me.”

All I can do is shake my head and whisper a barely hearable, pathetic “No”.

She says: “Our lips already touched. Its too late, you might as well get…” -she licks her lips- “..get one proper taste”

I that moment I lose all control that I have left. Our lips touch, then embrace each other. Our mouths open more and more, until our tongues start to play wildly with each other. We are escalating into the most passionate kiss, and I am overwhelmed with arousal.

Suddenly I snap out of it again. What have I done?! She looks at me with a naughty and triumphant smile, while I, to my relieve, confirm that I managed to move away enough to be out of frame of her camera. She notices my relieve, just to then shatter my world with the words: “You know what I love about gyms? Mirrors, everywhere.”

Fuck! The camera fully captures the mirror with us in frame. I’m busted!

“Its too late now, you might as well get one more kiss” she says before biting my lower lip, then pressing her body against mine and her tongue inside my mouth. I dont know what I was thinking in that moment, probably nothing. I was just in the moment, giving in to her, fully embracing that make out. I’m on camera anyway in that mirror, I fucked up.

Apparently its not enough for her though. While running her hands over my body, putting my right hand on her ass and my left hand on her breast, she pulls me slowly into frame. An unsharp reflection of my unfaithfulness in the mirror is not enough for her. She wants her proof to be perfect. I cant resist. In front of her camera, that was supposed to film her work out is now our passionate, wild make out. And I cant stop. She tastes so good, her body feels so good, I am so hard and horny. I must have a pulse of 200.

Only when a group of guys enters the room our lips disconnect.

This felt so fucking intense. But while the excitement goes down, reality kicks in, and I realize what I’ve just done. I most likely just ruined my relationship, my future with my girlfriend. For a kiss.

I instantly try to convince her to not tell or show this to my GF. I beg. She seems just amused by it. She laughs and then suggests, that if I do everything she demands for 1 week, she will delete it. Of course that doesn’t count for any new evidence that might emerge, just the one she has until now, so I gotta be a good boy in that week. A faithful one. And she says nothing of what she will ask me will be sexual. Just errands, driving her to places etc are part of the deal. Just being her personal assistant, free of charge.

Sounds like a no-brainer. Sounds like my only chance to save this.
