A few days ago some friends invited me to the gym. I usually stick to home workouts but decided to join for the company.

The two of them (24f and 23f) were doing chest while I was working legs. They were sitting at a bench nearby discussing form when the older one, who I have been crushing on for some time now and also happens to have the most gym experience in the group, laid under the bar to show our other friend how there should be a bit of an arch in your back while chest pressing. She then jokingly gave some more examples, first flattening her back completely before arching it a whole foot or two off the pad of the bench.

For context she's a bit of a gym rat who works out nearly every day and her toned, lean body really shows it. I often see her in gym shorts or leggings but this was the first time seeing her in a complete gym outfit and every item of clothing was skin tight, leaving nothing to the imagination. As she exaggerated the improper technique to us, we couldn't help but stare for a moment at our friend's crotch raised in the air.

Her leggings weren't black thankfully, making it much easier to see the outline of her panties underneath. The seams ran from her prominent hip bones all the way down to form a small triangle that perfectly enclosed an even more perfect mound. Just beneath that was the unmistakable outline of her lips. By no means was she rocking a camel toe but the fabric was stretched in such a way to show that she definitely had a nice juicy pair between her thighs that anyone would be lucky to bury their face in. All of a sudden those fetishes of being crushed between a pair of muscle mommy thighs began to make sense because that's all I wanted in that moment.

She lowered her back just as quick as she had raised it, but that image of her delicate curves on display for us, and the rest of the gym, has been on my mind ever since.
