Go compete with the hottie now that you're all "warmed up"

You step over to the machine next to the hottie with the well-oogled body and ask if anyone minds if you use it. The guys give a welcome assent as your competition holds a steady stink eye at you.

You settle in, spreading your thighs against the machine's bars to lift the weights. After barely two strokes you sigh dejectedly. "These tight shorts just don't make this easy!" Your gripe draws the eyes of the boys and the ire of the girl. "Anyone mind if I just take them off?"

"Sounds good to me." A few agreeable nods and you're slipping them off onto the floor, laying your mostly bare cheeks onto the machine and spreading your thighs against the bars to expose your thin, white cotton panties, already damp enough to show off the smooth, moist lips within them.

"I always find those machines are a real pain if I've got a shirt on, too." A shirtless, brawny fellow offers.

"You think?" You cock your head and look up at him, "I see you don't hafta put up with a sports bra, either..." You tap a fingertip to your lips.

"I couldn't imagine how restrictive those are." A lean, runner type nods.

Without another word, you cross your arms in front of you, gripping both pieces of "overly restrictive" cloth and pulling them up. Your ample breasts spring free, their large, dark nipples already perky, even with the heat. Pulling your tops around your hair, you deposit them on the floor alongside your shorts.

Pressing your legs out and drawing them gently back in (so as not to knock the weights, of course!) the men draw around you, and away from the other hottie.

"The only problem now is that my breasts just get so darn hot and sweaty when I really get going..." You draw your hands under and round them, lifting them up as your thighs pump in and out. You pull your hands out, letting your supple flesh fall free, your sensitive nipples grazing across your fingers.

With a jolt, you let the weights fall an inch or two with a loud bang, letting out a giggle. "Gosh, they're so sensitive!" You sigh deeply, smiling up shyly at the men surrounding you.
