Thor...

You decide to partner up with the giant blonde who you’ve labeled Thor. Ariel partners up with the black guy with the goatee. You introduce yourself, and you learnt that Thor’s name is actually Brent. Of course, you immediately start referring to him as Thor out loud, and for some reason he doesn’t seem to mind.

The first exercise you’re doing is sort of a Simon Says type of thing where the instructor call out a series of punches with the partners take turns getting punched in the hands. You start out as the puncher, which is fun. You make sure to really bounce around the whole time and really put as much strength as you can in your punches. Thor is clearly enjoying all of the bouncing around, and you can’t help but notice his gym shorts tightening a little bit.

The exercises go pretty smoothly until you get to the heavy bag. With the heavy bag you’re supposed to take turns using your weight to hold the bag while the other person punches. By this point you were already exhausted, so when it came time to support the bag, Thor’s thunderous punches easily overwhelmed you. You tried just holding it with your arms, but couldn’t, so you hugged the bag and used your weight to back it up. This worked for a while, but before long you were getting a little punch drunk. Then, with one particularly firm punch, you fell back and hit the ground, knocking the wind out of you.

When you came to Thor was standing over you with obvious concern on his face, but also a slight smile. It took you a second to realize why. As a result of being pressed up against the bag, your bra had slipped up over your breasts. You little conical brown nipples were just peeking out under the elastic of your bra. You let Thor help you up, trying to maintain a little dignity. It took a few moments of uncomfortable fumbling, because of the gloves, but you managed to cover up eventually.

“Don’t worry, I don’t think anyone else noticed anything, and I won’t say anything.” Thor was trying to be gentlemanly, but he couldn’t disguise the fact that his gym shorts had taken on very strange dimensions.

“That’s all right, we’re at the gym, we’re all adults here, right?” As you said this you lifted your boxing glove so that it just slightly jostled his package.

The rest of the class passed uneventfully. When the class was over, everyone was exhausted sweaty. You walked to Ariel, who had partnered up with the black guy who’s name is Devon. Thor and Douchebag joined the three of you.
