Not at all

You might have expected that all the leaping around and suchlike would make it hard for your students to concentrate on the subject in hand, but unfortunately, two pairs of shapely breasts bobbing about in tight tops, finely honed thighs rippling with activity and inviting rumps momentarily revealed by ever-so-short billowing skirts does far more to distract you than it does them and you can find no reason for complaint at their performance. In fact, the stimulating display leaves you rather hoping that you will soon find a reason to spank someone, if only to relieve your own tensions.

Combined exercise and teaching isn't common practice, and there's a reason for that. The girls soon become out of breath, which makes it harder for you to follow what they're saying, but it's not affecting the incisiveness of their comments, so you don't feel you have any reason to instigate disciplinary procedures. Nevertheless, as the tutorial draws to a close, you let the energetic pair know that it's a one off and normal service will be resumed next week. They seem quite happy with that and thank you for helping them out this week, anyway. While they pack up their things, you start to think about the upcoming tutorials.
