The oooh this time was unvoiced but Charlie knew very well that he had been noticed and that the other man, and why hadn't Charlie noticed him before he wanted to know, was glancing from time to time.
Possibly to find out if Charlie would rupture himself if he did this - shoulder stand with full split.
Nope, though he had to admit that one hip had twinged a bit. Charlie brought his legs together then lowered his toes to touch the ground. A gentle controlled slide until he was laying flat on his front, two deep relaxing breaths, then he pushed himself up to go and play on the vaulting horse.
That would give him and excellent view of the man at the bag, and not in the mirror either. He'd be able to get the whole sweatily gorgeous effect. Not that he would ogle - that was very bad form and tended to upset straight guys, the dears - Charlie was far too polite for that.
