Theo wasn't touched by the false modesty. Oh sure he knew what he looked like, but plenty of girls would have done anything to have his attention. Some of the boys, too. Theo still would have if he had any illusions that Draco were anything but straight.
"Fishing for compliments?" he asked in a light tone. "Because I'm not the one who had a girlfriend at thirteen. Or anyone in school." Not that he had particularly wanted one. "I'm sure you'd have plenty of suitors if you only got out of this house. Not that exercise should be done to have more women, but it does make you feel better."
And he most definitely was not thinking how much better he'd feel watching Draco get all sweaty, taking his clothes off to take a shower, coming out in nothing but a towel. No, definitely not thinking about that.
"You might be faster, but I have more stamina." He leaned even closer, as if sharing a deep, dark secret. "I run up and down the stairs at the manor. Better cardio, more muscles and a tighter arse."
