Too shocked to react in time

Harry stared at his, well her, friends covered dick in shock. Ron had never been a shy guy, he'd always been the one to walk out the showers with no towel or sleep in the nude and forget to put on some clothes before he opened his curtains, so the sight of his covered dick shouldn't have been such a shock. But seeing it soft didn't prepare her for the sight of it hard and straining against the confines of his boxers.

Even soft, Ron was able to make Harry feel insecure, his package was easily 6 inches long flaccid and he wasn't shy about showing it off. His balls as well, they always looked so plump and full and put Harry's to shame. But Harry had always assumed Ron was a shower and not a grower, mainly in an attempt to make himself feel better, but clearly he, she, had been dead wrong.

Even covered by the meager protection of his boxers, Ron's package was obviously a lot bigger than 6 inches. She couldn't tell for sure but judging by how it looked ready to rip through them, he'd grown a few inches easily.

Ron grew impatient with 'Lavenders' dawdling, but seeing her wide eyes and the way she bit her lip as she glanced between his face and his cock, he knew what she was after and it made him even more excited "Oh, so it's gonna be like THAT huh?" He said with a smirk. Lavender and he sometimes played a little, having him take control and man handle her occasionally. They never took it too far and they had an easily remembered safe word, Snitch, but she liked to give a little resistance and have him 'over power' her.

"Just remember the safe word" He said, not giving the confused Harry time to ponder his words before Ron was tugging her forwards and rubbing his bulge against her pretty little face "Now, get my big, fat cock out and put that pretty mouth to work" He ordered, his dick throbbing with pleasure "Or else I'll just have to move straight to the main course" He said with a leer, pulling her head back.
