It bobbed up as soon as it was free, Draco’s jockey shorts around his knees and he wriggled them further down his legs and toed them off and his cock bobbed every time he moved. Hermione’s eyes fixed on it. She had seen them before – penises, she thought, and her cheeks were flaming – in photos in her research books, but not erect. It was flushed slightly darker than the rest of him, and it looked big to her but she compared it in her mind to the statistics she knew and decided it was probably not much bigger than average. But if this was what slightly-bigger-than-average looked like in real life, Hermione was happy. And slightly worried about sex, thinking about how on earth it was supposed to fit. If a baby can come out of there, then that will fit, she told herself matter-of-factly and unromantically, but wasn’t entirely reassured. It looked so...thick. And his balls were right there, nestled beneath it, soft and squishy, the skin crinkled, looking somehow alien but not unappealing. Just...funny.
