Indeed

Harry watched his friends pull off their t shirts and undo their bras. His only conflict was over where to look.

Ginny’s body was not new to him, of course. They’d grabbed at each other while they were dating, but it had been relentlessly frustrating. In public, they’d get interrupted after a kiss lasted more than a few seconds. Much the same happened in private. For one example, Harry had been grinding against her in a dark hallway. She was grinding back. Breath uneven, gowns fluttering between them. And a large group of classmates came by, whisking them away.

Or the time they’d walked to this very lake, late at night, covered by his Invisibility Cloak. Sitting alone in the dark, kissing, Ginny had, for the first time, found his cock with her hand, had pulled it free, and had pumped him a time or two when Hagrid appeared and nearly tripped over them. He escorted them back to Hogwarts.

Or the time on the Hogwarts Express, after they’d closed the blinds in their cabin. Harry had been feeling her up, squeezing and fondling. Ginny lay back, eyes closed, and Harry pulled up her shirt. Just as he’d reached down to suck on her pink erect nipples, they heard the door knob shake and rattle. Ginny had jumped up and pulled down her shirt just as her brothers piled into the car. Harry had wondered if they’d noticed her nipples poking through her shirt, or his own erection, but he’d also wondered if the twins were keeping them apart.

Or the time he was at the Weasleys for a weekend. They’d had an hour alone, and had engaged in a sweaty back and forth. Fully clothed, she’d been on top with her pants unbuttoned. This afforded enough space so that he could slide a hand onto her buttocks. She was pressing against him, and he against her, as he’d slid his hand further. He felt dampness, wetness, and then his fingers slid along her smooth slit. He felt her freeze, debate, and then slide her pussy onto his fingers. His fingers had begun a circular movement as he pulled her strongly toward her. Her breath had deepened as she made a fucking movement with her pelvis. At that moment, Mrs. Weasley had bustled into the room with some fresh laundry. The two immediately jumped part, but Ginny’s mother had to notice that Harry’s hand had gotten stuck deep inside her daughter’s pants, and when it did emerge was wet, sticky, and smelled of woman.

Or the time they’d been the last ones in the Gryffindor lounge, late at night. They were both in pajamas, sitting across from each other in well worn chairs. Harry had alternated between looking at the roaring fire and looking at Ginny, who was naked under her thin pj’s. When she stretched or moved, he could make out the sway of breast or the subtle outline of fiery pubic hair. Ginny had dropped a quill nib and had gotten on her hands and knees to find it. Harry watched her look around, crawl to him, and look up from her position from the floor. At that moment, his own cock had made a lurch, freeing itself from his pj’s. His horror melted as Ginny had calmly leaned forward, firmly gripped the shaft with her right fist, and leaned down to suck him in, and suck she did. Her mouth was wet and warm, and it had been the best feeling of his life. After perhaps 10 seconds, Harry looked up at the doorway, where Ron stood silently, mouth agape. Ron couldn’t like seeing his little sister blowing him. Not only was she his sister, but Harry and Ron had had their own arrangement regarding blow jobs on campus. Ron made a noise, and Ginny pulled back, saw him, and ran off.

But all of that was long ago, and now he was a girl.
