Harry Potter and the Connubialis Hex/The Burrow/Ron and Hermione/Harry has afterthoughts
From Create Your Own Story
Ron put a kiss on Hermione's cheek and rolled on her side, his legs still outside the bed. Hermione crawled on the bed to rest her legs on it.
Seeing Ron and Hermione like that made him smile. But it faded quickly. All of a sudden, everything came back at him. He was waking up from a dream, one that was too good to be true, that guilt stabs you like a knife in your stomach. Harry freaked out.
Hermione looked at Harry. She saw the change in his face. It frightened her. "Harry? What's wrong?"
Harry was looking at an invisible point on the wall and couldn't take his eyes off it. "What's wrong? Everything's wrong." He turned his head to look at Hermione. "What we did was wrong. What "I" did was wrong."
"Harry, it's not wrong. It just happened. We all wanted it, nobody imposed it to the other."
"Yes I did. You asked me out of the room and then I casted that spell."
Hermione was now sitting on the bed. "What spell?"
"Conni..." He was about to say "Connilingus" but he knew that wasn't it. "Damn, I can't even remember it!" Harry was so confused.
It was Ron's turn to sit and did so on the end of the bed. "What are you talking about? You didn't cast any spell, Harry." he said, like he was questioning Harry's sanity. "Yeah! We freaked out when you got got in my bedroom but we were into it and wanted tou to be part of it."
He looked at Hermione and had the same look as Ron. They didn't remember that he drew his wand and forced them to obey to his lust? Did he just imagined that? They couldn't lie to him, not on something like that. Or was the spell he casted (though he wasn't sure anymore he really did it) powerful enough so the person didn't know it happened?
"And don't worry, nobody will know about it, Harry. It will be our secret." Hermione said. He was now staring back at that invisible point on the wall. Ginny... He couldn't imagine how much he would hurt her if she knew he cheated her. It would hurt her too much. And with her Ron and Hermione? She would be devastated.
Harry was lost for words. He remained silent for a moment, everything spinning in his head. He suddenly fell very tired.
"I think it's better if I go now."
Hermione tried to comfort Harry: "Don't be too hard on yourself."
Harry dressed and got out of the house. He walked a few meters outside and apparated back at Grimmauld Place.
