Harry hated the floo. Traveling by floo was right between drinking one of Severus' potion concoctions and Voldemort himself. He stepped into the resort fireplace and called out their shop. He closed his eyes as the whirling fireplaces sped around him. Finally he stopped suddenly and before he knew it he was falling out of the fireplace. He prepared for the fall but he was surprised when something warm caught him.
Severus watched as Harry tumbled out of the fireplace. Using his quick reflexes from spying days he moved in front of Harry and caught him. He looked down at the black mop of hair that was leaning against his chest. Again he was filled with feelings of warmth and caring for the person there. He wanted that young man.
Harry looked up into Severus' eyes. He saw a unfamiliar emotion shining in his eyes. He had the sudden urge to lean up and kiss the other man's lips. Harry wasn't sure if he was actually leaning up but for some reason Sev's face was closer.
Severus looked down into the emerald eyes. They seemed to sparkle. Without thinking he leaned down and captured the lips. Harry, shocked but never the less pleased, kissed back. Severus half expected Harry to pull away but quickly pushed that back and ran his tongue along the slightly chapped lips. It was perfect to him.
Harry moaned lightly which allowed Severus to explore Harry's mouth. Harry brought his hands that were on the other's body and trailed them up and along his arms. They continued their path up until they were securely attached to Severus' neck. Severus brought his arms to wrap possessively around Harry's lower back bringing them flush against each other.
They would have continued their exploration of each other's mouth if it weren't for a muffled gasp and then a small thump. The two men pulled away quickly, each with their own blush accompanying their cheeks, and looked at the door where Molly Weasley was currently laying down passed out.
