As the boys ambled off in the general direction of the dormitories, Hermione felt hot breath on her neck as the smell of cider wafted over her and a melodic voice whispered,
"After party in the room of requirement. Care to join?" A single red wisp tickled Hermione's bare shoulder, as though she needed more temptation.
They paced past the door together, arms linked, imagining the debauchery within. The door appeared quickly, and they were greeted with a large, dimly lit room and fast music. Couches formed small seating areas in alcoves tucked along the walls, and Ginny let her arm slide through Hermione's, taking the other girl's hand and leading her to the nearest empty couch.
"Champagne?" she asked, offering a sparkling bottle.
"Where the bloody hell did you-"
"Between the couch cushions!" squealed the delighted Weasley.
"Are there glasses?"
"In the couch?" Ginny shot Hermione a concerned, penetrating glance, as though checking for other signs of madness.
The bubbles rolled delightfully over their tongues as they passed the bottle back and forth. After swallowing the last swig, Hermione stood up.
"I wanna dance!" A serious look came over her face as she stood and extended her hand to the younger girl. "Ginny, will you dance with me?"
"Yes!" was the squealed reply.
They stood closer and closer as the night wore on. In time the party wound down and they crept through the halls toward Gryffindor tower, clutching each other for support.
"Ginny!" Hermione gasped, as they walked past one of the castle's infinite windows and were illuminated by the first wisps of dawn, "you look like a princess!"
"A drunk princess!" Ginny giggled, delighted with her description, and leaned closer to the warmth of Hermione's bare arm.
"Shh!" Hermione hissed loudly, and both girls ran the rest of the way to the portrait.
The common room was deserted. Standing at the foot of the stairs leading to their dorms, they paused and exchanged an intense glance.
"Waiting for a kiss goodnight?" Hermione quipped quietly.
"Well I am a princess, after all."
"If the princess insists." Hermione leaned in, letting her lips brush Ginny's. It felt nice, and oddly right. As she pulled away, Ginny followed her, planting a slightly firmer kiss. Stunned, Hermione didn't pull away. The other girls lips moved slightly against hers, and before she could stop it, her tongue darted out and grazed Ginny's lip. The smaller girl shuddered but didn't pull away. Shocked at her own boldness, Hermione rushed up the stairs, peeled off her dress, and fumbled through the heavy curtains into her bed.
