Vianna allowed the corners of her lips to curve into a mischievous smile, though she tried to hold it back and not show any amusement as she continued kissing Ferris, quite pleased with his response. She allowed her hand to find its way back to his curly hair and let their lips continue kissing for a couple more moments before abruptly pulling back. "Do you want any more marshmallows before you have to go, Professor?" she asked him casually, as if they hadn't just been kissing a second ago. "I could make some more before my brother gets here, maybe you'll get hungry as you wait for them to fall asleep."
