A/N: This if for the Romantic Gestures Challenge. Hopefully it's okay. Having never written this pairing before.
Neville glanced around the green and silver dorm room nervously. Even with all the other Slytherins gone for the Yule holiday he couldn't help but have fear that the two of them would be caught. Even if it was a silly fear. No other Slytherins were going to venture into the room of the houses leader and he wouldn't be missed in his own dorm. He never really was. Bright blond hair flashed through his sight, bringing him out of his thoughts. His plain brown orbs rose to catch the mercury colored ones of his lover, taking in the sight of Draco Malfoy standing in front of him shirtless. A pleased smirk twisted his lips upwards. One hand holding a small black pot and the other clutching a small paint brush between his fingers. Nevilles breath hitched and a blush spread across his cheeks, trying to squirm away from the intense gaze of his boyfriend. Trying being the operative word as Slytherin colored ties didn't have much leeway.
"D-Draco? I don't think..."
"Shh."
Protests cut off, if only for a moment, Draco dipped the paint brush into the pot and swirled it around before lifting it out. A dark sticky looking substance slid slowly from the brush back into the pot. A mouth opened to once again voice it's protests. Protests that were cut off as the substance covered brush made a small path from his neck, over his bare chest and down to the waist band of his pants. Neville gulped lightly as the pot and brush were set down and Draco leaned over him, arms on either side of his body. The blond boy leaned down and quickly licked the stripe of chocolate body paint off his bulkier lover.
After the chocolate had been cleaned thoroughly from the brunettes body silver eyes laced with lust glanced up into the brown eyes with mirrored his emotions. The Gryffindors full lips were parted, this time not in protest but in pleasure. Knowing there would be no more complaints tonight the blond painted his lovers body with liberous amounts of chocolate languorously. Small nonsensical squiggles became words. Words of love that were quickly swiped away by an eager tongue. After Draco, Neville moved to have some fun, having been released from his bonds. He gave the Malfoy's body the same treatment his had received. By the time the small pot was empty the two were past words. The only sounds heard by the empty dorm being signs and moans. Words of comfort and love. A adoration evident in their touches and looks that would, unfortunately, never be witnessed by the outside world.
