There were no missions today. Father and mother were busy with clan meetings, leaving Itachi to spend the afternoon with Shisui. They had wandered off towards the ravine as they usually did, bringing sweets with them. They watched the birds fly overhead, neither bothering to fill the peaceful silence with useless prattle.
It was while they were eating that Shisui quietly slid the small white box towards Itachi. The Uchiha set down his food and looked at the box in interest. He met Shisui's eyes and the elder nodded.
"Open it." He prompted. Itachi curiously did as he was told, lifting the lid off the box and setting it down. When he saw what was in the box, the younger Uchiha looked up in surprise.
"Shisui-" He breathed, gently lifting a necklace from the box. "Thank you." Shisui smiled fondly at Itachi, murmuring a you're welcome as he watched Itachi look over the jewelry.
The necklace had three small metal loops equally spaced on the black material. They shined in the sunlight, catching the rays just right. Itachi could not fight down the smile that was spreading across his face. He quickly looked down at his bare toes, feeling Shisui's eyes on him.
"You really didn't have to-"
"Itachi," Shisui began, voice dripping with amusement. "I wanted to. Now come here so I can put in on you." He motioned to the younger boy who obediently walked forward. Shisui stepped behind Itachi and brushed his hair away from the back of his neck with a gentle hand, pushing Itachi's ponytail over his shoulder as he clasped the necklace around Itachi's neck and breathed softly against the flesh. Itachi's breath hitched ever so slightly at the feeling of Shisui's breath against his neck. He gripped at the strands of his long dark hair as he turned his head towards Shisui, thanking him with a smile. Shisui's fingers gently brushed Itachi's hair back into place, petting the dark strands with loving fingers.
"Happy birthday, cousin." Shisui murmured against the back of Itachi's neck. He felt Itachi lean against him and the older boy grinned. His hand moved to glide over Itachi's cheek and the boy turned to face him, lips curved into a genuine smile that made his eyes sparkle.
"Thank you, Shisui." He replied and before the older boy could respond, Itachi moved to stand on the tips of his toes so he could brush his lips against Shisui's in a chaste kiss that left both of them breathless.
