Kaitou alighted with his little package on a building about five miles away from the original heist site. Gently placing the detective on the ground he crouched behind the boy and slowly began unbuttoning the little suit jacket.
"K-Kid!" Conan squeaked as white gloved hands moved to his dress shirt, "Wha-wha-what are you doing?"
Kaitou didn't answer and instead licked the base of the little boy's neck causing him to yelp and pull away. Kaitou quickly put his hands on the child detective's now bare chest and pulled him backwards until he was flush with the thief. Using his fingers and teeth he began undressing his captive while at the same time nibbling at the now exposed skin. Conan gasped at the touch and an embarrassed blush spread over his cheeks as the long gloved fingers began unzipping his pants.
"Wait Kid, I'm still in this form ngggg." Pleasure shot through Conan's tiny body as a soft, abrasive glove rubbed against his penis.
Kaitou continued to ignore the detective's protests and instead slipped the garments from the boy's shoulders and unclipped his bowtie. Conan began to squirm in his grasp, his gasps coming in quicker and shallower as his molecules danced with excitement at a sensation he hadn't felt in nearly two years. Being in a little body was evidently too much and every touch was like an electric jolt that blinded his eyes and froze his brain so completely that for a moment it felt as though he was lost in a bright, warm spotlight. Tears sprang to the little detective's eyes as the thief rubbed his face into the crock of the little neck.
Kid carefully slipped the boy's pants and underpants off and cupped his erection. Conan moaned again and threw his head back. Using his free hand, kid ran his finger along the detective's spine until it rested just above the boy's entrance. Suddenly he stopped.
"Kaito," Conan whined using Kid's real name, "please."
"I need you to hear this Shinichi." Kaito whispered in his ear, "I will not take you all the way until you are back."
"Hmmm?" Conan shot a questioning glance over his shoulder at the thief.
Kaito licked the detective's neck and lined up his finger while simultaneously gripping the boy a little harder. "Consider it a promise to be back." And he shoved his finger inside the little body.
Conan had to bring both his hands to his mouth to stop himself from screaming as Kid both fucked and pumped him. And as he came in the white gloved hand he knew that his new found lover would keep his promise.
