Kaito ran his tongue slowly along Shinichi's stomach eliciting a muffled moan from the detective. There was a thumping noise as the boy tried in vain to pull at his bonds and only succeeding in bumping the head board against the wall. Kaito continued what he was doing without noticing any noise but the sounds of the boy beneath him. His fingers scratched gently at Shinichi's sides as he nipped and bit at the soft skin of Shinichi's neck.
"I've missed you." he whispered into his lover's ear, "I've missed you so much."
Shinichi tilted his head back to give his tormentor a better angle and grunted incomprehensibly. Kaito smiled at the noise and ground them together, "It's not fair you know." He whined as he ground again, a little harder this time, "I haven't seen you in three weeks because your friends insist on spying on you, not that I don't do the same, but that is completely different." As he was talking he moved slowly down the other's body making sure to push down so that he could feel Shinichi's erection against him thereby causing the latter to whimper at the friction.
Kaito stopped at Shinichi's pants and kissed the skin just above the waist band before pulling them down and licking his head. Shinichi bucked at the contact but Kaito held his hips down.
"Now now Shin-chan." He cooed softly as he nuzzled his face against the detective, "We have a whole three days to play together, let's not rush it."
Pulling himself back up the now shaking body Kaito pulled the gag out of his secret lover's mouth and replaced it with his own. The bound boy tried to take control, but Kaito was having none of it. Normally whenever he wanted to be dominant all he had to do was ask. He knew the detective loved him enough to give him almost anything he asked for, even if he was uncomfortable with it, and Kaito loved the detective enough to do the same. Although sometimes it was worthwhile to cheat just a little bit. Which is precisely what he did.
Reaching back he grabbed Shinichi's erection and jerked. Almost instantly the detective withdrew his tongue and allowed Kaito in. Kaito Kid grinned and plunged into Shinichi's warm cavern. He explored the mouth he already knew so well, running his tongue along the roof and the sides, marking the territory he already knew was his and his alone, and sucked on the bottom lip. Shinichi almost cried as his lover pulled away but continued to place kisses on his lips and face.
"I think that is enough warm up don't you?" Kaito said as he got off the bed and pulled his own clothes off. Getting back on top of Shinichi Kaito lined his entrance up with his lover's erection. Before to pushed down he leaned forward and kissed the detective one more time, "I love you Kudo Shinichi."
"I love you too Kuroba Kaito." Shinichi whispered back before the gag was replaced and Kaito sat down.
Stars filled the detective's eyes as he threw his head back in pleasure. If this was what he had to look forward to for the next three days then he had to let the thief kidnap him more often.
