Riku loved being kissed. He loved when the Prince tentatively put his hands on him when they were in the bath, he loved when the Prince's eye lit up to see him, he loved the way the Prince whispered 'goodnight' and 'I love you' as they fell asleep. But he especially loved being kissed. The press and push and pull of kissing, the many things kissing could communicate, from 'hello' to 'I want you.' The comfort of kissing, but also the excitement.
When Riku had climbed into their bed tonight, knowing that they were going to try new things together. He'd already been half turned-on by the very knowledge that they were going to explore each other in intimate ways. But the soft slide of the Prince's tongue into his mouth made his body tremble, and a wave of arousal wash over him.
Riku moaned softly against the Prince's mouth, tightening his hold on the other young man, pushing the Prince's thin shirt up just a little so that he could touch soft, warm skin.
