"Hehehehe!" Arthur laughed as he heard Yukiko's words.
"I didn't know you had a funny side," he said.
"So you find that funny?" Yukiko apparently reacted quite flatly.
"Let's stop talking and move on," Arthur replied.
He kissed her after saying that while Yukiko responded immediately.
Her hands on his shoulders wrapped around his neck while her body came forward enough that her bra-covered breasts pressed against his chest.
Her tongue came out of her mouth before Arthur's. She even managed to lick Arthur's lips.
Arthur wasn't entirely focused on the kiss. His hands moved on her back, caressing her gently.
Then, he pushed her down onto the mattress, still with her arms around his neck so that he fell with her and pressed against her body.
Arthur broke the kiss again and grabbed her breasts, squeezing them gently so that she moaned little by little.
