This would not leave me alone today. I promised myself that I would type it up if I finished the laundry, which turned out to be a great incentive! It was supposed to be cute, happy, & fluffy, but it turned out kind of sad. There might be a second part - I need to think on it for awhile. I can't see myself leaving it like this though.

The sound of giggles outside the door to his quarters confused Optimus Prime - he thought the children had gone home hours ago. At the soft knock, and more giggles, he got up and answered the door. He was surprised to see his second in command standing there, giggling. "Hello, Arcee" he said, as his sensors registered a considerable amount of high-grade in the air.

"Hi Optimus" she practically purred, as she sauntered into the room, lightly running her fingertips over his lower arms. She giggled again as she walked around him, while he could do nothing more than stare at her in shock. He wondered where had she gotten high-grade, and why she had overindulged.

"Let me take you to Ratchet" he said, as she continued to stroke his arms. He tried to convince himself that she wasn't having an effect on him, but he had to admit he was enjoying her touch. He couldn't allow this though.

"Been there, done that" she said with a pout on her face. "He told me to go to my quarters and sleep." She was so cute with that look on her face. His own emotions were getting harder to control. He needed to put a stop to this, before they both did something they would regret.

"These are not your quarters, Arcee."

"I know. I wanted to see yours."

"Why?"

"Because you're here." Suddenly, she jumped at him, wrapping her arms around his neck, and pressing her lips to his. He caught her instinctively, losing his balance and stumbling backwards until he was sitting on his bed with her in his lap. He groaned and kissed her back for several moments before his processor caught up with his actions; he stopped and pulled away.

He couldn't think with her hands stroking his head and shoulders. He caught them with his and looked into her optics. "Arcee, we can't do this." The disappointment in her eyes was spark-breaking.

"I know." she whispered. She laid her head on his chest where she could hear his spark pulsing. He still held her close, forcing his own emotions and physical reactions back under control. When he looked at her again, her optics were closed; she was sleeping.

He savored holding her for a few more minutes before picking her up and carrying her back to her quarters. He laid her in her own bed and pressed a kiss to her forehead. He whispered "someday, I promise" into her audio receptors, then retreated back to his own quarters.

I hope you enjoyed it!
