Prompt: "Person A of your OTP lists all the pet names they have for Person B. The list never ends."
Wheatley was quietly resting with his head on Chell's lap while she read a book. At some point, she had begun to also stroke his hair, causing him to unconsciously begin purring. He would always curse his machinery and mechanisms for doing something like that whenever he got affection of this nature, but he didn't mind it all that much.
And neither did Chell, as she continued to gently run her fingers through.
"Thank you, sweetheart," he murmured, which caused Chell to smile slightly.
"How many names do you have for me?"
Wheatley cracked one eye open to look up at Chell, who was closing her book and looking at him while she waited for him to answer.
"Well," he began, "I've got luv, obviously, that's a personal preference, but there's dear, and sweetheart, darling... that's the main list, but there are others you hardly hear.
"Then you've got sweettart. I said that only once, you know, but it still counts. Then there's honey, which I don't call you as often as I should... angel. Angel is one that I really should be calling you more often. Along with dearest. That's still different from dear. And then there's the ones that I haven't had a chance to call you yet but I'm still waiting to do so."
Chell raised an eyebrow, waiting for him to continue. These she had to hear.
Wheatley gave her an embarrassed glance, like he didn't quite want to tell her these yet, but she wanted to hear them…
"Pretend you're calling me all of them now," she said, and that was all Wheatley needed.
"Prepare yourself, luv, some of these are going to get a little ridiculous, but I hear them while I'm out and about or I read them or see them on TV and-"
"Wheatley."
"I'm getting to it, keep your hair on, luv! …I heard someone calling their significant other 'beloved,' which seemed so nice, and hunny bunny, which I wasn't too sure about, honestly. Then you get into the royalty ones like 'my princess' or 'my queen', and while those are completely, one hundred percent true, I don't think you would like being called those.
"Buttercup. My sunshine. Treasure, now I liked that one a lot. Joy of my life. Daisy. Cutie. Cutie-pie. …Sometimes I hear people when I'm out and about talking about someone being the 'better half' and honestly, that's you, sweetheart."
Wheatley looked up at Chell, who was blushing red from all of Wheatley's names and his affection. Smiling, he reached his hands up and pulled her down into a kiss.
When Chell pulled away to resume reading her book, Wheatley settled back into a comfortable position, whispering, "And you're my whole world."
