After a few weeks of fiddling with his phone, Killian Jones eventually got a serviceable understanding of what he could do with it. He knew what buttons called people, what buttons sent digital letters to people and what buttons took photos. He knew his own phone number, Emma's, Henry's and even the in-laws so he could talk to them whenever he needed.
He'd never actually done any of that mind. He couldn't bring himself to. The people who he could talk to via the gadget were those that were already around him, he didn't see the point of conversing through a screen if he could just walk down the street and have a conversation face to face.
There was one thing however which completely dumbfounded him even in concept. An idea that his wife posed one night after a particularly rough but entirely boring tumble beneath the sheets.

"sex-ting"

"so..." he said, checking he had it right in his mind "I point the phone at my... privates... and take a picture?"
"Yep. It's that simple, then you send it to me. Or... you know, whoever. But I'd hope it would be me"
"And what... you... you-you look at it? For what? For fun? To do a check up?-"
"Some kind of fun." Emma smirked, rolling over onto her belly to reach for his cock. As her fingers brushed it he giggled and felt the blood rush to that area, with a little tingle at the end.
"Oh-ho-ho I get it Swan. I get it. Let me try it now"

At this he sprung out of bed and dove into the bathroom. Once he'd locked the door behind him, still aware of Henry's presence, Killian pulled his trousers down, and glared at his genitals. With one hand he opened an app on his phone called "Snap Chat" for the first time in his life and pressed the shutter button. A click notified him that he'd taken a picture.

Back in the bedroom Emma roared with laughter "KILLIAN! KILLIAN! I've only got your face!"
"Oh." the pirate said, disappointed. "Sorry Swan"
"I don't care. I prefer the real thing anyway.
