Avery is asleep, and Jack is thinking.
It's not that he doesn't like fucking Avery, god no it's not that. It's just a different sort of sex. It's about possessiveness and horniness and a burning physical need too strong to have sex on someone else's terms. But Jack's seen how Avery arches into Jake with cries of harder faster more. Sees how he pleads and always gets so into it.
Jack wants that.
He's trying to figure it out, how fucking Avery could ever be normal, and he can't quite come up with anything. He's half-hard, a casual interest sparked by this train of thought and the lube he's turning over in his hands idly, squinting at it in the dim light.
Avery stirs, mumbling slightly, and he's flush against Jack now, almost spooning except It's more than blankets against Avery's legs. Jack is pressed up against Avery's arse, thigh, back. Avery's partially awake now already, but then (to Jack's embarrassment), Jack's cock is against his barely-clad leg, rubbing over thigh and up until Avery is fully awake. "What," he mumbles, surprised. "Jack..."
Jack makes a small noise, an I-don't-know noise, and kisses Avery's shoulder apologetically. "Sorry, I was just...thinking."
"About what?" Avery struggled up onto his elbow, still not facing Jack as he stretched.
"Fucking you," Jack admitted. Avery stilled.
"Fucking me?"
Jack was blushing. "Yeah. I mean, I don't know. Doing it. Normally. Like--"
"Do it."
"E-excuse me?" Jack blinked, not sure what to make of that--even if his cock did.
"Fuck me. Go on, then." Avery ground back against Jack's cock, making the black-haired boy yelp.
"Avery--"
"Fuck me," Avery breathed, clutching his pillow with one hand. He stretched his neck out over the pillow, and Jack kissed his neck.
"Are you sure--" he tried for the last time, but Avery twisted his hips until he was perfectly positioned for Jack, and Jack shut up and uncapped the lube.
Lube one finger lube two fingers lube three fingers lube shoulderkiss cock.
One hand tangled in Avery's hair and Jack left the other on his hip as he eased in, going slowly and actually concentrating on the sensation of Avery around him for the very first time. "Fuck," he told Avery eloquently. Avery pushed back and Jack's grip on his hip tightened. He couldn't believe that he was doing this, really couldn't except for oh he was and it was fucking amazing.
He slid one hand over Avery's hip and wrapped fingers around his cock. Jack was already trembling, and the coolness of the sheets made a faint swishing noise as he--thrust. He was thrusting. Jack was moving his hips and hitting Avery's prostate and it was Jack causing Avery to make those noises, Jack that Avery was begging, Avery was begging and Jack complied with every cry of "more."
When Avery came, Jack's name on his lips and hands red from gripping the sheets, Jack finally slowed his hand on Avery's cock, stopped it and bit down on Avery's shoulder as he came too. "Fuck," he said again, not having found a better word. He was breathless, laughing, and Avery laughed too. Avery tilted his head back and Jack kissed him, hand still on Avery's hip.
"I love you," Avery whispered against his lips.
"I love you too." And then, a little quietly, "I love fucking you." God, but he did. Really did. It was amazing in a completely different way than being fucked, and Jack knew that he would never tire with either.
"Good," Avery said, snuggling back. "Don't pull out then. We'll have another go in the morning."
Jack laughed, and kissed him again.
