All he could hear was his own fast breathing, the rapidly beating pulse in his ears, and occasional escaped gasped moan. The room was dark, Jake was naked, spread on his bed, legs apart, hard enough against his stomach for the precome to make a small pool if he didn't touch himself for long enough. Well, not there in any case. His hand was between his legs, reaching down, pressing in, biting his lip against the awkward feel but automatically ridding himself off it by adding another finger, two more fingers and... fuck that was hurting but his cock had jumped and Jake had bucked and he was dimly wishing he had another arm or a toy on hand to be using instead...
His arm was starting to cramp. He gasped, uncaring, fucking himself with four fingers, fingers of his left hand skimming his cock, making his hips jump with the need to be touched - now now finish it now his body said but Jake waited, eyes tearing in the corners but pushing up, up, up with his heels digging into the bed and stretching out the quilt until his hips were arched towards the ceiling and he finally wrapped his left hand around his cock at the same time he hooked all his fingers up and reached and pressed and the world melted out from underneath him as he jerked and bucked hard coming all over his hand and his stomach, not even stopping until he was back flat on the bed, panting, still clenching around his fingers and moving with the few left over waves of pleasure.

It was easy to surprise them, when the time was right, because things like this weren't exactly thought of in relation to him. You might think of it and let your mind jump right to Avery, or Jack though he had winced when asked, but not Jake. Usually. Avery had fucked him before, but he could count the times on one hand. And fisting... it had only happened once. Much to his displeasure, though Avery and Jack didn't know this. They would shortly.
They were all naked (honestly, clothes. honestly.) and Jack and Avery were in a ball at one side of the bed, thinking Jake to still be asleep. Jake grinned to himself, turned away from them, already half hard, then composed himself and straightened his face and rolled over.
Avery made a surprised noise, but Jake stopped him from actually saying anything with a quick, deep kiss and by pressing himself right up against his side, where key things were be made obvious. Jack's eyes widened right along with Avery's, and Jake licked his lips upon pulling back from the other boy.
"Fist me," he whispered seriously, voice low and rough, and watched as looks mixed with surprise and arousal spread across Avery and Jack's faces.
