Jerk each other off

"Here, you're doing it all wrong." You whisper to him, and then undo your breeches, freeing your cock from it's confines. "Copy what I do."

You place your hand on his tiny pecker and it grows at your touch. It looks comedic. Your fist nearly entirely obscures his penis within it's grasp, but he mirrors you perfectly, grabbing your cock towards the tip. His small hand is freezing, and your hard-on diminishes slightly with the cold.

You begin to jerk back on his dick, and his mirrored movements cause your meat to harden again. He seems surprised.

"Jon." He whispers. "How is yours so big?"

You decide to have some fun at his expense. "Well, the more girls it's been inside, the bigger your little pecker gets. You need to fuck around more, little brother. I happen to have it on good authority that Sansa and Arya's holes are ripe for the picking."

At the mention of your sisters, his little cock shudders between your fingers and strings of cum plop onto the floor in front of him. He groans and you look quickly up to see if his the noise has startled your Father. He appears not to have noticed anything. Bran's grip on your cock has slackened through his miniature orgasm and the cold is having an effect on keeping your dick hardened.

"It feels so good, Jon, but it's starting to hurt a bit. Can you stop please?"
