Amberton Portal 1/Jack/Risk it, and masturbate in the shower
Jack thought to himself, "I really don't have time for this crap, I'm hopping in the shower, and if I can't rub one out with some soap to lube me up, well, a freezing cold shower will settle things down enough for now."
Jack got to his feet, his lean form etched with sleek muscles after his light morning workout, his big dick standing out like an exclamation point to emphasize his maleness. He'd never get his shorts on over that boner, so he scooped up the shorts and tossed them in the hamper, then padded naked over to the door to the bathroom. As he did so, he thought he heard a noise from the bathroom, and worried for a second that little Franky was up early and about to make a pest out of himself, but when Jack cautiously poked his head around the door to look, the bathroom was empty. Good!
Jack's dad, Fred Lancer, owned his own business, and while they weren't exactly rich, they had a nice house. Jack's and Franky's rooms were spacious, with walk-in closets, but they didn't quite merit having a private bath in each one. Instead, there was one big bathroom built between them, with a door to each of their respective bedrooms. There was a lock on the doors, obviously, but Franky had suffered some bedwetting incidents a while back, and their Dad had laid down the law: Franky got free access to the bathroom, no if's, and's, or but's. The precocious eight-year old had chosen to use the awkward situation for 'humor' more than once. Ha, ha.
Jack padded naked into the big bathroom, tile floor cool against his feet, his massive boner leading the way to the shower. Jack sort of hid himself behind the shower curtain, in case Franky popped open the door like a jack-in-the-box to surprise him...which the little shit had done before, laughing all the while. The water started to warm up slowly, so Jack decided to grab a towel before he got in.
Jack padded over to the cabinet and got out a towel, and was struck by a sudden thought.
The towel cabinet was all the way across the bathroom from Jack's entry door...which meant he was right next to Franky's door. It would be easy to just reach out and open that door a little, maybe poke his head into his little brother's room and... you know. Be sure the kid was still asleep.
Slowly, almost against his will, Jack found himself turning to look at the doorknob to open Franky's room, maybe two feet from his rock-hard dick.
Jack's heart lurched in his chest, and his dick drooled a heavy stream of crystal-clear pre-cum at the thought of slipping naked into Franky's room. Why, anything could happen.... Jack blinked and shook his head, trying to banish sudden images of cute little Franky buck-naked, kneeling on his bed, his cute little ass wide-spread as Jack fucked his big, hard, cock slowly and greasily out of sight up his little brother's asshole...
Sure, why not, sneak into your little brother's room, what awful GAY AS HELL things could go wrong?
Ewwww, no way! Get in the shower and rub one out like a normal horny teen! Cripes, what is WRONG with you?!
