Aiden can't help but steal glances at Jeff's naked lower body. He's skinny, his butt cheeks are firm, and Aiden has never seen teen dick before. He'd tried to avoid staring in the shower, but seeing how big Jeff's boner was, and how much hair he had, it was hard not to look, and apparently Jeff had caught him.
It hadn't been Aiden's intention to leave Jeff naked all day. It'd been a decision made in anger, and as soon as Aiden left the bathroom, he'd expected Jeff to apologize, or at least demand clothes again. Aiden would have given him some, even while angry. He's surprised how committed Jeff is to pretending he doesn't care about being naked. Teenagers are weird.
Aiden decides to get some answers, he doesn't want to waste his entire two weeks. "So, how long has it been since you lost your limbs?"
Jeff winces. "All my life," Jeff says. Aiden quickly looks down and sees Jeff's dick enlarging.
"So it's some kind of birth defect? What's the name of it?"
Aiden sees Jeff looking up, and he wonders if Jeff is trying to think of a lie.
"It's called...none of your business," Jeff says. "Just watch the damn show."
Aiden decides not to press things while Jeff is mad at him.
Seeing Jeff crawl around naked throughout the day turns Aiden on. He doesn't know why he feels so good, but when he is standing, fully clothed, with the older teen crawling around, butt in the air, asshole exposed, it does things to Aiden.
After dinner, Aiden finally can't stand it. He goes to the bathroom, and jerks off, and all his thoughts are of babysitting Jeff, and Jeff begging Aiden to give him clothes, and Aiden making Jeff lick his feet, and Aiden gasps and catches his little shot of cum in a bit of toilet paper.
Jeff, despite his current predicament, still has more life experience than Aiden. When Aiden comes back out to the living room and sits next to Jeff, he won't look in his direction, and Jeff sees Aiden's face is flushed, and with the kid's pale skin, he looks very red.
Jeff once again remembers the pleasure denied him by his missing hands, once again giving him a boner. He glances over at Aiden again...and catches Aiden looking at his dick!
They both look away quickly, ashamed for different reasons.
After some awkward silence, Aiden finally says something. He pauses the TV first.
"Jeff, I'm really sorry you don't have any hands, or anything," Aiden says. "I know why you keep getting boners."
Jeff groans. "Stop, I don't want to talk about this."
"I get it Jeff," Aiden says. "When you have hands, there's things you can do about it, to keep it from getting hard all the time. Do you know about that?"
Jeff's boner won't go down. Apparently even someone talking about his inability to masturbate is part of his fetish. Why me? Jeff thinks. "I know about masturbation, you don't have to tell me how good it feels. I wish I could still-I mean, I wish I could, but I was born like this, and stop making me talk about it!"
Aiden caught Jeff's slip up. He was certain Jeff was about to say 'I wish I still masturbate', or something like that. He was lying. Maybe Jeff's parents think this is normal, but Jeff doesn't.
Aiden sees that Jeff is crying now, face reddening. Aiden feels like a jerk suddenly, and he hates being mean to people and hurting their feelings. Maybe in his fantasies he can be mean, but this is real life.
"Jeff, I'm going to try something, don't be mad," Aiden says. He reaches out his small, delicate hand, and grasps Jeff's boner.
Jeff looks at him, eyes wide, but he doesn't tell Aiden to let go, so Aiden takes it a step farther. He starts to masturbate Jeff, at first doing it with a few fingers, like he does his own, but Jeff's cock is so much bigger that he switches to using his whole hand. Jeff's penis is hard and warm and it feels so strange to Aiden, but Jeff closes his eyes. He's gasping, and Aiden sees a look of pure bliss on Jeff's face.
Aiden grins, and decides to see how far he can push this. He grabs Jeff's hairy balls in his other hand, and says, "I'm sorry you have to crawl everywhere, and get showered by me, and eat off the floor."
Jeff starts squirming with excitement, and Aiden is sure he's right. Jeff is turned on by being reminded of his humiliating circumstances.
"And you had to be naked all day," Aiden says, and he's panting from exertion now too, hands getting sweaty as he jacks off the teenager. "I can actually even see your butthole right now."
Jeff gasps and shoots a massive load. Aiden wasn't ready for it, and now it's too late, Jeff's cum coats his hand and Jeff's body, and Aiden uses his free hand to catch the rest of it while keeping up his hand action.
When nothing else comes out, Aiden looks at how much cum Jeff produced. Aiden didn't realize there could be so much! He only produces a tiny amount when he does it. If he starts making this much when he's older, cleanup is going to be difficult.
"I'll clean you off," Aiden says. He grabs tissues from the end table, and soon has both of them wiped up, but Jeff is still a little sticky down there. Aiden washes his hands, and comes back with a wet paper town to wipe Jeff down even more.
"Thanks," Jeff says, still looking embarrassed, but he makes eye contact. "I really, really needed that."
"No problem," Aiden says. He feels proud of himself for doing the right thing. "Do you really get turned on by having to crawl everywhere?"
"Ugh, too far, Aiden, god," Jeff says. "Hit play already."
They go back to watching Avatar, but their relationship has changed.
