Nut filling son Family's New Shrink Ray chapter 12 by copier · original author: teunen

His dad moaned, the intense feeling of his son trashing and hitting the inside of his urethra. What a pleasure! Derek was inside only with his upper half, but that was quickly solved when his dad grasped his dick with his right hand, positioning his thumb right over his son's kicking legs, and the pushed down. Derek was not even a bulge in his dad dick, now stuck in the head, right after the slit. The pulsating wall around firmly keeping him from moving to much, preventing any escape.
Steve savored the moment for as long as he could, then start masturbating properly, moving his hand up and down the shaft, while the other was stirring the semen awaiting in his nuts.
He applied more pressure moving his hand down than up. Pushing his son down, seeing now a bulge forming under his head, his own son, heading to the balls that made him.
He keep stroking vigorously until Derek passed half the length of his dick, than moved his hand to his nipples, playing with them, staring intensely at the bulge in his dick, lodged, trapped here for as long as he wanted.
That's the reason he didn't shrink the shrimp smaller, he would have traveled all the way to his nuts to easily, without even stroking, only by gravity. But no, he was his fucking son, and he wanted complete control over him.
He starter stroking again, slowly, feeling his son inside his dick. He wanted to cum so hard, but he keep a hold of himself, Derek was destined to return to the nuts that made him, and that was it. He started stroking his cock with the that intention now, the bulge traveling down at a steady speed, toward the base of the snake that has just swallowed him, disappearing inside his dad's body. Steve knew what was coming now, and prepared himself. Then Derek reach his dad's prostate.
Pure bliss run across his body.
:- YES DEREK... THAT'S IT... OH FUCK THAT'S THE SPOT! HIT IT! FUCK HIT IT!
Derek didn't really need any encouragement, he was hitting everything he could from the start. He screamed, not having learned from his previous mistake, ending up swallowing who know how much of Steve's pre. Then he felt a huge force pushing he down, and down, and then nothing but his dad's moans. Shit, how long was he gonna keep this going? He was enjoying it, no doubts. Still he was his son, not a toy!
Derek tough drifted to after this hell, when his dad would grow he to its full size. I'm going to show you Who is in charge asshole. He tough, I'm gonna steal your shrink ray and make you an ant at my feet, then I'll be moaning at you bitching around in my dick. Heck, if I figure out how the improve my nuts to I swear I'm gonna keep you inside weeks! These though caused his own dick to get hard, pressing the inner wall of his dad dick. Then he felt the pressure being applied again, and again he was being forced down his dad length. And while his dad was stroking himself, he was also helping his son jerking off, causing him to orgasm, sending his seed all over. After a while he couldn't feel his dad's hand anymore, still he traveled forward. The tunnel changed at one point, becoming more soft. The he heard his dad talking. "Fuck, I hit his prostate!" Judging from his dad moans it really has to be an experience. Here he have an idea, what if he made his dad come before he reach his nuts? He starter trashing like crazy, his dad's moan louder and louder.
:- FUCK SON STOP ... OOH... YOU'RE NOT GONNA REACH... FUUCK... MY NUT IF YOU KEEP... KEEP GOING LIKE THIS.... OOOH YES...
Derek tough he has outsmarted his dad, it will not be a happy escape, knowing he was going to be shot out from a cock. Still better than spending Who know how much time in some nuts.
Steve felt it coming, there were nothing he could do to stop Derek, so he grabbed his dick with both hands, he wasn't going to let his son out so easily.
Derek felt it coming too, its escape rout was reaching for him, cum flooding from deep within his dad, hitting him hard and pushing he back. But not back enough, something was preventing him to move with the cum, the passage he used now being constricted, to small for him, but not for the cum rushing around him. Fuck, he tough, dad let me out!
Even with both hands, Steve's cum reached the head and come out, not like a cannon, but more like a fountain. After the stream subsided, Steve move his hands from his dick, a bit sore for the treatment, and take deep breath, riding what was left of his orgasm. After some minutes, he started playing with the cum on his abs, enjoying the knowledge that his son was still within him, smiling, feeling some movements at the base of his dick.
With a hand he grabbed his tool again, and started massaging his son toward his fate.
:- OOH SON, THAT WAS AMAZING. REALLY... BUT YOU TRIED TO ESCAPE, IT'S NOT GOOD DEREK. I'M GOING TO PUSH YOU ALL THE WAY TO MY NUT. YOU KNOW, I WONTED TO LET YOU IN HERE ONLY FOR THIS SESSION, BUT YOU'RE STILL IN THERE, AND I ALREADY CUM, SO I THINK I'LL KEEP YOU IN THERE TILL MORNING.
Steve could now feel Derek passing his prostate. YOU'RE ALMOST HERE NOW, ONLY A LITTLE PUSH AND... OOH YES... Derek fell from the passage, head first in the little cum remaining in his dad left nut. To tired to try anything, he simply lay there, hoping his dad would free him soon.
