Steve was supposed to be watching his brother while his parents were out doing errands but had been playing games in his room. The sound of crying forced him to stop his game and head towards the living room where Henry had been playing. Seeing Henry on his hands and knees surprised Steve as he hadn’t been seen crawling yet. Henry had been fed right before their parents had left so Steve thought that the crying must have been because of a need for a diaper change. Dreading having to change the diaper on his own Steve Picking Henry up and took him over to the soft changing mat next to the fresh diapers. Laying Henry down on his back Steve could now see how the diaper was straining to remain closed around its contents. Steve was confused at the sight, not knowing how the baby boy could have filled the diaper in such a way. Henry for his part had stopped crying while being carried to the changing mat but now that Steve was no longer doing anything and just staring he began to cry again as the diaper continued to dig into his sides. Called back to action Steve took a deep breath and went to remove the diaper.
Steve quickly pulled the sides off which allowed the diaper to flip down and expose the bare crotch of the serum enhanced child. What was exposed left him baffled and perplexed. The few other times Steve had needed to change Henry’s diaper he had tried his best to not pay attention to the oddly large genitals of his younger brother that had been only a little bit smaller than his own even though he was 10 years older than Henry. Now it was impossible to ignore as the massive cock and balls that had just been released from the diaper dwarfed his own in every regard and don’t appear to be hard in the slightest.
Steve looked at the mighty meat that his baby brother was packing and thought that it had to be fake somehow. Reaching forward he poked at the fleshy appendage trying to gauge its authenticity. It soon became abundantly clear that his brother’s new cock was indeed real and fully functional as it was becoming erect from the feeling from Steve’s hands running over it. Steve guessed its size to be at least a foot long and its balls to be the size of golf balls. Steve had gotten a little lost in the examination of the unreal cock that he had gotten his face rather close to Henry’s flared head were a bead of precum was forming right before his eyes. Before Steve knew what had happened Henry had grabbed his older brother’s head and pushed it down onto the waiting cock.
It filled Steve’s mouth and tried to enter his throat but Steve pushed back, but found Henry’s strong grip on the back of his head preventing the full removal of the meaty invader. Steve continued to try and push back but was finding his efforts counter productive as the unnaturally strong Henry began forcing his cock deeper into the older boys mouth. As the head was forced down his throat Steve ceased resisting and began sucking and licking the cock in the hope that it might cause Henry to cum and become soft.
Is Steve successful at pleasing the massive cock or does someone come to his rescue?
