As soon as Peter realized where he was, he was so horned up at the sight and feeling of the huge cock Allen had given him that he really had no choice but to jerk himself off. It was awkward yet incredibly erotic having to use 2 hands to jack off the huge cock he now possessed; but it didn't take Peter long to cum once he got a rhythm going. The feeling was so intense...it was way beyond any orgasm he ever had before, but when he began to shoot, he only shot the same amount of cum that he normally did even though his orgasm actually lasted for almost 10 full minutes! After the first few shots, his giant cock just kept firing even though no more cum was coming out of it.
When it was finally over, Peter collapsed naked onto the bed as his thick, 3 foot long cock became soft and shrunk down to a flaccid size of 20" long with the thickness of a beercan.
Allen had secretly been observing Peter the entire time just because he thought it would be hot to see what Peter did once he realized he was by himself and was probably going to be stuck with that huge cock of his for quite a while. Now after seeing what transpired, & how much Peter seemed to enjoy himself, Allen decided that before he left Peter completely alone for the rest of the day, he would give him something even bigger to deal with! With that thought Allen telepathically set his plan in motion by willing Peter to fall asleep immediately after he had collapsed naked on the bed and after having him also pull a sheet up over his lower extremities with the top resting at his waist. Allen was going to make Peter sleep soundly for a couple hours; but as he sleeps, Allen will make Peter have several growth-related dreams/nightmares; and then once Peter wakes up, and tries to roll over, stand-up or even just pull the sheet off himself, he'll suddenly realize that they weren't just dreams afterall!
So now as he slept, Allen arranged for Peter to start dreaming about his giant soft cock...in his dream, he'll watch it as it slowly grows hard again to its full freakishly huge size. Then as he reaches out to start stroking it Peter will wonder just how big his balls would actually have to be in order for him to shoot full streams of cum for the entire 10 minutes or more that his huge cock now forced him to do, even though his balls couldn't keep up. With that thought he'll see & feel his plump little grape-sized testicles begin to swell and expand underneath his huge 3ft cock...growing so big that they gradually start pushing his legs further apart to make room as they pass tennis ball, then softball size; and then continue growing beyond the size of basketballs until they actually look like 2 gigantic 'prize-winning' watermelons stuffed into a huge stretched out beanbag chair-sized scrotal sack!
Staring in shock & amazment as this happens, & then suddenly realizing that he's obviously just dreaming, Peter will decide to continue jerking off just so he can see what massive balls like that would actually do & feel like if he really had them. To the surprise of Peter's sleeping mind, as he continues to stroke his giant rock-hard cock, instead of getting closer to cumming, he'll feel it growing softer & heavier in his hands with each stroke until it's entirely back to a flaccid state again heavily draped up & over his now massive testicles. It's then that Peter will be shocked to realize that while his cock did return to a completely flaccid state, it didn't shrink at all in size...meaning that his cock is now 3ft long and as thick around as a 2-liter bottle of soda...SOFT!!!
As Peter's mind tries to grasp that concept...& he tries to imagine just how insanely huge he would probably be now if he got hard; he'll also briefly wonder if his monsterous balls will still be big enough to support a cock that's even bigger than the one Allen gave him. In answer to that question, and to Peter's horror, he will see & feel them stretch & expand out & down even further; causing him to finally start waking up from his dream/nightmare state...feeling incredibly relieved that it was all just a bad dream...that is, until he discovers that his 'bad dream' has actually come true!!
