The youthening kept on going.
Their penises began to feel the rejuvenating effects of youthening and began to shrink as well, growing more into the proportions of a boy at the cusp of puberty, rather than a young man completely through it.
just as the last of their hair had at last faded into the blonde peach fuzz of preteens or had fallen off entirely to leave them completely bare where he'd once had hair, Paul, Colin, and Barry all released themselves and each one of them ejected a spray of cum that fell to the ground, draining their balls of the last bit of their bodies clinging to maturity and adulthood. Their balls became too young to replenish themsleves, shrinking and growing dormant as they began to pull higher into the sockets they rest in prepubescence.
Their penises shrunk down to the prepubescent nub of all young boys.
however the 3 men did not notice any of this as they basked too much in the sensation of having spent their loads -- doing so had increased the pleasures of getting younger, but had not stopped the pleasing sensations which now, in their post-ejaculation haze seemed even more intense as the feelings were no longer centered in their guts and groins, but beginning to reverberate across the whole of their bodies.
"Oh, we're definitely getting younger, alright." Colin said, his voice becoming higher.
"We're the smallest boys in the world, now." Barry said, his voice cracking as he said this.
"Yep." Paul said, his body beginning to vibrate with the sensations.
He let out a long sigh, which shifted up an octave as his adam's apple shrank into non-existence, returning him to the body of himself at eleven years of age, feeling rather contented and basking in the afterglow.
Soon, he, Barry, and Colin were now 10 years old.
10 year old boys.
3 very small 10 year old boys.
