Late at night, roughly 3 AM, you were jolted awake by a resounding *CRACK*, bolting upright in confusion it happened once, then twice more before you felt yourself briefly plummeting. Seconds later realization came as you though "Holy hell, did the bed just break?!" you said to yourself. Standing to look around you were founded with your answer and to your absolute disbelief the culprit as your dad, now doubled in size, snored blissfully away. "Shit, shit, shit, shit, shit..." you said pacing, "This isn't real, it couldn't be real!" but there he slept, with a hand on his dick and stupid grin on his face.
"Nope, nope, nope, nope, nope, nope, nope can't be real!" you said storming into your father's bathroom "I must be dreaming!" Several minutes of face washing and nope-ing later you heard some more painfully real creaking sounds and after a couple minutes deliberation decided to dare a peek. What you saw shocked you in a plethora of ways as Shawn's hulking body had now grown large enough to reach from one of the room to the other. "Oh...crap..." you said, realizing that his body was now blocking the door "...now I'm stuck..." As you stood, brain floundering, you witnessed time after time that if he was...fondling himself there seemed to be some kind of growth, "Great...the horniest man ever appears to grow when he's horny, really fucking cute universe." you thought at least he's not doing it right now.
Deciding that, despite the risk, it'd probably be prudent to try and wake your father up you moved near his head and started calling out his name, but to no avail. "Shit, he sleeps like rock." you said moving to instead trying to jostle him awake, but to your chagrin he was, again, sleeping far too soundly and was now far too heavy to be shaken effectively. "Damn..." you said to yourself "if only there was something more sens- No!" you yelled at the forming idea. "I refuse to touch that!" you argued with yourself, babbling like a madman, "But it's the only way." "Says who?!" "You know you want to." "I do not!" "Then why are you so upset?"
After five minutes of silence you resigned yourself to try that, moving to Shawn's enormous form you carefully stepped on to his pelvis and nearly lost your balance, the sensations sending quivers throughout your father. "Well..." you sighed, standing in front of a colossal dick that was only a few inches shorter than yourself "Here goes nothing." With an extremely awkward movement you sort of shoved the massive dick, half of you wanting to hold on and half of you wanting to have touched it in the first place. Then with a tremendous shudder you could feel your dad expanding again, his skin stretching, bones clicking, and the floor beginning to groan as his body now slid up the walls towards the ceiling and the previously shorter penis grew to be approximately two heads above you.
Now crestfallen, it appeared that you had only made the situation worse until Shawn began to stir amongst a fir of snorts and yawns. Your elation was brief though as he opened his eyes slowly once then sharply and fully awoke a second time and asked "Caleb? Why are you the size of my dick?" Pointing out it'd probably be more accurate to say his dick was the size of his son, Shawn realized the state of the room that currently, desperately, held him. Explaining the events of the night and the overall situation took some care, tactfully making no mention of handling your father's equipment, but when you'd finish you pleaded with him that, however so, he had to try and stop...
