Ben wakes up in the middle of the night and finds himself still on the couch. He glances over to his roommate, Noah, who is passed out next to him. Noah is wearing only his boxers and Ben can see the modest bulge of his softie. Noah is such a heavy sleeper that there is no risk of him waking up. Ben starts to get an idea and decides to perform his experiment.
He starts talking out loud to the sleeping Noah in playful locker room banter. "Man, you've got a real gym dick, Noah. It's huge even in its flaccid state." He starts to think of a really huge erect size and says out loud the measurement, "I bet it's at least 9 inches long and 6 inches around when it's hard."
To Ben's surprise, Noah sleep talks back to him, "Ha! That's only my flaccid measurement, buddy. Wait till you see it when it's hard." Ben watches in amazement as Noah's growth happens almost like a balloon being inflated with water. The soft bulge in Noah's boxers starts to rise and expand, growing larger and larger.
The growth process is mesmerizing, as the skin stretches and tightens, the veins bulging and pulsing with blood. The head of Noah's cock swells and turns a deep red, the shaft thickening and elongating. Noah's balls, which were previously hidden within the confines of his boxers, now hang low and heavy, swaying with the movement of the expanding cock.
Noah one-ups Ben's suggestion, "11 inches long and 8 inches around when it's hard" he sleep talks. Ben thinks this size is awesome, but it might be too much of a change all at once. He considers allowing Noah to keep that outrageous size but decides it’s best to stick to their original plan, or maybe just slightly bigger.
He talks to Noah, "How about we make it 9.5 inches long and 6.5 inches around when it's hard? That's still pretty impressive." To Ben's surprise, Noah sleep talks, "Sounds good to me." And the growth slows down and stops.
Ben looks at the now sleeping Noah and is in awe of the size of his flaccid member. It is indeed 9.5 inches long and 6.5 inches around, with veins bulging and the head of his cock a deep red. Ben realizes that Noah's member is that size while still flaccid, he starts to feel guilty for performing this experiment, but then he thinks that there's nothing wrong with it, and Noah wants this. He feels a sense of satisfaction, as he falls back to sleep, smiling.
