Roy points the remote at the laptop, then sheepishly down his pants. His genitals instantly feel different. Inspecting them in the mirror, his cock began to stiffen, but... it didnt grow in size. Rather, it had become smaller and now had to become erect to match its original size. Moreover, the skin felt a little more rigid and smooth. As he lifted his cock, he made out a tattoo on the underside, only readable if he aimed his penis all the way up.
"Bad girl", it read, in a gothic font he thinks wouldn't be out of place at Hot Topic. And as he fondles it more, something seems to flip on like a switch, and his penis begins to... vibrate?!
Roy can't help but shudder as it begins to vibrate sensually, and he releases it as he grips the bathroom counter, "o-oh fuck... am I a bad dragon product now?" He quips, grinning in ecstasy as his cock vibrates without end. After a while, all desire to turn it off leaves his mind as he hunches over the counter for the next several minutes, just enjoying the vibrations running through his body until finally, the familiar rush washes over, and Roy ejaculates onto the floor. The vibration powers down, and he feels utterly spent.
A little bit more poking and prodding, and the underside of Roy's cock plops open like plastic, falling to the ground along with a couple batteries.
"It... it takes batteries," he says to himself, "Christ, if only it were--"
And then his junk pops off his crotch, leaving him with only a power outlet like one might expect to slot the power cord into on a laptop.
"-- portable," he finishes. Strangely, he could still feel it as he rolls the cock over in his hands, "Well, guess I'll slot some new batteries in it."
