Coming home after a long day at the bakery, Joel managed to fix himself a quick dinner before collapsing on his couch, distractedly turning on the TV. As he ate, his mind wandered, thinking about everything and nothing. Finally, as he was sipping at his desert wine, he remembered the box filled with vials, hidden under his bed.
Suddenly wide awake and sober, Joel sat straight up, placing his wine glass on the end table beside him. Getting up, he hurried into his bed-room to grab the box, before bringing it out to the living-room.
Opening it, he quickly found the "Male" section, followed by the "Mammals" category. Reaching in, he pulled out several vials, each with a different animal on it.
Looking at them, Joel discarded them one-by-one, until he only had three left.
He could drink part of the Great Dane vial, the largest dog on the planet. His member might enlarge a good bit, but would radically change the shape, even to the point of having a knot.
He could try a Siberian Tiger, one of the largest cats in the world. It wouldn't change his dick size much, but the different shape and texture should be fun.
He could go all-out and just chug part of the Shire Stallion and have an absolute monster hanging off his crotch.
Or, he could do something different all-together.
