It was a very big box.

Dave walked all around it, grimacing at the strange mixture of exasperation and curiosity the box invoked. It was a good four feet on all sides, a big corrugated-cardboard cube sitting smack in the middle of his office. UPS had evidently delivered it while he was up front, helping the cashiers with the new pricing on the frappuccinos.

It was clearly personal, or else it would have been delivered to the storeroom. The trouble was, he didn't remember ordering anything from Metaboy.com.

And if he had, he certainly wouldn't have had it delivered to the office.

Dave chewed a knuckle, wondering whether to open it. With sudden decision he strode over to the office door and locked it. He returned to his desk, grabbed a utility knife from the drawer, and sliced through the packing tape across the top. He set down the knife and opened the flaps anxiously.

On the top there was a packing slip. It looked like a million other packing slips he'd seen as a coffee shop manager, but the products it described were decidedly unusual. He glanced through them—"Classic II Arms"(4)... "Firm Footing Feet"(4)... "Sensations Penis Variety Collection" (2)... "Grow-Me-Gradual Supplement Pak"... "Brooks Brothers Custom Enhanced Dress Shirts and Slacks Set"(6)..."Introductory Video"...

There was more, but the words were blurring. He realized his mouth was dry and swallowed nervously. His hand was shaking slightly, making the paper flutter lightly.

Slowly he set the paper aside and peered into the box, not without trepidation.

He reached in and pulled out a long, narrow bubble-wrap sleeve that clearly contained within it a human arm. He peered at it through the plastic and felt a queer thrill in his stomach. It was his arm--his coloring, his tight, not-too-big musculature, his longish fingers.

Cautiously, and with great care, he withdrew the arm from the bubble-wrap sleeve. He touched the skin: it was smooth and firm yet yielding, just like his own arm. Oddly enough there was a sticker on the side with brief directions: remove the seal (there was a circle of plastic on the side of the shoulder, where the arm would join the body) and place directly behind existing arm (get a friend to help if necessary). Hold for fifteen seconds and release.

Before he even realized it Dave had whipped off his tie and blue dress shirt and was peeling the plastic off. Without looking at what was inside, he reached back with his left hand and, a little awkwardly, pressed the shoulder against his body, behind his existing right arm. He counted to fifteen in great agitation, his stomach flapping madly around inside his tight torso.

Then, cautiously, he let go.

He ran his finger around the new shoulder. It was seamlessly sealed to his new body. He glanced down, and he could see no juncture.

The arm hung limply for a moment and he experienced a split second of pure horror at the thought of this lifeless limb joined to him—then, suddenly, with a warm rush, he could *feel* it. He let out a relieved gasp. Blood was coursing through the new arm, and he could even feel his shoulder slowly restructuring to complete the links to the new arm. After a moment he could make a fist with his new right hand. He pressed his arms against each other, feeling firm muscles against firm muscles, and he realized his cock was very hard in his pants.

Five minutes later he had attached a left arm for symmetry and was digging through the box for more.

He found the two packages of penises. There were six in each set, ranging in size from a little larger than his current 7 inches to more than twice that size, some of moderate girth and some the size of a salami. Excitedly he pulled the biggest ones out of each package, removed the plastic seals, and thrust them down in his underwear before he could change his mind. After fifteen second he could feel they were attached, and before a minute had gone by they had hardened into rock-hard missiles in imitation of his own original cock. Then, to his astonishment, his original cock began to inflate, gradually matching the size of its new brothers. As it reached full size and hardness Dave came, suddenly and spastically, out of all three cocks, in an orgasm so intense he nearly collapsed to the floor.

He was still seeing spots before his eyes when he heard insistent knocking. "Mr. Logan?" called a voice from outside.

Dave looked up in wild-eyed terror, his heart stopped in midbeat. What had he been thinking? He was so screwed!
