"Are you done yet?" Larry asked.

"Hold your horses, genetic engineering takes time!" shouted Ludwig.

Larry tapped his foot and rubbed his crotch. He stopped just in time for Ludwig to pop out of his lab.

"Here it is! A Piranha plant that blows for you!"

Larry pulled his member out and placed it into the plant's mouth. He sighed as he felt the Piranha's fat lips begin to blow him…

"YEEOOWCH! LUDWIG! I THOUGHT YOU MADE A DICK-SUCKING PIRANHA PLANT!"

Ludwig laughed. "Well, silly me for forgetting to breed out the teeth!"

"Not funny! I demand my money back for this!"

"Well maybe if you hadn't have rushed me…"

Larry took the piranha plant back to his room. He lay on his cum-stained pillow, staring up at the pictures of hot girls, some Koopa, some human, some of other species. Normally he spend hours masturbating to them, but his cock was too sore now from being bitten.

What he needed was a nice blowjob from a piranha plant that was genetically engineered to have aloe sap for saliva, and large, tight but gentle lips, both of which he had requested of Ludwig to breed into the plant, but also to be toothless…

Wait a minute, he thought. Why don't I just yank the teeth out myself?

Larry dug through his messy drawers for a pair of plyers and squeezed the plant at the stem (it was also bred to be thornless). The Piranha gagged, opening its mouth wide, and Larry jammed a dildo into its mouth to hold it open. He then began to yank its teeth out, one by one, placing them on his dresser with the hopes of making a Piranha teeth necklace.

He noticed that, like a shark, this plant still had several budding teeth erupting on the edges of the sockets where the teeth in current use had been. If the Piranha blowed him tight enough, he would be able to feel them. It wouldn't be painful, he figured; it might even feel kind of good. But not while his cock was sore with tooth marks.

He noticed that the teeth were not made of calcium hydroxyapatite, like Koopa and human teeth were, but of hardened cellulose, like jagged, spade-shaped thorns made of the hardest, most polished wood.

In that case, he thought, a little fire should work.

He got out a welding torch that he sometimes used for forging coins or for lighting bowls of marijuana. He turned it on, and carefully set the Piranha's gums on fire.

He then took his spray bottle that he kept for his piranha plants and sprayed inside its mouth to prevent the entire plant-creature from burning away.

He checked the gums. They were blackened and ashy, all the way down to the deepest roots. They would probably never grow teeth again. Or maybe they would, thought Larry, aware of how resilient Piranha plants were, but not for a loooong while.

He shoved his cock between its flame-chapped lips.

Aaahhh… the slippery aloe sap not only soothed him but made for an awesome lubricant.

The Piranha plant sucked on him like a young mammal sucking on its mother's teat.

The plant made him cum, but not too soon. It seemed to like the cum, and to be thirsty for more. Perhaps Ludwig designed it that way.

Next time, I'll pay him to make me a Piranha weed for me to smoke, he thought.
