Warning, this is pretty much pure smut, you've got to expect that for there are some pretty sexual themes in here, so if you don't like read the next chapter. So here's some amateur smut, written by me.
Dave stride is now fifteen years old, and as such his sex drive has risen. His door was locked as he types on his computer. He looks for "ways to please a troll" Just in case Karkat ever wanted to do, the do as they say. He places his head phones onto his head. A voice booms into his head.
"To please a troll, in which you should only do for your own sake." Dave rolls his eyes on that comment. A troll is brought into the screen, completely naked, and placed onto a table. The troll lay onto the table. "You will be able to tell when a troll is in need for sexual attention when his bulge..." she touches a blue tentical like thing that squirmed around. "is unsheathed like this." she rubs the bulge as Dave bites his lip pressure building in his pants. The troll on the screen gasps softly rubbing into her hand. "Not as likely, but some trolls prefer their nook to be played with." she inserts a finger into a blue hole, as the troll gasps harder. Dave rubs his crotch, soon unzipping and grasping his dick. "Circular motions are their best friend." The troll whimpers bucking his hips into the woman's hand. "Pressing against the walls can either be extremely pleasuring, or it doesn't do anything." she obviously did as she said, for the troll moans loudly, Dave rubbed himself faster trying to keep in a moan. "Now, unused trolls are not used to a human penis, for they were not built for that, as you can see a bulge is thinner at the top and thicker on the bottom." She rubs the troll's bulge again. "but a used troll, very well could be. So if you want to please you're troll the best you can, you must prepare them, if you are male, by using you're fingers. start slow as I did, use one finger going to two, insert a third..." She did the actions as she said them, the troll was squirming against her hand and moaning loudly. "If you have a dildo..." She pulled out a blue plastic human penis. "You can slowly introduce them to the human penis" she inserts the dildo into the troll, in which made the troll moan even louder, whimpering back. This proceeds, she manipulates the trolls nook with the dildo, rubbing his bulge as well. Dave rubs his own penis harshly biting his lip harder. "to catch their genetic material, you will need something big, such as a bucket." A man brought a bucket out placing it under the trolls bulge as she turns him around. The trolls whimpers and moans until the troll cums with a big bang. Dave shock ran through him cumming as well. It was so much. Dave thinks after he cleans himself.
One of his online friends, Jade, began to pester him. She always had the perfect timing, as if she knew when was the best time, and just pestered. Dave pestered back.
