Chad isn't (hasn't) that much of a dick after all.

You go take a leak and notice a long curly pubic hair on the toilet seat. Your sister is clean shaven down there, your parents would have cleaned after themselves and you were away for a week, this only leaves Chad the dickbrained boyfriend of your sister.

You pick it up to put it inside of the compartment of the voodoonator 2000, you make sure to wash your hands after that.

"Let's get a look at him, I'm sure there are ways to mess with him. He is so proud of his body and how much of a stud he is! " you tell for yourself.

You turn the device on and are welcomed by a view of Chad, naked!

"Wait, this thing is broken already? It should show his clothes." you mutter as you push the clothe button with no effect, the device is cool and your are happy of the changes you made on you but if it stop here it would be a lot of cash and efforts for little results.

Unless..... unless he is actually naked. Given the usual smell of sweat he drags around there is little chance that he just took a shower in the middle of the day. This leaves the obvious, he is banging your sister or about to do so.

His erect cock on the picture is a good hint about that. It infuriates you, he is barely bigger than you despite his endless mockery in the showers at school (and that's barely bigger than you were, your new dick beats him easily) the only difference is that his is nearly the same length soft and erect while your grows a lot and look a lot smaller without an erection.

You click the groin of his picture and look at the various sliders and menus.

"Well, he's so much of a dick that I will be helping him and making her dump him is the best thing I could give my sister. " you rationalize.

You use the sliders to set his new size to 2.5 inches erect, 1 inch soft. You open the sensitivity setting and see that it is already very high, could he have premature ejaculated issues? You set it to the max, any stimulus on his dick will make him cum instantly. A few adjustments to his balls will make sure they can deliver each time.

"Good luck jizzing in your pants all day and keeping a girlfriend with your micropenis, morron. " you shout as you look at the results.

It should change their afternoon schedule a little bit.
