The door suddenly opens and Adam thinks that Mario has finally returned. He's surprised to see his friends Stan and Kyle instead. "Oh shit!," Adam thinks. "I don't want them to see me like this!" Stan had been about to say something when he cuts short and he and Kyle just look at Adam and stare open mouthed for a while. Finally, Kyle breaks the silence and asks, "I take it this is the result of one of Mario's experiments, huh?" Adam responds, "Uhh, yeah. I'm not exactly sure what to do. Mario was supposed to be right back, but he's been gone a while." "So what happened?" "I don't want to talk about it" "Wait, is that cum around your mouth? Did you suck your self off with that thing? Ha! Awesome" "Well, maybe I did, but it wasn't this big when I did! After I finished, it kinda grew out of control!" Kyle and Stan look each other and form wicked smiles "Yeah? you think it would get bigger if you ate some more of your cum?" "Uhh, I don't think that's such a good idea" Kyle and Stan moved toward Adam. Adam tried to sit up, but he was too rushed and off balance to get anywhere. Stan put his weight against Adam so he was definitely stuck of the bed. With one hand, he helper kyle massage Adam's massive dick. They spit on it in order to create better lubrication, and played with his giant balls. Soon Adam was breathing heavy and knew that all the stimulation was having the desired effect. When he knew he couldn't hold back anymore, we turned his face away and started shooting. most of it went onto the wall, but some landed on his cheek. Stan collected that portion in his hand and directed it into Adam's mouth. Kyle collected more in a cup and brought that over as well. With the two of them working together, they managed to get Adam to swallow a good amount of his cum again. Within a minute, Adam felt the tingly sensation return and his body get heavier. "Hey, the rest of you is getting slightly bigger, too. I hadn't noticed it what with your dick being so attention grabbing. Speaking of your dick, there it goes now" Adam's dick resumed the greater growth again and Adam gasped from how good it felt. Stan let go of Adams arms and Adam moved them to touch his cock. It had become incredibly think now, as big around as one of his thighs. His balls were also huge, as large as beach balls. The head of his dick extended way past the top of his normal head.
