Eric looks at the shake and decides its worth a shot "Nothing to lose, everything to gain" he says, trying to boost his confidence. He drinks the shake and then sits on the couch to watch some tv. As time goes on he keeps having to readjust as he just cant get his bulge to sit right. He looks down and sees his crotch looks like its pushing out a little further. He takes off his underwear and looks down at his dick as it looks like its getting bigger. He thinks that he got scammed and the "protein power" was just some some drug to get him hard. But as he looks closer, he realizes that he isnt getting hard, his dick is getting longer and thicker but staying soft. "I have the be hallucinating right? There's no way this is real?" he panickily states. He reaches down and starts playing with his newly developed member as it feels so sensitive to his touch and starts getting hard. He goes to grab a measuring tape as his cock continues to grow. he starts to jerk it to full size before taking a measurement and finding out that his cock has grown from a measly 4 inches while hard to a powerful 11.5 inches. He starts to jerk his shaft when suddenly he feels something hitting him each time and sees his balls have started to grow. Each jerk fills them more and more until theyre the size of softballs hanging off his body. He massages his balls with one hand and jerks his giant cock with the other his cock erupts covering him in his own warm sticky cum.
