Happy Birdday Page 13 (Patreon)

Erik tries the hyper muscle potion and gets a few growth spurts. Just when he thinks it's done, there's more!

Also it was really tempting to give him a hyper dick as well. But I'm trying to control myself and keep the growtions only to what they're supposed to effect. (I wasn't entirely successful with Hank... >_> ) This has the humorous side effect of making Erik's dick look kind of small in comparison to the rest of his hyper muscled body. Although it's still the same size in comparison to everyone else. I ended up liking that consequence after I thought about it some, so I'm kind of glad I ended up doing it this way.

I have one more page after this where they decide to buy the hyper growtion, then it's on to the actual party that this comic was supposed to be about in the first place!
