Jake starts feeling a tingling in all four of his penises. "What, I haven't drank any more water!" he says to himself.
The skin on his penises started to merge with the meat inside. Soon four bare cocks were naked! The mushroom tip tightened so he didn't have one anymore.
By now Jake was used to seeing changes, but he didn't know what was happening now.
Very quickly his four cocks turned a pink-red color and started growing. They stopped at about ten inches long and two inches wide then started smoothing out.
Jake looked at them for a few seconds before touching one. Suddenly the penises moved around until they formed a large square and stopped. The reddish color spread until it went an inch down the inside his legs, just covered his belly-button and covered his crotch.
Jake was now lying on the grass just staring at what was once a regularly colored crotch with just one penis. He watched dumbfounded as his belly-button filled in and the red area started to grow outward. It ballooned out until it was as thick as his waist and as far as his knee taking what were his boyhoods with it!
He now recognized it as a cow's udder. Not only does it belong on a female cow, but it also belongs on an adult cow too!
He is still a boy, but his new "equipment" just make milk instead of pee now. Of coarse he does not realize that at the moment.
