"Hey Riley, I'm going to go take a shower, do you want to too?" Nick asked.
"Sure, why not."Riley accepted.
The two boys walked back to their room thinking of how they would feel afterwards. As they walked their clothes felt quite snug, in fact their abs was showing of some nice six packs, however they were to drunk to realize. When they got back to their room they found a new set of clothes and a bath robe. Grabbing a bath robe and a towel from the closet they both walked into the bathroom. The saw that there was one stall with two shower heads on it, as if they were suspected to take a shower together.
Both boys undressed with difficulties and turned on the water to a nice warm temperature. As both walked under their shower heads they moaned.
"WOW, I've never made that deep of a sound before!" Nick said in voice that was an octave lower than normal.
"Holy Sh*t, was that you!" Riley shouted in an also deep, surprised voice. " And my voice is deeper too."
"Look at your penis! It's huge." Nick said in awe.
"Your's is large as well." Riley informed.
At that moment their testosterone kicked into high gear, and their balls dropped.
"Sh*t, is it me or is the water spaying lower! Riley said with his voice cracking violently.
"I think we're getting taller." Nick answered with his voice starting to do the same thing.
"Man, I feel as if my balls are going to explode." Riley complained.
"No kidding, here try moving your hand up and down your penis it feels good. Nick instructed. Within moments both boys were at their climax and sprayed each other with testosterone infused cum, which slowly sank into their skin.
