My brother Matt is 12 years old and a nerd. He has a thin and weak body, with a face full of acne. His eyes are green and his hair is black like your dad. He's shorter than me at 5'1". Matt normally looks careless, just wearing a button-down shirt and dark-colored dress pants with black shoes. Matt spends most of his time in his room reading or playing video games. I don't have the best relationship with Matt. I like playing football and going out with my friends, going to the gym, and being active. There are entire weekends when the only time Matt comes out of his room is to eat and go to the bathroom. I just don't have anything in common with Matt, and we fight pretty often. I smirk, Matt would die of embarrassment if I ever saw him naked.
I wait until he leaves his room to go to the bathroom and sneak in quickly. I grabbed a pair of his shorts that I found on the floor and returned to my room. I stripped down, put the shorts on, and waited. Almost immediately, I felt a tingle and could tell things were changing. Not even ten seconds went by and the magical tingling sensation was gone. I was excited to see what Matt was packing between his legs. I stand in front of my full length mirror and remove the shorts.
My breath catches in my throat as I take in what I'm seeing. Matt's penis is huge. At over 7" soft it's almost bigger than mine when I'm hard. A wave of jealousy washes over me as my little brother's massive meat begins to harden finally topping out at a 11" hard and as thick as a baseball bat. I thought that this was going to be a good way to humiliate my younger brother, but now I'm the one trying to come to terms with this new information. One thing is clear, Matt can never find out that he's the biggest in the house.
