Hi, my name is Zack, I was born on the year 2000, currently, it's 2014. I'm white, average height, on the skinny side, lack of hair except on the head, and I have black hair. I'm considered smarter than average in my class, except for my dick, it's huge for my age, its 6.8 inches when erect, it's crazy. I have 2 brothers, one of them is currently 18, and the other is my younger brother of 10 years old.
A couple years back, around 2012, when I was 12 years old, I gained 2 powers, I don't know how, but I woke up one morning, after being startled awake. My brother had ran in, and tossed my blankets, and stared right at my body, where I was completely naked (I have always enjoyed sleeping in the nude,) and worst of all, I had an increasingly common rock hard erection from an unfinished wet dream. I remember staring at him in fear, then he left, as he left the room, I hear him yelling to my mother
"He must have left the house already!"
I was so confused that I quickly got up, grabbed a random pair of underwear, paying no attention to what I grabbed, and started putting them on in front of the mirror. I noticed 2 things the moment I looked in the mirror. The first thing was that I wasn't viewable in the mirror, invisible, and the second, was that I was actually putting on a male, mostly see-through, G-string. My cheeks went red as I realized what I picked up, I forgot that dad had one of these, and that we had done our underwear in one single load last night. However, I was too lazy to go back for another pair, so I put them on, and got an erection. I didn't know it at the time, but I had an underwear fetish, and a crush on my brother and father. I take out my dick, keeping the underwear on, and start jerking myself off. Suddenly, my mother comes in my room saying my name, and I froze, and tightened my eyes, and hoped she couldn't see me or the underwear with all my heart, she walked away shortly after seemingly saying to herself quietly
"I thought I hear him in here, weird."
I opened my eyes after, and for a moment, I couldn't see the underwear, but it came back into view 1 second after. I found out later that if I concentrate hard enough, the clothes I wear will be invisible as well.
After what had happened, I take off the underwear, putting it back where I found it, and I quietly go outside and into the forest at the back of the house. I also later found out that while invisible no bugs will be able to land on me for unknown reasons, and they won't be able smell or feel me. So after I go to a small abandoned building (about 10 feet wide, and 20 feet long, with a very short wall outline of bricks for cover,) that I had heard couple go to often to have fun, I get a little naughty, and hope someone comes around to see me naked with an erection. Lo and behold, I see 2 guys moving my direction, kissing and playing with each other's crotch. They stop for a moment to get situated, but see me with my hand on my dick, staring at them. As they start to yell for me, I bolt away, and when I get to an area with too many trees to see me, I wished I wasn't seen and regretted coming out. They found the area I was at and stared right at me, but like my brother the morning of, they didn't see me. That was how I found out that just thinking to be seen, or not to be seen, can affect my invisibility, with as much ease as possible as well! They turn around and start running back to the abandoned building.
I eventually make it back to the building, and they have already stripped their clothes, with their cocks out. They both seemed pretty young, contrary to my first view of them, with little hair to be seen on either of them. The guy sitting down on an arranged pile of bricks had blond hair, skinny, but toned body, blue eyes, and seemed to be a foot taller than me. His erect dick was HUGE, it looked to be 7 and 1/2 inches, or closer to 8 inches long. The other guy, bending down and getting ready to suck the other guy's dick, had brown hair, he was skinny, but not toned, and had brown eyes. He had a dick size that looked to be about 7 or less. I finally noticed what kind of underwear the blond guy was wearing after he started to completely take off his underwear. It was just an extremely small pouch with a super thin string going around the waist, it didn't even have 2 strings to tie together, just 1 whole string! (I later found out this was called a banana hammock. I started jerking off after the blond guy took off his underwear, and I noticed him stuff it in his cargo shorts. I quietly got closer and tried to grab the underwear from inside. And the craziest thing happened! My hand went through the shorts! As this happened, the blond guy moved the brown haired guy, and started roughly fucking him, like fucking him really faster while going almost in and out of his ass. I tried to grab the underwear, but it wouldn't let me! I moved my hand away, tried the grab the shorts, and I couldn't, my hand kept phasing through. Then I tried grabbing it, with the intent on touching it, and I could. This startled the guys, at the sudden weird movement of the shorts, but they yelped, which startled me. This caused me to fall down as the brown haired guy went down on the blond haired guy. I landed on the guy's dick, causing him to yelp and squeeze his ass tighter, which caused the blond haired guy to cum, causing the brown haired guy to cum. Because I've been jerking off and on, with no clothes at all to spare, in public, and watching 2 guys fuck, and being cummed inside of, I came as well, but not that much. Interestingly, I could see my own cum, indicating that what came out of my body wouldn't be invisible. I struggled up, and I hear them talking to each other about what just happened, neither of them knowing of course. They eat the cum that leaked out of the brown haired guys ass, and my cum that hit the wall. They taste my cum, and have weird looks, indicating they know the taste of their own cum, and that wasn't theirs.
I quickly rush back home, quietly go inside, go and grab the underwear I tossed aside earlier, put them on, then put on boxers that are way too big for me, then quietly walked back outside, then somewhat loudly walk inside, and I hear my mom yell
"welcome back!"
My dad shows up, sees me in my boxers, and `nothing' else, and asks "where have you been in that attire?"
I responded with "Jogging around the forest, it was fairly cool today, so I'd thought I'd enjoy the cool air to the maximum I could, before it warmed up."
My dad walks up to me, laughs, pats me on the head twice, then walks to the living room. I go to my room and test out my new powers, making sure I understand them before tomorrow, a school day, begins.
