My name is Greg. I'm 25 and my younger half brother is Dan. He's 19. We got an apartment together near Dan's school. He had a decent income from his trust fund that his dad set up, and I worked at a decent paying job. It worked for a lot of reasons, mostly because Dan wanted to party without our mom around, and I wanted to be independent.
We started off great. I went to work Dan did his homework and went to class, then Friday nights he would have a party. Dan wasn't really any better looking than me. We were both about 6 foot tall, he had blue eyes to my green. He had black hair to my blonde hair. He had a lean swimmers build while I was more broad of shoulder and stout of chest. But neither of us were out of shape or terrible to look upon. But Dan had one thing i didn't have. He was incredibly confident.
I don't know if my lack of confidence was from having a step dad at a young age, not being particularly great at sports or school, or... more likely because of my diminutive dick. I hadn't seen Dan's since we were kids, but mine hasn't grown much since we were young. I have 4 inches when it's hard and it's about the same in girth. When I'm soft though, it looks like an acorn with two pea sized balls. I shave myself completely bare, but that's more because I like the feel of it than anything.
I mostly watched porn, my specific favorite had been cuckold porn. Something about a guy with inadequate sex organs marrying a hot girl who later made him accept his inadequacy, just turned me on. It probably didn't hurt either that I had been with 2 girls. One was a pity fuck and the other a steady girlfriend, her name was Emily. The pity fuck was pitiable as I came from going down on her. The girlfriend was pathetic too, I never actually lasted long enough to make her moan with my dick. But I did get goof at following orders on where to lick.
Dan as far as I knew had tons of girls. He'd have new ones come over to our parents house all the time, or conversely he'd stay out all night and come home smelling of perfume.
On our first Friday as roomies Dan was having a party. He invited a lot of beautiful girls over. I tried to sneak off into my room but when I opened the door there were two girls making out on my bed. One was a girl I had been crushing on for a while. Her name was Michelle. She was about 5'4" with curly red hair, blue eyes, perfect C cup boobs, and a great big toned bubble butt. I had seen her at the beach once in a thong bikini and almost came in my shorts from her sun bathing. It was beautiful.
The girl she was kissing was pretty as well I had just met her the other day, her name was Sierra. She was shorter than Michelle, maybe by and inch or 2. But where Michelle had tits that fit her body type Sierra had enormous melons easily DD's maybe bigger. Her butt wasn't as big and juicy as Michelle's, but it was still pretty nice if her booty shorts were anything to go by. Michelle has pale white flesh kissed with a few freckles, while Sierra had more of an olive skin complexion.
I didn't know what to do at first, so I stood there and watched them kiss and grope each other. I felt a rise in my pants, it felt urgent. Not like a normal hard on, but the kind that consumed your mind completely. I closed the door quietly behind me.
I don't know if I thought I was going to get a threesome or if it was a voyeuristic compulsion. But I side stepped away from the door as quietly as possible and got myself in a good position to watch. I wasn't hiding, but I also wasn't announcing my presence. Michelle slowly removed Sierra's top and her bra. "Oh my god these things are beautiful, and your nipples are so cute and tiny" she said as she started to suck on Sierra's small dark walnut sized areolas.
Sierra moaned and grabbed Michelle's ass. She squeezed it and smacked it. Michelle's jeans did nothing to hide the ripple effect and I felt my dick twitch again, the tent in my pants was small to be sure, but I definitely noticed the tightness of my pants right then. Precum started to collect in the front of my boxers, but they still hadn't noticed me. Or at least didn't say anything.
Sierra took off Michelle's top and showed her puffy pink nipples, they were almost as erect as Sierra's. She started to circle her tongue around them and slowly unbuttoned her pants and tried to maneuver them around her big perfect ass. Once they were all the way down and Michelle was in nothing but her lacey pink thong, my dick spasmed. I didn't cum, but I was definitely getting close. Sierra got behind Michelle and kissed her perfect cheek and slapped it. Both Michelle and I moaned at the same time.
They both stopped and looked at me. "Are you Dan's brother?" They asked, not shocked more an honest inquiry than anything.
"Yeah, I'm Greg, the older brother" I said like an idiot.
"You're a lot different than you're brother aren't you?" Sierra asked still on her knees admiring Michelle's work of art.
"Umm yeah... I guess so. Why do you say that?"
"Because he would have pulled down his pants and joined us by now, but you're over there cumming in your pants" Michelle said laughing a little. I stood there trying to think if this was an invitation or if they were simply amused at my timidity compared to my brother.
Sierra slid Michelle's thong down her legs and kissed both cheeks before throwing her back on the bed facing me. Her legs were open and I saw it. She had a perfectly shaven mound leading down to a moist pink pussy that was begging for some big cock. Sierra instead met her with 3 fingers and a tongue and went to work. Michelle moaned louder than before and then looked me in the eyes.
She didn't say anything but I knew this was a test. I hoped that she was so horny that my size didn't matter. I even reasoned that I was probably bigger now than I realized because of how turned on I was. I dropped my pants and boxers releasing my dick from its denim prison and showing the girls (albeit just Michelle right at this moment) what I had to offer.
She choked on her laugh which caused Sierra to stop what she was doing and look behind her to see my fully erect 4 inch snake leaking precum like a busted hose drips water.
Sierra looked back, confused at first then she began to show a wicked grin. I looked down to see what they were seeing. My dick like it always did when I was horny. It was it's full 4 inches with my circumcised head dripping precum. My balls were fully retracted into my body signaling how close I was already to cumming, but as she held out her pinky toward me I bucked my hips forward. I was begging for this humiliation.
I wanted to partake in this sexy pairing of curves and shaved mounds, but even more than that I wanted them to give me unfiltered opinions on my shrimpy boy dick.
