I couldn't believe it, peeking through the crack in the bathroom door at my little brother Todd's enormous penis. It was the biggest dick I had ever seen and it was my kid brothers. He was furiously stroking it, had been for about five minutes while I watched. I felt my body arouse, felt my nipples press out behind my bra and my sex tingle as my insides moistened. I couldn't look away as he manipulated the long wide shaft with no lubrication, just moving the loose skin up and down his vein ribbed monster.
I waited with baited breath for the climax, knowing he had to be close from the look of his cock and balls. Not to mention the expression on his face and how his legs tightened, lifting his butt in his jeans. His cock was poking out of his zipper along with his balls, with the fly undone completely and his belt dangling and moving in the air as his hand stroked up and down the impressive tool. He had to be eight maybe nine inches, I couldn't be sure.
Suddenly he leaned forward, went up on his toes and exploded onto the countertop, next to the sink. His cum shot to the mirror and would have gone further if it wouldn't have been there. The first rope left a trail from the glass to his convulsing cock, running down the reflective surface to the counter just as another, even bigger, burst flew from his slit. I heard him grunt, stroke hard again, sending another rope out of his shaft. I was awestruck with his power and potency, never seeing that much cum before in my life. I swear a good seven long blasts painted the bathroom counter and a large puddle formed under his head by the time he was done.
My mouth watered, my sex quivered and dripped. His dick ceased its orgasmic show, and he let it loose to gather toilet paper in a wad to clean up the yummy mess he had made. All that glorious cum going to waste down the toilet, made me jealous and sad. I imagined him shooting that huge load in my mouth, how it would fill me to overflowing before I swallowed it down. In my musing I almost got caught watching because he was done cleaning up and about to exit. If it wasn't for him flushing the toilet I would have been. I darted away down the hall to my room and shut the door behind me, horny as hell.
I call him my little brother even though we are the same age. I was born two minutes before him. We're twins, both turned eighteen last Friday. This was the first time I had caught him tossing off. I knew he did it; sometimes he doesn't clean up very well, leaving streaks on the mirror and counter in the bathroom. I lucked out this time and found the door cracked. Probably because he thought he was home alone. He thought wrong and I got the show of a lifetime.
I couldn't get his cock out of my mind, falling on my bed with my hands already down my pants. I was very wet and my clitoris was erect, begging to be played with. I rolled over on my tummy and began to grind on my clit with both hands, rolling my nubbin between my fingers, slipping up and down in my juices. The pleasure grew quickly, my breathing became rushed as my arms pressed my breasts together, smashed on the bed. The euphoria spread through my body the more I played and tightened my ass, grinding harder on my clit until the wave crashed over my body, drowning me in bliss.
I was so wet after my orgasm I needed to change my panties. I stood up, my legs wobbly and took off my shorts, pulled my panties down, letting the cool air find my wet pussy and excited clit. It felt good, sending shivers through my body and hardening my nipples again. I thought about how good my brother's cock would feel deep inside of me. I'd never had anything near his size and I know they say size doesn't matter but I couldn't stop thinking about putting that to the test. I found myself playing again, half naked in my room with two fingers in my wet tunnel when a knock on my door scared the shit out of me.
"Don't come in! I'm not..." I started to say but the door opened anyway.
I turned, covering up, and in poked Todd's head as he removed his headphones to talk.
"Todd! Get out!" I screamed.
"Sorry! My bad!" she said, shutting the door very fast.
He must not have heard me say not to come it and there I was half naked covering my wet pussy with my hands. It was wet because of my thoughts about him and he just walked in on me fingering myself. Well I guess we were sort of even except I got a much longer show. It was going to be weird now to see him and talk to him, but I couldn't give away what I saw and did.
I cleaned myself up as best I could, got some new underwear and put my shorts back on. It was July our first summer after graduation before we left for different schools in the fall and would be away from each other for the first time in our lives. It was going to be strange not to have him around. We were good buds, usually talking about everything together and doing things as well. He was probably coming to talk now about something.
I headed to find him, searching the house. He was downstairs, playing pool and when he saw me he turned red.
"Hey, what did you want?" I asked.
"Oh, well just wanted to talk to you.... I'm really sorry about walking in on you. I had my headphones on."
"Yeah, I figured, no big deal, I don't think you saw much, right?"
"Right," he grinned slightly.
"So what did you want to talk about?" I asked, picking up a stick and hitting a shot.
"Sara."
Sara was Todd's girlfriend; I didn't like her much, probably because he was always complaining about her to me.
"Oh great, what now?" I asked.
"I'm going nuts... she said she'd change but she hasn't."
"So she lied, she's not having more sex with you?"
"No... none... it's like she doesn't like it."
Well that explains why my little Bro was tossing off so much. Frigid Sara wasn't giving it up. What a stupid bitch, how can she not want Todd's cock all the time?
"That sucks, Todd... I'd dump her if I was you.. sure she's hot but if she's not putting out what's the point?"
"Exactly... I knew you would understand. I think I'm going to have to. I should be getting a lot more at my age and I'm not."
"Yes you should." I said without thinking.
He looked at me weird but then smiled and hit a shot. I was mad, mad at Sara and really wanting to make things better for my brother. I almost convinced myself that I would be doing him a favor. I thought about suggesting I help him out when he needs some release but I didn't know what he would think about that so I kept my mouth shut. I thought about stroking him off, maybe even sucking him to empty his large balls and curbing his urges. I was so into the thought that I didn't hear him tell me it was my turn to shoot pool until he shouted my name again.
"Julie! Julie... your shot!"
"Sorry, I was thinking about something."
"I'll say... you were totally zoned out. What was so important?"
"I'm just mad at Sara, I don't get why she doesn't want to have sex. Did she give you any excuses?"
"Yeah, but I'd rather not say... you'll think I'm lying."
"No I won't... tell me."
"Okay, but I'm being serious, Julie, this isn't me making shit up."
"Fine. Tell me."
"Sara said.... Well, she said I hurt her... she said I was too big and it hurt."
I knew it was no lie, especially after what I saw today. A surge of lust overcame me; I took a deep breath, gathering myself.
"I see... well, you must be pretty big then. How big are you?"
"What? Did you just ask me how big my dick is?"
"I guess I did... is that weird... I mean you brought it up."
"Sort of I guess... well I've never really measured it but it's about this long and thicker then the end of this cue," he said showing me how long on the stick and he wasn't exaggerating.
"Wow, are you serious? I don't know if I believe that, Todd."
"I told you I was telling the truth and I'll prove it if I have to."
"Oh really, you're going to whip it out right here are ya, Sport."
"If I have to."
I so wanted him to. Right here in the basement, I wanted my brother to take his cock out and show me just how big he really was.
"Well, if you are as big as you say you are I can see why Sara had problems. She's a tiny little thing but even she can get used to it in time. It sounds like she doesn't want to try very hard. If you are that big," I teased.
"That's it. I'm showing you and you'll have to deal with it," he said putting his cue down and unbuckling his pants.
My heart skipped a beat and began to race. I couldn't turn away or say anything.
"Just don't tell Mom or Dad I did this."
I nodded as his pants hit the carpet. He hesitated looking at me before pulling his jockey shorts down over his semi hard cock. I gasp for effect, but really wasn't surprised to see the long wide shaft falling between his legs and hovering in the air. He looked so good I fought the urge to bite my lip.
"Told you," he said after my gasp. "It gets bigger when it's erect."
"Wow... Wow... that is big. I... don't know what to say."
He pulled his jockey's back up, covering his yummy cock to my disappointment.
"You know there is other ways to help you out. You don't have to screw Sara all the time. She could use her hand or even suck you."
"Yeah, I suggested that but she says it hurts her mouth and she doesn't like to get slimy and gross when she touches it."
"Oh for fuck sakes!" I blurted, beside myself. "Dump her... you have to or I'll kill her the next time I see her!"
"Wooh, settle down, Sis... why so angry?"
"It just gets my goat when I hear shit like that."
"I see... so you don't have a problem getting slimy or sucking dicks?"
"If you must know... No I don't. I like it... a lot and it pisses me off when women complain about it."
"Must run in the family," he smiled.
"Why, because you like it when someone does it? Or you suck cock?" I teased.
