I tightly clenched the towel around me as I walked. The warm summer breeze felt like ice on my wet skin as I neared my house. Mom had called me home early from swimming at my friend Rebecca's house so I had had no time to dry off before walking. I could feel the icy drips of water bounce off my feet in my flip-flops as I neared my house. Luckily there were no neighbors out today; it was kind of embarrassing to be wearing nothing but a little blue two-piece swimsuit and a towel.
As soon as I entered the house I noticed my stepbrother Andrew passed out on the couch. He had the next few days off of work so he'd been wanting to try drinking all day for an entire Saturday, but it looks like he didn't make it past two o'clock. I laughed; he was more lightweight than I was and he was three years older. I picked up the half-empty beer bottle from his hand and took a swig.
"Shelly!" scolded my mom in the doorway.
I hid the bottle behind my back but it was too late.
She laughed as she moved towards the kitchen with an arm full of groceries. "You're lucky your birthday was last week, otherwise you'd be grounded! Plus I need help, go unload the stuff from the car!"
I took another sip of the beer and helped grab bags. I was only eighteen but I'd had way more alcohol in my life than Andrew ever had, so I thought it was kind of ironic that he was actually old enough to drink.
After everything had finished I set my towel on the couch and took a seat next to my brother, my bikini was a dry-damp that I didn't think would do too much damage to the leather. Andrew had passed out with a cooking show on tv. I laid down and rested my wet head on his lap to watch the contestants fight against each other in some lobster versus chicken cook-off in Vegas. I could hear my mom on the other side of the wall putting away the food.
"Hey Shelly," she called, "can you see if Andrew knows where he put my skillet when he washed the dishes yesterday?"
I looked up from his lap and smacked him in the face. He didn't even move. I smacked him harder.
"Hey assface," I yelled, "wake up!"
I got no reaction from him.
"He's out cold!" I called back.
"Damn," I heard her say.
I realized I had rolled my head onto his crotch when I had turned. The pressure must have excited his sleeping state because I felt the fabric hardening against my skull.
I smiled slightly. It wasn't uncomfortable, it was just funny to think that my brother had the same anatomy as other boys. I turned my head back to watch the show, letting his hardening erection press against the side of my face.
After a minute it angled up too far to be comfortable to I slid my head back to his stomach. Andrew's long dick made a bump in the fabric in front of me, obscuring my vision of the tv in one of my eyes. Instead of moving, I found myself focused on the protrusion. It was so interesting to be this close to a penis. Honestly, I'd never been this close to one. I'd had pervy guys send me dick pics growing up but I'd never found myself actually near one before.
I studied it through his shorts, wondering exactly what it looked like through the fabric. It looked big, but I couldn't tell for sure. I was almost tempted to take a peek, it would have been easy enough with his basketball shorts, but I refrained myself and stuck with just watching him grow bigger and bigger.
My mom dropped something in the kitchen.
"Dammit! Shelly, can you grab me a towel?" she called.
I got up from the couch and realized that my brother might not be horny when I got back. I took a chance and squeezed his cock through his shorts.
The size surprised me. Looking at it was one thing, but actually wrapping my fingers around it was like gripping the handle of a baseball bat. I couldn't stop myself from moving my fingers down his shaft to try and find the base.
"Shelly?" called my mom again.
Damn. I couldn't even get halfway before the fabric bunched up and stopped my hand. The only way I'd be feeling his full penis was if I pulled it out of his shorts. Which I wasn't going to do. I was only curious.
"I'll grab some mom!" I answered finally.
I grabbed a fresh towel and walked into the kitchen to see my mom's bottom half drenched in milk.
"God damn, mom," I said, "What did you do?"
"Don't worry about it," she said quickly.
I helped her clean up the mess and put the rest of the groceries away.
"I'm going to shower," mom said motioning to her soaked legs.
I laughed and went back into the living room as she went to her room. Unfortunately, Andrew's erection had subsided. I sat back on the couch and watched the final part of the episode.
As my mom's shower turned on I realized that I was now completely alone. She wouldn't be out for a while and Andrew definitely wasn't going to wake up any time soon. I got that kind of naughty feeling you get when you're totally alone in a place you weren't normally. I could do anything and no one could stop me.
I found my hand on my crotch. I had such easy access through my bikini. The thought turned me on even more: I was practically naked and touching myself next to my unconscious brother. I sucked on my fingers while touching the damp surface of my bikini bottom.
My fingers were great, but what if I could suck on a real dick? The thought was impossible, but there was an impossible situation right next to me. I could do anything to him.
I knew I wouldn't, but thinking about it turned me on even more. So I kept thinking about it, using the thought of sucking my brother off to get myself off. I wondered what a dick tasted like. Would it be anything like my fingers?
I couldn't help myself from resting my head on his crotch again. The temptation was just too strong. I lightly rubbed my face against the outline of his flaccid penis as I masturbated. I slipped my fingers into my bikini and rubbed my clit in circles. It would feel so good just to at least see a dick.
The feeling of my face must have excited his sleeping state again. His dick grew and pressed against my face as I rubbed. I bit down lightly on the top of the bulge, imagining that I was getting ready to fit the whole thing in my mouth. It continued to grow and pushed against my lips.
I couldn't take it anymore. I had to at least see it. I got on my knees in front of him and gripped the lining on his shorts; after I pulled the fabric down there would be no turning back. I briefly hesitated and then worked the front of the shorts down.
