Stuck at school my mind drifted back to the morning.
"We'll be back next Monday night, don't forget there's cash to get groceries, some extra for eating out, and leftovers in the fridge."
My mom said as she hugged me goodbye.
She was leaving for a week long honeymoon with my step-dad, leaving me and my step-brother to fend for ourselves at home.
It was my mom and me for a while after my dad left, we got by just the two of us until she met Mike, then she was swept off her feet, 8 months later in a whirlwind of change and here we are, she's married and I have a new brother.
Michael's 19, a year older than me, and much bigger. He was always at work, the gym, or with friends. He was never really around while our parents were dating, which isn't really saying much given how short that was, now that we live together though, it's no different.
I barely paid any attention to the class. I simply stared at the board with my head propped on my hand, thinking about after they left. Their bumper had pulled out the driveway and I had the house to myself, I saw it as the perfect opportunity to test out my new toy. A deep purple vibrator I had ordered online.
Stripping in the living room I had started with it on my clit, soon after my fingers found their way inside my pussy working me to orgasm exposed on the living room couch. In my genius as woman of the house I saw an empty home as the opportunity that it was, sliding the vibrator in-between my soaked lips on its lowest setting, I pulled my shorts back up hopped along into the kitchen, and started making some breakfast.
Then Michael walked in.
I thought he had left for work and as the vibrators low hum rang, I panicked and rushed past him out of the kitchen to my room just hoping he didn't hear it, or me from earlier. As soon as I entered my room the shock from almost being caught mixed with the vibrator still diligently going off inside of me caused my knees to buckle as I soaked my underwear and shorts.
Still in class I subconsciously slid my other hand under my desk and pressed it against my crotch, pressing my thighs around it. I was wearing a short skirt that reached halfway across my thighs, with a buttoned shirt on top. Black stockings stretched across my legs, stopping at my knees, revealing only a portion of my soft, thighs.
My fingers pressed against my panty-covered clit, and I let out a soft breath as I began to rub it. The thought of my step brother catching me flashed through my mind as I rubbed myself. Juices began to flow from my pussy, soaking my underwear, but I kept going.
Just then, the bell rang and I snapped out of my trance. Everyone began to pick up their things, while I simply sat up straight. My hand was still over my crotch as I looked around the classroom. I blinked, my eyes widening slightly as I could see a few other students glancing at me.
Gathering up my things I tossed them into my bag, got up and quickly left the classroom with everyone else.
Arriving at home, I kicked my shoes off and threw my bag to the floor. Locking the front door behind me, I shuffled into the kitchen.
Michael sat at the table looking at his phone, eating a bowl of cereal.
Walking past him I bent over, pulling open the bottom drawer next to the pantry where we keep sweets.
Unknown to me at the time, he stared at my ass as I bent over, my skirt sliding up a bit revealing just the bottom of asscheeks and underwear as I continued to search for my prize.
Sifting through the drawer I smiled as I found a small bag of chocolates. Grabbing it, I straightened up and closed the drawer.
"How was work?" I turned to him, as he quickly looked back down at his phone. I blinked, seeing his shorts tented from the middle.
"Not bad" He sighed. I nodded slowly, smiling as I held up and gestured at the bag of chocolates.
"Well... I'm heading up," I turned and started heading off to my room, "See ya."
I walked off, as he glanced back in my direction. His eyes gazing across my legs and ass as I left.
Grabbing my bag from the floor, I ran up the stairs and headed to my room. Placing my bag and the chocolates onto my desk, I closed my door. Slowly I began to unbutton my shirt as I stepped over to the closet. Opening the door, I pulled my shirt off revealing my black bra underneath. Reaching behind me, I unclipped it and pulled it off, setting my chest free.
I heard the front door open from my room, and some muffled voices entering the house, must be Michaels friends. We're only a year apart and Michael used to go to my school. Though he graduated last year, I do know some of his friends that are in my grade, or doing a leap year.
I returned to undressing, paying them no more mind. Pulling my skirt and underwear off together I grabbed a pair of pink shorts to replace them. I slid them on. I liked these shorts they were really light and comfortable for wearing around the house. Only downside was they exposed most of my thighs and would frequently ride up on me. I had taken to wearing them without underwear because every so often they would rub against my pussy as they rode up. It was a habit that I should probably change if im honest with myself. Before now it was just mom and me and she was barely home. Even now her and my step-dad are gone most the time, and even Michaels barely around, but he is still here some days, so to wear them is probably risking exposing myself. That thought though, is what drives me to wear them.
