Author's Note: This is the requested sequel to Perving Off Together. Rarely has one of my shorts had so many requests for a sequel. So quickly too! Hope you all enjoy it! And thank you all for reading!
I came home from work and stopped to listen. But there were no sounds and I sighed, then went to the kitchen to get a soda. My name is Dennis, and I'm a total perv.
So is my sister.
Our stepmother Alice, who married our dad a few years back, is a chronic masturbation fiend whenever my dad isn't around. Which is often since my dad travels a lot for business. So she retreats to self-pleasure when he's not around.
At least she doesn't cheat on him right?
I learned about her masturbation habit by coming home early one day and hearing her playing with herself while watching porn on her phone. I'd found this out and it had turned me on so bad I wound up jerking off to her.
Like I said, I'm a perv.
I'd done this a few times, always so hot to do so. Then my sister Lila had gotten involved when, after fighting with my stepmother over her grades, Lila had heard how I'd found out about Alice's habit. She'd dared me to prove it.
Which I'd done.
And we'd both perv'd on my stepmother over it. Masturbated together watching Alice masturbate. It'd been almost hotter than the spying itself and we'd had a little agreement to do it again. Which we'd done twice more. The second time we'd done it she'd jerked me off and I'd stuck my fingers in her, which had made us both cum even harder. We'd almost gotten caught that time as Lila's moans in particular got a bit loud. But Alice had not decided to look for us.
After almost being caught, Lila and I had mutually agreed to not perv on her for a while. My dad had come back after that, so our spying chances were limited. But he was off on another trip now.
Alice walked into the kitchen at that moment, her big tits looking like they were about to bust out of her tank top. "Light work day?" she asked me.
"Yes," I replied. "Lila home?"
"No," Alice's face fell. Alice and Lila still bickered regularly over Lila's grades, which had no improved much since the last argument.
I shrugged and went to my room. I picked up my controller and began laying video games again. I heard the door slam about an hour later and then voices rose. I shook my head. I was not going downstairs to get in the middle of that shit again. Eventually I heard Lila's voice saying "fuck you!" before stomping up the stairs. How my skinny little sister makes so much noise climbing the stairs, I'll never know. Nor do I care to find out. I went on playing my game and ignored the rest of the house until, about a half hour later, my door was knocked open.
"You are home!" said my tiny little sister. She was 5'3, skinny, with her brown hair currently all messed up.
"Yes," I said.
"Did you hear what she said to me?"
"To be honest Lila, you two fight so much I don't care to listen anymore."
"She took my credit card after stooging off to dad that I fucked up on my last English test!" snapped Lila. I shrugged. "Fucking bitch," said Lila, irritable at my non-response.
"If you came here just to bitch about that, go find one of your friends on Instagram or whatever," I said. "I'm trying to game here."
She glared at me, but then sat down in my spare chair. She watched me play GTA for a little while, then spoke in a calmer voice. "I'm sorry, I'm just pissed at her. And pent up."
I paused the game. "Pent up?"
"Haven't cum in a week," she explained.
"Same," I replied.
"Dad's gone," she said. "Want to perv on the bitch tomorrow?"
"It's remarkable how quick you go from cursing her to wanting to cum to her," I said. She flipped me off but didn't deny it. "Sure Lila, I'll do it with you. If we do each other again, you need to keep your voice down!"
She laughed. "I'll try."
The next day we followed what had become our standard pattern. We came into the house at the hour of the day where we knew Alice thought she was alone. We crept into the house quietly, listening for the telltale sounds of woman loudly masturbating. Upon hearing it, we crept up the stairs to her and our dad's room. As usual, she left the door ajar and we could see everything.
Alice was wearing her silk robe, which was wide open showing us everything. Her phone was beside her and she was watching porn and already playing with herself. Fuck it was such a hot sight.
Lila took one look at it and pulled her shirt to show her small tits, then plunged her own hand into her shorts. That made me even hotter and I whipped my hard dick out, stroking effortlessly. Lila had mashed her lips together as she hotly rubbed her little pussy. "Oh yes," Alice said as she pushed two fingers into her own pussy. I stroked my cock, watching her, then watching Lila.
I mouthed at Lila 'want my hand?'
Lila stepped forward and took my dick in her small hand. I reached down and rubbed her soaked little slit exactly as I'd seen her do it. Lila's moans were barely being kept in. She really was pent up. Finally a small moan escaped her.
Alice stopped and looked up.
Fuck! Lila had been too loud! I pulled my fingers back from her but we both held still. If she heard us frantically running away, she'd know for sure someone was watching. I held my breath and so did Lila. Finally Alice laid back down, shaking her head. "I'm so horny I'm hearing shit," she said aloud, returning her hand to her pussy.
I looked at Lila and whispered "you almost got us caught again!"
"I'm sorry!" she whispered back.
"If you can't keep your mouth shut, I will!" I promised.
"How?"
In response I quickly pushed her onto her knees and stuffed my dick into her mouth before she could protest. She looked up at me with angry eyes for a few moments but I shook my head, holding in my own moans as her warm mouth enveloped my dick. "Suck me, slut," I commanded via a whisper.
Lila looked mad still but then her own hormones took over and she started doing exactly that. Her pretty little head bobbed back and forth on my hardness while I watched Alice masturbate more. Lila was good at sucking cock. Little ho must have had practice at school. I clenched my teeth hard as it felt better and better. "Fuck!" I finally whispered as I shot a load into her mouth. She looked surprised and pulled off my dick, glaring at me.
