My little sister was stealing money out of mom's purse. I had suspected it for a while, but until now I never had any proof. Mom had always been a little absent minded. But lately, at the rate she'd been misplacing a $20 here and $10 there, well I think even she knew the truth. One of her kids was ripping her off. She just couldn't bring herself to actually say it. I knew it wasn't me, so that didn't leave a whole lot of other suspects.

I'd been sneaking around trying to catch sis for a few days. I'll admit, she was pretty damn good at evasion. But I'd finally caught her red handed and had the proof on my phone. A fifteen second long video of her rummaging through our mother's massive purse, fishing out the wallet and then plucking a crisp new twenty out of the small wad of cash inside, before tucking it all back in place and slipping the money in her hip pocket.

That night after mom went to work and we were alone at home, I left a note stuck to the fridge with a magnet. I knew she'd read it sooner or later. She always got the munchies around midnight and needed cookies or ice cream. I just kicked back and waited...

About half past twelve she pushed my bedroom door open and glared at me. "So what's the note supposed to mean?? Some stupid little red hand and "come see me" scribbled at the bottom."
I smiled and held up my phone.
"It means I caught you red handed," I said. "Stealing money from mom's purse. I knew it was you."
I'll give sis credit she had a great poker face.
"Oh fuck you," she replied. "You didn't catch me doing shit."
"Well now, this video says different," I sighed and played it for her.
"Damn snoop," she muttered under her breath. "So that's why you've been shadowing me. I knew you were up to something."
"Oh, that's not all," I said, slipping my phone back into my pocket. "Have you checked your stash lately??'
"My what??" Her poker face finally showed some cracks.
I opened a drawer and pulled out a sandwich bag full of pot. She snatched it out of my hands, furious.
"Bastard! So you've been going through my room too??"
"Oh save the outrage," I replied. "For someone that rips off her own mother on a regular basis I think thou protesteth a little bit much, eh??"
She started to leave the room.
"I don't remember saying you could leave."
"Fuck you," she snapped, but stopped.
"I recorded finding the pot in your room too," I said. "So I've pretty well got you by the pubes."
She was red now, hands on her hips, face screwed up in anger. "Now what??"
I rolled off my bed and sat on the edge. "Now what. Hmm... blackmail I think."
"You really are a bastard, you know that??"
"Last time I checked mom wasn't married to your dad either when you were born so yeah," I replied. "Takes one to know one."
"What do you want??" She asked.
"Well," I smiled pleasantly and folded my arms across my chest. "Naked pictures of your friend Maegen for starters."
"How in the hell am I supposed to get those??"
"Be creative," I dropped the smile and stretched back out on my bed. "You're on a time limit. You've got five days."

Four nights later I was opening an e-mail with several attachments. Good ol' sis, I smiled. There was her best friend Maegen in all her bare assed charm. Tall, leggy brown eyed Maegen with possibly the world's greatest set of tits. Not a bad little ass either.
"I don't need to know how you pulled that off," I said, sticking my head into my sister's room later that same night. "But congratulations. Well done."
"I did what you asked," she said. "Delete the videos."
"Oh noooo," I laughed. "We're not even close to being finished. I want more out of you than a few naked pics of Maegen."
She shook her head, no longer staring at me.
"What now," she finally breathed.
"What now, see I love that question," I told her. "You should ask that after you complete the next task too."
She barked a short laugh, it wasn't the least bit humorous. "the next task ...."
"You know it's been a while since I've had a steady girlfriend," I said. "Almost a year."
"I can't imagine why," she replied sarcastically.
"Being that I'm a healthy young man in the prime of my life, and being that I'm just full of strong hetero urges," I cracked my knuckles. "I think I'd like a blowjob."
She stared at me.
"You're out of your fucking mind!"
"Maybe," I shrugged. "But I still want one and since you happen to be the only female here, I guess that means..."
"It means you can go to hell," she stormed over to the door and slammed it in my face.
I stood there a moment. "Is that a no??"
Then, grinning I walked back to my room. Knowing full well she'd change her mind eventually.
It was two hours later and I'd started to think, wow she really means to hold out and let me show mom the videos when she came to my room.
"I hate you," she muttered.
"Yeah you've been telling me that since we were in diapers practically," I stood up and unzipped my jeans, working my flaccid cock out.
Sis was no Maegen, but she wasn't bad. She was fifteen, jet black hair cut short, big blue eyes, short, slender, small perky tits, cute little round butt. She started to get down on her knees. I stopped her.
"You know what, I really like that yellow bikini you wore last summer when we went to the beach," I said. "I want you to put that on and do it."
She didn't argue this time, just did it. She came back in after changing and got on her knees, taking my cock in one hand and stroking it until it hardened. She then proceeded to give me a world class blowjob. She didn't even flinch when I blew my load in her mouth.
"Something tells me you've done that before," I sighed, lying back on my bed afterward and relaxing.
She didn't say a word just left the room.

I guess I could have stopped with that. I mean, I'd busted her doing 2 things she shouldn't have been doing and now she'd done me 2 favors. But I couldn't resist asking for one more thing.
"Ok, this is the last thing I swear," I told her one night. "Do this and I'll let you delete the videos personally."
"What? ?" She asked.
"I want to fuck Maegen," I said.
"Oh please," she rolled her eyes. "Getting pictures is one thing, getting her to do that is another!"
"I never said it would be easy," I told her.
"Try impossible," she replied. "Try never happening. Maegen is a lesbian. I had to convince her I liked her and make out with her to get those pictures."
"Whoa, wait what," I held up my hands. "Go back, you did what now??"
"Maegen's always had a crush on me," she said. "But I like guys. Well, mostly anyway... I lied to her and told her I'd been thinking about it and I wanted to experiment with a girl. So we made out and then I asked for nudie pics. At first she was all, why you can see me anytime. But I finally badgered her into it."
"No shit," I laughed. "So my little sis went all bush pilot to get me those pics."
"More like little sis scored with the girl you dream of," she shot back. "Hows it feel to know I can have Maegen anytime I feel like it while you never can??"
"Sounds about like how my life goes," I shrugged. "But its whatever. I guess I have to ask for something else."
"Oh shit .... what??"
"I want to fuck you then," I said.
"No way," she said. "A blowjob is one thing, this... no. Go ahead show mom the videos. I don't give a damn."
"K then," I said and walked away.
She came to my room early the next morning before mom got home from work.
"I'll talk to Maegen," she said and went away.

"I just want you to know I think you're a fucking scumbag for blackmailing your own sister," Maegen told me a few days later. She had agreed to a sleepover with sis, a little cover for agreeing to do what sis had somehow talked her into doing. "If I didn't love her this wouldn't be happening. As a matter of fact I might just have a couple guys I know kick your ass for this."
"Ok," I replied, not caring a bit. "So you want to be on top or bottom??"
Maegen just gaped at me "Unbe fucking leavable. Is he for real??"
"He's retarded," my sister said. "Look at his room. I mean how old is he and look at this shit. Star Trek toys, comic books, action figures."
"Hey, those are collectibles," I said. "They're an investment."
Both girls rolled there eyes.
My sister left the room and Maegen undressed, so did I. I tried to kiss her, she shoved me aside. "No kissing. Just do what you asked to do and get it over with."
"But if I don't get a kiss I won't feel loved," I made a pouty face.
"I totally understand why she wants you dead," Maegen told me.
She lie down on my bed and I put on a condom and climbed on top. I imagine the sex would have been a lot better if she'd actually moved and not just lie there like a corpse. I finished up and got dressed.
"Well that wasn't as amazing as I thought," I smirked.
"Good," she picked her clothes up and left the room.

A minute later my sister walked in smiling from ear to ear.
"I wonder how long you'll get for raping Maegen," she said. "Poor kid comes over to spend some time with me and my brother forces himself on her. Jeez... a few years at least."
"Huh??" I blinked.
Maegen joined her, smiling. "Blackmail time. Let's start off by you giving us that phone...."
"We can talk about this right," I asked. "Right.... girls??"
