This is a work of fiction. All characters are over eighteen years of age.
"Hey sis, c'mere for a sec!" I called. My sister Amber was heading down the hall, she stopped and gave me the Death Glare. I remained calm. Amber's fierce but tiny, for a twenty year old you think she'd be taller than 5'2".
"What, dork?" Amber was more of a punk type but really her own style. She was the rebellious one, I was the calm science-nerd type. But as I'm a foot taller than her in addition to being a year older, she didn't scare me. Not too much anyway.
"Wanna show you something, come in and close the door." Amber's eyebrows went up but she did it. I went to my desk, there were three quarters on it in a triangle pattern. I looked at Amber, clasped my hands behind my back and closed my eyes.
The coins rose and hovered an inch or two over the surface of the desk. They shifted positions so the triangle pointed first up, then down, then right and left. Then they settled back down on the desk. All this happened without a sound.
I could tell Amber was impressed but trying not to show it. "Magnets?" was her only comment. I'd been watching her through mostly-closed lids to see her reaction.
"Nope," I said, and tapped my skull. "All me. I've been practicing for a couple years, getting better at it, whatever
it
is." I paused for effect. "No one else knows about this, knows I can do this stuff. I'd like it if you could keep it a secret."
She thought about it for a second, said "Yeah, I get it. Who wants extra hassle? So is this all you can do? Can you like, read minds or anything?" She seemed vaguely interested, which for her meant she thought it was the shit.
"Well," I said, "I can control three small areas at once, from what I can determine, and I can subtly affect matter in those areas. Make things lighter or heavier, warmer or colder too. Not very much weight, that can tire me out, but enough." I chuckled. "No mind reading, sorry."
"I gotta say bro, pretty cool! And keeping it a secret, from
me
, that's impressive too." She gave me her Wicked Smile, I knew how right she was about that. Amber's a first class snoop.
"Wait, there's more," I said. "Why don't you sit on the bed, I'll show you?" She bounced down on the mattress, looked up at me. I didn't want her standing up for this. It was something I'd tried on myself many times, I knew what could happen.
All at once Amber's eyes grew huge and round and her mouth dropped into an O of surprise and pleasure. She flopped back on the mattress, her hands grabbed the covers and she let out a gasp, then a moan.
"Jason, what the fuck, oh my
god
, are you doing this? Oh fuck yes, Yes, YES!" My little sister's legs scissored closed and she thrashed around on the mattress. Her face was flushed and I could suddenly smell her arousal.
I had used my psychokinesis to stimulate her clit and both nipples at once. Years of fine tuning my control were paying off. I could both warm her genitals and make them pulse very rapidly, bringing on an orgasm at incredible speed.
She lay on my bed in a daze, I sat next to her. I liked my sister, I also lusted after her. Her small size makes her large titties look even bigger on her. She's got a narrow waist and nice thick thighs, plus an ass I've dreamt of fucking.
"What do you think, sis? How was it?" I grinned down at her. She was looking back like she had no idea what was going on, I knew how she felt. The first successful time I'd made myself cum that way was still seared into my mind.
"Want another one?" I asked, and in a moment she was thrashing and moaning again, her body on fire as I played her nerves like a virtuoso. This time I kept the stimulation going for two minutes or so, she kept moaning and her face looked so hot, I was tempted to cum myself.
Finally she lay still on the bed, staring at the ceiling. "Jason, holy shit, don't you ever..." she began. I gave her another quick orgasm. She bucked and moaned for a moment before saying "No more, I give, oh god!"
I was totally turned on now, she looked so sexy cumming for me like that, I hauled out my already hard cock and gave myself a quick pulse or two until I shot a load all over Amber's chest. Next time, I promised myself, she'd be naked when I came on her tits.
"Here's the deal, sis. We're going to experiment together, see what my power can do. If you opt out, fine, as long as you keep my secret. But you won't opt out. The orgasms I give are different, stronger. You'll never have another one but always remember how good they are." Some of those claims were true, some BS, but she didn't know that.
I was counting on her natural rebelliousness too. She got up on one elbow and grimaced. "You owe me a shirt, ick. Okay, I'm in, I guess." With that she just pulled her cum-stained shirt over her head.
Time stopped for me, I'd been dying to see Amber's jugs for years. They were in a bra, a very nice one, but I still wanted to capture the moment. They looked so soft, so warm, I just wanted to bury my head in her chest.
Instead, I went and got my sister another shirt from her room. Hey, you pick your battles, right? Once she was dressed again she said we could talk later, she had things to do today, other than being her big brother's science experiment. But she said it with a smile.
It was mom and dad's night out, so after dinner Amber and I had the house to ourselves. We went up to my bedroom, eager to try out this new phenomenon. I wanted Amber to strip, I wanted to see if there were any changes to her skin when I used my power.
It took a little convincing but finally in the name of science Amber got naked for me. She took my breath away. Narrow waist, full bust and hips, her nipples pink and perfect. I was getting hard and right now I didn't care if she was looking, I couldn't tear my eyes away from my sexy sis.
"Jason! Focus!" Amber's voice was like a glass of cold water to the face, I remembered what I was supposed to be doing. I thought she'd be pissed at me for ogling her like that but she was smiling a naughty smile. Well!
