"Hey Trent," said my sister, Kylie, "Can we still fuck even if Whitney isn't around? Or are you guys so 'in love' that you can't do that?"
Ah jeez, I thought. At first, living with my sister and my fiancΓ©e seemed like a good idea. We could save some money until we found a perfect place of our own. The first couple of days were smooth sailing, but then we hit some rocky coastline, or something. Whitney began to get a little jealous of my relationship with Kylie. Whitney should understand that brothers and sisters go way back and there will always be little inside-jokes or innuendos that she's not aware of. She wasn't there 19 years ago when some little thing happened in our childhood. I needed to try and turn that around. By asking her to marry me, I thought that she would understand I was serious... but... who knows.
"Yeah, um, Kylie, I don't know. I was going to go to bed early."
My little niece, Jesse, was already in bed asleep this Saturday night, and Whitney was pulling some weekend duty at the hospital. The Sister Bitches were supposed to come over and we were going to have a massive orgy, I hoped, but Whitney had to work and we pushed it back.
"Fine by me," snapped Kylie. I started to pack up my computer stuff and was going to head upstairs "I'll just sit down here, and watch a movie or something."
Kylie turned back to the TV. She was showing her profile and I could see her as she unbuttoned her shirt and, with two hands of course, brought a large tit up to her mouth. She opened her mouth and began sucking her nipple, some milk dribbling out the corner of her mouth.
Kylie leaned back on the couch, and then she grabbed both tits, squeezing them playfully. A fountain of milk shot up from each nipple, spraying onto her stomach, her own tits, and some even hit her face and hair. I couldn't look away.
"Look at this, Trent! Can you believe all this milk? Mmmmmmmmmm... feels so good... my tits need this... oh yeah... whaddya think, brother? Hmmm? You like? I know you do."
She pushed a boob to her face, with her chin she pushed the titflesh down so the nipple area bent to her mouth. Sucking hard, she swallowed her own milk while she continued to squeeze the other nipple which still sprayed milk all over her.
I just stood there, not answering. But my body responded. Oh yes, it did.
"Okay lame-oh... you don't want to fuck me while she's away. Fine! Then just watch."
She looked me in the eyes as she raised her hips and took off her shorts and panties, revealing her perfectly bare pussy.
"Oh kitty... yes... mmm so nice," she purred as her right hand found her pussy and she began massaging herself. Her middle finger slipped down out of my view.
Fuck!
Why aren't I jumping on her? My own sister is masturbating in front of me and I'm just standing here! It isn't like we haven't done it before, quite a few times, actually. Dammit Whitney, I hope you understand the difficulties I'm going through!
Kylie's ring finger disappeared inside herself. She fucked her pussy and kept her palm on her mons, massaging her clit. And all the while with her other hand she squeezed her tits. First one, then the other. Kylie covered her own face with milk droplets. Sometimes they joined together, sometimes they didn't but all the milk dripped down her cheeks.
I undid my pants, and dropped my drawers. Hey, I wasn't going to fuck her. But we had no rules against masturbating! Pre-cum emerged from the tip of my cock. I rubbed it around the head and down the shaft.
"That's it Trent," Kylie spoke softly. "Get out that big boy. I like him, very much. I like him in my mouth... mmmmmmmmmm... and between my tits, fucking them... and in my ass... like it did the other day when he just surprise-fucked my ass... oh shit, yeah! "
I stroked my cock, hardly daring to blink fearing I might miss something.
Kylie let go of her tits (booo!) but then moved her left hand to her cunt also (yay!) so she could really rub her clit better. All four fingers of her right hand worked hard in and out of her wet and sloppy cunt. The squishy sounds drove me nuts.
"This could be you, Trent. Right now, you could be fucking me... or eating me... God I wish you were eating me... eating my cunt... you know you want me... your sister's cunt... you want to suck and fuck your sister's cunt... you like having a slutty sister? Yes, I can see you do. How much jizz have you spilled because of me? Huh, big boy? Gallons? I guess you're just going to keep jerking it. Oh, watch this!"
She shifted on the couch, hiking her leg way up the back of it, totally spreading her legs out obscenely. She reached around with her right hand behind her ass cheeks, and her hand appeared from underneath.
She placed her middle finger right on her little ass bud. Her left hand massaged her pussy, I could see fluid oozing down her crack to her asshole.
"Should I Trent? Should I put my finger in my own ass? It's not right is it... okay I won't... oops... I didn't mean to do that... all by itself... oh shit Trent I'm fingering my own ass... boy, if Mom could see us now, huh? Me fucking my own ass for my brother..."
Mesmerized, I just stroked my steel cock. Those cum sensations were building up; at first far away, but rapidly approaching.
"Jesus Trent! My milk is still leaking and I'm not even touching my tits! Ungh... I'm trying to get two fingers in my ass... what's the matter? Come on, give it to me, baby, give it to me!"
I took a couple steps closer to my sister, and I let my cum fly. The first shot went about four feet up in the air, I shit you not. It splooshed down on Kylie's stomach and arm. The next shots fired almost as high and they splashed everywhere; pussy, tits, neck... glorious. Fucking glorious!
Kylie gripped her cunt hard and shook it, and she let loose with a few shouts of 'fuck yeah' and 'fuck you Trent', and a few 'oh shits' for good measure.
Kylie licked her left fingers of their pussy juice. She still worked her asshole with her right hand. My hard-on didn't go away.
"Are you done, Baby Brother? Cuz if you're not... you could fuck my ass and slap my tits... I know you like that."
Fuck, Whitney! Jesus Christ! Why are you working tonight? Fuck!
I shook my head, mumbled 'sorry', grabbed my pants and went up to my room. Breathing hard, I tried to calm down, but I couldn't get the vision of my masturbating sister out of my head. Then my cell rang: Whitney.
"Hey babes!" I said, hoping I sounded rested and not out of breath.
"Hey hon, whatcha doing?"
"Nothing. Sitting in my room watching Youtube. Fucking Russians, they just can't drive."
"You sure?" Whitney was fishing; she probably thought I was fucking my sister. I almost was.
"Uh, yeah I'm sure they can't drive. Why?"
"Oh nothing, just wanted to make sure you had something for me when I get home in the morning!"
