It had been exactly one week since my big step sister had let me use her tits to please myself. Although it took much convincing it was still great nonetheless. It seemed as though my thoughts were correct in the sense that just getting that skin to skin contact, my dick to her tits, would satisfy my cravings for her. That was until tonight when I was walking passed her room to mine when I caught a glimpse of her naked body through ajar door. My god, she was better than I’d imagined. I’ve always looked at her in bikinis at the pool or watched as she darted back to her room from the shower in no more than a towel, but I’d never seen her fully exposed like this. Her tits swayed back and forth in their nudity all the while her ass jiggled with ever step towards her dresser.
As I stared at her from the doorway I realized I had a raging hard on for her. I thought these urges had finally gone, yet here I am standing outside her bedroom with my cock bulging out of my athletic shorts.
“If I really focus I could nut quickly and make it to my room in time to clean up before anyone walks down the hall, and she would never know. My boner would be cured, and my sister wouldn’t be bothered. Perfect.”, I thought to myself.
I quickly but quietly pulled my cock out of my shorts and began stroking it to my exposed step sister.
“Holy shit, her ass is fat. So fuckable, so round and plump, just like the pornstars online.”, I mumbled to myself. At that she turned around to see what I was doing.
“What the hell?! I thought you were done with this nasty shit?”, she said as she quickly covered herself with her comforter.
“I- I- I was just getting one off real quick, I didnt think you’d notice it!”, I tried to explain but there was no use.
“You didn’t think I’d hear you mumbling out here? Plus I would have had to turn around eventually!”
“I’m sorry, just let me finish this then I’ll be done.”, I lied through my teeth, as long as I knew I’d always have a keen eye for her.
“No, no more. I’m going to tell mom and dad for real this time, theres no getting out of this one.”
As she marched passed me to tell our parents her comforter snagged on my incredible boner and pulled it right off of her. Her glorious ass exposed to me, as well as the sides of her tits and the slowly came to a low jiggle after she stopped walking, realizing what had happened.
“Holy-“, I said.
“You skeevy little perv give that back!”
“Just hear me out,”, who I was I kidding? There was no reasoning now. I’d never outright jerked off to her before, only her underwear, and well the one time she loaned her tits to my cock, but this was a different level, “just let me jerk off to your ass and I’ll be done.”
“NO! Letting you cum on my tits was a one time thing, but I’m not letting you jerk off to me anymore.”
“Please, just lay down and let me jerk off over your ass and I’ll be done with this issue. For good.”, I lied again.
“No fucking way.”
“Yes.”
“No. I’m telling mom and dad that you’re jerking off to me and that you blackmailed me into letting you titty fuck me or cumming on my bra.”
“C’mon I’m almost there anyway, look how big I am. You can’t just leave me like this!”
“I can and I will.”
“Please don’t do this, I’m begging you. Just let me cum on your ass and this will the last time I ever jerk off to you again.”
“The last time? And no more stealing my thongs or bras for you to put your dick on?”
“Well I dont know about that, I-”
“Yes or no?”
“Fine. Yes.”, I really have a bad habit of lying. But I think that’s the least of my issues now.
“Fine. But it better be quick. I’m getting ready for a date and I still need to put my makeup on. I’ll lay down, with my ass up, just for you. But I swear to god if you pull anymore of this bulls-”
“I won’t.”
As she walked back to her room her huge tits bounced with every step. I reached out for a squeeze and
“Don’t even try me.”, she said covering her breasts.
“I’ve already came on them I dont what the issue is with me touching them, but ok.”
She layed face down on the bed with her nice, plump ass face up for my pleasure. I climbed over her and stood on my knees with my cock in hand.
I began slowly, not wanting to miss any time with her ass out. I again knew that I wouldn’t last long here. Her body just did things to me that I couldnt explain. As I began moving faster drops of precum and sweat started dripping onto her cheeks creating a nice shine on her wonderful skin.
“C’mon it’s been like five minutes, I thought you said you were close?”
“It’s happening again, it’s not enough.”, I k we I was about to cum, i was relieved she said something otherwise I would have burst minutes, maybe seconds later.
“Well, it needs to be, I have to go or I’m gonna be late.”
“Please just wait, I’m sure we can agree on something. I could stick it-”
“Absolutely not! We are not doing anal before my date!”
“Fine, you could suck me off?”
“What? That’s disgusting!”
“I would pop like a pin to a balloon.”
The silence was deafening. I couldn’t believe she was seriously considering this. After a minute of contemplation she had an answer:
“Fine. Fuck it. Get off me so I get up.”
“YES, IM ABOUT TO GET HEAD FROM HER!”, I yelled inside my head.
She slowly and reluctantly got off the bed and onto her knees in front of me. My massive hard on was staring her right in the face, as if it knew it was going to get some very special attention.
“You can’t come iny mouth. I’ll let you shoot on my tits again, but not the mouth.”, she bargained.
“Ok.”
With that her hand wrapped around me and took me into her mouth. Her moist tongue working its way around my shaft. I thought I was hard already but it seemed as though I grew even more inside her mouth. As I was lost in euphoria I hit the back of her throat. Jesus, this felt amazing. She started to pull her bead back and as my dick made its brief exodus from her mouth she wrapped her lips around the head of my cock and sucked and kissed it. She knew what she was doing, trying to make me cum without even being in her. At that I took matters into my own hands, or her mouth, and shoved my way back in. She understood what that was about as she bobbed her head back and forth on my rock.
After just a few minutes I was ready. I began to swell in her mouth as the cum was working its way to my urethra.
With a little thrust from the hips I shot my load all down her throat.
“What the fuck? I thought I said no cumming in my mouth?! You were supposed to pull out!”
“Sorry. Here, now I’ll cum on them.”
As she stared at me questioningly I stroker my cock and a few more spurts of cum flew out of me and onto her breasts. Her pink nipples were my main targets as I pointed the head of my cock at them and shooting on them.
“You asshole! No there’s cum in my mouth and on my tits!”
“Oh I know it.”
