“Can I finish sucking you off now Foster? Or do I have to pose and show off my butt too?” My eyes snapped back to hers at that, it was exactly what she wanted to do, to feel totally sexy. Another eye roll, a tut, like she hadn’t said it just to implant the idea in my head, she practically bounced around on the coffee table to her hands and knees. Arching her back, aiming her ass right at me. I knew I’d touched it (Fuck I’d licked it!) but it looked so much better like this. “Happy?”
“I’m so happy. You have no idea.” I rasped.
“Foster!” Wanting my attention but wiggling her butt at me tantalizing, I looked from her face to that amazing booty, over and over.
“Marissa?”
“We’re staying here for a while and… We’re gonna cuddle and you can’t… You can’t say no! If I make you cum twice in one day… You can’t say no! After… For a little while we’re gonna be… Like, boyfriend and girlfriend, okay? No! It doesn’t matter! You make me feel so good about myself and… You can’t say no! It’s gonna happen!” Fuck she was cute! Shy and clearly lonely, needing not just sex but emotional connection too. I opened my mouth, she rushed in. “You can’t say no!” Doing it again as soon as I started forming a word just jumped in. Totally sure I would deny her, “Foster! Just… I’ll be really good to you and be naked anytime you want me to be, totally naked.” Her tone saying that that was a huge thing she was agreeing to, a costly promise to make for a girl with low self-esteem. “I’ll be on my knees anytime you want me to be.” She was going to be that anyway but I appreciated more promises that I could tease her with later. “Just… You can’t say no.”
I walked up to her, put a finger to her lips like she had to me earlier, then pulled it away and kissed her. She was all in on it, mashing her lips to mine, slipping her tongue out. Finding her hands as we made out I put them on my cock, which was so saturated with her spit that it was still fairly lubed. Groaning into her mouth as she double handed stroked me, as we put granny’s coffee table to the test with her sitting and me kneeling on it.
“Oh shit! Oh fuck!” I groaned, breaking the kiss.
“You gonna cum? Let me…” She couldn’t scoot down and couldn’t fold herself in half enough to get at my cock that she’d stopped stroking as I gave all the signs of being near orgasm.
“Spit on your hands. Jerk me off onto your sexy body.” I told her.
“What? Why?” The expression on her face made it so obvious she really wanted to taste my cum again.
“Because if we’re cuddling for the next couple hours I don’t want to be smelling my cum on your breath and… I want to kiss you a lot without thinking…” I don’t know if the smirk was because I’d agreed to her plea, or that she saw exactly how much I wanted the same thing.
“Yayyyyyy!” Doing a victory dance that was mostly just an adorable wiggle.
While she couldn’t get her mouth at it, she could lean forward enough, giving my stomach a lick before pulling her tongue back and letting drool go. Right off the tip and right onto the tip. Brown eyes locked up on me, hands still until there was a good amount of her drool lubricating her grip. Only then did she start stroking me hard and fast. Shifting so that her tits were resting on her forearms as she jerked me, angling my swollen staff left and right, getting it tantalizingly near her hard pink nipples.
“Cum on me Foster! Cum on me bro! I want all your white stuff! I get to have all of it for… Days! Weeks! Mine! All mine!” It started out as sexy talk, knowing I’d like it, but clearly she diverted down her own path of happy thoughts. Knowing that ten dates between Nev and I would not be done anytime soon, even if we counted today and did them everyday, it would be a week and a half. Something told me that today didn’t count and it would be weeks, at best a month. “I want it all! I get it all! You said no masturbating! I get it all! All of you for… Long enough.”
That last part was obviously a wish, a hope, a fingers crossed. She wanted it to be long enough to satiate her emotional needs, before I moved on to getting everything from Nev post date Ten. Part of me said that it was what had to be. Nev may not be the one but she was the only one of the two that I could date and marry. That I wouldn’t have to hide being with, fear getting out. But…
“We’ll make it long enough,” I promised. “We’ll make every minute count.”
“Yes! Please! Now cum on me! All over my body! Make me feel… Please! Cum!” I nodded, shifted, made a little room between us for the show.
“OH FUCK YES!” I let out, actually very surprised at the first blast. It couldn’t have been any less than the one earlier. It didn’t shoot out with the velocity, but it did what I wanted it to do. A thick line of shiny white goo going from my sister’s neck, all the way down to her right nipple. “Yes! You fucking love that! You fucking love being covered in my damn cum!” She cried out at it, grinning huge as she looked down at her chest. A puff of glee escaping her as the second shot was right on her left nipple. The third up between her breasts, and the fourth managed to get a little rocket power and got her on the cheek. Her eyes big, tongue out in her, she was too slow but did try to turn her head into it, to catch it. “You just can’t help it! Marissa! God, you gotta get that facial.”
“Yes! The money shot! Yes! I want cum all over me! Always! YOUR cum! All over me always!” The specification was important to her, I nodded and groaned as she slowed, seeing my hands go up and dialing down to the right speed before I had to stop her.
“Fuck yes! My cum. All over you. Always.” I agreed, cupping her face, using my thumb to push the semen on her cheek into her eagerly awaiting mouth.
“You’re still gonna kiss me all night, right?” But muffled with my thumb at her lips, looking up at me with those big brown eyes in a way that made me wonder how the fuck she didn’t have every guy in town at her beck and call.
“Of course.”
“I get to eat all your cum then?” Like I’d been denying her dessert.
“Of course. You get to eat all my cum.” It hit my head as nothing but a tease but before the word was out I knew it was true. “Again.”
“Again? You… Was I that obvious?” Not even trying to deny it.
“Yes, kinda.” She blushed but nodded, stroking me off even slower, nothing but pulses and droplets of seed falling from me as my sister thought she hadn’t been obvious about running out of the room and then feeding herself my cum. She hadn’t. She’d been subtle. Or maybe I’d been too distracted.
“It’s so good.” Shrugging with cum all over her bare tits was about the sweetest and sexiest thing I’d ever seen. “Feed it to me?” I nodded, I thought I would have agreed to do it even if our parents were right there telling us how disgusting and disappointing we were to them. Because she looked so good and she opened her mouth and stuck out her tongue, waiting for it. “YES! Right off… YES!”
I didn’t use my thumb, it was awkward and probably not sexy to watch but she loved it and that was all that mattered. I shifted, squatted, and used my semi-deflated dick to get the cum and put it in her waiting mouth. She either licked it away or gave it a little suck, watching me to know when too much was too much. It took longer than any porn would have stayed on the process, but it became sort of a game to us. Marissa angling herself to help, getting as much on or along my dick as possible. Finally, when we had her beautiful curvy body cleaned down to streaks and smears, she sucked on my still kinda hard cock. I let her, staring down at her and confused as to how it was only today that I could realize how fucking sexy and amazing she was.
“Should I keep going?” She wanted to, but I shook my head, it felt good but there was a hollowness in my balls that took the real enjoyment from me.
“I’ll go clean up and… You find something good to watch,” Motioning at the TV. I nodded and fell back onto the couch, she got up, got about ten steps away before giggling, slapping both hands to her ass. “Stop!”
“Don’t tell me to stop, it’s too hot not admire that god damned juicy delicious ass.” I told her, she stood there pretending like she didn’t absolutely love it.
“If mom or dad see they’re gonna think you’re a pervert.” Almost trembling with how much she loved being looked at the way I was looking at her.
“You’re probably right. Maybe I’ll be able to help myself by tonight, if you keep prancing around all sexy and naked for me.” She blinked, I guess she had not actually thought about being naked this entire time.
“Probably not but…” Shrugging, giggling as she hurried off.
I found something on TV, had to cast it from my phone because Granny canceled everything but water and power when she was away. The coolness of the house hadn’t registered until Marissa was gone for a minute, my dick deflated and the chill set in. The heat was down to probably sixty at the most. I found the blankets, had a nice layer on the couch ready for Marissa and I when she returned with a couple of sodas and her body still glorious and unclothed.
