Lines We Cross

Chapter Four

My God, was she ever a good little f**k! If it had been any easier getting myself inside, I never would have believed it was her first time. She was instinctively, perfectly rolling her hips to meet me, making the most adorable little whimpers and gasps on every thrust of my c**k. But more than anything, it was her eyes; those deep, gorgeous emerald pools, drawing me in as if to drown me in her need. She soon had me re-evaluating my assessment; I wanted to make her c*m one more time first, before I would pull out… but she was just so incredible, she was going to make it close!

Jess saved me. She was still going at herself like a fiend watching the two of us f**k, and this time the roles were reversed; Jess’s screaming orgasmic howl was more than Lila could take, and she joined right on in with her nearly on her heels. I was really, really cutting it close now, more so than I’d ever intended… but I just couldn’t stop, not right in the middle of her orgasm like that, not until she’d finished. I used every trick I knew to delay, but I was still gasping with relief the moment Lila collapsed back against the bed, immediately pulling out and crawling up to her to straddle her shoulders. I slipped my left hand into the hair at the back of her head, lifting her up to meet me as I impatiently shoved my cockhead into her mouth, and rapidly started stroking my thick, p***y-soaked shaft with my right.

“Mmph!” Lila gasped in surprise, her eyes widening, but then she smiled around my shaft, moaning happily and sucking hard, grabbing my ass with both hands, holding me in place.

“Oh, f**k!” I growled. “f**k!” as I lost the last shred of my control, my hips jerking wildly as I unloaded jet after jet of hot, thick c*m into my step-sister’s best friend's beautiful sucking mouth. She choked a little as the first blast hit the back of her throat, too inexperienced to know what to expect and guard against it. But then she started to giggle, smiling wide as she happily, greedily took the rest.

I wavered on my knees, unable to keep myself from closing my eyes against the sheer, indescribable pleasure of her soft, sucking lips and slowly swirling tongue on my overly sensitive head. I had to pull away, I had no choice! I did so with a gasp, catching myself with a hand against the wall above her head, and she let out an adorable, proud little giggle at what she’d just made me do. She let go of my ass and moved to prop herself up, staring straight up into my eyes again as she opened her mouth and stuck out her tongue, displaying her well-earned prize. But I’d barely had a moment to enjoy the sight of her like that before she’d sucked it back in, swallowing eagerly, then sticking it right back out again to prove what she’d done.

Jess was faster off the mark, beating me to a long, passionate kiss moments before I could lean down to do the same. But then she withdrew, scurrying rapidly down the bed and plopping herself between Lila’s thighs, going right to work on her other set of lips. She gasped and squirmed, not ready for the renewed attention, but Jess wasn’t taking no for an answer. They compromised with a change of positions, Lila at least getting to lay herself back down first, as I moved into place beside her and I finally got my proper kiss.

I crawled slowly up the bed beside her head, showing my c*m-covered cockhead directly into her mouth before she’d even registered I was there.

“You like that, you little slut?” I demanded as her eyes flashed open in surprise. “You like tasting yourself on your best friend’s stepbrother’s c**k?”

“Mmhmm!” she nodded vigorously, moaning around my shaft. I did, too; I’d given myself a little bit of a rest while they’d been kissing, but I was still quite sensitive, and it felt amazing having her swirling around my crown with her tongue.

“Try to squeeze some out!” Jess murmured from further down the bed. “I want to taste him in you!”

“I’m already trying,” Lila popped out of her mouth with a giggle. “But he’s really, really huge… he came so deep up inside there, I’m pretty sure most of it just went straight up into my womb! And any that did, won’t be coming out again any time soon!”

Jess giggled too, nodding her understanding; she didn’t seem too upset about it, happily licking up Lila’s mess, even if she obviously had preferred having mine added to the mix. Lila went back to work, slowly licking her way up and down my length, eagerly lapping up as much of her own creamy white juices as she could. She even sucked my big, heavy balls fully inside of her mouth, one after the other, making me gasp and close my eyes as she purred appreciatively at the taste.

Once thoroughly cleaned, I couldn’t help but lay down beside her and pull her into a deep and passionate kiss. She gasped in surprise, trying to pull away. I’m not sure why, kissing was hardly any worse than anything we’d already done! but I held her in place, and after a few seconds she gave in and melted into my embrace, our tongues dancing together as I fondled her breast, and she reached down to take hold of my softening c**k.

“You’re a good kisser,” she purred sleepily against my lips. “You kiss almost as good as you f**k!”

“You, too!” I chuckled, giving her an extra-tight squeeze of my hand on her tit, making her gasp. We kept making out until Jess had finished between her thighs, gifting her a softer, slower, and more languid orgasm than any she’d had with me. Then Jess crawled up the bed, and we adjusted our positions, with me in the middle and the girls snuggling tightly up against my sides, each with a leg throw negligently over my own, their cheeks nuzzling softly on my chest.

“You girls are incredible, you know that?” I sighed happily, holding them close under my arms, running my hands up and down their sides and softly kissing them in their hair.

“You, too!” they echoed in synch, giggling at the unintentional jinx.

“You’ve really got to give me the number of your doctor,” Lila smiled across my chest. “That looked way too much fun, having him cumming in you like that! I need to get myself on birth control ASAP!”

“Or you could just not…” Jess wickedly grinned. “And let him breed that pretty little p***y for real!”

“You can’t be serious!” she gasped, eyes and mouth wide. I was no less shocked by the idea… but then she blushed, averting her eyes down my chest and smiling guiltily. My God… she couldn’t really be thinking about it, could she?

“Even if I could maybe be okay with the idea, just for myself…” she almost whispered, her cheeks rapidly growing pinker than I think I’d ever seen. “Mom would have kittens, when she found out! And Eli being family or not… Dad would still be right up here with a shotgun, if I ever end up preggers without being married, first!”

“I can think of worse fates,” I murmured, and she gasped and jerked her head up to meet my eyes. “Lots of people have married their first cousins, you know. Albert Einstein, Charles Darwin, Edgar Allan Poe, H.G. Wells, Johann Sebastian Bach, Jesse James… And once we start talking about European royalty, it might be easier to list the ones who didn’t marry their cousins! We could be in worse company,” I smiled down at her reassuringly, and gave her a squeeze under my arm.

She took a moment, searching my eyes, then wryly grinned. “And you just had those names ready on the tip of your tongue, did you?”

“Well…” I smiled guiltily back down at her. “Just because I never expected anything to actually happen, doesn’t mean I haven’t fantasized about it a time or two. I may have looked up a few examples, just to make myself feel better about the idea.”

“Is that so?” she giggled, stretching upwards for a soft, slow kiss on the lips before settling back against my chest.

“And… what about me?” Jess shyly chimed in as well, nervously chewing her lip. “You have examples of brothers marrying their sisters, too?”

“Not recent ones,” I replied, shocked that she was even asking, trying to buy myself time to think. But, uh… the ancient Egyptians, I guess. They rather famously believed that the only bride fit for a king of Egypt was a queen of Egypt, so the pharaohs were marrying their siblings all the time. And they ruled the biggest, most advanced culture on earth for something like three thousand years, so they can’t have been all wrong.”
