An original short story written by [MtG-Ti] based on edited artwork originally drawn by InCase.
There was an awful lot you didn’t like about what you were seeing. Plenty to like too, of course, but you weren’t quite sure how the tossed coin had landed just yet…
. . .
Getting home from an especially long day of backbreaking work filled with the kind of distractions you hated the most — the ones that came as meaningless congratulations from corporate assholes you’d never seen before, wouldn’t see again, and didn’t know from Adam — all you really wanted — all you were really wishing for as soon as you got through your door — was a delicious, home-cooked meal, an ice-cold beer to wash it down with, and a smoking-hot kiss from your beautiful wife to cap it all off.
…Maybe with some tongue and a chance to grab her ass, but you couldn’t expect miracles even if it was your birthday! So when you bumped into her on her way out, well—!
“¡Ay, mi corazón~! There’s this teeny-tiny emergency I have to go take care of, but I promise I won’t be too long!” …That usually meant she’d be at least an hour, but probably longer. “I left your present up in our bedroom, so make sure you go take a look before I get back! …I love you, honey, and we’ll celebrate properly later, okay~?”
A quick kiss on the cheek and a great big empty handful of nothing hadn’t been on your bingo card, but it was all your wife left you with, so you’d just have to make do... At least your best friends at work remembered your birthday… You’d found a 24 pack of your favourite beer in your truck at the end of the day, and they’d given you even friendlier grunts of acknowledgement than usual, so…
Maybe, somehow, if the planets had aligned themselves just right, the wife had actually forgotten it was your birthday and was sneaking off to the gas station to—! …No, no, she said she’d left you a present, so there was no way she forgot.
Damn, there went that little present! God forbid you had a chance to even up the score! She’d said at the time that she wasn’t mad and appendicitis and emergency surgery were good excuses, but you could see in her eyes that she was more disappointed than she’d ever been and she’d never forget that year!
Ugh…
Trudging your way to the kitchen, you had to grab that beer yourself, and after crossing your fingers, making a wish, and scouring the fridge for something covered in plastic wrap, it looked like you were gonna have to settle for a liquid dinner…
At least until the real chef came back, lest you whip something quick up for yourself and ruin your appetite right before—
“Mmnffff~❤! Haaaha haaf-daa~❤!”
. . .
Your immeasurable disappointment had auto-piloted you right up the stairs and into your bedroom, and of all the presents your wife could’ve gotten you, you never in a million, billion years would’ve expected the one laying on your bed and staring you right in the face, ass first…
Heck, it made more sense for there to be a whole new truck stashed away inside the house than her brother…!
A quick look around to check for hidden cameras and get the lay of the land revealed the family mole she’d told you countless stories about, only, on her brother, it was on the opposite side of his face. Kinda like a mirror image of sorts, it was hard to believe they weren’t identical twins when he looked so much like—
Pap, pap, pap! started to fill your ears as your brother-in-law suddenly humped your bed to draw your attention to his surprisingly gropable-looking ass. Well, that and the sign wishing you a ‘happy birthday’ that couldn’t have been written by anyone other than your wife unless the pair of not-identical-twins shared their handwriting too…
Knowing he’d gotten your attention, your lithe prisoner tried to arch his back as best he could, but without any extra give in the ropes that were holding him down, the best he could do was drop his hips and push them into the mattress before shaking his money-maker a lot less than he seemed to want to.
Goshdarn, the ‘fuck me ragged’ eyes he was giving you really made the makeup he was wearing stand out! …Helped explain why your wife’s lipstick was smudged when she was rushing out the door, too. Thank God you didn’t go rushing to conclusions or take the hunting rifle off the wall to check all the rooms and closets!
Moving his head as best he could to try and nudge your sightline in the right direction, you followed his smouldering gaze to the bottle of lube ever-so-conveniently placed by his side, and—
Yup, there was absolutely no denying it anymore. Your brother-in-law — the spitting image of your lovely wife, albeit quite a few pounds lighter where you liked the extra meat — was tied to your bed naked, spread eagled, with a ballgag in his mouth, his hair done up in braids, and what looked to be a pair of your wife’s stockings on so you could fuck him.
Probably hard, fast, deep, and repeatedly if your wife was giving you a couple hours together… Well then, the first thing to do was remove his gag and hear the whole story straight from the horse’s mouth!
. . .
Taking a seat beside him and having to grab the little spitfire’s hair to get him to stop squirming, you finally managed to get the ballgag off so the two of you could have a civilized talk and—
“Why’d you ruin it!? You aren’t supposed to talk to me, you’re supposed to FUCK ME! How much clearer can we make it that I want your cock, and my ass is YOURS!? Do you have any idea how long my sister made me sit still for this stupid makeup!? Or this hair!? Is this what she has to put up with!? Is this why I’m not an uncle yet!? I’ve been hard for at least—! Mmmphhhhh! …Mmmppphh~❤?”
Yup, that was enough of that…
Slipping the ballgag back into place and tightening it so you wouldn’t have to hear another word or the string of expletives he was gaining momentum for, the brat you felt bad about comparing your wife to earned himself a quick smack on his admittedly soft, supple, and supremely spankable ass that got him moaning in blissful silence and grinding his hips back into the bed.
Well alrighty then…
Counting off on your fingers and getting an affirmative nod in reply each time, you took full stock of the situation you were in:
First, your BIL was a bit of a trouble-maker... A lot of your wife’s stories started to get a lot more believable now, and you confirmed beyond even an unreasonable doubt that he was into you, he wanted this, and he was a willing participant in this little ‘surprise’ his sister and your wife had planned out for you.
…The last thing in the world you wanted to find out was that even a sliver of this was unconsensual, or coerced, or something along those lines. But nope, it wasn’t. Check.
Second, your wife had arranged all this as your birthday surprise... She wasn’t gonna get back in an hour, find the two of you entangled with each other, and pull the hunting rifle off the wall herself.
…Her brother had her permission for what was clearly supposed to happen and more importantly, so did you.
Third, given the… circumstances, you were free to do whatever you wanted, within certain limits, even if your ‘plaything’ for the next couple hours shook his head at that idea. Another slap and an extra-hard grope had him mewling into his gag and leaking into your sheets, which would undoubtedly need to be changed at some time that night…
With that covered, the three green lights you got meant GO, and you were clear for liftoff.
So, teasing your birthday present by taking off your clothes one piece at a time as if you had all the time in the world — your strip-tease act earning you some especially frustrated and bratty thrusts into your mattress — when you reached for the supplied lube to slick up your raging boner until it shone even in the low light of the room thanks to your curtains being drawn — couldn’t afford to scare the neighbours and start a scandal, your wife no doubt agreed — all that was left was kissing your free-use onahole’s tight little pucker with the tip of your beading cock and—
Teasing him even further by exploring his body with your hands, eyes, and mouth instead... He was indignant at first, but a quick nibble on his earlobe shut him up in record time.
. . .
The wife would probably have to burn your bedsheets…
Her brother was especially sensitive, and especially tight based on the way he clenched down on the tip of the finger you’d started to worm inside him, so if you were going to be his first man — something else he confirmed with a nod, even though it took leaving a hickey on his neck to get him to admit it — and get him to relax, you’d have to dial up the foreplay.
The odd poke and tickle turned into a full-on massage that worked its way from his wrists to his ankles with an extended stop at his cushy ass, drooling cock, and clenching nuts, and by the time you started leaving bite-marks on his ass and shoulders, the wet-spot that had to have been underneath him the whole time was nearly as wide as the subtle flare of his hips.
Gosh, getting to spend so much time playing with his ass and comparing it to the one burned into your memory, you definitely saw the family resemblance…
Your wife’s ass was bigger in all the ways you loved — you’d proven that time and again as you worshipped every square inch of her at one point or another — but her brother’s was compact in different but just as good ways.
His hips were smaller, but still fit your hands perfectly, and the realization that you were going to absolutely ruin two members of the same family only made you start to breathe harder.
As much as it pained you to even think it, his ass was travel-sized… You could easily imagine him bouncing on your lap during a long-distance road trip, or squeezing into tight quarters with you and hotdogging your drooling cock until you painted his back white… Maybe even the back of his neck if you were especially pent up that day!
That was the way you wanted him, too. Out on the road, in some desolate parking lot, or in the bed of your truck — hell, even up against the hood would do — before coming home to your darling wife and sating fire his body would only stoke in you by making some of your pictures fall off the wall.
It was the thought of having both of them in one night, maybe even painting both their faces at the same time as they kneeled right next to each other, two tongues outstretched and sexy moles practically kissing as they crowded in not to spill a drop, that had the fattest bead of pre leak onto your BIL’s ass and start the kind of full-body shiver that meant he didn’t have long before he either came hands-free from your teasing, or blew a real load with you balls-deep inside him.
…Poor thing clearly couldn’t take much more, and he was plenty loose and tenderized already, you figured, so brushing one of his pigtails out of the way and peppering his face and still-gagged mouth with kisses, one extra-gentle push from your hips sent your rager sliding effortlessly inside him and his white-hot cum spurting out.
Welp, maybe it was a little bit of both…?
Cumming just from your initial penetration, he struggled and fought like a bucking bronco, but two pairs of fingers teasing his nipples and a pair of lips working their way up and down his neck made him relax and really go crazy around your cock, clenching and massaging and trying to tenderize you so he could get the balls-deep filling he so clearly wanted!
If the ballgag hadn’t vacuum-sealed against his lips when you hit the end of your length and the start of his prostate, you would’ve heard the most girlish whimper-moan imaginable and probably cum on the spot too, so it was a good thing that gag was doing its job and keeping his mouth shut.
Looking over at the bedside clock near the wall, there was an awful lot of time left for you to ‘savor’ your ‘gift,’ and since you could hold out almost indefinitely if you really focused on it, better to make the most of this once-in-a-lifetime opportunity and teach him the kind of lesson that’d really stick.
Give him one hell of a story to tell your wife when he eventually woke up from the cumatose state you were deadset on putting him in, too…
The fear in his eyes was replaced by craven lust after just two thrusts, and with an extra squirt or two from the bottle of lube, you were gliding along his insides on the hunt for the little pleasure button that would— “MMMMMMMMMMMMMMMMMM—! MMPH, MMMMMPH, MMMMMMMMMMMMMMPH~❤!”
…Damn, guess he shared a hair trigger with your wife, too~!
. . .
F-Fuck, you were getting pretty close to cumming yourself…
Your ‘sister-in-law’ was clearly throwing every trick in the book at you. His ass squeezed and clenched with the kind of rhythm and grip that gave you flashbacks of the last time you’d been intimate with your wife. There was no way something like that was genetic — right…? — so the two had clearly exchanged notes ahead of time to make your present the best it could be.
They’d damn well succeeded because creaming his hole beyond recognition was becoming more and more attractive of a prospect with each fevered thrust and squeak that leaked out around the gag in his mouth, but even as the sweat on your brow started to pepper his back and you felt you were starting to run on fumes, you still wanted to make sure he was enjoying himself.
“Mmmmmppppppppph~!?”
The fear in his eyes as you started to pull out and untie his wrists and ankles was short lived once you turned him over and hiked his legs up to slide back inside him, all without touching the gag still in his mouth.
“Mmmmmmnnnnn~❤” was the sort of reply you were waiting for as you watched his cock shiver and dribble another load onto his stomach instead of the bedsheets this time.
…If he was your present — if you were really free to do whatever you wanted to him — then you wanted to see his face as you came in him. You wanted to wrap your lips around the ballgag he was biting down on and share an admittedly awkward kiss as you wrote your name all over his insides and—
Interrupting your heartfelt monologue to wrap his arms and legs around your body like you’d just set off a bear trap, you could feel the warm little spurts trapped between your stomachs as he came like the submissive little bitch he wanted you to treat him like.
…THAT off-handed comment earned you a flex of approval and the deep back-bend your toy had been waiting to show off for a while already, inching your cock that much deeper inside him until you imagined you could clearly see the imperceptible bulge in his smooth belly you were solely responsible for.
Abandoning your mating-press ideas, and wrapping your arms around your sexy little lover, all that was left was a jack-hammering sprint to the finish.
Up and down, up and down, you forced every little bit of yourself inside your male-wife again and again, making sure you earned the deep tongue-kiss you’d been wanting all along once he finally noticed you’d undone his gag.
His lipstick became a smear on the side of your face, and as hyper-sensitivity set in and you heard the bedroom door opening behind you, your pupils grew to the size of saucers and you flooded the bussy you’d started to fall in lo—
“...H-Hey sis~❤ You’re right on tiiiiiiiiiiiiiiiiiIIIIIIIIIIIIIIIIII—!”
The sound of your wife stalking into the room wearing your favourite pair of high-heels — the click-clack against the floor unmistakable because it meant you were getting lucky any time you heard it — opened your second floodgate and basically flatlined her brother’s brain as his cock matched yours shot for shot and rope for rope, his greedy hole having to go up a size as your wife’s lips touched your cheek again and your cock grew a full size.
“...You have no idea how happy it makes me to see my two favourite boys getting along~❤” she breathed, her voice pure sex and her long, manicured fingernails scratching the secret combination on your back that made you get harder instead of softer by the time she grabbed your ass.
There was no denying the authority in her grip, and as you straightened your back and all but purred for her, her brother did the purring for both of you, hitting his own face with the last dregs of his latest orgasm thanks to the position you’d unconsciously put him in.
“I hope you’ve got seconds, mi amor… Your birthday doesn’t end until the stroke of midnight~❤”
Looking your wife dead in the eyes like a little boy might look up at a nun clutching a yardstick, all you could do was smile. Even though you were walking a tightrope with no safety net below you, you couldn’t deny the feeling that this was going to be your best birthday yet…
