Join your brother downstairs

With a fresh box of tissues in hand, you return to your brother's bedroom and replace the empty container. It's only then occurring to you... why are you helping him? Whatever, at least you'll have a fresh supply of tissues available just in case your pussy gets wet and messy again.

You eventually move downstairs and approach your brother in the living room, he was in the middle of playing Rainbow Six. Of course you greet him with a firm smack against the back of his head. "That's for making shit up and telling Gwen that I'm your girlfriend. What the fuck, man?" Upon grabbing another controller, you join his match and decide to get your **** for that betrayal.

"What? You can still tell her whatever you want, none of my business," he retorted in that smug fashion only a little brother can muster. Your parents spoiled him way too much! It's probably why he's got those extra pounds too, instead of being in good shape like you and Gwenny. If he would actually take care of himself, he might even be able to find a girlfriend instead of being a useless nerd. He takes a moment to think before coming up with another response. "Tell you what, if you manage to beat me, I'll fix the whole situation with sis and even take care of explaining everything to our parents. If I win, I get to bareback your pussy. Deal?"

That's... kind of a reasonable trade, especially since he utterly sucks at ego-shooters. All it takes is to faceroll him once and then you can literally just lean back and have everything taken care of until you're back to being a guy! Sweet! "Sure, prepare to die again you idiot." The next round starts, and you navigate your avatar to shoot down the remote cameras near your character before crouching down and sneaking into the building with your objective. You're careful not to give away your position, and keep aiming down your sights to be ready to strike as soon as you see Jimmy's ingame avatar.

There's some distracting noise coming from the kitchen -- Gwen probably -- but you ignore it and concentrate on the game. After all you're not playing a 'best of 3' match type. One kill, one win. You gotta make it count!

You continue sneaking inwards, scouting around the corners, until you hear some movement from a nearby room! That's gotta be him! You're just about to peek around the corner when you suddenly hear your sister's disgusted voice from behind -- "Jimmy! Tell your gross girlfriend to cross her legs, the entire room stinks of pussy!"

"What, no!!" Immediately you turn around to glare at her. "It does -not- stink of anything! I dried it off and everything!" She gives you a perplex stare without even attempting to hide her disgust.

"Maybe try taking a shower next time you lazy slob? Seriously Jimmy, where did you find this girl? The dumpster for damaged goods?" As if it couldn't get much worse, you suddenly hear the familiar sound of an M4 shooting a few rounds into your avatar's head. The screen turns red.

"God damn it Gwen!" you hiss back at her for making you lose! You had already practically won! God. Damn. It. You're just about to jump off the couch to slap her around when you suddenly feel Jimmy's hands firmly grabbing your waist and peeling your shorts right down to your ankles. "Seriously?? Not now! That wasn't even a fair match!" you point out, but he's persistent.

"A deal is a deal, time to give up that pussy!" He was cheerful and excited, but the way he phrased his words also sounded a lot like he's completely forgotten that your vagina is a part of your body, not just some random fleshlight! He was treating your lady bits like little more than some convenient thing to get his dick wet ... Your sister also wasn't happy at the unexpected turn of events, after all she had no clue of the arrangement that was made before the match started.

"Seriously? You two are going to fuck on mom's couch? You deserve each other... man this is depressing... I'm out." With that said, she returned to the kitchen for another moment before going upstairs and abandoning you completely. Jimmy in the meantime already succeeded in revealing your neatly shaven cunt once again, and the cute slit that served as entrance into your baby chamber.

It didn't even occur to you this time around that you were unprotected -- of course you are. All that knowledge of convenient and reliable birth control methods had been erased from your mind, for good. You still knew what a condom is, but that wasn't part of the deal you made with him... unfortunately!

While tugging down his pants, your brother maneuvered you to lie flat down on your belly while he got busy on top of you. "Can't we just... do this later... or something..." Your words fall on deaf ears while you can feel his hand grasping his semi-erect appendage and rubbing it up against your vag. Attempting to find the hole. It takes him a few tries before he finds just the right place and pops back into the damp, warm comforts of your cuntflesh. The silky texture wraps around his manhood immediately, doing what it's designed for! A slippery cave to coax a guy into dumping a load of cum inside. You can feel it -- an unpleasant presence stretching your womanhood and making room for his dick!

You're glad Gwen doesn't know the truth after all, about the way your little brother was getting to fuck and potentially inseminate his older sibling. It was getting even more embarrassing when his steady back and forth began coaxing slippery noises right out of your womanhood. Sounds of approval, probably. At least your pussy was having a good time... you cross your arms in front of you and lower your head onto the armrest while enduring this awkward torment. Getting mated by your own family member. Maybe you should keep it a secret after all...

As he keeps plowing into your vagina, you remember to point out another important detail. "Don't you dare forgetting to pull out, I don't want any of that gross slime to get inside me!" You wriggle your bum a little and grow even more aware of the presence of his chubby cock, buried inside your lady bits. His little squirter was wedged nice and deep in your body, and he still kept moving in and out of you at the same boring, rhythmical pace. "Did you hear me? Pull that thing out before you make a mess." Yet he still kept going, in and out. The entire room was quiet except for the constant squelching noise of unprotected intercourse. Your cunt was ready to receive every drop of baby-making spunk he had to offer.

"Almost... almost...." You impatiently lay underneath him, waiting for him to finish up until you grow vaguely aware of a spreading heat in your loins? It also began to feel much more... lubricated? Oh come on! He suddenly pulls out, and you feel a few remaining drops of warm semen splattering across your butt cheeks. There's no doubt that a huge majority of his cloudy pool of sperm had been safely deposited right up against the far back of your cunt. "What the fuck man!" You instantly squirm to get free, but it took him another moment before he rolled off to the side. His flaccid dick was glistening with the ripe mixture of your pussy juices and remnants of his cum.

Ugh.

You reach down to slide your boxer-shorts off your ankle and use the fabric to wipe away the gradual ooze of semen from your violated slit. The puffy lips of your vag did little to stem the flow of his spunk. You could even feel the way it was leaving your body, like... a sensation of heat and wetness deep in your core that yielded to gravity and... leaked out of you? Ugh...

After wiping your private bits a few more times, you get up with spread legs and hold your underwear up against your crotch while glaring at your bro. "This is your fault, idiot! I told you not to cum inside me! You're never gonna get a girlfriend if you can't even control your cock, you dickhead! My entire crotch feels like some shitty cream-filled donut!" It didn't manage to put him in place, all he did was smiling in satisfaction. He already won this round and he knew that pretty well. Your cunt simply continued oozing a steady flow of baby-gravy and you could feel it beginning to soak through the fabric. Surely there's some more graceful way to deal with this? Why would chicks agree to a minute of fucking if they afterwards have to deal with an hour of trickling semen like some leaky faucet? Seriously, girls must be crazy to even consider agreeing to a lurk-warm injection of sperm into a place that's so difficult to clean up after.

As you stand there with your brother's deposit making its way out of you, you're beginning to remember another pretty important detail! Sperm can swim a distance of nearly an inch every 15 minutes, and right now those little bastards were probably already giving your cervix a few affectionate kisses while trying to locate that tiny hole leading into your womb! Gotta take care of that right away! As embarrassing as it may be, you rush upstairs and into the bathroom while holding your underwear snugly pressed against your lady bits. You quickly step into the shower, turn on the warm water, and hold the shower-head under your crotch to allow the strong pressure of water to wash away all that icky spunk!

"Ahnn!" Some of the water splashes right against your sensitive clit, which is ANYTHING but pleasant. It's like getting kicked in the balls, but ongoing. Thankfully you do manage to aim a good amount of water into the spunk-filled hole of yours, where it matters. You keep it up for a solid minute before you're confident that all that cum has been washed out of your important parts.

2 hours done, 46 hours to go...
