"I think I'm gonna go home and get another shower," you answer. "I smell like sex and cum."
"Aww, but it smells so good!" Gwen whines playfully, her hand slipping to your crotch once again. You shiver as her soft fingers slide along the length of your soft python, still sensitive from your last orgasm. "Why don't you just stay here, and I'll make sure we can never wash that smell off of either of us..." She starts making out with you once again while stroking your cock, and you let her for a little while, but ultimately decide you really should get home and wash off.
"Sorry, Gwen, maybe later. I really think I should go." You plant one last kiss on her lips and start to gather your clothes from the grass, only to find them drenched in cum and sweat as a result of your messy lovemaking; looks like you'll have to wear cumrags home.
"Well, okay..." your mom says, sounding a little let down, "but I'll be paying you a visit in bed tonight... I'm not nearly done with you..." She sneaks one final kiss on the tip of your rod just before you tuck it away into your shorts, staring longingly at the bulge in your crotch as you slip your shirt on. She really does love this dick of yours, doesn't she?
"You sure you'll be alright?" you ask as you prepare to leave. Even if she isn't going anywhere, she hasn't bothered to even get dressed. "I can probably walk you home if you want."
"No, no, honey, I'm fine. I just need to rest a bit. Getting fucked by a stallion takes a lot out of you, you know?"
"But, aren't you at least gonna get dressed...?"
"I will eventually; it's too hot out here for clothes to begin with. Plus I kinda enjoy it; it's been few years since I've been naked in public... Oops, that was one of mommy's little secrets..." She gives you a grin that shows whatever her past was, she obviously has no regrets. After the behaviour you just witness from her, though, you find it slightly easier to believe she has a slutty side than you would have yesterday.
You hop on your bike and start pedaling in the direction of home. The whole way back your mind is full of fresh images of your smoking hot mom, lying naked on her back and begging for your monstrous dick inside her. If she keeps to her promise, which you're quite certain she will, neither of you will be getting a moment of sleep tonight; you'll be too busy glazing her with jizz inside and out.
Unfortunately, these thoughts are making your journey home rather difficult; not because you're not paying attention to where you're going (you've learned your lesson), but because your massive boner is getting really hard to work around. It flops around awkwardly and manages to put itself in the most uncomfortable positions possible as you pedal, until you eventually have to stop and let yourself calm down. You try to occupy your mind with simple thoughts about things like video games and school work until you at least get down to a half chub, then attempt to continue. It works for a time, until you feel a strange and overwhelmingly pleasant sensation suddenly build up in your crotch that forces you to stop again. It feels like an orgasm, but somehow the feeling is deeper than that, and spreads all throughout your dick. You reach down your pants and realize you're growing again!
"Bigger is better, night?" you tell yourself as your member stretches further and further down your leg. Once it stops you can see the tip of it hanging out of your paint leg, right next to your knee. And right now it's completely flaccid. "Goddamn, Gwen is gonna love this." You fumble around in your pants for a bit, in a place where all can see, trying to tuck your trouser snake into a position where it wouldn't get tangled up on the ride home. This proves difficult, as your orange sized balls take up a lot of room themselves, and you have to uncomfortably bunch them together for the last stretch of your journey.
Finally you arrive at home, sweating, uncomfortable, and still reeking of the cum on your clothes. You hurry inside and up to your room to grab some fresh clothes. You don't run into Liz along the way, surprisingly; you're even a bit let down, you're kinda in the mood to fool around with her more now...
You quickly slip into the bathroom so that you can finally get out of these nasty rags and change into something comfortable. As you pull off your shorts, you realize all the sex you've had has made you really need to pee. Brandishing your 14" softie in both hands, you step in front of the toilet and begin to relieve yourself. A torrent of piss akin to a garden hose with your thumb pressed over it blasts into the bowl. However, since you're not used to this new length quite yet, you forget that it's necessary for you to hold onto it and end up dropping it in the bowl! The cold toilet water shocks your whole member, and serves as a reminder to you that you are significantly larger than before and need to be aware of this fact.
Along with your dick and balls, your bladder must have grown as well, as you find yourself pissing for a significantly longer time than before. During said time, you can hear two pairs of small feet coming down the hallway, signaling the presence of your little siblings. You're used to hearing those energetic kids bolting up and down the house at all hours of the day, but something seems to have caught their attention, as the footsteps stop right outside the bathroom door.
"Hey, do you smell that?" Jake's voice asks.
You hear June take a few whiffs of the air before replying, "Yeah, something does smell good around here. Where's it coming from?"
"It kinda smells like Mommy and Daddy's room after they have one of their wrestling matches." Oh God, are they able to smell your clothes?! "I think it's coming from in here..." The doorknob begins to turn and you try to hold the door shut, but have to let go of your dick in the process! Again it falls into the toilet water; your piss has warned it up some, but you still don't enjoy having your dick drenched in piss water. Lacking the proper number of hands to both fish your cock out and barricade the door, you fail at both, and the twins step into the room with you.
"Hey! Don't barge in here when people are peeing!" you scold, attempting to hide your wet sausage under your shirt.
"Sorry Steven," June says without making any motion to leave. "We smelled something really good and it seemed like it was coming from in here."
"It's his pants!" Jake exclaims, snatching your dirty laundry from the counter top. Before you can stop him he presses the outturned crotch of the shorts to his nose and sniffs deeply, inhaling your musk, sweat, and dried cum. "Wow, these smell awesome bro!" He eventually passes them on to June, who follows his example.
"Hey, stop that, put those down!" You try to snatch the shorts away from them, but realize you can't keep your junk hidden without both hands, and decide that's more of a priority. All you can do is yell at them.
"But why? Sniffing them makes my peepee feel funny," says June from behind the fabric. "It's a good funny."
"Mine too," Jake adds, drawing attention to the tent that has formed in his own shorts. "Is this normal big bro?"
"Kids your age shouldn't be smelling other people's pants!" you tell them sharply. You decide you could at least try to take your clothes from them; if you succeed, you could use them to cover up your dong as well. You prepare yourself to take the chance...
...but you fail! June immediately pulls the shorts out of your grasp before you can touch them, resulting in your massive anaconda flopping down between your knees. The twins just stare in amazement as your face turns bright red.
"Close your eyes! This is private stuff!" you tell them, trying hopelessly to pull your shirt down over your meat. But, and you never thought you'd say this, unfortunately your dick is too big to hide.
"Wow, your peepee his huge, Steven..." Jake says with wide eyes as he slowly comes toward you. "Way bigger than mine." He pulls down his own pants, unveiling his own smooth, hairless dick, sticking out around 3 inches from his crotch, a sight you definitely didn't want to see, especially on his young frame.
"And I can smell it from over here," says June, her own cheeks turning red with excitement. "It smells even better than your pants..."
"Look you two. You need to get out of here right now." You may have just fucked your own mother, and maybe you even wanted to bang your teen sister, but the twins are still just kids! It'd be wrong even if they weren't family! Even though you can feel a pleasant sensation building up in the base of your dick, you certainly don't want it there. And with how big you are flaccid now, who knows how big you'll be hard?
As you feel your unwanted ere room beginning to engorge your rod, you realize this isn't the feeling of getting a boner; your dick is growing again! But the question is, in what way?
