Her mouth

The point of coming down here was to clean up, not get dirtier, you think. No point in using anything else. Looking at it now, her mouth isn't anything special, unlike the rest of her, but having everything on everyone be a knock-out 10/10 all the time would kinda get boring in it's own way.

"Uh, I was kinda wondering if you could, um..."

She patiently waits for the rest of your sentence while you stand in front of her naked, with a noticeable erection, although firmly looking you in the eyes instead of your manhood inches away from her.

"...clean my dick?"

She looks at you for a second with a blank expression, and then says "Oh? That's all? Sure thing."

She goes to wipe of your dick with the end of her sweater sleeve, but you stop her.

"Wait. That's not... I meant... with your mouth..."

She takes a second to process what you're asking, then her cheeks turn a soft shade of red as she stammers out "O-Oh. Well... you've never asked to do anything like that with me before... what's with the sudden change? You feeling alright? Your sisters do a bad job?"

"No! I mean... not at all. It's just that I don't want them to do it when you're sitting down here not getting any attention."

Well, that's mostly the truth. If your sisters got some, you might as well share the love. There's plenty to go around with your newfound stamina in this perfect world.

"W-Well John, it is a special day for your sisters, but if you say you want an old girl like me, I'll see what I can do."

She leans forward from her position on the couch as you stand over her. Her warm breath blows on your cock as she opens her mouth to slide it inside. As she does, her moist tongue runs under your glans, causing you to twitch a little. You can tell she's not experienced with this, especially with a cock of your size, but her older age means she's not plain clumsy or awkward like a virgin either.

Your mother slides down as far as she can before she gags a little, then pulling up to begin the cycle again. As she continues, she gets a little deeper each time, but her gag reflex doesn't allow her to swallow your entire dick.

"Hnng! M-mom..."

She pulls you dick out of her mouth entirely with a *pop* as she gathers her breath, before going back in for more. Another minute, and she does the same, this time looking up at you.

"Enjoying it so far, John? It's been a while since I've done anything like this. Tell me if there's anything wrong, okay?"

"No, it's great, but there is one thing..." you trail off.

"Hm? What is it?"

"I'd like to... go deeper. A lot deeper."

"Well, I don't know if I can, but... how about you just grab my head and use it how you'd like? That sound good?"

Good? That's one word for it.

"That'll be just fine." you tell her.

"Just go easy on me, please. I'm not as young as I used to be." She replies before getting her lips back on your cock and awaiting you to take the initiative.

No promises, you think to yourself. The horny has entirely taken over you, and the pressure building in your balls isn't gonna just disappear on it's own.

Everything in position, your mom rests her hands on her knees as you grab the back of her head with one hand and her braided hair in the other. Using her head, you slowly **** her down your cock, far further than her comfort zone. Almost kissing your base, a tug of her hair finally pulls her down all the way.

"GRRK!"

Her body makes a startling noise as she clearly isn't meant to be used this hard, but you're past the point of caring now. Your let her draw back to her starting position, just barely letting her off enough almost draw a breath, only to **** her back down again to your balls.

"HNNG!"

You continues the rhythm of pull and release as small tears form around her eyes and run down her cheeks.

It's time to teach this old dog some new tricks.

You pick up the pace, a blissful feeling growing in your loins as you start to near a climax. You hope you don't dump too much cum into her stomach considering her inexperience, but whatever happens happens.

"Cumming!" you yell as you pull her down again, holding her there for good this time.

The first shot causes her eyes to go wide. The second and third result in audible gulps from her throat as she tries to swallow instinctively. A forth and fifth come partially shooting out her nose. She's losing it now. Her eyes slowly start to close with a sixth, seventh, eighth, and now ninth shot. Suddenly they go wide again as a sickening rumble comes from her stomach. A tenth shot goes off before you pull out and step to the side just in time.

"I'm gonna-!"

Her words are cut off as a stream of off-white liquid comes erupting out of her throat and onto the floor with a squelching sound. She tries in vain to block her mouth with one hand, with her other reactively covering her stomach. Now that you notice it, it's almost bulging.

"Blllleeeeeecccchhhh"

She heaves grossly, and it's pretty clear what happened. Her body did not like the sudden change in diet after years of no sex and nothing bigger than a small sip of liquid going down her throat until now.

"Fuck! Mom, are you alright? I'm gonna go get a towel!"

"No, no." She almost laughs as she manually spits out the last bits of cum stuck in her throat. "Couldn't go easy on the old woman after all, huh? Just what have I been feeding you for you to get so big, and..." she observes the mess puddled up on the hardwood floor in front of her "...shoot so much?"

"I'm sorry, mom. I'll help you clean up this mess."

"I told you I got it, didn't I? There's nothing to worry about. I'm proud my only son turned out to be such a monster where it counts."

You learned the world here is pretty forgiving of anything you do, if it's in the name of sex.

A different voice comes from behind you, startling you.

"JESUS! You really don't know how to hold back, huh?"

Cindy and/or Mindy are standing behind you, attracted by the commotion coming from downstairs.

"We still going to Candy and Mandy's after this?"

Your mom chimes in now.

"Oh, going somewhere? Is that why you wanted a quick clean? Well, make mommy proud out there. Try not to break too other many girls like this." she says as she wipes off her own face with a towel from the kitchen.

Well, you're still standing and breathing, your dick still works (almost too well apparently), and now the twincest orgy is back on. You're guessing you didn't bend the rules of this world too much, although whether there's another case like your mom out there to test your hypothesis again... it's rather unlikely.

A breeze coming from a window your mom opened to air out the sex / cum smell reminds you of something. Something important.

Oh yeah, you haven't had any clothes on since you got here.

And you're not entirely sure you can let it rock out in public just yet.

"Hey, mom. Do I have any pairs of pants still around here?"

"Oh... I don't think so." she answers. "You never wore them often enough to need 'em, ya know? But now that you mention it, I think I have an older pair somewhere..."

She walks off to some other room before returning with a pair of khaki shorts.

With a giant hole in the crotch.

"I meant to repair them after they broke, but I just plum forgot after a while. I think your dick got so big it tore a hole right through 'em."

Your sisters snicker behind you. They're better than nothing, then.

You put them on, kiss your mom goodbye as she gives you a playful slap on the butt as you head out the door, and finally take in a good look at the outside world. Your neighborhood doesn't show too many signs of life at this hour, but heading further into town yields the results you look for:

Girls wearing bras, open shirts, tank tops, crop tops, jackets, basically any type of torso clothing you can think of, but with one caveat: All of them are a little too small, and many don't even cover their breasts adequately. Their pants situation is much the same, as in "barely even present". Skirts, miniskirts, booty shorts, and any type of regular pant cut down to little more than a pair of underwear in appearance. Real underwear, however, they are lacking completely, if the stray gust of wind lifting a skirt here or there is anything to go by.

And all of them seem to be nonplussed that you're wearing crotch-less shorts.

You pass by a burger restaurant that has your sisters whining to go in and grab a bite to eat. Sexy or not, annoying sibling antics are still the same here.

The urge to try out your newfound sexual freedom on some patrons / employees is strong, but then again you already have a date. And there will always be more girls to fuck in public some other time.
