shower time!

"Let's go," she commands. "It's not too small, but it will be a tight fit to wash properly. I won't mind helping you wash." After you get up, she pulls you by the hand to her bathroom. She starts up the water and then pulls you in with her after it is the right temperature.
It is a standard size, but for two preggos it is a bit tight. Only one can catch the water at a time while standing. You squat down after getting wet so Amy can too. She giggles as it puts you right at her hard cock. This thing gets hard all the time! You have seen it soft, so it can be. How does she have the energy to keep it hard, though? You ponder it as you swallow Amy's precum. When did you put this in your mouth? You don't even remember.
"Why do you always want to play with my penis?" Amy asks you.
You pull it from your mouth and put it between your tits before you say, "I didn't remember putting it in my mouth. Only when I swallowed did I realize what I was doing." You start rubbing her cock with your boobs.
"No way! Really? Like subconsciously?"
"I guess?"
"Haha, this is hot! I have you trained to service me subconsciously!"
"I don't mind. I have this wonderful shape and if it constantly gets you hard, I will have to get you off every time. ...Right?" You don't really remember thinking that through.
"Right. While you service me, I'll start washing us."
Soapy suds begin to drip down on you from above. You see Amy half-washing and half-admiring herself. She cums violently between your breasts.
"Nothing like admiring your own sexuality as a cause to shoot," she says. "Here, start doing my lower half," she orders as she hands you the soap.
You start with her cock and balls while they are on reload. Then you do her expansive belly. Her swollen rear is next as she carefully turns around. You do her legs next, back then front again. Then she sits on the back edge so you can wash her lower legs and feet. After you finish she allows the shower to wash off the suds.
"Turn down the cold a little," she tells you as she takes the soap back. You stand up, turn around and bend over to turn the cold knob down. You feel her foot on your butt, running over it.
"Better?"
"A little more," she says, running her foot between your cheeks.
"Now?"
"Now," she says as she pushes her foot into your butt. "We have been neglecting you."
"A little."
"So," she says as she ends up with her whole foot in your butt, "They said you could take long things in you." Amy starts pushing into you deeper. "You want me to stick my dick up there?"
"That's not your-"
"...Once I get to it?"
"You mean...?"
"Yes, once your ass gets there."
While previously rather skinny, her legs were well toned. Her ongoing growth has began strengthening her legs. While not what you would call thick, they are larger than they were.
"Once I get there, you will probably need it."
"Back up then. More, I'll bend my knee for now."
"I'd rather be going down than back."
"Oh, I can do that."
Amy starts lifting her leg up. You follow until you are standing perched on the edges standing above her. Her leg is almost straight up.
"Flexible much?"
"It's not that comfortable, so don't dawdle. I'll pull you down if you do!"
She wiggles her toes inside of you for emphasis. You slowly allow gravity to pull you down. It's obvious after mid-shin that the length will require talent. You hope you have it as you stop holding yourself up and let gravity take you. You get a bit further quickly but then progress slows and you feel your insides...shaping around it? You can't explain the feeling as you get to her thigh. Now your hole will begin to stretch too. While often uncomfortable, you still get satisfaction from taking larger things up your butt. The thrill always keeps you going. Amy rests her hands on your hips at this point. You turn your head to see her staring at where her leg disappears.
"Like what you see?"
"Yeah, it just...well my leg feels...I don't know. I do like what I see, don't doubt it! How do you like my thigh? Thick enough?"
"Let's just say I hope you thicken up," you tease.
"Oh really? Move up a bit, I can use my other leg too." You feel her start to run her other foot between your legs.
"No, it's fine like this," you try to convince her.
"Nonsense! I'm not playing around. Not completely anyways! We need to be able to be able to take a fully grown and curvy shemale in our holes. Ones whose curves may be greater than our own, too! We can't completely fool around just for pleasure, no matter how good it feels. So you say you need more girth, I will give you more. Don't feel ashamed. I know you have a craving for big things, cocks preferably, and I hope I can fulfill it myself one day. If you need more than I can give, we can think of something to satisfy your needs. I have plenty of big things around here we can use. You aren't the only one with a serious fetish. You have been so attentive to my cock. You let me stick it in your holes whenever I wanted; let me pump my cum into them without complaint. So let me help you with what I have."
Amy pulls you up slightly by the hips, and slides her other foot in along the side of her leg. You raise yourself up as she forces the other foot in and then aligns her second leg with the first.
"Oof, squashed my balls for a sec. How am I supposed to sit with these things dangling here?"
"Sit with your legs spread."
"Really? Or just so you can stare?"
"Yes, but that's a good point too. I'll make sure to stare," you tease.
"Oh, I wasn't accusing. You can stare at me all you want."
"I was joking about the second leg," you admit.
"I know. You should have known better. But now you will have to finish me off. Not like you can stand high enough to pull off of my legs."
You see you managed to get down to her knees. You should have kept your mouth shut. You let your legs stop holding you up and hope you are good enough. You feel Amy's thighs start to creep into you as they stretch you wide.
"How's my ass look?"
"Yummy. Look down, your butt cheeks are sticking out to the sides, displaced by my sexy thighs."
They sure are. Amy puts her hands on them. You put your hands on hers. You turn to look at her again as you slowly sink a little bit at a time. You get displaced more and more as she penetrates and stretches you further.
"Ah, I don't think I can go down anymore," you tell her.
"I'll help. Don't worry."
She starts pulling on you. Lightly at first, but pulling harder until you are moving. Her desire pulls your ass open wider than you thought you could be. You soon feel her dick poke your ass. She stops pulling you down long enough to position it. Despite the girth in you already, you feel it enter you when she starts pulling again. Just a minute longer, and your ass is sitting on the edge of the basin. She cums.
"That was amazing. You are amazing," she gushes.
"You helped me. And it was rather uncomfortable."
"How about now? Still uncomfortable?"
"A little, it is sore from the stretching. And I can see your legs outlined in my front."
"So I guess taking my ass, belly and tits is out of the question?"
"Yes," you try not to say too quickly.
"My butt isn't even that big. You could take it! Come on!"
"I'm sore, no more for now."
"Later then. Well give me back my legs!"
You bend forward and move away from her as she pulls her legs out. Once she does, your cheeks come back together with an audible slap.
"I think I deserve a wash now," you tell her, putting the soap back in her hand.
"Certainly, sweet cheeks."
Amy immediately starts washing your ass. She takes the time to bury her arms to the elbows as she cleans between your cheeks. Charming. Besides that detour, she manages to finish washing and groping you.
After washing, you help each other dry off, then she leads you to her bedroom. "Our bedroom," she emphasizes.
