Sisterly Love, Chapter 2 (The Eventful Day)

By Nictatew

Kane blushes softly as he feels the pull-up being pulled up his furry legs and over his sensitive parts. It takes everything in him to not let out a moan. He groans faintly with a blush as Trina asks what they were going to do today. "What? You mean I have to leave the house with this thing on?" Kane questionably says, not seeming keen on the idea of walking around outside of the house with a pink pull-up on under his shorts.

Trina just giggles at Kane's childish complaining, know that he's embarrassed about wearing a pull-up. "Well of course you do, in fact we have several errands to run today. We need to go grocery shopping, get the car washed, and maybe even get some new clothes today."

Kane groans again, still pouting about this whole ordeal but knows he's not going to be able to talk his sister out of anything she has her mind set on. Kane sighs softly "Alright fine, just give me a minute to get dressed."

Trina smiles and nods; walking over to her closet to go get dressed for the day. She smiles as she removes her night clothes and replaces them with a silk bra, pink and white stripped panties, a light pink tank top and a pair of tight pants that show off her ass.

Meanwhile, Kane is over on his side of the room getting ready for the day as well by picking out his clothes. One look in the mirror makes him blush at the site of himself in only a pull-up, but he quickly shakes off his embarrassment. He grabs a pair of baggy pants, hoping they conceal the thick pull-up underneath them. He also grabs a green and orange tee-shirt.

With both twins ready to head out, Trina grabs her car keys and they head out to the car. When Kane sits down, he emits a crinkle. This makes Kane blush but only makes Trina giggle at Kane's embarrassment. Trina starts the car and they drive off towards their first errand, the grocery and clothes store. Once they arrive at the store, they both get out of the car, Kane just a little behind Trina, checking his pants in case they start slipping, not wanting anyone to see the pink waistband.

Trina starts grabbing all kinds of different foods, thinking about what she wants to cook for the next few night's dinners. Meanwhile Kane is slightly fidgeting behind Trina, barely even noticeable to anyone that was far away, but Trina has been keeping an eye on him, watching him squirm with a giggle. Finally they get all the food and clothes they need and by that time, Kane is starting to get desperate but still says nothing for some reason. Trina only shrugs and heads back to the car with Kane close behind.

Kane sighs in relief as he gets in the car "Is it time to go home yet?" He asks, hoping the answer to his question is yes.

Trina smiles and shakes her head, "Were not actually, we still have to go wash the car then we can go home and relax.

Kane squirms more, hoping there is no line to the carwash so he just nods. Once they get to the carwash, Kane frowns as he sees a line of about 5 cars in front of them, a normal occurrence but he was just hoping he would get lucky.

Trina smiles as she gets in line for the carwash. With every passing second, Kane squirms more and more.

Kane groans softly, his stomach gurgling as he clenches his bottom, wanting relief terribly. "Ooh" he says to himself "That Mexican food didn't agree with me at all" He says with a whimper. He squirms as they are finally next in line to get to the carwash but he doesn't know if he can hold it much longer!

Trina pays for the carwash and they pull in, watching Kane squirm.

Kane blushes hard as he lets out a loud smelly fart, muffling into his pull-up. "Ooh, I don't think I can hold it much longer" He says out-loud, clenching his ass cheeks together with both his muscles and hands, making Trina giggle and playfully wave a hand in front of her nose.

Trina giggles "Phew, looks like baby bro needs to make a stinky doesn't he?"

Kane blushes hard "N-no! I just farted a little" He says obviously lying as they go into the dark tunnel of the automatic carwash. He whimpers softly as he wonders if he can make it.

Trina smiles as the tracks take hold of the car wheels and pull it forwards threw the various soaps and brushes throughout the car wash. The car jerks to a stop at the tracks stop as various areas.

The jerking of the car is too much for Kane and he whimpers as another loud, wetter fart escapes him. "I'm sorry sister!" He says as he lifts his butt out of his seat. *SPLORCH**BLART* PPPHHHRT* *SPLORCH*. Are just some of the sounds that echo through the car as Trina guesses are coming from Kane's pull-up.

Kane blushes and groans as he scrunches his face some, his butt still off the seat some as he pushes piles and piles and mushy, messy, runny, smelly, shit into his poor browning pull-up. He blushes hard through the entire ordeal as the mess fill his poor pull-up to the very brim of its capacity.

Soon, it comes to a slowly end as he feels fully emptied out of all his poop, having pushed some out just because he was already messy so why hold back. He hesitates for a moment before slowly sitting back down with a soft moan.

Trina watches this happen from beginning to end. She tilts her head as she hears the soft moan as they finally leave the car wash. As they are driving home she notices.... A lump in the crotch of Kane's pants that she knows isn't poop....
