Leonardo Lansing headed upstairs to his bedroom after getting back from a friend's. He passes his younger sister Ariel's room and notices the door was left slightly open. Leonardo looked up and down the hallways before putting his face up to the cracked door and became ecstatic at what he was in front of his vision. Ariel was a delightfully cute girl. Her style was jarringly similar to the cartoon character of Velma from Scooby Doo; a soft black Bob cut and thick rimmed square glasses. She even dressed similar to Velma usually wearing a baggy sweater or turtleneck, knee-length plaid skirts, knee-high socks, and Mary Jane doll shoes. The 18 year old had her back turned towards the door while doing the famous unshackling your brassiere from inside your shirt trick. She pulled out an enormous plain white brassiere from underneath her tee-shirt and tosses it on the floor with a huge sigh of relief escaping from between her lips. Even with her back turned to her perverted brother; her pendulous breasts were so enormous that they extended pass her sides in a nice crescent view. He instantly felt his dick starting to come to life in his jeans.
Ariel's comfy singular bed was station near the door of her bedroom. She finally turned around and headed towards her bed giving her perverted brother Leo and his lecherous eyes the pleasure of feasting on her mammoth sphere-shaped breasts. They swayed and bobbed generously under her flimsy night tee-shirt that was wrapped snuggly over them but hung far from her flat stomach that if Ariel was to raise her arms, an abundance of under-boob would show. Outside the restrictions of an annoying 30H brassiere, her monster boobs hung-heavy in the forms of giant teardrops and obtruded from her short 5'4 frame like oversized spheres. Her waist wasn't thin but it was small in comparison to her bulky enormous teen tits that dominated her upper torso. She hated her giant chest and the stares and name calling that came with having abnormally fat humongous breasts that looked shameful on her body.
Ariel was fine being called a nerd, a prude and goody-two-shoes but names like Cow girl, Tits McGee, Jumbo Jugs, Pumpkin Tits, and other obscene, lewd, raunchy, and derogatory words used to illustrate her chest size irritated her the most. Ariel has always been somewhat of a loner and never one to draw attention to herself outside of her unreasonable hefty chest. Despite the unflattering names, she got along with most of her peers quite well at school. She was on her debate team, played the flute in band, and was the class president of her high school for the fourth and final time now that she was a senior.
Ariel couldn't wait to escape high school in a couple of months and get away from her so-called peers and the immature perverted guys that only wanted to feast their hands, mouths, and hard cocks on her colossal breasts. Unfortunate for her, her older brother Leonardo fell into that category. He tried hard to be nonchalant about ogling her titanic knockers but sometimes it came off so obvious. Since the start of her substantially immense chest growth, Leo had only watched Ariel walk around a variety of places with those back-arching boulders concealed in the most casual clothing but their size was far too great to hide in anything she wore. He tumbled upon one of her massive brassieres once while doing laundry and nearly blew his load at finding out her chest size. This was Leo's first boldly attempt at ever trying to see his younger sister's majestic braless udders as he stood outside of Ariel's bedroom, the only place she called solitude.
"What you looking at?" whispered a female voice in Leonard's ear.
Leonard froze and immediately became sweaty from the familiar voice of the female leaning over his shoulder.
"Did she give you a good show?" softly asked the female's voice.
"What do you want, Meg?" Leonard nervously responded back.
"Just curious as to why my fraternal twin is spying on our baby sister as she prepares for bed," snarky replied Meg.
Leonardo hastily drags Meg by her arm to around the corner just as Ariel's bedroom door closes. Being fraternal twins, their age and still living at home was the only things they had in common. Leonardo had curly brown hair and brown eyes. Meghan had chest-level flowing blonde hair with olive-colored eyes and light brown freckles nonchalantly sparkled on her face.
"That wasn't what it looked like," Leo nervously attempted to lie.
"Cut the crap, horny boy. That thing in your pants says otherwise," taunted Meg, making reference to the raging hard-on in his jeans. "I get it bro. Our young sister has ginormous boobies and you wanna just suffocate yourself in those massive things? I've seen her topless many times and by porn star standards, she's very quite impressive. It's like she has humongous milky-white bowling balls hanging off her chest with silver dollars size dark pink areolas and nipples that look lost in her sea of massive whopping boobies. Is describing our baby sister's huge freaky fuck bags making you hornier?"
"Uh, no, of course not," Leonard boldly lied as the bulge in his tight jeans grew and felt ready to burst through the seams.
"Well, I'm going to go let you jerk off to our dork sister's giant titties or you could fantasize about this," sexually suggested Meg as she turns around and leisurely walks away from her brother, giving him a vantage look at her enormous thick bubble butt that jiggled incessantly underneath a pair of black yoga pants. As if his younger sister Ariel's ridiculous huge boobs wasn't enough problems for Leonard, his fraternal twin sister Meg was gifted an enormous bubble-shaped ass.
He drooled as Meg walked away with her plump backside jiggling about and whimpered once she disappeared into her bedroom. She was gorgeous, smart, socially outgoing and kind of a bitch. Her 5'6 lithe physique came with baseball-sized pert breasts, a flat stomach and greatly shaped legs. Her best feature was obviously her flawlessly curved ample ass that looked like she had two honeydew melons jutting out the back of her yoga pants. Her butt wasn't grossly large as it was in perfect symmetry with her well-toned thighs and legs. Leo felt curse having to be the brother of two sisters with overdeveloped charms. He knew it was gross to do anything physical with his sisters, so his lewd fantasies about them would have to do. Leo quickly headed to his bedroom, pulled up his favorite porn site on his laptop and jacked off until a powerful orgasm put him to sleep...
