left alone

After they had finished their milkshakes and set down their glasses, the three settled into watching movies and chatting - the movies were mostly background noise, but Becca was often a little more distracted because she hadn't seen them before.

Eliza noted Becca's empty glass and sent Tara a message, "omg she drank the whole thing" Followed by a sick emoji. No sign of her 'extra' flavorings left over.

Tara replied, "wonder how she'd react if she knew what she drank lol"

"lets see if she recognises the smell?" With a thinking emoji.

Eliza looked at her sister, and then Tara, and announced, "Let's play 'Would you rather.'"

Becca was a little invested in the movie, and was about to ask if they could play later, but then Tara spoke, "Oh that'll be fun. I'll start." Becca didn't want to be the boring one, so she turned her attention to the girls.

"Would you rather be super pretty or super smart?" To Becca that was an easy question, smarts every time, she had a much greater respect for academic achievement over shallow looks. But she wondered if she should say that - was that insulting to say? She didn't want to be rude.

Eliza was in thought for a moment before she said, "Pretty." That was obvious, Becca thought. But then Eliza gave her reasoning. "Being smart is good, but people treat you better when you're pretty - you can be smart and people will still be mean to you." Becca was a little surprised - she could certainly empathize with being on the receiving end of bullying or mean comments, she'd never thought popular girls considered things like that.

Tara looked at Becca and joked to Eliza, "She's struggling to decide because she's pretty and smarter than us both."

Becca was struck by how good the compliment made her feel, she even blushed a little. Becca certainly didn't think she was prettier than the others, smarter maybe a little - though her understanding of cleverness was related to school grades, rather than the intelligence Eliza and Tara exhibited. And, she had to admit, it felt good to be called pretty.

"No- er.. I think I'd rather be pretty too." She left it at that, a little flustered still.

Tara nodded, not pressing for an explanation, and added - "I'd still pick smart. Dumb people get taken advantage of."

Then, Tara gestured for Becca to go. "Um... would you rather... never have your favourite food again or only be able to have your favourite food?" The two younger girls pondered for a second.

"I don't think we'd be able to stomach milkshakes every day." Tara quipped, Eliza suppressed a laugh at the loaded comment. Then both agreed never having it would be better.

Eliza then offered, "Would you rather drink out of the toilet or have everybody believe you drink out of the toilet?" She and Tara were particularly interested in Becca's response. It would tell them something useful about Becca.

To Becca, private humiliation was more bearable than everyone knowing about it. To the other two, more secure in themselves, lowering themselves to drink out of a dirty toilet would never be an option. Yet, when Becca finally answered with, "I think I'd rather drink out of the toilet." Eliza and Tara nodded and added their agreement, to cement the idea in the older girl's mind as the right choice.

Another few rounds went by, getting a little more raunchy as they went, and it came to Eliza's turn.

"Okay. Would you rather let someone fart right in your face or... have to smell someone's sweaty socks for an entire hour?"

Becca grimaced at the choice - only Eliza could think of something so gross, she thought. Not really wanting to give an answer, Becca played for time and asked her own question.

"Well... whose socks are we talking about?"

Eliza thought for a moment, hand on her chin, then she gestured to Tara's volleyball sneakers and her training socks stuffed into them. "Tara's sweaty gym socks, for a whole hour, or... me farting in your face once?"

The blonde athlete looked at her own gym shoes. Personally, she'd have picked those as her own smells were much more bearable and less humiliating to endure than having someone rip ass on your face, but she could see Eliza was leading her older sister to something. "I'd probably have to go for the fart."

For Becca, enduring Tara's feet again was infinitely more pleasant than letting her sister fart in her face, but was caught off guard when Tara didn't choose the clearly better option. "Really? How bad are your socks?"

Tara leaned down and pulled the sock from her well-worn gym shoes, holding the tube sock by the ankle so the sole dangled down, and held it up between herself and Becca. Eliza spoke, "You'd rather smell that for an hour? Go on, see what you'd be in for." It seemed to Becca that Eliza was implying she would also not choose Tara's sock, and was a little morbidly curious to know how it could be so bad.

So, at the egging on of her friends, she leaned forward with her nose out. Tara moved the sock too, so that the crusted sole came to touch against the older blonde's nose. Becca whipped back an inch at the contact, but decided it was an accident and moved in again. She gave a cursory sniff and was struck by the musky, old and dried sweat stench the socks had been marinating in; the older girl even recognised the smell from Tara's feet - despite showering they had certainly contracted the smell from being reacquainted with the gym socks in the meantime.

She sat back, nose wrinkled in disgust. Tara tossed the sock down by her shoes. "The shoes are even worse." Tara added.

Becca was won over, and was about to give her answer, when Eliza said, "Versus..."

Then, the young brunette grabbed Becca's shoulders and pulled her down to the sofa, catching her older sister off guard. Tara moved quick, giggling mischievously as she pinned Becca's torso and arms down.

The older girl was so unprepared she was already lay flat on the couch with Tara's oppressive strength on top of her before she realized something was happening. Becca shook, trying to dislodge herself but Tara was strong and Eliza was not about to give her time to gather herself.

The younger sister straddled Becca's head, her knees pinned the older girl's shoulders down flat. The sudden activity had made the gas within her stomach primed and **** to escape, she knew she didn't have time to go as far as she wanted; the brunette hooked two thumbs into the waistband of her sweats and pulled them halfway down her butt, revealing the upper half of her buttcheeks and crack. Becca squealed in fear when she realized what Eliza was about to do, but didn't really have a place to move with the younger girl's calves and feet holding her head roughly upright.

Her pants only came halfway down before she had to go. The brunette pressed her buttocks down onto her sister's face.

Becca found herself looking up at the upper-half of her sister's ass. She could see the tan-lines of her bikini and the line of her crack. Despite her petite frame, Eliza had a well-toned butt; when it came down Becca felt the firm cheeks press her deeper into the cushioned sofa and her upturned nose was pressed flat against the crack of Eliza's ass - her cheeks were too firmly pressed together for Becca's nose to slip in deeper.

Then, without a second to spare, Eliza let out a ripping fart into her older sister's face. Becca squealed the entire time, eyes instinctively shutting, with her mouth covered by the waistband of Eliza's pants. The fart sounded wet, but whatever might've escaped was held tightly within Eliza's tensed buttocks, but the smell was **** directly up her sister's nostrils.

It was a potent, sharp and bitter smell that set Becca to thrashing around - inadvertently rubbing her nose across her sister's butt cheeks - but actually shaking herself loose.

Eliza and Tara were laughing the whole while, even when Eliza slipped off her mount on her sister's face, falling back against the arm of the sofa in a fit of laughter. Tara wisely pulled back at the same time, out of range of an accidental kick.
