Justin's Faulty Family Vacation

Justin glanced over at the driver seat, taking note of his mother's relaxed, vacation-ready look. There was a faint smile on her face--And he tried to keep his eyes on that, rather than the huge expanse of cleavage that was bursting out of her flower-print dress.

Kelly was a curvy woman, and her son was far from oblivious to it. But Justin was no pervert--Or he tried not to be, anyway--So her voluptuous body was a bit of a problem for him. She was dressed for the weather where they were going, too, resulting in far fewer bulky layers than any of her usual outfits. The 50-year-old brunette was usually quite modest, especially since the of her second husband a few years earlier--But a beach resort in Thailand didn't call for wooly sweaters!

In just a few hours, she'll be in a bikini, Justin thought, before shaking away the thought. More importantly, she'll be happy. We're ALL gonna be happy... And all because of me!

After a lifetime of treading water, the 28-year-old freelance programmer had finally got a win. One of the apps he was helping with hit it big, and luckily he'd taken a royalty deal as payment for his work.

When he showed the check to his family, they were floored. Justin had a long history of minor screw-ups: arriving late to work, making tiny mistakes on important projects, and other issues that would be forgivable on their own but stacked up quickly. It didn't make for a promising career.

Finally, I can be the son she deserves--And the brother THEY deserve, Justin thought, glancing at the back seat. His twin half-sisters, Shelby and Ava, were both looking at their phones and chatting excitedly.

The 19-year-olds were both beyond excited for the trip. Lockdowns and social distancing had ruined their last few chances at wild Spring Break trips, and now they were looking to catch up before starting college.

As Justin watched, Shelby poked Ava and showed her a picture of a sunlit beach near where they'd be staying. Ava let out a squeal, shimmying her huge ass from side to side and biting her lip. "Ohmigod--It's so romantic!"

The girls were both much skinnier than their mother, and blonde instead of brunette. They had her striking, pale-blue eyes, though, and certainly had her ass. Years of volleyball and squats gave them quite a bottom-heavy silhouette--Another obstacle for Justin to navigate in his efforts to not perv out on his own family.

To make matters worse, both sisters had several tattoos, and most of them were in inconvenient places. Hearts on the bottom of their butt cheeks, which frequently peeked out of the thong bikinis and booty shorts they preferred. Their names written in cursive, just below their small-yet-perky breasts, which also saw plenty of exposure in their skimpy outfits. The infinity symbol on both of their ankles was a little less provocative--But then again, Justin could appreciate a good pair of feet, too, especially when they were attached to a hot girl lounging in a bikini.

And when it came to Ava and Shelby, "lounging in a bikini" certainly seemed to happen a lot. The sisters were very active on social media, posting blatant thirst-traps on a daily basis. It always made Justin feel protective... And more than a little aroused.

On the day before their trip, he was scrolling through Shelby's Instagram and came across a pic of the girls sharing a comically-large hot dog. They each had a different end in their mouth, and were staring wide-eyed at the length stretching between them. It instantly got Justin rock-hard, and with growing discomfort he'd realized why: their exaggurated expressions looked just like the ones his favorite camgirls all used when they were face-to-face with a huge dick. Do my sisters do that, when they're about to... Gah!

But now, in the car on the way to the airport, he was thinking more wholesome thoughts... Proud that he could give his sisters a much-deserved vacation, after a rough couple of years. That he could finally step up, taking his late stepfather's place as man of the house.

They didn't even believe me when I told them about the app, he mused, relaxing back into his seat. The look on their faces when they saw that check... Guess they never thought I could be a provider--Or anything besides a screw-up. I showed them... This is the new me. The REAL me. Finally out from under the shadow of... Of that dickhead.

Justin's expression soured a little as he thought about his birth father. He'd left when his son was just a toddler, and they hadn't heard a word from him since. Justin grew up hearing everyone in his mother's family insult the man in hushed tones, and ever since his greatest fear was that he'd take after him.

My dad--No. My useless sperm-donor--He ran from this family. My stepdad fixed it... Gave Mom her confidence back, gave us Shelby and Ava... But now it's my job to take care of them. To treat them how they deserve to be treated.

He took one more look at the thicc MILF in the front seat, and the bottom-heavy teens in the back. A smile appeared on his face.

"We're almost there," Kelly said cheerfully, as they turned into the airport parking lot.

Nah, Justin thought. We've already made it.
