A Water Park Vacation

It's the summer right after senior year of high school. Just after graduation, I hear word that my dad, who travels a lot for work and is rarely not absent from my life ever since mom died, has gotten a big promotion to executive board member. As a bonus for the promotion, he's also received a paid vacation for him and his family over the summer. Excited to finally have some free time to spend with the family he's **** to neglect to keep us fed, we all prepare to head down to Florida for a water park resort vacation.

My dad is the biological one. After my own mom died, he remarried about ten years later. My step-mom is a large woman. Definitely getting on in years, with wrinkles showing on her face when she smiles (which is often), but I can see that some people might like her for that thick MILF appeal with her rubenesque figure and C-cup breasts, though I personally don't find her all that sexually appealing. She's kind of... ditzy, to put it diplomatically. A natural blonde, at that, with her hair cut short and kinda spiky to show her hoop earrings. She's about 5'8", same height as me.

Her own daughters are my step-sisters, Sarah and Jessica. They're identical twins, pale-skinned blondes like their mom but Jessica dyes her's blue for some reason. Probably to differentiate them. They're both slender with D-cups, and hair down to their shoulders. They're both 5'10", just under my own 5'8". Personally I don't get along with them that well. They seem to like teasing and embarrassing me a lot.

The vacation deal allows dad to invite three guests and he gave me the choice. So I called up Amy. She's a classmate of mine from high school, lives only a few blocks away, and I'm secretly harboring a pretty long-time crush on her. She's a hot redhead with hair down to her shoulders, a curvy and leggy body that stands 5'4", and a sweet pair of DD tits. We're kinda almost friends... She certainly acts familiar with me and she's come over to my house a few times. She's sexy and she definitely knows it. I rarely see her without a lot of skin on display and I swear I've seen her stretching and bending over to intentionally put herself on display. Probably just wishful thinking on my part. I told her she could invite two of her own friends. She chose Natasha and Emma.

Natasha is Amy's best friend. Black and of Russian ancestry, she got a trim, athletic body from running and gymnastics. Natasha has raven locks down to her shoulders and I don't think I've ever seen her wear a bra for her perky B-cup tits. I usually never see her unless she's with Amy, but each time we've met, she's been pretty snarky and sharp-tongued. I don't mind, though, since she's got a sweet ass. She's 5'6".

Emma I don't know that well. Supposedly she's a friend of Amy's, but I've only rarely seen her hanging out with her at lunch, and Natasha barely knows her. I think she lives farther away from the school and on the other side of town from them and I don't know how such an outgoing girl befriended such a shy girl. I think it was one of those extroverts adopting introverts deals. Emma is short, I think about 5'0" tall and a bit on the plump side from what I can tell from her thick sweatshirts, hoodies, and modest skirts. With her square, thick-framed, black glasses, she definitely looks geekier than her more glamorous friends. But she's a natural blue-eyed blonde with messy cornflower hair down to the small of her back and a smattering of freckles across her cheeks and nose. I can't tell but she looks like she's got surprising volume in the chest of her thick clothes.

I was all excited for this trip when disaster struck just the day before we were leaving. My dad had a nasty accident at the hardware store. The receptionist of the nearby clinic, a pretty blonde in her mid-20s, told me dad would need to be in bed healing up for a few weeks there. Unfortunately, the trip couldn't wait, and dad said to go on without him.

And that's how I wound up in this situation. Riding shot gun in an SUV as the only guy on vacation with six girls! I'm not exactly a confident guy. I can barely talk to Amy and my step-sisters tend to have me wrapped around their fingers. The pit of nervous dread in my stomach is an omen, I can tell. I hope the vacation will be pleasant, relaxing, and fun, but... I always like to assume the worst. That way there's always a chance I'll be pleasantly surprised.
