Borrowed shorts and rearranged seats.

"Oh, fuck off..." I say to myself as I see what's waiting for me. Left on the pillow of the bed I'd been sleeping in is a familiar piece of gray fabric; the short shorts Amy had been wearing just a few minutes ago. A mix of feelings goes through me as I hold up the unfortunately scant set of shorts: angry that I'm being messed with like this, for one thing. Holding the plain pants over myself for comparison, I can see that these are just barely going to fit. The tip of my cock comes to the hem of the leg holes, and that's with me soft. Forget pitching a tent; if I got hard wearing these I'd be poking out for sure! But what choice do I have? None of my own clothes, the bedding would have to stay at the motel, the only towel still here was even worse than this; with a deep sigh, I step into them and pull them up. I'm lucky enough that the elastic is stretchy enough to stay around my waist easily enough, but that's about the only part of these shorts that isn't ill-fitting. Expecting someone with more to the back and the sides, the shorts are uncomfortably drafty up the legs, but up front I doubt someone half my size wound find these comfortable to wear. I take a few steps around the room, and already I'm having to adjust myself to keep my junk in the middle of these things instead of escaping alongside one of my thighs, and even that's less than perfect, leaving an obscene bulge that's only more noticeable for the way it clings to my still damp skin, the small towel left to me all but drenched before I was halfway done.

"Christ," I mutter, checking a glimpse of myself in the mirror on the dresser. I look ridiculous, and now I need to go outside for everyone else to see. I know it's this or nothing, with those girls out to get me, but that's a small comfort as, with a shudder, I open the door and step outside, letting it click shut behind me, the keys long since returned to the desk.

Snrrrk

And already the ridicule starts; I look to my left and the blond housekeeper is staring at me wide-eyed, a grin poorly hidden behind her hand, and her cart parked between me and the stairs down.

"'Scuse me," I say quietly, as I shuffle past her, squeezing between the cart and the balcony railing, blinking as my eyes adjust rapidly to the bright mid-morning Sun. Looking back she isn't even pretending not to gawk at me, and I hurry my pace until I get to the stairs; I have to stop midway and readjust myself as trying to run downstairs was starting to jostle my junk out of the shorts. I hear more giggling, and see a couple of older ladies sunning by the pool, brunch mimosas in hand, and the pale parts of their tan-lined skin not yet quite as red as my face is. I turn the side of the building to find our car, where I know at least now I can get out of sight, relatively safe from the car's other inhabitants in the passenger seat, and open the front-right door with a sigh of relief....

"Woah-hoh, bro! Really letting it all hang out this vacation, huh?"

The blue hair and glinting eyes of my step-sister Jessica is what greets me, reclining in the passenger seat with her phone in her hands. Past her I can see the blond hair and equally amused expression of her twin Sarah, as I stand there flabbergasted.

"Wh- Jessica! Why are you in my seat? Where's Mom?" Jessica just hooks a thumb to point to the back of the car, and through the open window I can see my step-mom, in the very back row of the car, sleep-mask on while she fans herself with a paper roadmap. Sitting in the same row as her was Emma, already probably not feeling so comfortable next to her hungover host, but not even trying to look me in the eyes as I catch sight of her.

"Yeah, so, Mom got a little tipsy last night," Jessica says, "and she needs to cool off a little before she's in any shape to drive. Lucky she's got two kids with their licenses, right?" I roll my eyes; the fact that they had their licenses while I still only had a permit was just another point of pettiness between the three of us, but in this case it was just compounding then problem I was already stuck with!

"Well, where am I supposed to sit then?" Jessica grins, and just nods her head backwards again. I pause a moment, before wincing and opening the back right door, finding myself face to face with Amy. I was right about her bikini bottoms; without her shorts, I can see the pink straps hanging tight to her hips are holding up a small, triangle shaped piece of fabric in the same color, and the back is bound to be just as small. Further down, I don't see Nat yet, but her bag is in the window seat on the other side, unofficially calling 'dibs', leaving only the seat in the middle unoccupied.

"Oh, good, you found them!" Amy says, patting the seat next to her. "Come on, we can still get to the park in time if traffic is good!"

"...Do you want to step out first?" I ask.

"Nope!" I frown, and look through the window; the jackass who parked next to us is all but in our spot, keeping the door on that side firmly closed for fear of hitting them. Shooting her a dirty look, I climb into the seat and awkwardly pass over Amy. As I do, Jessica suddenly moves her seat back, and I all but fall into Amy's lap, who doesn't waste any time 'catching' me with both hands on my ass. "Careful, George!" she says with a squeeze.

"S-sorry! Sorry," I say, coughing to hide a voice crack. I want to pull away quickly but I feel resistance; Amy's pinching hem of the short's leg-holes, and I while I catch myself before anything shifts too far out of place, I can feel the elastic stopping just above my shaft. Amy giggles a bit more, and I quickly sit down, with a deep breath.

"'Scuse me," I hear, and turn to see Nat making the same trip I was. Weirdly, she somehow doesn't get 'accidentally' shoved back or groped, but as she passes by me, she takes extra care to move carefully, leaning over to balance herself on the front seats, her legs on either side of mine, and her ass sticking straight towards me, as I lean back and sink back into my seat as much as I can to avoid contact. Two big, brown cheeks separated by a thin strip of denim take up just about my entire field of vision, and I clasp my hands tight over my rising erection, still pent up and easily excited since my attempt to alleviate it was interrupted earlier. "Sorry," she says simply, eyes darting down to see her success in riling me up.

"So!" Sarah says, putting the car in drive as Nat moves her bag and sits down, "let's get back on the road!" Everyone else cheers or at least mutters their agreement, but I can't quite join in, knowing I'm sitting smack dab in the middle of this mobile lions den for at least another couple of hours.
