Between two jocks in a hard way.

As I start down the center of the bus, I keep my backpack held tight in front of my crotch for fear of losing it; a good idea, it turns out, because it doesn't take long for the hushed giggles and camera clicks to grow into something a little more daring.

"Hey! Where're you going?" I flinch as I feel a light swat to my bare ass, and walk a little faster. The next thing I know, the other emboldened girls start reaching out at me as I pass, either to grope or spank me as I walk past, or to try and smack or snag the one item of cover out of my hands. I focus so much on moving forward past them that one hand manages to blindside me; not to steal my backpack, thankfully, but to pull me into their seat entirely! I keep my balance enough that I can maneuver my fall to just sit down in the middle of this three-seater, but looking at the two girls on either side of me I can't help but feel my stomach sink even further.

It's no surprise that they managed to pull me into the seat; Sam and Tiffany are two of the swim teams top performers, and they can outrun and out-muscle just about anyone in school, of whatever gender. Sam is the taller and more slender of the two, dressed in a hoodie bearing our schools logo and a pair of yoga pants. Tiffany was a bit shorter and curvier, but she moved just as fast in the water and, as I could feel from her hand around my arm, just as strong. I didn't know Tiffany very well, but Sam and I used to hang out in middle school, though we'd drifted apart since then. Apparently she was looking to reconnect for some reason...

"Oh my God, George," Sam starts, incredulous and joyful all at once, "what the hell are you doing?"

"It wasn't exactly my idea," I say, "I don't really want to talk about it...." Trying to dodge any further questions, I open my bookbag and see, as promised, a balled up pair of socks and my regular pair of sneakers. At least, I thought, I could rely on them for that much. "Um, do you mind?" I say to Tiffany, and tug my arm loose as I pull the footwear from my bag.

"Not at all!" she says, and from the way she's eyeing my legs, I don't think she's talking about the same thing I am. Still, if I can't cover anything important, I can at least make walking around a little more bearable. Making sure to keep my bag firmly between my legs, I slip on the socks and shoes, and it's the moment of relief I have afterwards that costs me. See, in the second I let my guard down, leaning back up straight, I feel an arm slip under mine from either side. I'm suddenly shoulder to shoulder with Sam and Tiffany, and their superior strength is keeping my arms locked tight at my sides.

"H-Hey!"

"Hm? What's the matter?" Sam says, placing her hand on my thigh. Immediately I clamp my legs together, backpack in my lap, but the girls are as strong in their lower limbs as they are up above, and they each hook their legs around mine, pulling them apart. My backpack is still resting in place, hiding my cock, but every bump of the bus threatens to jostle it out of place. I give up struggling, lest I knock it over myself.

"Let me go!" I say instead, trying to keep myself quiet so that I don't draw too much more attention.

"Aw, c'mon," Sam says, trailing her finger along the inside of my leg. This time, I can't do much to stop her, "you come to school naked and suddenly you're getting shy?"

"I-I told you! I don't want to be doing this!"

"Pff, yeah right!" Tiffany says. She leans into me further, placing a hand on my bare chest. "If we move that bag of yours, I bet we'll see just how much you're enjoying this, won't we?"

"N-no!" As distraught as I am, she isn't wrong. The rush of the exposure aside, the way the two of them are lightly brushing their hands against my thighs put my boner back on the rise. With a giggle, Sam starts to play it up; grabbing my wrist to switch which of her arms was holding me, she puts her now-free arm around my shoulder and pulls my head in closer to her chest. Tiffany follows suit, pulling my leg into position that she's now straddling it, and I can feel her thick thighs press together around it as she leans forward to give me a glimpse of cleavage.

As if my body wasn't already betraying me enough! The way the two girls are touching me is pushing me to my limit, and my hard cock is about to push it's only cover over so that anyone could see it! I try to press myself further back against my seat, any futile attempt to keep what little dignity I have left, but it's not to be. The bus hits a bump, and my backpack falls to the floor, sliding off somewhere towards the back of the bus. My erect cock is bared to both bullies; Sam just giggling even more, and Tiffany letting out an appreciative whistle under her breath as my now fully nine-inch penis is standing up in front of them. I hang my head, but when nothing happens I look back up, to catch the two girls sharing a devious smile.
