Sat on my guy friend's lap during a trip, and he got hard, which made me wet. [FM]

Okay, so I'm 19, in my second year of college, and last week we had this class trip for some dumb bio field study. I'm still freaking out about what happened, so I gotta share lol. Sry for any typos, I'm writing this fast before class.

So we're on this packed bus, like 30 of us crammed in, heading to some forest for the day. I'm in my fave tight jeans and a tank top, feeling cute but not trying too hard. The bus is full, so I end up sitting on just a collage guy friend oh mine his lap (he's 20, kinda nerdy but hot, like glasses and muscles vibe). I'm squirming to get comfy, and like 10 minutes in, I feel it—his dick getting hard under my ass. It's pressing right against my pussy through my jeans, and ngl, I'm instantly wet. Like, soaking through my panties wet.

I glance back, and he's all red, trying to play it cool, but I can tell he's dying. I'm such a tease, so I grind my ass a little, real subtle, and he lets out this quiet groan. It's so hot, knowing we're surrounded by people who have no clue. I whisper, "You okay down there?" and he's like, "Fuck, you're killing me." That's when I know shit's about to go down.

After we arrive at the camp at school, we immediately get to the forest, and while everyone's packing out and getting to their roomss, we sneak behind this big tree further ahead behind the tiny houses. He grabs my waist, pushes me against the bark, and we're making out like crazy. His hands are all over my ass, squeezing hard, and I'm grinding my pussy against his dick, still hard as fuck in his pants. I yank his zipper down, and his cock springs out, thick and throbbing. I drop to my knees, spit on it, and start sucking, deep and sloppy, gagging a bit while he's moaning, "Fuck, you're so good." The risk of getting caught makes my pussy drip even more.

He pulls me up, spins me around, and yanks my jeans down just enough. I'm bent over, ass out, and he slides his dick into my pussy, slow at first, then pounding me so hard the tree's shaking. I'm biting my lip to keep quiet, but I'm so wet it's loud, like, sloppy sounds echoing. He grabs my tits under my shirt, pinching my nipples, and I cum so hard my legs shake, pussy clenching around his dick. He's grunting, calling me his "dirty little slut," and I'm loving it. He keeps giving me hard backshottsss while I grind my ass on his cockk. He moanss he is about to cum and all off the sudden he just cums in my pussy I feel his cock pulsating in my wet cunt it was so hot. And at the same time I was worried he just came ate my pussy. After we head back to help the rest and for the coming to weeks fucked somee more...
