This is a tale from a time my friends and I (F22) took a road trip to a local quarry to swim and cliff jump. This takes place with my partner, Mitchell (M22), and four of our friends. We're take our car but because of limited room I have to sit on Mitchell's lap. This isn't an unnatural phenomena as I love to sit on my guys lap and will any chance I get. Even when we weren't officially together I loved teasing him by sitting on his lap in a completely "friendly" way. What can I say? I'm a girl that melts under physical touch. I just love being able to sense my partner through the warmth of our skin. It turns me on so much to know I'm the first one to much my boy in this way. I'm getting wet just thinking about it!

We're about an hour into the ride laughing and singing, when we hit a rough gravel road. As I'm staring out of the window, I'm instantly surprised by how good I feel. My brain puts two and two together and realize it's from my boys hard cock growing underneath me, giving me something to grind against. I know I can't really give him any type of menacing look because our friends will automatically wonder what's up. Not to mention, I have such a bad poker face. So I just let it happen.

All I'm wearing underneath my sun dress is a tiny swimsuit thong and tiny bra. A swimsuit Mitchell picked out with nudity in all the right places. All of a sudden, he grabs my waist and helps me covertly grind against him. He gets really excited really fast. I can feel him speed up as I slow down. I grab his arm hard, digging my nails into him signaling that it feels way too good to be doing right next to his friend in the backseat.

I feel a bit or warmth and wetness drip through my panties. I'm slowly starting the get a good, soft, and subtle rhythm with my hips helping my clit fill with blood and start to throb. Fuck. We're here. I'm completely at the mercy of this man's cock at this point and I just have to get up and go? My wet spot has significantly increased so I quickly run out of the car and jump into the river. One after another everyone joins me, excited about my enthusiasm and completely clueless as to why I slipped in the water so fast. I'm still so horny and want a cock inside of me, stat.

We are all having fun climbing on the rocks and laying in the fast river, but I can't keep my mind off of what was just happening. I'm laying in the shallows while climbing with my hands downstream, when suddenly I notice another pleasurable sensation. I look back to see that the river is fast and shallow enough that the water is quickly falling off the rock behind me creating a small waterfall directly onto my clit. This direct stimulation is too much for my horny body, so I keep laying there. I back up a bit to please myself with this waterfall making it look like I found a cool rock and am inspecting it further. Just then, I spy my guy heading towards me with a semi hard cock trying to escape his swimsuit. I completely lose control and let this river fuck my clit and cum relentlessly. He sees it all and his cock grows even more. I decide I'll make him wait to finish just like I had to do.
