Shortly after I turned 18 I installed Grindr to see what I could find. I named my account 'test account' just to see how many people were in my area without having any personal info on there. That same night, someone messages me asking what my name meant. I told him that it was just to test the waters and not really anything serious. He then recommends that we meet up, butterflies immediately entered my stomach. I still lived with my parents and told him so, but then he said that he'll pick me up and go somewhere private. My hands were shaking at the prospect and every part of me wanted to say no, but he managed to convince me anyway. I stood out in my driveway, shaking and shivering in fear and anticipation for him to show up. I see his headlights and I walk up to his car and hop in. He starts to rub his hand on my thigh and rubs against my cock. This was the first time another person had ever touched me there, and I started breathing heavily as he drove me to a secluded spot. The spot ended up being an empty church parking lot. Once we stopped, he pulled his pants down and let his cock flop out, and I stared in awe before reaching over and groping it. While I touched his, he pulled open my pants and started rubbing mine, before leaning down to suck it. My legs were twitching and jittering like crazy until he leaned back and gestured for me to suck him. I leaned down and let it sit in front of my face for a few seconds before I gave it a lick and then put the tip in my mouth. He was already dripping with salty pre that coated my tongue and I pushed my head down further till I started to gag. I started bobbing like I had seen in videos before, and I was enjoying it, until I noticed his hand squeezing my ass cheek and a finger slowly creeping towards my hole. I moaned over his cock as his finger pushed in, and that's when he pulled my head off of him and told me to get in the backseat. All he said was "hands and knees" and I knew immediately what to do. My heart was beating out of my chest and I jumped as I felt him spit on my hole and then rubbing cold lube against it. He lined his cock up and slowly pushed into me. It obviously hurt a bit at first, but, and after some moments it started to hurt less, and he began to move back and forth at a slow pace. After a couple of minutes he started moving quickly, pounding his thighs against mine, and then he grabbed my hair and said "call me daddy, bitch" and smacked my ass hard. Now, I've never really had a thing for calling people daddy, but at that moment it was just so hot that I started screaming daddy like it was my number 1 fetish. He continued pulling my hair to hold my head back, I reached down to stroke myself, but he smacked my hand away and said "You only cum when daddy makes you" and my dick throbbed harder than it ever had. A few minutes later, and he shot his load inside me, and then he started jerking me off himself till I shot my load onto his seats. After that, we cleaned up, and, and he dropped me back off at my house. We had a few more meetups after that with a couple other things that I never expected to turn me on, but that's a story for another time.
