He had turned 18 a few hours ago, had grabbed his mother's Porsche and now we were cruising through Schwabing. I sat next to him and also got dressed up for the day. Tight sweater that really showed off my boobs. I was proud of it, such boobs at 15! Tight jeans, and so we were on tour. I met him last night at the disco (as they said back then). At midnight, just in time for his 18th, he ate me in the backyard. I was pretty stoned and excited about his enormous cock. At 10 in the morning he picked me up from my shared apartment. My roommates were excited about the Porsche. I knew nothing about him except that I had fucked my heart out that night. But the family seemed to be doing well.

“Hey sweetie, don’t you want to give me a birthday present?” “How? Yesterday I didn't even know you existed. How should I prepare something?" "I have an idea..." he said. "And?" "You can give me a blowjob while I'm driving, that would be really cool!"

I've never done that before. I've never given a boy a blowjob and in the car...?" But I also thought that the idea is really cool.

I slid down a little in my seat and leaned over to the driver's side. He had pushed the driver's seat back a little so that I could reach his lap more easily. With some effort I unzipped his fly and pulled his cock out. Wow, I now saw with my own eyes what I only felt last night in my pussy. I was lying not too uncomfortably and immediately took his part into my mouth and worked it with my lips and tongue. His dick became increasingly stiff and seemed larger and larger to me.

I hadn't even thought about whether you could see form the outside what we were doing here. I guess that you could already see the ups and downs of my head from outside. He moaned with pleasure. “You’re great Erika, awesome.” Suddenly he slowed the car down and stopped. "A traffic light! There is a bus next to us. Hold still for a moment!” I kept my head still and just let my tongue play. Fortunately, the Porsche is a fairly low car and from the bus you certainly couldn't look into it or see what I was doing.

He drove off again and I increased my activity again. Another traffic light, same game. He must have found the interruptions at the traffic lights cool, his erection was now harder than I had ever experienced one.

As we continued driving again, he moaned harder and harder and he twitched his butt and his penis. He grabbed my head with his left hand and pushed me into his lap. He rammed his penis deep into my throat. I wanted to say something, but I could only manage a gurgle. He twitched violently, his penis poked hard into my throat and then my stomach turned. At that moment he ejaculated hard and massive, really a lot. That was too much for Erika! I panicked, pulled myself away, and sat up.

I coughed as much as I could and spit out whatever was blocking my throat. A mixture of saliva, semen and vomit was spread across his clothes, the windshield, the dashboard and the rest of the interior. “You old bitch” he shrieked. The rest of the sauce dripped onto my breasts and messed up my sweater.

He stopped abruptly on the side of the street and I jumped out of the car. I looked down at myself, in my panic I had peed myself. The piss ran down my thighs and stained my jeans dark. The passenger seat had a wet spot. He screamed from the car, “You old pig, you bitch…” He closed the passenger door with a bang and accelerated.

There I stood. Covered in sperm and vomit and pissed on. The passers-by around me gaped and grinned. The situation was easy to understand.

What an old fuck, just get out of there. Hopefully his mom will spank his bottom and let him lick the interior of her beloved Porsche clean. You dumbass! Or your mommy will show you straight away how to get a blowjob and tell the cutest 15-year-old girl in town that you are going to shoot the full force down her throat, before you do.
