The TuneUp by Rev Lover

 Mark's mom came over one day and asked if I could work on her car. I was pretty familiar with it. She had owned it for years and they had lived across the street from me since I moved in. It was sharp old car, a '66 Chev Impala station wagon. It had a 327 V8 that ran great even though the mileage was 100,000 plus. She kept it clean and was proud of it. She even had a chrome tip on the tailpipe. She also had an aging glasspack muffler on it that sounded pretty good. A lot of days before I left for work I heard a tailpipe mildly rap over at the apartments. Most of the time it was Mark starting the wagon to warm it up for his mom. He was hooked on the sound of an engine and couldn't resist playing with the pedal. His mom wasn't much better. She actually made a louder rap come out of the tailpipe than Mark when she started it. She was one of those women that pushed the pedal a long ways down to start a car. There would be quite a rap and puff of blue smoke from her starting technique. She didn't have a problem with just plain rapping the tailpipe either at times. I had heard her make it sound sweet a few times.

She asked if I would check it out and do a tune up. It was running fine but she hadn't had it to a shop in a while and had learned a hard lesson about that when Mark was 8 years old. Mark had been hanging around since I bought the Ford LTD and he seemed, to her, to be interested in cars. (She had that right....Boy if she only knew.) She thought that if I worked on it Mark could help and learn. It sounded OK to me...I wasn't about to pass up a chance to "test the tune-up" and rap that chrome tipped tailpipe. Mark would surely be able to fill me in on the particulars of rapping the wagon, since he'd been doing it every time he got the chance.

Saturday morning the Impala and Mark were in my driveway at 9:00 AM. I knew by the VROOM VROOM of the tailpipe. I moved the LTD out and put the Chevy in the garage. It wasn't going to take too much time to check it out and figure out what parts to change, like spark plugs. I ran a check and figured we needed points, plugs, condenser, and wires. The plug wire were pretty hard and didn't want to bend. I mentioned to Mark that it couldn't have been running too great at full throttle or high rpms. He said it wasn't, that it missed and backfired quite a bit. I answered "like when you're out revving it and rapping the pipe". He shook his head yeah and grinned. I made a list and sent him down to the parts store in the LTD, while started taking plugs out. The LTD's pipes sounded pretty good as it left.

I had all of the plugs out and the distributor waiting by the time Mark made it back. I ran a compression check and all of the cylinders were fine. Mark got back in the middle of the compression check. It took about a half hour to put the plugs in, put the wires on and set the timing and dwell. I checked the rest of the mechanicals like the u-joints and jacked it up and looked at the brakes. The wagon was in fine shape and was given a clean bill of health. It time to take a spin and "test the tune-up.

We took off for the hinter lands. Mark already had a big bone and I had one on the way. The wagon drove straight and the steering was tight, although it felt like the shocks were a bit weak. When we got out in the country I slowed to a crawl on a long straight stretch and put it in low. Then I floored it. It took off damn nice for a big wagon with only 2bbl carb. That chrome tipped tailpipe sounded very sweet and was plenty loud with it revved up. I wound it tight and the old 327 really screamed. I was looking in the mirror and the exhaust was pretty clean. It turned blue when the engine was at full scream, but it wasn't too bad. I let off on the gas pedal and the tailpipe rapped like hell. Then it easy to tell the 327 had 100,000 plus miles on it. Thick blue/white smoke poured out of the rapping tailpipe and formed a swirling trail behind the car. I let it rap down to about 20 and took it up to a scream again and let off. The smoke poured out of the tailpipe again as the car slowed down of compression. I looked over at Mark, who was looking over his shoulder out the back window. He turned and said "Cool huh". I answered "Nice". We were coming up to same place where I had had Mark romp on the LTD.

We wheeled in and parked it. I opened the door and started revving it up to make the tailpipe rap. I was impressed. The aging glasspack wasn't really doing much at all. I had tapped on it when I was under the car and it rang. The glass was gone and all it was was a tube resonator. The old wagon really sounded good. The tailpipe wasn't as loud as a straight pipe, but it has the same sharp tone when the gas pedal was released with the rpms up. Every time the I let up and stepped down the tailpipe blew a big puff of blue smoke. In the 30 seconds that I'd been revving it and rapping the tailpipe, the wagon had already made a big cloud of blue smoke that was floating away across the field. No wonder Mark got a bone over revving up and loud tailpipes. His mom owned a regular "rap mobile". I told Mark that he'd probably really get off on seeing the pipe blow smoke while I revved and made it rap. He didn't need to be told twice.

Mark went around to the back and to the driver's side so that he could see the tailpipe. I started revving the engine in fast bursts to make the tailpipe rap and smoke as much as it could. Mark signaled a big OK with his hand and watched the show. He had a big bulge in his Levis. I played with the gas pedal and rapped the tailpipe for about 45 seconds and made a nice cloud of smoke. I stopped and got out and told him it was my turn. He got in and started revving it. He made the station wagon rap and shoot smoke out of its tailpipe just as well as I did. He obviously had been practicing. I listened to the roar and rap & watched Mark's smoke show. The smoke blowing out of the roaring tailpipe in powerful blasts looked inviting. I really wanted to feel the hot exhaust blow on my dick so I walked into the plume of smoke shooting from the tailpipe. I moved toward the tailpipe and the heat & smoke intensified. Then I got on my knees about 2 feet from the end of the tailpipe while continued to rev up.

I arched my back and thrust the lump in my pants out to meet the hot smoky exhaust blasts. It was an absolute rush. Each time Mark gassed it, the hot exhaust blew with force on my swollen dick. When he let up a big blue smoke puff hit my crotch and swirled around me. The exhaust stung my eyes a little, but it wasn't hard to breathe. My dick was getting super hot and it felt so good with the blasts hitting my dick, that I was about to lose my load in my pants. I got up and went up to the driver's door. Mark was already out of the car and heading for the back to assume the position.

I started rapping the tailpipe and blowing smoke at him. He arched his back to put his bulging crotch full to the blasting exhaust. It looked awesome to see him getting a hot smoke blow job. I was rapping the pipe at a steady rhythmic pace. The engine was revving up to over 3/4 and the tailpipe was making a WAAP sound every time the I punched the gas pedal. Mark reached down, dropped his pants and shorts and whipped out his enormous hardon. I kept the rhythmic revs going and he started stroking his shaft in time with my tailpipe blasts.

WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP powerful blasts of hot exhaust smoke slammed into his throbbing shaft. WAAP WAAP WAAP WAAP WAAP WAAP WAAP as he stroked his shaft in time to my pedal thrusts. He stoked and stroked in the blasting smoke until he started shooting cum. WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH I floored it and held it on the floor until he quit shooting a huge load.

A jet of gray and blue smoke blasted from the screaming tailpipe onto his spasming cock when I floored it. After several squirts of cum erupted from his cock he fell to his hands and knees panting and trying to catch his breath and let off the gas. I hoped he was OK. I realized that the jet of hot exhaust blasting his shaft when I screamed it could have burned him. He was light headed, but OK. Probably from the exhaust and cumming so hard. I asked if it had burned him. He said no, but that the heat had been great during the revving. He said when I floored it, the increased heat and blast sensation made the orgasm super powerful.

I needed to unload so bad my nuts ached. I asked Mark if he'd blow me with the tailpipe. He said he'd be disappointed if he didn't get to. I assumed the position with my pants down and shaft in hand. WAAP WAAP WAAP WAAP WAAP WAAP WAAP what a sensation as the hot exhaust pounded my crotch as I stroked to the time of Mark rapping the tailpipe. WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP the sensation was unbelievable as I stroked my shaft in the hot blasts from the tailpipe. WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP my shaft was getting hotter and hotter from the hot smoke hitting it as Mark floored the gas pedal. WAAP WAAP WAAP WAAP WAAP WAAP WAAP WAAP until I couldn't keep my cum from shooting. Mark saw it and held the pedal to the floor and made the tailpipe scream and blow smoke all over me.

WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH the engine revved to the max until I stopped shooting my hot cum. I couldn't believe how it felt when the hot exhaust blasts were hitting my dick as I stroked it and Mark rapped the tailpipe. But, the feeling of my cum shooting with the tailpipe screaming and its jet of hot smoky exhaust blasting my dick was even better. I had to rest on my hands an knees too.

We got back in the wagon and looked at each other. What an experience. I asked Mark if this was his first experience with blowing exhaust on his dick. He answered no. He said he had cum before with his dick up to the puffing tailpipe. I said that I had shot many loads on and in a puffing tailpipe. I said this was the first time I had ever had my dick blasted by hot exhaust, however. Mark said it was his first time getting blasted too.

Then I noticed how bad we smelled of exhaust. I looked over and Mark's crotch had a dark carbon stain from rapping the tailpipe on him with his pants up. I looked and so did mine. How in the hell were we going to deal with this problem. The exhaust smell could be passed off as that we ran the car in my garage working on it. The garage filled with exhaust and we kept working. But, we finally had to give up and put the wagon outside. The black blast patch on his crotch was going to take another tactic. We never came up with much of one, so we went with the "must of spilled something on his pants path".

I hoped to hell his mom bought it.
