Before she had a chance to react, I jumped out of the car, leaving her alone with the horny driver. I walked alongside dad until we were on the other side of the truck, then said:"Hang on, forgot my camcorder... be right back."
I ran back to the car, opened mom's door -- the driver had already taken out his cock, figuring mom was game -- and grabbed what was left of her dress, tore it completely off of her and pushed her panties down to her knees so fast and so hard that they ripped at the seems, exposing her almost completely naked body to the horny, wanking driver.
Mom remained particularly calm... I grabbed the camcorder next to her and closed the car door, hurrying back to dad and walked alongside him to the shop. I lingered there for a few minutes, pretending to be looking for batteries - wondering what the driver was doing to mom or vice versa - while dad was browsing through some local sightseeing brochures.
I snuck out the shop and hurried back to the car, where mom had rolled down her window... I leaned in and saw the driver sitting on his knees on the back seat next to mom, who was playing with herself, one hand on her tits, the other between her legs, edging the lucky driver on to get off as quickly as possible. Which he did...
Propelling himself up and forward, he wanked off furiously and groaned, shooting long thick squirts of cum on mom's thighs, belly and tits. Seeing her get drenched like that was too much, so I took out my hard cock, rubbing it up and down.... not really sure what my next move was going to be. The driver got out of the car, looked at me and surprised me by asking:"You want also?"
"Yes, but my dad will be back soon." I replied.
He smiled and said:"I take care of it... you go, you go." as he pointed at the car invitingly and then hurried towards the shop, no doubt planning to keep my dad away from the car for another couple of minutes. I didn't hesitate and stuck my hard cock in through the window, jerking off furiously, longing for another release. Mom looked at me, while rubbing the driver's cum into her skin and said, glancing at my cock:"So, this is what you've reduced me to... just a whore for men to dump their cum on, one after another?"
"Fuck yeah! Stick your face out of the window, slut!" I grunted.
Mom leaned out the window and turned her face upwards at me, presenting it to me, my cock now inches above her head...
I kept wanking and she kept playing with herself, until I too blew my load... it wasn't a spectacular amount, but I dumped it right between her eyes where it formed a small glob and slid down into her left eye. Mom licked my sensitive head for a few seconds, then got out of the car and used what was left of her clothes to wipe off all the cum. She walked to the back of the cab, opened the trunk and took another summer dress out of her suitcase to replace the torn one; although replacement underwear was now also within her grasp, she closed the suitcase back up and slammed the trunk shut. While she was still freshening up a bit, the driver returned with dad in his wake. "Look at this, we've gotten free fajita's and soda's... the cab driver and the guy running this gas station are cousins, wouldn't you know it!" dad said. "You all eat and drink here... I wait, no extra charge." the driver smiled. When dad asked me about the batteries, I said they didn't have the right ones and that I would get some later.
Mom, dad and I leaned against the trunk as we ate and drank our free gifts, while we struck up a conversation with the driver about Spanish life in general and being a cab driver in particular. Dad, not a great talker but a fast eater, was finished first and said:"Gotta take a leak..." and walked towards a nearby tree. While the driver continued talking about something uninteresting that had happened to him on one of his rides, I reached under mom's dress, tickling her moist cunt, shocking the driver. Mom looked at me while she continued eating her fajita, the driver quickly lost interest in his own story and just stared at us. When I heard dad coming back, I redrew my hand. Unnecessarily as it turned out, because he stopped to browse through his bag pack on the passenger seat, took out a map and folded it open on the hood of the cab, studying it carefully. Realizing dad wasn't coming back in the next couple of minutes, I signaled the driver to come closer and took his hand, putting it under mom's dress. As she put the last piece of fajita in her mouth, she opened her legs wider, offering him better access!
I couldn't believe what a complete slut she had become! In his wild arousal, the driver immediately tried to shove two fingers up mom's cunt, which caused her to wince and pull back...
"Easy Zorro!" she whispered, as she took his hand and pulled one leg up onto the bumper, than lined up his fingers with her entrance and said:"Tranquillo, okay?"
The driver couldn't believe his luck as he nodded like a fool, entering her very slowly -- it was obvious that it required all of his restraint not to shove his whole hand in. Once he was sufficiently deep inside of her, mom relaxed a little more and opened her soda, taking a sip as the cab driver slowly finger fucked her...
Granting them some privacy, I walked over to dad and asked:"So, have you figured out where we are yet?"
As I was keeping him focused on his maps and brochures, I glanced at mom and the driver as much as I could... while he continued to finger fuck her, mom casually sipped from her soda with one hand and unzipped his trousers with the other, taking out his tanned dick, playing with it, getting it nice and hard. A few minutes later, I saw mom squatting down, taking the driver's cock in her mouth, sucking on it! While she was her knees, the driver opened up the trunk, obstructing the both of them from my and dad's line of sight. Although shielded from us and the rest of the parking lot, any car passing by on the road had a clear view of mom going down on our cab driver... several cars even slowed down or honked their horns as they passed by. I was curious about what nasty stuff mom was up to now, so over the next couple of minutes I slowly backed away from the car, while keeping the conversation with dad going, until I once again had a clear line of sight on mom and the cab driver.
Mom was bent over completely, her hands around her ankles and the driver had sunk his cock in her cunt, shafting her slow but deep... my cock nearly burst through my shorts as I saw her in this enormously slutty and submissive pose. When another car passing by honked and the occupants waved and cheered, dad looked up for a second and waved back, oblivious to the fact that they were cheering for the cab driver fucking the shit of his whore of a wife... I quickly diverted dad back to his maps and brochures with some stupid questions while I continued to glance over at mom every chance I got, gradually moving towards the mid-section of the cab. From there, I had a perfect view on dad as well as on his cheating wife, bent over like a whore taking it up her cunt from this perfect stranger, who's name we didn't even knew.
Mom seemed to have very little reservations about her behavior; as a matter of fact, the sluttier she behaved the more she seemed to be enjoying herself... I couldn't believe how horny I was, just looking at her getting pounded by our cab driver, not five meters away from dad, separated by nothing more than the trunk. Suddenly the driver grunted and moaned something in Spanish, pulled his cock out of mom's cunt and blew his load all over the small of her back. Heavily panting the driver pulled his pants back up as mom stood up straight and pulled down her dress, trying to look respectable again. The driver walked past me, winked and then started talking to dad, switching places with me as I walked up to mom...
"You fucking slut!" I whispered, smiling at her.
Mom looked at me, ran her hands through her hair and said:"Like this isn't exactly how you want me to be!"
I smiled and replied:"Damn right, so... do I get another turn?"
Mom:"Sure, if you don't mind the mess..." as she bent down again, lifting her skirt off her cum-covered ass and grabbing her ankles.
"Jeez mom!" I whispered as I couldn't believe what a whore I had created. I quickly unzipped and grabbed her ass with both hands, slipping my cock into her willing cunt. She was so loose that my cock nearly fell into her hole. After just a few thrusts and not even twenty seconds, I got off for like the millionth time that day and shuddered, pulling back and shooting what little cum was left in my balls on her ass. We got dressed again and slowly walked towards the front of the car where the four of us talked for another couple of minutes, before packing up and resuming our cab ride to the apartment complex.

Part II: Getting to know the neighbors
The rest of the cab ride took a little over an hour. Our apartment was a time share in a plain apartment complex, it seemed as if we were the only tourists in the entire building. On our way in, mom got a lot of dirty looks from the local men and I could see her getting frisky as she started to sway her hips, sexing it up a little more. We were on the fifth floor of an eighteen story building, in a corner apartment with a lovely view of the local bay area; we started unpacking and after about half an hour dad announced that he was going to take a nap. Once he was on the bed resting, I snuck up on mom and reached under her dress, immediately finding her pleasure button to play with!
