Go back and read parts 1 and 2 if you need any details I leave out here.

The day following our 2nd hookup was as boring as the one prior. We played it cool and no one had any idea what was happening. That night we hooked up again, but kept it quick with making out, fingering, and a quick blowjob until I came in Dana's mouth. The following day however, things kicked up a notch.

In the afternoon we were getting ready to have a BBQ. Mike was prepping things to grill, Allie was working on some other dishes for sides, and the kids were playing outside. At one point Mike or Allie (I forget who) said we needed ice and a few other things from the store. Dana jumped up to get her keys and turned to me.

"Let's go. I'm not carrying ice and all that heavy shit." a comment that made both of our unassuming spouses laugh.

I followed her out the door trying to hide my smile because I knew I wasn't just getting groceries but also about to get my balls completely drained. Dana drove in her and Mike's big SUV (think Escalade or Suburban sized) and headed a few miles down the road, but pulled off down a dirt side road about a mile short of the small downtown area we were headed toward. Without a word she turned off the car and hopped out with me obediently following without question. She lifted the tailgate and we both climbed into the back and I quickly shut the hatch behind us. We immediately pounced on each other. After three hookups where we had to be semi-cautious, we were finally in a spot where we were truly alone and could just let it fly. We were pawing at each other like a couple of high schoolers and I couldn't remember the last time I was this turned on.

Soon we were both fully naked and Dana was sprawled out in front of me. I finally got to see her body in all its glory in full daylight. She was really way hotter than I ever gave her credit for, I shook myself out of it and got back to business. I dove in to eat her pussy for a bit and was pleasantly surprised at how vocal she was now that we didn't have to hide. She was gripping my hair and screaming my name, telling me how I ate her pussy better than Mike ever did. Every time she mentioned Mike it made my cock throb because of how taboo the whole situation was. After a few minutes I kneeled and gently pulled Dana's head up toward my cock.

"Fuck my mouth." She said with a devilish little grin.

I was stunned by the statement, and doubted how much she meant it. I went slow and stroked my cock slowly in and out of her mouth a few times before she pushed me back.

"What did I say? I said fuck it. Mike never gets rough with me and that's all I want. I have to beg him for it and the best he'll do is spank my ass a few times. Please just do it." she said with an almost pleading tone to her voice.

"Say no more, but be careful what you wish for." I thought to myself.

I gripped Dana's long, dark hair into a ponytail and held her firmly in place while I started fucking her mouth faster and faster. Drool was flying out each time I withdrew my cock and she gasped and smiled every time I gave her a slight break. I thrust deeper and deeper and even managed to get balls deep a couple of times. She gagged and retched when I was balls deep, but that just turned me on even more. Finally I decided she'd had enough and I need to fuck her again. I flipped her to all fours, gripped her hair again, and pressed her face down into the floor while gripping her hip with my other hand.

I slipped in and out of her slowly a few times and nearly lost it right then when I saw how tight her pussy was gripping onto my cock every time I pulled out. I picked up the pace and soon was fucking her as hard as possible, slapping against her ass loudly with each thrust and gave her a mix of every aggressive move I thought she'd like. I spanked her ass hard, leaving red handprints all over. I gripped her throat and choked her until her eyes watered, which shockingly made her smile and turned me on even more. I pulled her hair and pinched her nipples which just made her squeal with delight and beg me for more. I felt her start to convulse under me and her legs shook with a really intense orgasm. As soon as I was sure she was done I pulled out and pulled her face back toward my cock again, but this time I unloaded every last drop onto her face, something my wife basically never let me do. Dana took it all with the biggest smile I'd ever seen.

We collapsed in each others arms for just a minute to catch our breath. Dana wiped her face with some paper towels and wet wipes she had laying around in the truck and then we got dressed with impossibly wide grins on both of our faces. We made our trip to the grocery store as fast as possible so that no one questioned or noticed our little 15 minute detour.

Obviously that wasn't the last time, so part 4 is available if anyone wants it.
