"Aloha!" Sarah my sister waved good-bye to our parents who were on their way on vacation in Hawaii.
"We'll see in you in a couple of weeks!" I called out as Mom and Dad successfully went through the security doors.
"See you Sarah!" Dad struggled with some of the carry-on while Mom waved. I could barely hear her shout back over the din as they disappeared. "Have fun you two. Tim. Take care of your sister!"
My arm was still waving bye as Sarah grabbed me by the arm. "Come on!"
Dad was very frugal; read "cheap". Even though we were just seeing them off, Dad wanted to park in the furthest, cheapest parking spot in the world. Of course, thanks to Mom, and just like the vacation, she directed him otherwise and we ended up parking pretty close to the actual terminal which was a good thing because I think Sarah would have raped me right then and there in the airport departure lounge.
I thought Sarah wanted to rush home and do it in private, but she had other ideas. I went to unlock the doors and moved to the driver side. Sarah just pushed me towards the rear. She ordered me to. "Open the trunk!"
I didn't understand but popped it anyways. Even before the lid was up all the way, Sarah was on her knees in front of me and fished out my semi-hard cock. The popped trunk hid us from by-passers and the chest high wall shielded us from being seen by any one observing from the terminal.
Sarah was a fantastic cock sucker. I was hard and down her throat in seconds. "Oh god that feels so good! I love it when you suck me off."
I held the back of her head as Sarah worked her head back and forth. Her hand was under her short skirt, between her legs and rubbed her cunt.
She gasped for breathe as she pushed my hips back and let my cock go. She braced her hands against the half wall. "Fuck me! Put it inside me, Tim. Mom told you to take care of me so take care of me!"
I pulled her skirt up over her ass. Sarah wasn't wearing any panties. "Oh my god, Sarah. Your cunt is gaping open for me already!"
Sarah replied. "Hurry up and put it in me!"
Sarah's knees buckled as I pushed my foot long into her slick open hole from behind. I sat back on the edge of the open truck. Sarah bounced up and down on my lap. While we were hidden by the wall, anyone across the road seeing us would probably be able to figure out what was going on.
Sarah slammed her ass into my lap as hard as she could. I pushed up at the same time. I could feel her squeeze her cunt tight around my shaft. "Cum inside me, Tim! I want to feel you fill my cunt with your cream!"
I wasn't able to hold back any longer anyways and started blasting my white juice inside her. The echoes of "Uuuh! Uuuh! Uuuh...!" bounced around inside the concrete parking level.
Satisfied for now, we rested to recover. I still sat on the lip of the open trunk while Sarah sat on my lap with me still inside her. She was slightly bent over and rested her hands on the half-wall as she panted and spasmed. I could feel some of our cream ooze out and over my balls. It would be great to stay there to recover for a while longer but we were interrupted.
"Hey! You guys can't do that here!" Sarah and I looked towards the voice to see airport security. It took a couple of seconds for us to comprehend. "I said you guys need to stop what you're doing or I'll have to call the police."
Sarah rose off my dick. Her skirt fell below her bum while I quickly tried to shove my still rather firm dick back in my pants. The zip opening was too small and I had to undo my pants to stuff myself away. I heard a gasp come from the open mouth of the security guy... girl! "He was a female. I mean she was a female!" I read her badge, "Terri Harper." Even with her uniform on and seemingly no make-up, Terri looked rather attractive. Mid-twenties and 5'6" tall. Her blond hair pulled back in a pony-tail under her cap. Her breasts pushed out the tight, form-fitting shirt she wore. She filled her tapered trousers very nicely.
"Sorry." I muttered back to her. "We thought we were hidden enough."
Terri pointed up towards a security camera that neither Sarah nor I realised was there. She spoke into her radio. "This is Six-nine! Okay I took care of the situation."
I zipped myself up. My dick hung down along the inside of my left thigh and dripped down my leg. I closed the trunk. Sarah was already in the car as Terri escorted me to the driver side. Her hand dropped to my tight and ran the length of my half hard cock. "My god! How big are you?"
Confused, I mumbled. "Er... 12 inches hard?"
"I would love to feel that inside me." She confessed and handed me her business card. She pressed her buxom body against me and whispered in my ear. "Let me know if you ever leave your girlfriend."
