As Sarah and I made our way to the airport, we traveled through an area that had several speed bumps. The bouncing action of my SUV caused her spaghetti strap to fall from her left shoulder. She did nothing to put it back in place, and I kept shooting glances her way to see that the dress fell lower and lower with every bump. Finally, it caught on her nipple. She caught my eye once, and smiled, knowing exactly what I was doing, and what she was doing to me. I was growing hard again at the thought of getting to see her breasts exposed. I made a point to hit the next bump a bit harder, which had the desired effect. Sure enough, her dress dropped, and exposed her left breast in full to my gaze. I had a hard time concentrating on the drive, but what she did next made it even worse. Looking straight ahead, Sarah reached up and slipped the right strap from her shoulder, which, of course, caused her dress to fall, completely exposing both of her supple tits to anyone who wanted to see. Knowing she was on display, my sister pulled the seatbelt strap out away from her body, and let it crumple around her waist.
"Why don't you just take it off," I suggested. So she did. I watched as my stunning sister raised up, and slipped her dress off, and tossed it in the back seat.
"I love it when you do that," I told her.
"What, take off my clothes?"
"Well, yea, but when you get naked in the car. I love that."
Sarah just smiled at me, and turned to look forward again. My compliment of her nudity caused her to flush. I knew she liked being on display, especially for me. As we continued, I watched as her ample breasts bounced with the movement of the car. I reached over to touch them. I cupped her right breast in my hand, and let her left tit rest on my forearm. I was her human bra, and held those luscious titties in place as we continued down the road. Unfortunately, we were nearing the airport, so play time would have to end.
"Are you going to dress before we get there?"
"No, I'll do it when we get to the garage. It's ok...I kind of want to be naked as long as I can."
"Believe me, I want you naked for as long as you can!"
I love my sister wholly. Not just as my sister, but I love her as my soulmate; my lover. But I'm also in love with her body. Every part of her attracts me like a moth to a flame, and I want every part of her to be a part of my life every day. I truly enjoy our sexual acts, as it allows me to show her my love for her. I know that showing her is not a requirement in our relationship, as we both feel the same about each other, but it is certainly satisfying to share that bond with her. When our bodies join in intercourse, we are taken to another world. A world in which our souls mate together, and love is consummated as often as we please. I have never experienced that connection with any other woman, and having done it with my sister, I know there is no other woman I would ever want to even attempt that connection.
Pulling into the airport parking garage, Sarah waited patiently, her hands folder in her lap, as I made my way around to open her door. I took her hand, and admired every exposed part of her exquisite nakedness, and watched in awe as that gorgeous body turned to exit the car. I pulled the nude nymph to me, and kissed her, allowing my hand to slide down her bare back, and squeeze her delicate ass cheeks. I ran a finger up her crack, and quickly grazed her puckered hole. I released her, and closed the door, leaving her exposed to anyone who happened by. I opened the back door and set our suitcase out before retrieving her dress. I helped her into it, feeling a bit of disdain as her body was once again covered. If time had been on our side, I would have fucked her there in the parking garage. As the dress cascaded down to cover her luscious body, I noted how exposed she remained. Any movement at all exposed her perfect cleavage, so I resigned myself to that having to suffice until we arrived. If she bent, though, I could see down the top of her dress, so that was even better. Having spent the past several minutes feasting my eyes on the perfect naked female form had me at full mast, and rapidly expelling my lubricating cock fluid. The front of my shorts were soaked.
"Um...honey?" Sarah started. "Your shorts...and you're hard as a rock! Do you want me to take care of that?"
"We don't have time, baby, but yes, I do want you to take care of it."
"What are you going to do?"
Thinking quickly, I opened the door and grabbed my iPad from the console.
"I can use this to hide my boner."
"Ok, but what about TSA? You can't carry it with you."
"I...I don't know." I replied, completely at a loss, and wishing I had worn underwear.
"Here..." Sarah said. With that, she squatted down in front of me. She pulled my shorts down, and licked the copious amount of precum from them, then turned her attention to my penis. Still flowing, she took it into her mouth and sucked hard to clear me of anything I was retaining. She then used the hem of her dress to wipe my shorts as dry as she could. "Are you sure you can't cum real quick?"
"Sweetheart, I could, but it wouldn't help. I'm with you, and I'm always horny when I'm with you. If I look at you after I cum, I'll just get hard again."
She smiled at that. "Well, let's just go see what we can do." We took off to head inside, Sarah slightly ahead of me as I pulled our suitcase behind. Sure enough, watching her perfect ass leading the way, a breeze slightly lifting her dress, I felt myself start to pump out more moisture. With the silky texture of the material rubbing my precum all over the head of my cock as I walked, it became even stiffer, as I considered doing all sorts of naughty things to my sister's body. Of course, this also made my predicament even more challenging.
We approached the luggage check desk, and Sarah turned to me. She noticed my predicament immediately, and let out a small laugh at it. Fortunately, there was a self-check kiosk, so no one would really notice. I got the check sticker and put it on our suitcase, then we proceeded to the desk. I sighed in relief as we would be able to stand so that no one could see my sticky penis pointing the way. Our bag checked, I now was forced into finding a solution to my problem. With my sister by my side, there was absolutely no way this erection was going to subside. Thinking quickly, I made my way to the men's room. The airport was relatively empty at the time, so I stripped my shorts off, and soaked them in the sink. I wrung the water out as much as I could, and put them back on. Now, with them being wet everywhere, it would hopefully make my moisture problem.
My plan seemed to work. Sarah commented something about it working, all but the tent I was still wearing. We headed to the TSA line, and luckily breezed right through. The agent who checked our identification engaged us, though.
