The girls really did look great in their dresses, sitting back in the limo as we made our way to the vineyard. It was just a few minutes into our ride and Keith was already on his second drink, and poured each of us a second round as well. Keith and Katie were sitting across from me and Ally, so I had a great view of Katie as she sat with her legs a little further apart than necessary. Keith, after pouring our drinks, played with the electronics until he found some romantic music to play in our compartment, and figured out how to put up the divider that blocked the driver's view of our area. Now we had some good music, and full privacy for the remainder of our trip to the Vineyard, which, by the speed and route the driver was taking, I was sure would take us an hour or more.
Ally sat very close to me while sipping her drink. I'm not sure what you call the drinks Keith poured, but they tasted like they were 90% alcohol and 10% mixer of some sort.
As we got comfortable, I noticed Keith snuggling up to Katie, resting his free hand on her bare knee; her dress had ridden up so that most of her thigh was showing, and part of her ass as well. Keith started rubbing the inside of Katie's leg, and she parted her knees further apart to give him more freedom for movement.
Keith started rubbing the inside of Katie's thigh, all the way up to her crotch, and by the expression on her face, she was enjoying it. Katie sat her drink down on the side table and threw her arms around her brother, and brought him in for a deep kiss. While kissing his sister Keith ran his fingers up to her pussy and started playing with her. I had a clear view of all the action between Katie's legs. Keith had pushed her underwear to the side and slid two of his fingers into his sister's pussy. Katie was gyrating against his fingers while kissing him passionately. Keith kept up rubbing Katie. I watched as they kissed, catching a glimpse of Katie's tongue as it entered Keith's mouth, and watched as he sucked on her tongue while continuing to rub her. Katie continued the kiss, and then dropped her hand to Keith's crotch and began rubbing him through his pants. The two of them were getting pretty hot with each other as Ally and I sat, consuming our drinks and watching the two siblings go at it.
After a few minutes, Keith broke the action with his sister to refill his drink, and as he did so, he refiled ours as well. By this time, Keith was already a couple of drinks ahead of the rest of us, and I was wondering if he would even be sober by the time we reached the vineyard.
Ally slid down a little in her seat, took the drink from Keith, and started sipping away at it as we both watched Keith and Katie return to action. They were both hot, and it was quite erotic for the two of us to watch them making out and feeling each other.
Keith took a huge drink of his concoction and then sat his glass down, and started back in on Katie. The two of them were tightly embraced, kissing passionately, and feeling each other up.
Keith finally, with both hands, reached underneath Katie's dress and pulled off her bikini's, tossing them on the floor. He spread her legs apart while fingering her. Katie reached down and fumbled with his zipper, until Keith went ahead and unzipped his pants and pulled out his monster cock. I could see Ally's interest pickup when Keith pulled out his cock. I swear she would have gone down on it right then if it were offered.
Katie got up and sat down on Keith's lap, facing us. Keith held up his erect cock, placed it at the entrance to Katie's pussy, and she not so gracefully sat down on it, taking it all the way. Katie started moving up and down on Keith's cock, with her pussy and his cock and balls all facing us. Katie started moaning loudly at this point, and it was apparent that she was getting off on her brother's cock. Keith reached up and lowered the top of Katie's dress, so that both breasts were now exposed, and he was rubbing her hard nipples. The sight of these two awesome looking siblings going at it brought my cock to full staff, which did not go unnoticed by my sister, Ally.
Ally reached over and started rubbing my erect cock through my pants, and then unzipped them and pulled my cock out. She moved around and got on the floor of the car on her knees and started licking the head of my cock. Not wanting to get my pants all messed up, I reached down and removed them along with my underwear at the same time and tossed them on the chair next to us. Ally leaned forward and took my whole cock into her mouth and started sucking. Her mouth was ice cold due to the drink she has been sipping on, but it soon warmed up. Watching Keith and Katie fucking with my sister sucking my cock, I knew that I wasn't going to last long. Hell, I was about to cum from watching the two of them go at it.
Ally continued working my cock. Her wet mouth slid freely up and down my shaft. I loved the expression on her face as she sucked me off. God, I loved my sister. I don't know how we got so fucking messed up and all, but I knew that I really did love her.
Ally continued sucking my cock while twisting her hand around my shaft as she moved her mouth up and down on my shaft. I reached down and held her head in my hands as I started driving my cock in and out of her mouth, face fucking my sister. God it felt awesome, too. I was so absorbed with the blow job my sister was giving me, I failed to notice that Keith and Katie had complete stripped down at some point and were fucking each other hard now, right on the bench seat across from us.
Ally continued sucking my cock as I watched Keith and Katie fuck away. The sight of those two was really awesome. Both of them have killer bodies, and knowing that they were brother and sister made it that much more erotic for me.
Looking back at my sister, I was amazed at the masterful job she was doing on my cock. I continued face fucking her until I knew I was about to explode.
"Hey, sweetie, I'm gonna cum,"
Ally didn't respond. She just kept sucking me like she wanted to milk the cum out of my cock.
"Oh shit, Ally, here it comes," I said as I started ejaculating into her mouth, while Ally kept sucking the cum out of me. I pumped several loads into my sister's sweet mouth, and she took it all. After I came, Ally crawled back up and kissed me hard, sliding her tongue and a good part of my load into my mouth as she did so. I held her face tight against mine and kissed her hard.
After the kiss, I felt that I owed Ally one, so I pressed her back so that she was lying on the bench seat with one leg on the seat and the other hanging off of it. I reached under her dress and pulled off her bikini panties, spread her legs, and went down on her. God, she tasted so fucking sweet. I started licking my sister's bare pussy, circling it with my tongue while I traced my fingers along the insides of her upper thighs. My sister had the softest skin, and I loved the feeling of my fingers against her flesh, especially her thighs. God, I loved her.
I pressed my mouth fully on Ally's pussy and started sucking at her flaps, while running my fingers along her slit. I wanted to make her feel as fucking good as she made me feel with that fantastic blow job.
Ally pressed her pussy against my mouth and said, "God, brother, I love it when you eat me. God I love your tongue deep inside of me. Keep licking me."
I did so, too. I loved the taste of my sister's pussy, and loved the pleasure it brought to her, and if the moans meant anything, this was bringing her much pleasure.
I looked over at Keith and Katie, and now Keith was sitting there, soft cock hanging out of his pants, head leaning back against the side of the car, and Katie resting her head in his lap, her mouth just above his flaccid cock. I could see the cum dripping out of her pussy as her legs were hanging over the side of the seat. Both were still totally nude and resting.
I started licking Ally harder, sticking my tongue as deep inside of her as I possibly could, lapping away at her juices as she continued moaning in pleasure. I slid Ally down a little so that her legs were hanging over the side of the seat, wide apart, and her ass was just at the edge of the seat. I pressed her knees a little wider apart, laid her ass forward a bit, and licked from her pussy to her sweet pucker, gliding my tongue over her hole several times as I went back and forth from her pussy to her ass. Ally was squirming against my mouth as I licked her out. I continued this action for nearly fifteen minutes, when I could tell by her contracting pussy that my sister was having her orgasm. As she came, she also squirted. She doesn't do this all the time, but sometimes, especially following oral sex, Ally squirts her juices. I cupped my mouth around her pussy so none of the juices would escape, and sucked all of it into my mouth, and swallowed. I loved the taste of my sister's ejaculate.
I don't remember what time it was, or how long we'd been gone, but I knew that we must be getting close to the vineyard. I moved over to the intercom between the back part of the limo and the driver, and noticed that it was on "talk," so the driver, although he could not see what was going on in the cabin, certainly could hear. I asked him how long until we would arrive at the vineyard, and he said that it would be no longer than ten or fifteen minutes; just enough time, I thought, for the four of us to get our clothes back on. I got everyone's attention and told them that we needed to get dressed and that we'd be at the vineyard soon.
"Well, I certainly worked up an appetite," Ally said, laughing.
"So did they," I replied, nodding to Keith and Katie, who fucked most of the trip. They looked like they were done for the night, but I reminded them that we have a long night ahead of us, and they needed to dress for dinner.
The four of us managed to get back into our clothes, and our respective sisters tidied us up so we looked presentable. Katie and Ally made sure that each other looked good for dinner, and by the time we all finished, we had arrived at the restaurant.
