Emily and I cleaned up as best we could and made our selves look presentable. We were only a few minutes out from the college and our parents would be able to tell if something was wrong.
"Are you ready Em?" I asked Emily as we pulled into the parking lot.
"Ready as I can be." She said finishing getting her skirt flattened out.
We pulled up around the corner of the main administration building of the college and saw all the other students and their parents getting out of cars, unloading luggage, some parents were hugging their kids crying. Our dad pulled around into the parking lot and we started getting out of the car. Emily was stood up off of my lap and I could see her perfect pussy peeking out under her skirt. She had to get around some of our stuff so she stopped for a second giving me an even better view. I could see that a small bit of my cum was still dripping out of her. It was all I could do to not stand up and start fucking her from behind right then and there in front of our parents.
Emily managed to get out of the car and I followed her. Our parents were already out looking around.
"Wow! What a great campus!" our mother said.
"Way nicer than ours was." our dad added in.
"I really like all the pine trees." Emily said looking back at me as I got out of the car.
We looked around and stretched our legs for a minute then started walking toward the greeting area. It took us about 3 hours to find our dorms and get everything unloaded into our rooms. When I went into my dorm the RA told me that my roommate had backed out last minute and that unfortunately they weren't able to fit another person in so I would have the room to myself this semester. It was a nice sized room with a window over looking the main grassy park area of the campus. As soon as I could I found Emily and told her.
"Em, my roommate backed out last minute I got the room all to myself!" I told her after we had said good bye to our parents for the night. They were going to stay in a hotel that night and join us for all the orientation events tomorrow.
"Really!?" She said looking at me knowingly.
"Yup and I think you and are should break it in tonight." I said slipping my finger under the band of her skirt pulling her toward me.
Emily wrapped her arms around me "I'll come by tonight after my dorm finishes with all the greeting stuff okay?"
"Good." I said letting her go and telling her where my room was.
We didn't see each other again until I heard a knock on my door around midnight. I went over to the door and there Emily was still wearing that sexy skirt that I knew she didn't have any panties on underneath. I smiled at her and grabbed her hand pulling her into my room.
"What do you think?" I said gesturing toward my room. I had gotten everything unpacked and organized. I even made my bed knowing that I would hopefully be messing it up with my sister tonight.
"It's nice! way bigger than mine. My roommate and I even have bunk beds and yours is bigger."
"I know, I got lucky."
"Hey John." She said walking over to my bed and sitting down. "What are we doing here? I mean what are you and I now?"
"I know." I said walking over and sitting down next to her. "I've been thinking about that too." I paused for a second then said. "I know I love you. And I know we aren't just brother and sister now it's more than that. I never really thought of it until now but I like just hanging out with you like you were a girlfriend honestly. You're funny, cute, Smart I just like spending time with you and to me that's just like you being my girlfriend ya know."
She looked at me smiling. "I know exactly what you mean. I was kinda afraid I was just some kind of kinky turn on for you. I know that some guys are into incest and guess you are too." She said laughing.
"Well I guess you are too!" I said poking her in the stomach.
"I am. I'll admit I've been attracted to you for awhile. It was always some sick fantasy I had but I never actually thought anything would happen."
"To be honest I was the same way. I always felt bad checking you out when you weren't looking. I thought you might think of me as some sick freak."
"Nope, I think it's really nice. You have always been really kind to me John and I want to make you happy."
"Oh you do sis." I could feel my boner starting to poke up through my shorts at this point. Emily glanced down and noticed.
"I can see that." She said giggling. She looked back at me and slid her hand over my leg and started rubbing my cock.
"My RA took us all to the store today to get some stuff. I got the pill while I was there." She said smiling at me.
"I was going to ask if I should use this." I said pulling a condom out of my pocket. "We went to the store today too." I laughed and threw the condom on the floor.
"I want to try something." I said standing up. I grabbed her hand and pulled her up with me. My boner was sticking through my shorts rubbing against her. I spun her around pressing my boner against her ass and grabbing both of her tits with my hands. "When you got out of the car I could see your pussy from behind and I saw my cum dripping out of it. I really want to fuck you doggy style little sis." I said massaging her breasts through her shirt and bra. My boner was wedged in-between her ass cheeks.
