My twin sister Jessica finally gave in and agreed to have sex with me on the first day of the following month. Only three more weeks and I would be in heaven.
Sis and I shared an apartment during our college years as our parents live in a small town some two hundred miles to the north. Our rented apartment was in a large building close to our campus and included two bedrooms, a kitchen, a bathroom and a combined living dining area.
Jessica was a serious student and, at the time, had not shown much interest in boys. I had enjoyed the company of a couple of girls in the last few months but I had not invited them to the apartment. Since Jessica was my twin sister, I had never thought there would come a day when she would turn me on.
I'm an average guy, 5-foot-9 and 170 pounds but I work out and I'm in excellent shape. My sister is something like 5-foot-2 and very slim. My friends say she's beautiful but way too skinny, scrawny even. I never gave the matter much thought. Things were quiet between us until one day when I came back from school earlier than usual and horny as a stud and there was my sister, sprawled on our couch and watching some reality show in all her skinny glory, with almost no clothes on. A tiny cloth triangle barely covered the two-inch gap between her slim thighs and there was a narrow strip of fabric in the general vicinity of her breasts. There must have been boobs on her but I had never really noticed them. For some reason and for the first time ever, I imagined myself fucking her, scrawniness and all. I hurried to the bathroom and jerked off, ejaculating quickly as I thought of Jessica.
I showered and put on a tee with boxer shorts then I went back to our living area. "What's this, Sis, no class today?"
"Nah..." She looked up. "Feeling better now, Bro?" She smirked and I knew she was on to my having just jacked off.
"Don't you ever get horny?"
"Horny? What's that?"
"Yeah, right. You seem to be studying all the time but I saw you watching porn on your notebook the other night. Looks like you're horny too."
Jessica glanced at me briefly then went back to her soap. "I'm horny all right; my problem is I don't have a boyfriend."
I had looked around and found Jessica's vibrator but I had never heard her using it. Given my sudden interest in my sister, I saw an opportunity.
"I can help you with the sex, Jess, you're very pretty and you turn me on."
My sister looked at me and blushed to the roots of her wavy auburn hair.
"You would do it with me?"
"In the blink of an eye. You're hot. I get horny just thinking about you."
Jessica sat up straight, put her hands in her lap and crossed her slender legs.
"My twin brother, of all people. And how long have you had the hots for me?"
"A while now. I had a good look at you our last time up north and I had to jack off right away."
A month before this, we had driven north to celebrate our eighteenth birthday with our parents and it was a good thing they were out shopping early on the following morning because, upon getting up, I came upon Jessica barefoot in our parents' kitchen, making coffee while wearing nothing but a very short, almost transparent nightie.
"Well, I never thought I'd admit this to you Matt but one of the reasons I don't have a man in my life is you, it's because of you, in a way. I was only twelve when I realized I was getting turned on, and by you. What crap is that! I've often had to finger myself while thinking of you. I'm not a virgin but my few times with men were spoiled with thoughts of you."
"Now you've got me hard as a stud, Sis. I'm ready when you are."
"Take it easy. Talking about it and actually doing it are two different things. We can't do anything about it because it's incest."
"So? Who's to know?"
"I, for one. I can't. I'd never be able to do the real thing with you."
