My Sis, Carrie, and I were driving home to Minneapolis for Christmas. We’re both in college at Northwestern. I’m a freshman and she’s a junior. Two years difference in age. If she wasn’t my Sis, I’d have long ago tried everything I could to get in her pants. She oozed sex. Everything about her screamed it: her smile—enchanting, her long blond hair—enticing, her ass—exquisite, her tits—C-cup perfection. Hell, I masturbated regularly while holding one of her bras to my face and inhaling her scent. I know, I’m a perv. Who thinks of his sis like that? But she knew my thoughts, or at least it strongly seemed that way.
In high school, she’d walk into my room in just a bra and panties, usually thong panties, and talk about something totally innocuous, like a new movie or song. Is that normal? No. She was purposefully teasing me. I was sixteen and still a virgin—a virgin with no girlfriend. She was two years into an active sex life. I couldn’t keep count of her boyfriends.
Her leaving for college gave me a bit of a break—two more years of high school without her presence. But she’d text me pics of her. Nothing pornographic, but somehow they always carried a tinge of sex. It was all a big joke to her. I’d asked her to stop using our brother-sister relationship as the reason. She told me to grow up. “It’s just sex. Get laid for God’s sake and enjoy it.” Like that wasn’t an almost constant thought.
Then it finally happened. Julie Morris, my dream girl, actually asked me out. One day, after school, at her house (her parents both worked) we did it—three times! I was in heaven. That was the good. The bad was my new knowledge and feelings only increased my thoughts of Carrie.
So, there we were, driving along I-90 towards home. “Let’s have some fun!” she blurted and pulled off her T-shirt and bra.
“Carrie, what the fuck!?”
I was startled and thrilled at the same time. I’d only seen her naked once. That was a chance encounter in our home bathroom. It was a one-second flash. She'd grabbed a towel to cover herself.
Now her tits were out for my full appreciation—appreciate them I did—superbly magnificent.
“When you get up to the cab of that truck you're passing, slow down and honk. I want to give him a good look. It’s Christmas. Time for presents. This is going to be mine.”
“Jesus Christ,” I muttered. Such a Carrie move, but I did as she asked.
She pushed them against the window as I honked several times. I couldn’t see his reaction, but the continuous blasts from his air horn told the story. I passed truck after truck—always the same reaction. Then there was a bit of a break in the truck traffic, so she sat back in the seat.
“Hey Bro, this is getting me really turned on.” She started to let the seat back and unzip her jeans. “I’m going to get myself off. I assume you don’t mind.”
“Dammit Carrie! I’m sitting here with a hardon, and now you're going to get off as I watch? Give me a break... please!”
“Don’t worry Bro. I’ll take care of you before we get off the interstate. My Christmas present to you.”
I was speechless. What the fuck did that mean? By the time I’d barely processed all that, she was already rubbing and moaning. I turned up the radio volume. Within a few minutes, “Oh fuck ya! Fuck, fuck, fuck! Damn, that was good!” She turned to me sporting a big grin. “That was great,” she said. As if I hadn't figured that out. Then she pulled her jeans completely off, turned down the volume, and started moving towards me. “I’m going to give the next few trucks something they’ll really remember.”
With that, she was on her hands and knees, moving towards me. Just the sight of her tits hanging down, swaying back and forth, almost put me over the edge.
“Sis, what the fuck are you doing? I’m barely keeping the car on the road.”
“Wanna touch them?" she teased. "I’m gonna give the next few truckers my rear-view. Then I'm giving you your present, well, one of your presents anyway.”
So, the next few truckers got that view. During that time her nipples were brushing across my right arm, and she'd begun undoing my belt. My thoughts were a jumble. My sister was about to give me a blowjob as I drove 75 mph on the interstate. I’d never wanted anything more in my life, but not from my sister. This was so wrong—wasn’t it? I was so horny. I knew I wasn’t thinking straight. But so what? She wanted to, I wanted her to, nothing bad could happen. Yeah, right.
“Sis, aren’t we taking this a bit too far? If you're planning what I think you’re planning—”
“Shut up and drive,” she said as my cock popped free. “Jesus Christ Bro! How did I not know this!? Chrissy [my current girlfriend] must be in heaven.”
I suppressed a laugh. “She’s never complained.”
“I guess not! Who’d have thought?” she said as her lips engulfed me and began moving down.
My whole body tensed as my hips reflexively pushed up. “God damn Sis! Who’d have thought you could suck cock this good. Fuck!”
She lifted long enough to say, “Merry fuckin' Christmas Jake. You know, we’re not done. Not even close. I’m not missing out on this!”
Her head began bobbing up and down in rhythm with her right hand.
Soon... "Goddamn Sis, I’m almost there. Fuck you’re good! You better swallow it all.”
“Mm-hmm!”
“NOW! Fuck! I’m cumming. Oh god, I can’t believe it.” Then I just moaned with each spurt.
She got every drop and looked up smiling. “Mmm, you're yummy! This is really going to be a Merry fuckin' Christmas, isn’t it?”
“Fuckin'-A right it is!”
