The night of my 18th birthday party was always going to be wild, but nobody knew just how wild I wanted to get. That was the night I was going to seduce my brother, whether he wanted it or not.
I should probably back up a bit. My best friend Veronica had been telling me she'd been having sex with her brother for a couple of years. Now, I don't know if she was just saying that to tease me because she could tell I was in love with my older brother Adam, or if she actually did have a legitimate relationship with her own brother. Veronica said she couldn't blame me for wanting Adam; he's 6 feet tall, he has these nice big muscly arms and, thanks to his regular manscaping, his torso is completely hair free. "Fucking delicious," she said. No way in hell I'd disagree.
So once Veronica had put that idea in my head, I couldn't stop thinking about Adam and how to convince him to sleep with me. For a few months, I tried flirting with him, wearing less and less clothing around the house, but nothing worked on him. No matter what I tried, he just laughed at me and called me "kid." After that, I even tried subtle hints to show him that I wasn't just a "horny little girl," like leaving my birth control pill in places that he would see it. Still, nothing.
Well, I was 18 now and like it or not, Adam couldn't deny I was an adult. My party was a fairly average 18th, with lots of cheap drinks, a dozen or so friends from school, and my family all in the backyard. As part one of my plan to get into my brother's pants, I took the liberty of pouring his drinks and mine. For every double strength drink I gave to him, mine had water instead of any alcohol.
By the fourth or fifth drink, I started teasing him, asking, "What's the matter? Can't keep up with your little sister?" By the eighth drink, Adam could barely stand, let alone talk properly. I called out to my dad, asking if I should take Adam to bed. Once he realised what bad shape Adam was in, Dad agreed and praised me for being so responsible. I giggled, telling him that I wasn't a little girl anymore.
Putting one of Adam's bulky arms around my shoulder, I slowly guided him inside, down the hallway and into his room. Thank god I'm fit! I locked the door behind me, then whispered to my brother, "Now I'll show you I'm not a kid anymore." Adam mumbled some kind of nonsense reply.
I pushed him, barely conscious, onto his bed. I kicked off my shoes and unzipped my retro party dress, stripping down to my black bra, undies and stockings. "I've been wanting to do this for years," I reminded Adam. He groaned, most likely in protest. I ignored him and, kneeling on the floor next to his bed, began unbuckling his belt, unzipping his fly and liberating his flaccid penis from his boxers.
My brother moaned when I started massaging the shaft of his circumcised cock. It started off small, but soon it was growing into quite a nice size - thick and long. I spent a minute or two jerking his cock, feeling the warmth and hardness increasing with each stroke. At the same time, I felt a tingling warmth beginning between my legs, and my nipples began to harden against the silky fabric of my bra. I bit my lower lip and smiled, so happy I finally had my big brother right where I wanted him.
