She hovered over me, grinning down at me. “Are you sure?” She almost laughed as she said it, she knew she was driving me completely insane. Her hand held my cock gently, teasing it against her wet pussy lips.
"Yes, please Jess." She’d been teasing me for months. It started with harmless flirting. Then one day she kissed me. Eventually she touched my cock. We kept doing more and more, until today. Today she finally agreed to fuck me.
But not before she tormented me mercilessly.
"Are you sure? I mean, there’s no going back after this, right?" She smiled down at me, sighing pleasurably as she ran my cock over her clit. "I’m your baby sister, if you fuck me than things will be different forever."
I tried to keep my cool, but I was slowly cracking. “I really want this”
"You’re sure? I mean, if you fuck me now, I’m probably going to want it again."
"I’ll want it too."
"And I may demand it even when it’s inconvenient for you. Like, if you’re over at your girlfriends house, I might make you come home and fuck me. Can you do that?"
"Will you make sure I always cum first?"
"And will you lick me out so I can cum again, even if you’d just finished inside of me?"
My desperation finally reached a boiling point. “Yes! Fuck, Jess. Please, I’ll do anything. I swear I’ll do whatever you want. Please just stop teasing and fuck me.” She had broken me and she knew it, and gave me the biggest smile I’d ever gotten from her. Without another moment of hesitation, she lowered her hips down and her hot pussy swallowed my cock. I groaned and leaned my head back as I felt her inner walls clench tightly around me. Every inch she lowered felt like an eternity, until finally her ass rested on my thighs and my whole cock waited impatiently inside of her.
She just sat there for a moment, looking down at me and smiling as I throbbed inside of her. I could feel her flexing herself around me. If she kept that up for long enough I could cum just from her muscles milking me. She was moaned quietly as she adapted to me inside of her. “Mmm… I like how you feel.” I just grunted. “I think I might want this all to myself.” I opened my eyes and looked at her, and she has a serious look in her eyes. “You’re going to dump your girlfriend.”
In that moment I couldn’t find any reason to argue with her. I just looked her in the eyes and said “I’ll talk to her tomorrow at school.”
Her smile returned, and she leaned down to kiss me deeply. “I think I’m going to have a lot of fun with you, big brother.” As my spine shivered at the thought of what I’d gotten myself into, her hips started to slide up and down on my cock. And at that moment I realized I didn’t care.
His best one of all times. And that sister? I like her. :D
