"I'll go nice and slow, okay," I whispered at my sister.
She scowled, a horny smug on her face. "I don't need nice and slow! And I'm the one winning this round again!!"
She pushed me off of her and then straddled me instead. I watched as she stroked my cock with her small, soft hands a few times before she grabbed it, aligning it with her beautiful slit and slowly lowered on it. It was electrifying when the tip of my cock first made contact with her pussy. Her slit glistened, juices practically dripping out. As she kept lowering herself, her labia started stretching out more and more, little by little. I held my breath as I saw my stiff cock entering her, stretching out her virgin cunt as she kept lowering. I kept waiting for her to pull up and complain that it hurt too much, but she never did.
Despite having a small body, my sister seemed to be strong willed.
