"When my sister told that, it was like a magical phrase...my balls seemed to instantly refill with sperm, and my cock got harder than ever! But my naughty little sister still had to be punished, so I spanked her, then popped her butt-cherry as well! She squealed in delight and pushed back eagerly on my cock, and within no time at all, I was filling her ass with cum as well!"
"My little sister had learned to love it when her big brother licked and tongued her pussy and crack, but she had no idea that this vacation would see things progress by me introducing my huge cock to both her tight holes! By the time we went home, she was addicted to the feeling of my cock squirting in her ass and in her tummy."
"I smirked when she said she was still a virgin, then offered, "We could change that, you know." Her clothes were off in seconds and by the time we passed out around 2AM I'd filled her with at least six massive loads of cum!"
"The fact that she spent the rest of the weekend with me between her legs, blasting load after load deep into her tummy, told her my answer was a resounding "YES!""
