The opening moves

You imagined her undressing. She was removing her clothes opposite from her opponent… silence...

"Give it your best shot, try to conquer this perfect body."

Silence again...you presumed this was what happens if a man saw her naked body.

You heard a slight noise, a zipper...ok he too was now undressing. Once naked and at full must he broke the silence “How bad do you want my cock, little girl?”

“Not bad”, she answered and you heard a smile in her voice. “So do you want me to suck it first or do you just want me to bend over so you can pound me like a piston?”

That was the moment he grabbed her shoulders, pulled her towards his cock and commanded to “Open that filthy mouth, you little slut”.

This was a mistake, because after that moment, there were no breaks, no moments to catch a breath. Through the door came the sound of a full phlegmed spit, slurping, moans and groans. Your sister was relentless and inexhaustible, as she went after his cock. You reckoned it could be fatal if she let him get ahead, control the momentum and let him steam up first. And so she let his groans fill the room together with the sound of her mouth slobber over his dick.

After what you figure is a decent amount of time you hear her say “Looks like someone’s about to lose.”

“Aww fuck! Cumming!”

"God thats sexy baby. Let it go! I wanna feeling your warm thick cum all over my body."

"SHIIIIITTT!"

Shortly after you heard her gurgle and after two seconds say "Got any more where that came from?"

_Wow, my sister swallowed _you thought, and she won.

But little did you know this was but the beginning. Yes, your sister started out strong in the battle against the stranger in your house. Yes, she drained his balls early on....
