You stroke harder. Fuck it.

You were not expecting to jerk off to your step sister when you woke up ten minutes ago, but, fuck. Who could resist?

"Ha!" I grab onto the cabinet, pulling my other leg onto the counter. Kneeling there, thighs wide, I reach up and into the cabinet to pull out the last bag of coffee grounds. My pussy spreads wide right at eye level for you as I set it down on the counter.

"Um..." As I turn my head to try and slide back onto the ground I spot you, my step brother, wildly jerking at your cock.

Mostly, I'm stunned. Then I snort back a laugh as you realize you've just been caught and freeze.

Grinning ear to ear, I slip down off the counter, my bare breasts bouncing heavily with the jolt. "I had no idea you were back in town?" I say, calmly stepping up to you, wrapping my fingertips around your cock, teasing them gently along its length.

"I, uh, well..." Looking expectantly up at you, honestly keenly interested in whatever it is you're about to say, I calmly settle down onto my knees, mouth slipping around you, fingertips replaced with the teasing of my tongue. "Oh jesus fuck..." You manage, almost instantly bursting into me. You certainly had already gotten yourself close!

I suck in, drawing out each burst of warmth as it comes, as you cum, and quickly swallowing it down, until I can tell you've stopped.

Rocking onto my feet, I smile a toothy grin. "Welcome home, big brother!"
