You get no choice

You opened your mouth, about to tell him no. But he took that opportunity to shove the head if his dick straight into your mouth, so all you ended up saying, was "Mmph"

You tried to protest, but your "Mmphs," as he slowly slid his dick in and out of your mouth, just egged him on more.

You tried to bite down, but all he could say, was "Damn I love it when you do that!" What kind of a monster loved their dick getting bitten.

You resigned yourself to this, your first ever blowjob as a girl, or at least the first you remembered, Laina evidently had already given at least one.

Luckily for you, he didn't last long, as he pulled his dick put after only a couple of minutes, and blasted his warm sticky semen onto your face,

"Thanks, sis!" He breathed heavily, and went to wipe his dick on a towel, before leaving the bathroom. Leaving you to clean his cum from your face.

You can't believe that just happened...
