Riley pushes further.

Riley pulls your zipper and frees your cock before you can blink. It springs out violently, and she holds it in both hands, staring at it.
"Wow...daddy. It's thicker than my daddy toy. Haha... this is my new daddy toy." She drops to her knees, and pops the head into her mouth.
"Riley....nnnooo....mmmmph...oh shit...." it is indescribable, the feeling of watching Riley take your cockhead into her mouth. Her lips, her tongue... they are perfectly caressing you dick. Your brain is lit up with sirens and warnings and SYSTEM FAILURE SYSTEMFAILURESYSTEMFAILURE................. You groan as she takes you deeper, running her tongue down to the base of your cock.
"Can't.... can't do this, baby girl..."
She pops free. "I'm already doing it, daddy. Just let it happen."
