I jerk off over Sierra's face, fuck her throat, slap her cunt, and come onto the tongue she sticks out for me.
This is also a great example of in-scene negotiation. I'm jerking off near her face with a finger in her mouth, and she's holding it open and looking up at me. From the teaser:
"That looks kinda like consent."
"For what?!"
"Me to come down your throat"
"Yeah!" (nodding, masturbating)
Her fingers are extra-busy on her clit while she's licking my balls, and her glee after swallowing my come is adorable.
