You fuck her.

"Come sit on my dick reverse cowgirl style while masturbating." you command Scarlett

"Who said you got to order me about?" she replies

"Oh right, I wish you'd follow my orders" you respond

"...well then, come here big dick." she states before coming over to you as you lie down.

As you lie on the ground, with your dick already rock hard she grabs hold of it and rubs it against her pussy lips. They quickly get wet and you feel her press the head of your cock inside.

"Fuuuuuck, you're so big" she moans

You decide this is taking too long though and quickly slam her down so the entire length of your cock is inside of her.

"ohhhh fuck! That feels amazing! Where's your cock been my entire life?!" she states

"I wish you'd start masturbating while bouncing up and down on my big dick" you tell her.

As Scarlett bounces up and down on your dick, you start caressing your nipples. Occasionally pulling them gently. You can feel your own pussy starting to get soaking wet. You're tempted to swap when you hear her.

"Oh my god, my dick is already close to cumming, fuckfuckfuck. I wanna cum on your faceee" she squeals
