Line them all up.
From Create Your Own Story
Newly excited by the addition of another girl, early twenties by the looks of her, black hair, with a nicely rounded body and a mouth-watering set of D-cups inside her bikini, you decide on a new plan.
"Yes, beautiful, you can join the party. In fact," you say, "I want all four of you to take off your bottoms and line up on your hands and knees."
Carrie looks a little annoyed at this, but does as you ask. The new girl immediately drops her bikini bottom. You notice, to your pleasure, that she has a thick, neatly trimmed patch around her pussy. She drops on all fours and teasingly wiggles her round ass at you. Nicole, still convinced she's in a dream, puts her tight, athletic ass right next to it.
The only hold-out is Jessica. She stares hungrily at your newly enlarged cock, but still hesitates. You look her in the eyes and pump your dick a couple of times, squeezing out a droplet of pre-cum. This seems to decide her, and she drops her bikini and lines up next to Nicole.
