You pick one of the stalls and introduce yourself.

After giving her your phone and instructing her to record herself, Emma bounds off to one of the stalls like a kid at a theme park. You pick a stall for yourself, once you see which ones have women waiting in the opposite booth, and lock yourself inside. At the sound of you closing the latch, a mouth appears at the hole. It's a bit dark in here, but you can see she has full lips and a tongue that darts out to moisten them. She grins and clenches her teeth together, and gives a playful, sexy growl. This lady has some personality, you see.

You draw your cock from it's resting place, letting it hang in the air rigid and ready for action. You give it a couple of strokes, just to let the lady on the other side hear the squelching of your sweat and precum, taunting her with your tempting tool. Then, you press your hips up against the stall wall and let your cock jut out into the void. As you close your eyes and let your imagination run free, you start to feel the slut getting friendly with you. You feel a finger and thumb encircle your length and start to lightly stroke you, rotating as they do. You imagine a hot chick from your high school years that you never quite sealed the deal with.

The two fingers become a full hand, wrapped around your length and working your shaft, grip loosening at the base and tightening back up around the head. A tongue joins the party, dancing on the end of your dick and making all sorts of hot sticky sounds. Your high school fantasy has moved from the girl who got away to your old principal, an ice-cold vixen who wore the tightest button-downs you've ever seen on a woman. You saw your fair share of her after getting caught with girls behind the bleachers, in the bathrooms, one time fingering in the back of a classroom. You're still fixated on her as the slut in the booth seals her lips around your cockhead and lovingly nibbles her way down the shaft.
