You slide a hand under her dress

As soon as the driver gets on the road, Adela pounces on you. Before you know it, her arms around your torso and her tongue is wrestling around in your mouth. After a second or so, you gain your composure and put a hand on her soft thigh. That hand then snakes its way under her skirt, and pass the thong she's wearing. Two of your fingers enter her soaking wet slit, causing her to whimper.

"Are you doing what I think I'm doing?" The driver asks.

"Sure am."

You begin thrusting your fingers back and forth, causing Adela to moan as you kiss her neck. She's completely lost in the sensation of your touch. She doesn't care that the driver is exchanging constant glances with the mirror, or about anyone inside. She only cares about the orgasm you're pushing her towards. When the driver pulls up, Adela states "I'm cumming..."

"Cum for me."

Adela's body quakes on the backseat of a stranger's car. As she shudders, you turn to the driver and say "We here?"

"Yeah man."

"Perfect."

You pull out your wallet and hand him $20. "Keep the change."

"Thanks man."

You then turn to Adela. "Shall we go inside?"

"Yes."

The two of you head to Adela's apartment. Your erection is straining against your pants, begging for attention. When Adela gets to her door, she does her best to unlock it so the both of you can get inside and continue your night.
