Fuck it...keep going

Figuring that you're just vastly overestimating Manda's perceptive skills, you let Lacey unzip your pants the rest of the way, giving her the freedom to do whatever she wanted to with your body, without the restriction of clothing. You allow yourself to be caught up in the moment and even reach underneath her jeans, toying with the lace of her underwear and feeling the smoothness of the skin under her shirt.

You're about to begin undressing her as well when Lacey shows surprising initiative, moving down your body with her mouth, kissing whatever exposed areas she finds on the way. Eventually, she arrives at your fully erect cock and doesn't show any hesitation in wrapping her mouth around it. The inside of her mouth feels hot and wet as she moves her tongue up back and forth across your shaft with more talent than you would expect from her. You run your fingers through her hair and stare at the ceiling while you allow her to work more and more of you into her mouth. She reaches in between your legs and strokes the inside of your thigh, mixing the cold touch of her fingers with the warmness of her breath. Just as you wonder whether it would be appropriate to let her finish you off in the car with other people around, Amanda notices that the two of you are no longer struggling like you were earlier and looks in the rear view mirror to see Lacey's head between your legs.

"What the FUCK!" She shouts, slamming on the breaks. "Are you guys serious?"

Lacey snaps her head back up in an attempt to pretend that you weren't doing anything, even though you're still laying there fully erect with your pants at your waist. You can see her face getting red with embarrassment, and when you catch her eye you wink at her, obviously not helping the situation any.

"I can't be having that sort of thing in my back seat, you two..." Amanda continues, still surprised and...perhaps...a little bit jealous. "I'm going to stop for gas inna bit and when I do, I want Alex and Claire to switch places."

Lacey sounds as if she’s going to try and justify her actions for a bit, but she obviously changed her mind and just sat back in her seat, still blushing. You zip your pants sulkily and sit upright, staring out the window so as not to make Lacey any more uncomfortable. Unless Claire and Lacey also secretly had the hots for each other, you could tell it was going to be a boring ride for the rest of the car trip...
