Intro: "The young couple NAME_1 and NAME_2 need a ride to the airport since none of them got a car or license. Their older neighbor NAME_3 agrees to drive them. NAME_1 rides in the back and NAME_2 sits in the passenger seat while NAME_3 is driving. It's a long trip and NAME_3's eyes begin to wander. NAME_2 is a cute young blonde with supple breasts and an otherwise slim and petite body. NAME_3's hand also begins wandering, from the gear stick to the girl's thigh. She is wearing a cute short summer dress and his hand ventures under the hem of it.
'How did you plan on paying me, by the way?', NAME_3 asks NAME_1, who timidly watches NAME_3's hand from the backseat.
'How about telling your cute girlfriend to take off her dress for me, hm?', NAME_3 adds, grinning.
Weighing their options, the couple finally agrees for NAME_2 to be NAME_3's plaything during the ride."
Flesh out the story, make it extra smutty and hot, at least 10 paragraphs. It ends with NAME_2 reluctantly blowing NAME_3 while he's driving them to the airport without pulling over. She swallows NAME_3's cum while NAME_1 watches, defeated.
