"NAME_1 and his wife NAME_2 won tickets for Disney World but can't go since they don't have a car. Their elderly neighbor NAME_3 agrees to drive them. It's a long trip and NAME_3's right hand starts wandering, from the gear stick to the girl's thigh in the passenger seat next to him. NAME_2 is just 30, a cute brunette with supple breasts and a slim body. She is going commando, wearing a cute short summer dress that is getting hiked up by NAME_3's greedy hand.
'How did you plan on paying me, by the way?', NAME_3 asks NAME_1, who timidly watches NAME_3's hand on his wife's thigh from the backseat.
'How about you tell your cute wife to take off her dress for me?', NAME_3 suggests, grinning.
Weighing their options, NAME_1 hesitantly nods towards NAME_2 to comply with NAME_3's requests. Shyly NAME_2 pulls the light dress over her head, now only wearing her sneakers in the passenger seat, next to NAME_3. Nobody except NAME_1 had seen her like this before. She is very uncomfortable and embarrassed in this situation while NAME_1 is painfully aroused by it.
'Good girl', NAME_3 says to obedient NAME_2. 'Get your pretty lips on this...', he adds while fumbling his hard cock out of his pants.
NAME_2 reluctantly sucks off NAME_3 while he's driving until they arrive at the park's parking lot. She knows how to finish NAME_3 quickly. NAME_1 starts jerking off and taking photos of his wife's mouth around the stranger's shaft, his lust fueled by NAME_2's humiliation. NAME_3 finishes on NAME_2's pretty face while NAME_1 watches, defeated and horny.
Flesh out the story from the perspective of NAME_1 in first person. Make it extra smutty and hot, at least 10 paragraphs of pure filth. NAME_3 doesn't use force, just coersion. Everything happens in a moving car and at NO point is NAME_2 enjoying this.
