Chapter Text
The wind ruffled your hair as you and Billy flew down the highway in his blue '79 Camaro. It was nearly dawn, the car's top was down, and you were pretty much alone on the highway. The two of you had been driving since yesterday morning, on your way to Indianapolis for the weekend. Billy sat next to you, in jeans, a denim jacket, and no shirt, hair mussed and looking for all the world like sex incarnate.
The smoking joint between Billy's lips had a faint pink ring around it from your lip gloss, cherry-scented and slightly sticky. Your eyes were closed as you leaned back in the seat, enjoying the early morning quiet and the cool early summer breeze on your face. Billy looked over and smirked. "Damn. Only hit the joint twice and you're already high?"
You shook your head, smiling blissfully. "High off of the world, Billy. Not the joint."
Billy looked you up and down, at your short skirt and short-sleeved button-down, tied up to reveal your stomach and only halfway buttoned down. Your bare feet were propped up on the dash- you were the only person allowed to do that in his beloved car- and your long legs were crossed. He let his eyes wander up and down them, the road all but forgotten.
"Doll, when we get to Indianapolis...we're checking into the first cheap motel room I can find and I'm gonna break its damn bed with you."
You shot him an impish grin. "Why wait?" Billy gave you a confused look, and then he noticed you shifting in your seat, unhindered by your seatbelt, which was forgotten and hung limp. You knelt on the upholstery, making sure to arch your back in a way that presented Billy with a nice view of your ass, and ducked under the arm he had casually rested on the steering wheel. "What are you doing?" he asked, and then he felt the zipper on his jeans slide open, and he shut the hell up, flicking his joint out of the window.
You reached into his jeans and took out his cock, which was already half-hard just from looking at you. You looked up at him through your eyelashes and gave him a few languid strokes. Billy groaned and his eyes fluttered shut.
You smacked him lightly before licking a stripe up his shaft. "Eyes on the road, mister," you said, and then made it your goal to make sure he couldn't.
You took him into your mouth, bobbing your head slowly. The hand that had previously been resting casually on your thigh now went to gather your hair into a makeshift ponytail, and Billy groaned loudly at the feel of your mouth on him. Your cheeks hollowed out as you looked up at him again, and that devilish look in your eyes was just what he'd come to expect from his spitfire girlfriend. The memory of the last party the two of you had been at together floated through his head in the waterfall of thoughts now racing through his head, the way you casually reached a leg out from your place at his side and kicked aside a girl trying to chat him up, and gave her a look when she yelped that clearly said, "Mine. Got a problem with that?"
The car jerked forward and then back to its normal speed as his toes curled slightly. Your lips were leaving a slight smear of lip gloss on him, but he didn't care- fuck, how could he care, when you were sucking him like a goddamn Hoover? His hand gripped the steering wheel tightly, his knuckles almost white. The other hand left your hair for a moment to wander down to your ass, giving it a sharp smack, and you gave a little moan around him, making his eyes blank out for a moment. "Fuck...do that again, doll," he moaned, before slipping his hand under the waistband of your skirt and panties. His fingers dipped into you for a minute before sliding upwards to rub your clit, and you whimpered, still bobbing your head up and down. You weren't worried about being seen- the highway was empty. It was maybe 3:30 am, the sky just starting to lighten.
His fingers weren't as languid and smooth with you as he usually was- but then again, he was trying to drive at the same time, and you were sucking his dick like it was a melting popsicle, one of those red, white, and blue ones that you'd gotten on the Fourth of July, and teased him with by practically deep-throating it in front of him. Billy was utterly lost, already halfway high and deep in his own pleasure.
When I'm like this, you're the one I trust.
You were the only one who got to see the King of Hawkins High like this, and you reveled in it. You loved how you could get him cursing and groaning your name- not unlike the way he was talking right now, a bunch of incoherent moans interspersed with the occasional "fuck!" or "oh, doll" or even the rare "Y/N!" Billy didn't often call you by your name unless he was serious- he preferred to call you "baby" or "doll" or "angel." It made all the girls in Hawkins swoon and wish he was talking to them. He never gave any other girl a nickname anymore- only their name.
Billy's fingers were curling inside you in the perfect way, and your legs were trembling as you felt him tense underneath you. His hips were unconsciously bucking up into your mouth, and you knew that you were both close. His thumb still rubbed your clit in little circles, and you let out one last whimper before your orgasm hit you. You moaned around him, your thighs clenching, and he groaned loudly, arching his back up as he came into your mouth. You leaned over to the side to spit it out onto the road, and looked up at him. His eyes were half-open, and he was panting. When he pulled his fingers out of you, though, he made sure you saw him when he licked them clean. You almost groaned out loud at the sight before settling back into your seat.
"Damn...I don't know how you do it, angel, but you're damn good at it." Billy said, his voice gravelly in that way you loved. You winked at him, your exhaustion from being awake all night slowly starting to win out. "I'm...gonna sleep," you said, your sentence breaking in half as you yawned. Billy chuckled at you as you leaned over, resting your head on his shoulder. "Tired you out, didn't I."
You fell asleep to the lullaby of Billy's music playing on the radio and the open roads.
