You looked at your watch. You had 4 more hours in the car. 4 more agonizing hours you had to wait until you could sneak Jack into your room. He’d fuck you against the door, like he was hoping to wake Sam or Dean up with the noise you two would make. The walls of the bunker were thick, but they weren’t sound proof. Dean slept with headphones on, but Sam must have heard something.
Sam had tasked you with teaching Jack what Sam called ‘human stuff,’ and the two of you had found ‘human stuff’ to mean a lot of things. You taught him about everything from world history to table manners and manners in general, and eventually he started asking questions about sex. He started asking if he could have sex with you. You tried to explain to him that sex is something you do with someone you really, really like and who you’re physically attracted to. But he knew you were just saying that. You were using those manners you had taught him about. He could feel your attraction to him, he could sense it, he could smell it, he could taste it in the air, he could feel it with his angelic senses, teasing at the core of his being. He felt the same way, too.
“I don’t think I can wait until we’re in the bunker,” you texted him. Jack was sitting right beside you, but you didn’t want Sam or Dean to hear your conversation. You resisted the urge to simply pray to him and hope the grace inside him could pick it up, as other angels might hear you. He smiled slightly at your text.
Your phone lit up. “Maybe we won’t have to,” he wrote back.
“I’d love you to fuck me right here, in Dean’s car,” you replied, biting your lip. “It would be so hot, wouldn’t it?” You knew Jack liked risky sex, and the thrill of possibly getting caught. You hitched up the skirt of the FBI suit you were wearing for the case you were on, revealing the skin above your thigh highs. “I miss feeling you inside me. Want you so bad right now.”
Jack swallowed hard and took his jacket off, laying it in a heap on his lap to hide what was happening to him. It wasn’t much use as he was blushing and obviously turned on by something he was looking at on his phone screen.
Sam cleared his throat, noticing the unmistakable feeling of sexual tension and desperation coming from the backseat. Dean turned the radio up louder, vaguely weirded out by Sam’s sudden discomfort but oblivious to what was going on between you and Jack.
You saw Jack wave his hand in the direction of the car’s gas tank. The suddenly needle went a lot closer to empty. You smiled at him and he smirked back.
“Uh, hey, looks like we have to refuel pretty soon,” Sam said to Dean.
“What the hell?! We just filled up a few hours ago. Well, whatever, it’ll be good to stretch my legs and get some fresh air,” Dean said.
About a half mile later you found a gas-n-sip. Sam got out to stretch, and Dean got out to refuel. There was a small diner attached to the gas station. You had no interest in food, but you were sure Dean would drag you all in there for an awkward dinner, when all you and Jack could think about was sex.
“What do you say after I fill up Baby we all go fill up on some pie?” Dean suggested.
“Uh, sure,” Sam said. “You guys want anything?” he looked back at the two of you, a knowing look in his eyes. Sam had figured it out and was giving you the opportunity to say no.
“I’m not feeling hungry,” Jack said.
“I think I’d like to just stay here and get some rest,” you said, faking a yawn.
“Suit yourselves,” Dean said, and after he parked the Impala behind the station, the two of them walked away and into the the diner.
You both sighed in relief, right before Jack pounced on you, your lips meeting his in an unrestrained kiss. You wrapped your legs around him and moaned as he ground his hardness into you, kissing your neck. His hand made its way under your shirt and under your bra, freeing your breast so he could fondle it. Dry humping and making out, you weren’t sure you had time for anything else. It felt so good but you both wanted more. “Jack..” you panted. He stopped and his eyes met yours. “Please.. I want you, now,” you moaned. You reached down and unbuttoned his pants.
