It's too risky, but you need something. Alex could always pull out...

"Noooo!" you whine. You put the bag down dejectedly. No way you were risking filling yourself with a 1/3 chance of pregnancy and being stuck as a girl forever.

"What's wrong?" Alex asks, continuing to split his attention between the road and your crotch.

"I just really need-" you start, but cut your sentence short. Alex had a penis. Could you trust him to be careful. "C- could you... umm..." you stammer, unsure of the words you were about to say. "If you pull over, could you be careful and make sure you pull out?"

Alex looks at you in happy shock. "I- yeah!" he says enthusiastically. A car honks as it passes, and Alex swerves, returning his attention to the road. "Sorry!" Alex says meekly at the other car. He then addresses you again, his eyes staying on the road this time. "Yes, I can pull out, just let me get to the shoulder!"

He turned on his warning flashers and quickly found his way to the shoulder. No sooner did he have the car in park, and he was kissing you, his hand darting to your bare pussy. You kiss him back, wiggling your hips under the pressure of his hand. It felt great having him rub your clit like that, but just like when it was your own hand, you needed something more. You break the kiss to nod at the back seat and say "Can we...?"

Without answering, Alex hops over the console into the back seat, sitting down behind the drivers seat. As you climb back with him, he's already in the process of removing his pants and underwear. You sit your bare ass next to him and turn so that your legs are toward him and your back is against the door. You lift and part your legs, inviting him to have his way with you.

Alex turns to face you, grabs your hips and slides back toward his end of the car, pulling you with him. You find yourself laying down, with only your head propped up by the rear passenger door. Alex grabs his dick and lines himself up with your entrance. He sinks inside in one smooth thrust. You both hiss out in pleasure as he slides home. He holds himself deep inside of you, his balls resting against your ass.

"Your dick feels amazing!" you moan. You're close. It should only take a few thrusts. You start gyrating your hips against Alex, asking him with your body to continue.

"Your pussy feels great too!" he leans down and takes your mouth into his. The two of you kiss deeply again, Alex not moving from his position deep inside of you. You intensify your hip movements, hoping to drive Alex to start fucking you. At this point, you're practically fucking yourself with his dick.

Alex grabs your hips and breaks the kiss. He holds your hips still, saying "Stop, or you're going to make me cum!"

You stop your hip movements but start giggling. "Really?" you ask, incredulous, "Already?" You giggle again.

As you giggle, the muscles in your pelvis squeeze Alex's dick slightly, but enough to matter. "Fuck!" Alex cries, quickly pulling his dick from your pussy.

"Nooo!" you whine once more as Alex paints your body with cum, sending rope after rope up to meet your belly and breasts. By the time he's done, he's made a thorough mess of your tank top. "Seriously?" you moan in frustration, both at the lack of getting off and the horrible state of your clothes.

Alex flops down on the seat, between your ass and the door on his side. He deflates. "Sorry," Alex says softly. "You just- I don't know- you just had me so turned on..." he let his words trail off.

You sit in silence for a few seconds before you break it. You look away from him in shame as you ask, "If we wait a few minutes, do you think you could go again?"

Alex perks back up a little. "Yeah, I think so," he responds. "We could head back to my pl-"

He's cut off by a knocking on the window behind him. You and Alex nearly jump out of your skin in fright. Neither of you had even noticed anyone approach.
