Magic. Figuratively speaking, of course.

"Alright, done. Look into the mirror, slutboy."

Adam did not believe his eyes. His sister had managed to make his male face sexy and alluring. He ha no idea how, it didn't even really look like he was wearing make-up, but he definitely would have wanted to ask himself out. Or rather a girl that looked like him. He wasn't quite sure if that made sense, but before he could continue the train of thought, his sister shoved something in his hands.

"I can't do anything about that hair, but we can at least make it a bit... cuter," Sarah said, the mischievous grin back on her face.

Adam took the headband, complete with a little bow and put it on, his sister fussing with his hair a bit afterwards. Looking back in the mirror, he saw a big-titted girl with a weirdly short haircut - but a girl nonetheless. Suddenly, he was a lot less apprehensive about going out. Before, he had been a guy with big tits. He had almost been able to feel the judging stares of the other shoppers, but looking like this, no one would look twice. Adam wasn't quite sure if he should be happy about the situation, but his sister didn't give him much more time to think.

"Alright, we're good to go, slutboy. Let's roll!"

En route to the mall in Sarah's car, Adam noticed that she was still throbbing and close to busting out of her jeans. His sister on the other hand could not keep herself from stealing glances at the way his bra-less boobs jiggled with every bump in the road. Stopping at a red light, she smiled seductively at him and moved one hand to her crotch. Adam gulped, his mouth watering with the thought of the huge meatstick about to be unleashed. Sarah opened her fly and actually had to raise her butt a little to fish her pulsing cock out. It sprang to attention immediately, almost hitting the steering wheel, vibrating with every heartbeat.

"You know what I want and I know you can't-"

Before she could finish, Adam had already leaned over and crammed the head into his mouth, moaning happily and licking her glans. Sarah breathed in sharply and missed the light turning green, only stepping on the gas after the car behind them honked in frustration.

The vibrations of the car traveled up Sarah's dick and tickled Adam's glossy lips as he started to bob his head up and down softly. While he definitely needed the heavenly jizz stored in his sisters plump balls, he was lucid enough to avoid deep-throating her cock. He wasn't _that _into her dick. However, Sarah was intent on using the road to help things along. A small pothole suited her needs just fine.

Driving over it, her dick shot into Adam's mouth and made him gag quite a bit. She took one hand from the steering wheel and put it on the back of his head to direct him to take it deeper. The pre-cum pooling from her slit filled Adam's nose with the smell he knew and loved. Quickly, he started feeling dizzy and soon deep-throated his sisters twitching cock without any encouragement, small glrk-sounds filling the car along with Adam's muffled moans and Sarah's gasps at her brother's surprisingly adept cocksucking.

Stopping at another red light, Sarah was a little amazed that she was still able to drive halfway safely. She looked into the back mirror and she noticed how obviously aroused she was, with her mouth hanging open and her cheeks flushed. A fact that the guys in the car next to her obviously noticed, if their hooting and hollering was anything to go by. One in the backseat gave her a thumbs-up and yelled:

"Yeah, baby, get that pussy licked! Equality roadhead, bitch!"

Sarah couldn't help but grin. If only they knew what was really going on. A particularly strong bout of suction from her brother made her suck in a breath through clenched teeth and turn her head forwards, where she noticed the light turning green. The guys in the other car sped off honking while she drove on at a much more sedate pace, feeling her pleasure mounting. Adam turned from bobbing up and down as far as he would go to sucking at her swollen helmet, letting his tongue play over it and stroking her shaft with one hand, having realized from the frenzied Ah's of his sister that she was about to unload.

Sarah stopped at the roadside, afraid of crashing the car if she continued driving and drove her surprised brother's face down into her crotch as far as it would go as her urethra widened. Adam's eyes first widened and then rolled up in pleasure as the first shot hit the back of his throat, followed by a second and a third.

"FFFFUCK, yes, swallow it all!" Sarah yelled, bucking her hips upwards into her brother's mouth until her balls emptied. Since she had cum several times already, the amount was quite diminished, but she did not want to clean up cum-stains from her carpet.

Adam gulped down every glob and sucked and lapped on his sister's softening pole until it was clean. As he sat back up, a dopey grin spread over his face. All was well, he had made his sister cum hard, she had given him the cum he craved and now they would drive on to the mall. Who knew what would happen?
