Getting down with it

"Get naked, and get on here now," John said forcefully, releasing her body and shoving down his pants, completely freeing his dick, which stood proudly before him.

Zoe quickly reached up and down, ripping off her own clothes in only a few movements. Running her hands down her front, brushing across her breasts, she reached down and spread her lower lips, positioning herself over John's throbbing erection, and sank down slowly, moaning ecstatically. Unable to take all of him in one go, she lifted back up until just the tip was inside, then dropped back down, moaning as she took more and more in. John was not idle, thrusting up to meet her, and reaching up to fondle her boobs as she bounced on him. Fucking her felt so good. That she was his sister never crossed his mind as anything important.

"C'mon, fuck me sis," John moaned, thrusting up hard into her cunt and mauling her tits. Zoe's actions began to get more frantic, as she finally got all of John's member inside. She writhed around on him, varying the angle and speed, attacking his dick, moaning and purring out her pleasure. His hands wandered all over her body, and hers on his, rubbing and caressing every inch for maximum stimulation.

John and Zoe continued fucking for quite some time, John pumping her enthusiastic body for awhile, the switching positions so that she was above him controlling the action. John came in her repeatedly, his cock never flagging, her enthusiasm only increasing with her orgasm count.

John felt another climax rising. For some reason he couldn't quite discern, he suddenly decided to pull out of his excited sister, yelling at her to swallow it, to take it all, which she did immediately, turning around and taking his cock into her mouth, the sensation of her lips around his penis pushing him over the edge. John came hard into her throat, pouring his seed down into her stomach, as she desperately tried to swallow fast enough, orgasming herself while sucking on his spraying dick.

As John's climax wore down, Zoe stood up, licking her lips. John lay back on the wall taking in the afterglow.

"Ok, bro, so next time you'll watch where you're going, right?" Zoe asked in a husky voice. "I have to get going, or I'll be late." She stood up, and started down the stairs, unconcerned with her disheveled, naked appearance. As she walked down, her hair gradually went from mussed to combed, then to styled. The sweat on her body vanished, as did the massive splooge puddle between her legs. As John watched, A pair of bra straps appeared over her shoulders, snaking around and suddenly splitting, one pair meeting at the small of her back and the other looping around the other way to join up with a strip of black coming from the front. A similar event took place down below, a strip of fabric appearing from between her legs, snaking up through her butt, then dividing and meeting up with a pair coming around her sides from the front, a pair of black flowers forming where they intersected. The air around her solidified, although just barely, leaving her suddenly clad in a nearly transparent black knee-length dress, a large cutout showing plenty of back. As she stepped off the staircase, her 5" heeled leather boots clacking softly, she looked more like she had just walked out a gothic salon than a hot fuck session. She turned and waved to John, showing that the front was slit all the way down to her navel, barely held closed over her massive breasts by another flower, and headed out the door.

She never had made it to her room, yet she had a black handbag slung over her shoulder when she left.

John lay there, slightly stunned, not noticing that he was now dressed in a tight tank-top and shorts. 'Now that was a wish,' was all he could think of.
