Stoney slowly withdrew until just the head of his prick was still being clasped by her pussy, then pushed inside her again. Her pussy was tight, gripping his whole length, and he was trying to savor every moment, but she was having none of it. "Don't play around: give it to me! I want you to fuck me, Stoney! " His sister moved her hips jerkily back and forth, encouraging him to speed up.
As he picked up speed, he became drawn into the sensation, pounding away at her, staring down at his cock appearing and disappearing, her ass cheeks quivering.
Nicole felt her orgasm building. As he hammered her, she screamed "OH, YES! God, that is GOOD! Take me, Stoney! Take me, fill me, make me yours! God, I LOVE IT!" Her whole body spasmed as she came yet again, this one the best one yet. "Yes!YES! AAAAARRRRRGGGHH!"
Her pussy pulsed with her orgasm, and the sensation sent Stoney over the edge as well. He added his voice to hers, echoing off the bathroom walls "Oh, God, Yes! URRRGH!" Despite having already cum earlier, he produced several massive gouts of sperm, bathing her cervix with the hot ejaculate. As he continued to thrust into her, their combined juices were whipped into a froth, washed away by the warm shower as it dripped out of her, around his shaft.

Ann organized her day's work quickly, and set the parameters so her assistant could finish the processing. She was determined to get out early, and sure enough, by noon, she was climbing into her car to head home. She hummed happily as she drove, thinking of how surprised Stoney would be that she came home early to spend the afternoon with her son. He had been gone almost a full year, and had grown into a man while he was away, but she was sure he would still love to spend time with his mother.
Ann never would have admitted it, even to herself, but seeing his muscular naked body the night before, as he struggled to get up from his fall in the bathroom, had awakened a desire in her. She told herself that she just wanted to spend some quality time with her son, who would only be home for a couple of weeks, but deep down, she hoped he would be working out or lounging around in just his shorts when she got there, so she could feast her eyes on his hard body. Just looking, of course. Those fantasies she acted out with George, those were just fantasies. She'd never actually DO anything with her son. It was just the idea... and that idea had her soaking her panties as she drove.
When she pulled up to the house, though, Nicole's car was in the driveway. Ann experienced a moment of disappointment, but then reminded herself that she hadn't REALLY intended to do anything more than spend time catching up with Stoney, listening to his army stories. It made perfect sense that Nicole probably did had the same idea. Of course Nicole would have skipped a class or two to spend some time with her big brother while he was home. They were always close growing up, and she'd want to hear all about his exploits.
Ann parked in the drive instead of pulling into the garage, since the day was so sunny and pleasant. She didn't think about the fact that the noise of the garage door might have announced her presence, while quietly going in the front door kept her arrival unnoticed. She hung her keys on the hook by the door, and was just about to call out to her children that she was home, when she heard the unmistakable sounds of two people in the throes of passion drifting down the hallway that led to the bathroom and bedrooms.
Curious, she walked quietly down the hall, to the bathroom, where Nicole and Stoney had carelessly left the door wide open. Her gaze took it all in... the clothing scattered across the floor, the steam misting the shower door while not quite hiding the youthful forms engaged in a shameless act of incest. "Take me Stoney! Take me, fill me, make me yours!" No doubt about it, both of her children were completely into the taboo act they were performing.
Ann watched, entranced, until they were obviously winding down from their orgasms, then she tiptoed back to the front door, and opened it before shouting "Kids! I'm home early! Anyone want to do lunch with me?" and loudly closing the door behind her and stepping back into the living room.
