Been busy! Any chance for a little ... incest?” Karen whispered in my ear now.“When I’ve recovered, sure. Why not? I see that you’re a heathen...like me now,” I winked at my sister as she licked her lips and then fed me from the tray.“Mmm ... Stacey would be so jealous of that tray right now!” Amber commented.“That is so true. She’d be green with envy!” Katie snickered as Karen planted a lip lock on both ladies.“I don’t know who Stacey is, or what that’s about, but I can tell you guys this much.. Growing? She was! The class watched as she grew taller and taller. Her skirt rode up her tighs. Her shirt stretched, buttons straining. No one was more shocked then Janet.Then, her shirt could take no more. POP POP POP! The buttons on her blouse shot off in all directions. Her shirt fell open, revealing a black, thick bra. Her skirt split down the side, flapping loosely. And still she grew. She was nearing six feet tall now! Her shoes split apart, bare feet ripping through them. Her waist. "Just drive. I know what I'm doing."Ryan nervously turned the car back on and began to drive slowly. He kept his eyes on the road but could feel his sister massaging his hard on. Her hand slowly crept into his sweat pants and pulled out his throbbing dick. "Mmm I can't believe it was just yesterday that I lost my virginity to this nice cock," Natalie whispered.Ryan scoffed nervously trying to keep his eyes on the road. He felt his sister grab his cock in her hand and that was it. He sighed,. ”I headed back inside the house and went to the kitchen where I expected they would be, but they weren’t. I started to walk around the house quietly thinking that maybe they were playing another trick on me. I thought I heard something from upstairs, but then it was gone. When I heard it the second time I headed upstairs to check it out.I peered into Lisa’s room as it was halfway open and that’s where the noise was coming from. When I looked in I couldn’t believe my eyes. There was Brian.
