Mindy woke up first, still reeling from the hours of sexual ecstasy the night before had brought. She looked over at Mark, still snoring next to her. Flaccid, his penis gave little hint of its immense erect size. He looked so small next to her. She was used to that by now, but it never failed to excite her. She stretched her legs, her feet shooting out past the edge of the bed, and laughed to herself. She thought about her sister, about how her size had made her a fortune, how it had bought this massive bed... but not massive enough for her "little" sister Mindy. She wondered how much taller she'd grow. She seemed to be getting bigger by the month... and considering that she'd grown seven inches in the past year, she hardly seemed to be slowing down. A year ago, she looked up at her sister. Now, she towered over her, with no end in sight. It gave her an intense thrill.
When Mark woke up, he could hear Mindy in the shower. But that's not what woke him up. It was a clicking sound. The front door.
"Honey?" Mark's heart sank. It was Kathy!
She entered the bedroom, looking absolutely radiant in a cute blue dress that barely contained her huge breasts. But her smile disappeared almost instantly as she entered the room. There was no mistaking what had gone on the night before. "Mark...?" she asked, the rest of the question simply implied.
"Kathy!" Mark blurted, desperately. "It's not... you don't...!"
Quickly, her sadness turned to anger.
"Who is she?!" she demanded. Mark had never seen Kathy like this, and the thought of this giant, incredibly strong woman enraged was a bit scary. There was no telling what she was capable of. She pounded her fist against the wall, and the paintings shook precipitously.
"That you, Mark?" a voice asked from the bathroom. The bathroom door opened, and out ducked Mindy, still damp and completely naked. It was hard to tell who was more startled to see the other, Mindy or Kathy. Mindy stood up. Even in her bare feet, she stood a good three inches taller than Kathy.
Kathy lifted her hand to slap her sister, but Mindy was too quick and grabbed Kathy's wrist. Mindy instinctively raised her other hand, but Kathy grabbed that one. They wrestled for a few moments.
Mark stood up on the bed, yelling "Stop it! Stop!" But his cock, which was slowly stretching longer, suggested otherwise.
Kathy slipped one of her long legs around one of her sister's, tripping her onto the bed, with Kathy on top. Mark jumped out of the way just in time to avoid being crushed under them. They spun around, back and forth. First Kathy was on top, then Mindy, then Kathy. Finally, Kathy got Mindy pinned down against the bed. But she was no longer angry. In fact, she was laughing. Mindy started to laugh, too. Mark could hardly believe it. They were like two little girls, except they were very, very big.
"I'm sorry," Mindy said. "After all you'd told me about him, I had to get it out of my system. If it means anything, he had no choice in the matter."
"I'm sure he didn't," Kathy giggled. They both looked over at Mark, who was staring, his massive erection throbbing to full size, pointing straight at them.
Kathy looked at Mindy. "I'll make you a deal. Tonight, you and I share the wealth, as they say. It'll be all three of us, until the morning. And then it's hands off, forever."
"Deal!" Mindy replied, and they shook on it.
Kathy looked at Mark, unstrapping her dress and letting her spectacular breasts free. "What do you say, honey? Think you're up for a combined sixteen feet of pure woman?"
Mark just smiled and dove onto the bed, between their two enormous, warm bodies. He felt tiny as Mindy rubbed her breasts and body all up and down his back, while Kathy rested his cock in her considerable cleavage. Mark was in heaven. And soon, so were the towering Watters sisters.

Mindy was true to her word. The next time Mark saw her was at his wedding to Kathy, nearly two years later. She now stood a mind-boggling 8'10" tall, and thought she still had an inch or two of growing to do. She brought her new boyfriend, a nice enough guy named Frank who, at about 6'6", was huge by any other standards. Word was that his endowments put even Mark to shame... but that's another story.
Kathy wore a white dress cut low on top to reveal her astounding cleavage and high at the bottom to show off her incredibly long legs. When Mark was told he could kiss the bride, there were laughs as Kathy leaned way down to allow it, then gasps as she effortlessly lifted him two feet off the ground so that they could kiss on her level. Mark's penis grew in his pants, pushing very visibly against the side of his left pant leg, much to the amazement of the guests. But Mark didn't care. He just kissed his new, giant wife, literally walking on air.
