Josh wakes upp first

The next morning Josh woke up way too early thanks to his nap yesterday, and waking up to the sight of his sister got him far too excited to even consider going back to sleep. Plus seeing her cock lump in the blanket immediately stimulated his thoughts of growing her bigger. Thoughts that weren’t going away once manifested. He debated with himself if it were even ethical to grow her bigger, as it would do nothing but complicate her life. But then again, she didn’t seem to want anything more than to grow bigger, outside of Josh’s attention. He didn’t have a doubt in his mind that nomatter how many obstacles arise from her size, she would be happy as long as she remained at least as sexy as she was now. Or maybe he was just trying to rationalize an excuse for him to satisfy his sexual fantasies. As he debated with himself he was staring at the long penis shaped lump in the blanket over Liz’s abdomen and noticed it hardening. Josh looked to his sister’s face and her eyes were still closed, as he returned focus on her dick, which looked to be about 16 inches long now and growing. He stared in amazement as the blanket lifted higher and higher, cresting at just higher than 1 and a half feet high. He was hypnotized with it, then it bounced back and forth a few time, Josh quickly looked at his sister’s face, her eyes were closed, but she was clearly holding back a smile. “Liz, stop, I know you’re awake.” Liz’s face grew a large grin and her eyes opened.

“Oh! I’m so embarrassed! Ever since I got this thing this has been happening every morning! And its gets worse and worse every day!” Liz both teased but seemed at least partially curious. “Yours does it too!” she said pointing at Josh’s erection, “But maybe you just accidentally snuck a peek at your sister huh Joshy?!” She looked hopefully at him.

“Its called morning wood Liz, its something you’ll have to get used to unless we can figure out a way to fix you.” Josh responded trying to stay away from getting playful, but saw a look of understanding on his sister’s face “I know it will be tempting Liz, but you are going to have to resist being seduced into… relieving that, until we know what is going on with you. Besides we won’t have anything to dress you in soon!” Liz looked a little disappointed, then nervous. She wasn’t sure she wanted to reverse this, but knew life is going to be hard staying this way. Then she looked playfully at Josh.

“Oh I don’t worry about that, I told you I won’t be touching this anymore, the only person I’m letting do that is you ‘little brother’.” She said it like a challenge, and Josh began to persperate at the pressure, “If I get any bigger it won’t be my fault.” She smiled.

“Er, good, well lets get dressed and get ready to go, we have to be at Dr. Klapper’s office in 2 hours” Josh said quickly then began leaving the room, “go ahead and take what you need from my room to get dressed.” He said as he left his sister’s room naked.

Liz sat up and stretched her arms above her head, her large biceps lightly touching her head, this lifted her breasts higher and caused the sheet to fall off it. Her breasts, despite being as large as basketballs, were perfectly firm, and pointed slightly up. They pointed even further up while she was stretching and was now able to touch her chin to her breasts if she lowered her head down to it. She kissed the top of each breasts and got up, dragging her blanket with her caught on her cock. She stood up at full staff, and pulled the blanket off. It looked so tempting, and she was very horny, but she made a promise to only let Josh grow her. This not only was meant to seduce him into validating her growth, but she also figured he really really got turned on by helping her grow. And though that is true, she didn’t know that for Josh’s fantasy, he liked her big, but liked seeing her grow even more. He isn’t into a giantess as huge as a skyscraper, but he would love to see her grow that big. So with this need to see her grow, it might compromise his judgment, and cause him to grow her much larger than he wants. But for now she was content. She needed to get off though somehow, and with her penis off limits that only left two options: and even though she was tempted to jerk her nipples, she chose to give her poor forgotten vagina some attention. She was still after all a girl, and decided it was time she knew what it felt like to be pleasured as one. Eye-ing the room she focused in on a baseball bat, and knew what to do.

While Josh was showering he could hear the moans and screams of his sister from across the hallway. “Uh oh” he thought as he finished up and turned off the water and stepped out. As he toweled off he heard one large scream and prepared himself for what would be waiting for him out there.

Liz was amazed. After she orgasmed, she felt much calmer, yet had more energy. The climax felt much different than anything else she had felt, and in some ways was better. It took a bit more work, but she knew now that she would have no problem resisting her penis, which now had gone limp. But while orgasm made her penis useless, she found she could still feel incredible sensations from the bat as she twisted it in her hand. Man if only she could get a real cock in her… stupid brother and his morals. She started sliding the bat in and out again.

Josh slowly opened the door expecting the worst, especially when he started hearing his sister moan again. Peering out he saw her door was closed mostly, and decided to end this before it got outta hand. He walked to her door and opened it wide. “What’re you doing?!” He asked accusatory, but instead of seeing a ridiculous giantess Liz stroking her cock, he instead saw his previously amazon sized sister thrusting the handle of a baseball bat into her under her balls. “Oh s’sorry” he stopped.

“I-Its okay Josh, you you just wanted to make sure I didn’t take away whats yoursssss… “ She continued to masturbate “Is the shower opennnnnn” She moaned.

“Yeah… uh sure Liz all yours.” Josh backed out of the room, closing the door. He went to his room to get dressed when he heard her second orgasm. Moments later heavy footsteps lead into the bathroom then the door shut. Josh breathed a heavy sigh, finished dressing then went downstairs for some breakfast.
