Nothing to worry about

Your sister was not the prettiest girl. She had mousy brown hair and crooked teeth. Her glasses were as thick as cork and her grey, most often tired eyes, behind them,ade her look like a giant fish out of water. You would not even start thinking of her body. Aside from acne all over her skin and some misplaced thick body hair on her arms and legs gave you a shudder.

You heard her walk down the floor, almost thinking. You could bet she wanted to get the image of you, naked, ejaculating on your mirror image out of her head as quickly as possible. Your eyes wandered to the typewriter.

Of course I could just make her forget about it... Then again, where would the fun in that be, You thought. Once again you took place. Your softening dick ached a bit as it rose once more at the thought of what you wanted to do.

My sister is feeling an unnatural arousal from having seen me naked.

You grinned. Your sister was an eyesore. That was for sure. Yet somehow, thinking about her being attracted to you, although it not being mutual felt erotic.

Now you pondered. Your sister was most likely attracted to you now, despite your little... Disadvantage. You looked down. Your little friend was up and rising. Why not give it a little growth spurt?

Eagerly your fingers typed away.

My penis will grow to be as long as my thigh.

Immediately you felt it. As if being pulled by soft hands your penis extended lower. Like a string it extended downwards. Finally as the feeling of being stretched subsidized, you stood up.

Unfortunately it seemed, that your command on the typewriter was not very clear, as it seemed that only the length increased. The thickness was the same and now your dick hung there like a snake waiting for being called upon by a charmers flute. "This is... Interesting" You chuckled and wailed your extended organ around a bit. You jumped, watching as your penis flew with your body. "Funny, but not what I wanted"

Your left hand grabbed around your dick. The long noodle felt weird, yet better than the small toothpick you had before. With your right hand you wrote a new paragraph.

My dick will thicken to a diameter to only barely fit in my hand.

Your dick grew in your hand. You could not resist stroking it as your writing took effect. Your soft skin gave easily in to your own touch and quickly blood filled it, hardening it.

Once again you stood up. "Now that is more like it" you said, examining yourself. Your mirror image had a wide grin in its face. The thick batoon in its hand seemingly possible to be able to kill a person, if struck with. You played with your tip.

You almost began masturbating again, but you managed to restrain yourself. This is not what you planned to do. Once more you sat down. The exotic and pleasurable feeling of your thick dick between your legs shoved aside, ,you searched for the right words to write next.

My sister has a body that would be widely seen as attractive and visually pleasing.

There. That should be it. Suddenly you heard screaming down the hall. And there it is. Your strong hands slapped against your head. If you noticed the changes made by the typewriter, why should not everybody else. You sighed heavily and wrote on.

As far as my sister and everybody except me is concerned, they will think, she had always had that body.

The screaming went away. "Phew"
