Let's keep some sense of realism

Tom decides to keep it somewhat realistic, nothing too crazy, but that still leaves alot of options... What to choose, what to choose.

He could decide for her to have a long dick, Tom was quite proud of his own size, being above average, and Sarah had certainly been enjoying it alot lately, but he was unsure if he should give her that, or leave her with something so small that it is easily hidden. Not to mention if he did give her a large member, that would be a problem, though now that Tom thought about it, it wouldn't be too hard considering what the coin had already done.

Yes, if she is to have a long one, Sarah should probably be able to hide it so that she doesn't get in trouble at work, they didnt need that. So he wittled it down to a few choices, have a mega shlong that while we are keeping some sence of realism, is way oversized to be normal, even by alot of porn standards, average sized, or a tiny one that could be barely made out. It was tough, when you have the power to do this much the burden of choice was certainly great.
