a bit of both

Panting, Alex decided fuck it, I've got to commit to something!

So pressing the pen to his flesh, he grinned.

Permanent 10'' cock

Suddenly the dick he was pumping with his other hand swelled, far surpassing anything he'd even seen in porn as it filled his hands.

Pumping it while a feminine keening sound escaped his throat, he came, covering the stall wall with his cum before he gasped, watching his mighty pecker slowly wilt.

Settling at an impressive 4 inches soft, he noted that it was still fairly thin.

Taking out the marker, he made another mark.

Permanent Thick cock

He bit his lip to keep from releasing another moan as his tool thickened. But he didn't get erect.

He'd never had very good stamina. If he managed to get himself hard again all he'd be able to release is a little spurt too.

Permanent super productive balls, permanent excellent stamina.

Alex, giddy with the rapid changes, forcibly calmed himself as he realized he'd just made 4 permanent changes to himself without even thinking about it.

He got up, cleaning himself off as best he could while studiously ignoring his now virile cock stiffening from the action. He needed time to think before implementing more changes.

Storing the Marker in his pocket once he was finished, Alex made his way out of the mall swiftly, using the time it would take him to get home to think about things.

Adventurous was still on him, so creeping thoughts of dicks and submitting still made their way into his head. It was kind of surprising just how focused he was on that.

By the time he made it home, Alex decided he'd at least test things out both ways. No need to give up women, but guys...

Well, he was still kind of picky on them.

But even so! He'd been mistaken for a girl all his life. It was now or never. Become more manly, or embrace becoming a femboy, if a big dicked one.
