"Crap, crap, crap, crap, crap!" Cursed Karyn under her breath as she hurried over to the bathroom. She swiftly locked the door behind her and stood flat against the wall, listening closely to hear if anybody had heard her enter the house.
Not a noise. Except of course - and curse Jon for this - the faint hissing from inside her jeans.
Speaking of those jeans, they were a mess! You wouldn't see it from the outside, and thank goodness for that. Thanks to that painfully lively protrusion between her legs, the right-leg of her pants became cream-coloured from the inside. Karyn had absolutely no control over that part of her body. When it moved, it did so on its own. And, well... it moved expertly. During the initial swap, she hadn't even noticed she'd taken Jon's trouser snake with her. She just wanted to get rid of the army of bees that began to terrorise her crotch.
Halfway home she finally noticed that the stirring in her groin felt a little more... animated, than it usually did.
It was already too late when the serpent slid out of its musky sheath and went down instead of up her jeans. Needless to say, the fabric didn't stretch well, and as her snake grew bigger, and more animated, it became stuck. The inside of her jeans suddenly became pleasantly restrictive.
But Karyn was outside, and there were still plenty of people walking around in the afternoon on her way home. Just taking off her pants in the middle of the street to grab control over her juvenile dick was sure to bring frowns upon these strangers' faces. No amount of swapping with the Role Exchanger could resolve that issue. At least not during that moment.
Swapping her legs with somebody else again meant that Jon's legs could end up lost in the crowd. Even when she was angry at him, Karyn wouldn't do that to Jon. Not on purpose at least.
No. She would just have to grin and bear it.
Every next step her legs grew a little weaker.
She felt her nipples grow erect. Her balls - she rediscovered that she had them right now - were throbbing inside her panti- inside her boxer briefs.
Anybody passing by could easily see how aroused she was, not by her own will. There may have been some nasty looks, but most people just glanced past her, ignoring her struggles.
At some point, Karyn couldn't bear it any longer. She entered a small alleyway - something she'd normally never do - and crouched against the brick wall of a building hidden from view behind a dumpster. In that place and time, she felt like a degenerate pervert. Her cheeks were flushed with shame, her libido skyhigh. She carefully stroked her rod where it was coiled around her thigh. She felt it constrict her leg, strongly enough that her foot began to tingle and fall asleep.
And now, fifteen minutes later, experiencing post-orgasmic clarity - remarkably not for the first time that week - Karyn bore witness to the consequences of her escapade.
Her trouser snake, finally out of its confines, was hardly awake anymore. Rubbing it now earned Karyn a hiss in protest, the snake too sensitive to want to go a second round. Sticky white drool still outlined the corners of its maw from where it came.
Karyn's right leg, now a lot hairier than she was used to, was covered with strands and threads of boy-jizz. A shower was mandatory. The teenage 'girl' didn't want her parents to see this. It would be embarrassing for her, even with the power of the Role Exchanger on her side. She would have to have a long think about whether she wanted to keep this pet snake or not.
And mull over it she would. Her partner in crime writhed in anticipation.
