Just purple and blue, but Lily has other ideas.

"Just give me a blue and a purple, this is what we were looking for." said his aunt. This was pretty much the best scenario that K-T could hope for knowing his aunt.

She let the saleswoman scan her bracelet and received two small strips of paper with a colored dot on each. With how small both the patch and paper were, his aunt was struggling a bit to recover them and apply them to his arm.

"They won't go away if he swims or shower?" she asked, focused on finding the edge of the blue dot with her nail.

"No, no problem with water. **** poured on it will remove it though. It's what we advise to easily remove them." explained the vendor.

While his aunt was busy, K-T caught a glimpse of Lily getting multiple strips of paper from the vendor after whispering something to her.

K-T felt a sharp tinge each time his aunt applied the patches to his arm. The sales pitch was pretty accurate as his dick immediately started to go down once the patch was applied. Satisfied with the results, his aunt was thanking the vendor and trying to figure out how to tip using her bracelet.

But something else was happening. Lily was running her hand on his back in what he assumed was a comforting gesture, until he felt a tinge again once Lily slid the tip of her fingers under the back of his collar. She had applied one patch of maybe more to the only part of his body that was still covered so that his aunt wouldn't notice them, worse K-T had no idea which one they could be.

He wasn't feeling anything special right now after the effects of the first ones were still applying. But he'd imagine that the ones that triggered more important physical changes would need to act slower. He'd have to wait to discover what she had done.

His aunt, appeased by the sight of his flaccid cock, still of an impressive size, decided that it was finally time to enjoy their vacation and she looked like she already knew what she wanted to do.
