A simple patch

"This place makes so much from this kind of tourism that they invest a lot in cutting edge technologies related to their specialties. This nice lady sells some patches you put on your skin, like for people who want to stop smoking and each of them has a particular effect. They have no side effects and act pretty quickly." explained Lily.

As impressed as K-T was with the description of some almost sci-fi tech he really did not want to become a Guinea pig for Lily and his aunt. The patches were little pasties of bright colors, barely the size of a one cent coin, sold in ribbons of paper with lines of dots that the vendor ripped for the required amount.

"That sounds wonderful, but do they have anything that would help with our problem?" asked Jill.

"Of course mam, we have all the things. Patches are good for a full week, effects fade within 12h to a day if you remove it. Green patch he'll be hard as rock, white patch he will cum gallons, red patch his thing will grow to nearly twice as big, purple he won't get it up, pink he'll shrink to a third or a fourth and blue he won't cum at all. We also have some for the ladies, express diet, bigger melons, smaller ones, same for the buttocks, tighter or looser in various places. So, what are you ladies in for? " explained the vendor.

K-T was horrified by some of the effects, even if he didn't like having it so much in view, he was pretty proud of the size of his dick. Not being able to be hard until he got the cuffs off was looking like a necessary evil if it could calm his aunt.

"Is there any issues using multiple ones?" asked his aunt.

"Multiple of the same you get barely more, maybe half over the effects of one maximum. Different ones that are not opposites, no problems. Opposites don't cancel each other well, weird effects, not dangerous, not advised." explained the saleswoman.
