A camera

Kyra withdraws a rather expensive looking camera, and snaps several pics of you, before quickly removing the sim card, and inserting it into her phone. "Now, all you have to do is get some clear pictures of their little dicklette, and a clear shot of their face, and upload them to the Shrnkr app. Include as much information as you can, in this case we know this man's first name, and the town he lives in, so we can type that in, and hit send..." Kyra then holds up her phone to show the women, "He is logged into the database. Now, if any woman with a subscription to Shrnkr looks him up, they're going to be able to tell that he's got a little nub between his legs before they ever waste their energy."

The women all look very impressed, while you are struck speechless. One of the ladies pipes up with a question. "Can you update entries once their uploaded?"

"Great question!" Kyra says with a smile, as she reaches back into the bag. "If, later, a woman get more specific information, say..." Kyra removes a wooden ruler from the bag. "Exact measurements, which in this case is..." She holds the ruler up to your flaccid cock, as you close your eyes. "One and a half inches." Kyra then punches this information into the app. You try to protest, but she ignores you, and hits update. "Now any woman who looks him up will know that our friend here has a tiny little, one and a half inch dick. This is the future of dating, ladies."

The women excitedly begin downloading the app, as you stand there in utter humiliation.
