Vonka is an old hand at capacity challenges and we already know what she is capable of producing, but Syenite is new to this and therefore an unknown quantity. By her own admission, she has a fairly small bladder compared to Vonka, so she is clearly up against it. The truly entertaining aspect of this video is how desperately Syenite tries to hold her pee in the hope of even coming close to the quantity her friend might produce. She escalates from fidgeting to running in circles as she struggles not to lose control, putting off the release until the last possible moment. Only one graduated cylinder exists these days, so one of the girls pees into the vase. After determining the level in the cylinder contributed by one, they pour the other girl's pee in on top and then perform a simple calculation.

2. I Can't Hold It Much Longer

Syenite has been taken for ransom, and she is kept prisoner handcuffed to a pole while her captor waits for the money to be delivered at the drop off point. Having been restrained for hours, Syenite is getting desperate to pee and asks Vonka, who is guarding her, if she can let her out for a few minutes to use the bathroom. Vonka points out that it is not her problem, and suggests to her prisoner that she hold it. Once the ransom is paid, she says, she can go free and do what she wants. Syenite does her best to wait, but she really is desperate and is continuously pee dancing. She warns Vonka that she can't hold it much longer and begs to be allowed to use the bathroom, but Vonka still refuses to let her go. At last, word arrives that the ransom payment has been made and Vonka sets about unlocking Syenite's cuffs... except she doesn't appear to have the right key. After trying all the ones on her bunch, she goes off in search of other keys, leaving Syenite struggling to wait until she returns. Vonka takes so long that Syenite has no choice but to wet her pants. (In fact, the customer wanted her to get free just in time, pull her jeans and panties down and pee on the floor. We were about two minutes away from freeing her when Syenite lost control. To conclude, Syenite pulls off her wet jeans and panties.
