This would be halfway to damn hot if not for all the farting and menstruating. Who else instinctively avoids breathing through the nose when seeing something like this?
I'm pretty sure they're queefing. I don't know why else you would stand with your feet in the air beforehand. Would explain the purported sudden menstruation...trying too hard to push...I'll stop there.
Anyway, I say purported menstruation cause I didn't make it to that scene.
