Pee, constipation and frustration

Luna sits on the toilet foretasting a long and satisfying morning session. she takes a long, powerful pee (0:18-1:02) and then begins to push, struggling hard, grinding her teeth and moaning but... nothing comes out! she pushes so hard that after a few minutes the only thing coming out is a second pee!"how many days have i been constipated? oh dear, that's so many days... if i can't get rid of all these brownies today, i'll have to get an enema tomorrow for sure!"she pushes again, but all is futile. her belly is still and stuffed. she wipes herself with toilet paper in extreme frustration!
