It was small, she was worried it wouldn't fit anything - it definitely wouldn't fit any of her. But her insides were insistant, and she was never good at telling them to wait.

She hadn't used one of these before, and she was too embarassed to ask the deliveryman how it was supposed to work. With a cramping groan, her colon made her wrench the door open, yank her pants down, and shove her thick striped backside against the relatively narrow entryway, not even thinking that this strange little miniature bathroom might be occupied...

Her insides were BOILING at this point, her heart racing. It was all she could do not to squeal in bliss as she finally let her anus loosen, letting out a hot puff of air before the solid head of her payload emerged.

It was almost, almost free now. The big, THICK part that was bottling her up. She could feel the looser stuff slip out around it messily, making her push harder in desperate, frustrated desire to finally get it OUT of her. Her body was flush, heated, and she was panting as if a lover were finding her deepest sensitive spots and attacking them with the greatest gusto.

Conscious thought became impossible. Her colon was violently contracting as if giving birth. In a sense, she was. Her canal was clenching, cock throbbing. It was the best kind of orgasm she could ask for.

There was a brief reprieve, when she heard a creak and a THUMP behind her. She held herself shut to look sidewise over one shoulder, a little afraid to see. So much had spilled out so quickly... Her face went an even deeper shade of red than it already was. She knew people must be watching her, she wanted to just pull up her pants, and walk away as quickly as possible, but then...

...Then her bowels reminded her she wasn't done.

Dude is absolutely dead... rip toilet dude
