Since we ended up at an ordinary love hotel, the bathroom is so cramped and inconvenient... The tight space means there's no room to stand or squat, and movement is extremely limited... So my only option is to stay inside the bathtub... Which leaves me no choice but to administer an enema... Truth is, I'm just suffering from lower back pain... Since this is my first time doing this, let's proceed carefully and see how it goes... Here we go... "Hai..." Is it a bit hot? As I insert the 300ml glass syringe into her anus... "Hai... daijoubu... atsu... ah... it's not hot..." Is she nervous? The temperature isn't particularly high, but maybe she mistook the sensation for heat... She's such a troublesome one... Annoyed, I suddenly squirt the warm water from the syringe deep inside... "Euu... euu..." Overwhelmed by the pressure in her rectum, she can't breathe properly... Seems like there's no serious issue, so I forcefully inject the rest of the water all at once...
