I went to the proctology clinic for a checkup and ended up being admitted for tests...! Nurse Aki was very kind, but it seems she has a different side at midnight...!? She shoves a suppository containing aphrodisiacs deep into the patient's anus! Then, she thoroughly develops the twitching, sensitive anal and prostate! A dry orgasm—a prostate climax without ejaculation! The slow, sweet, melting pleasure never ends! A "tokoroten" ejaculation that feels dozens of times better than a normal one! The endless sweet pleasure that can only be tasted through the ass, and no-hands ejaculation feels too good...! "Let's turn your ass into a pussy~" Aki's "female-orgasm" development, making me cum sweetly over and over, feels so good...! I can't be discharged for a while...!
