WANZ-448 Please have sex with Koyuki's mouth. Yoshiya Koyuki

It's not fellatio. The mouth, with its abnormally heightened sensitivity, has transformed into a sex organ. Inserting it causes one to urinate from the sheer pleasure… At any time and place, it lewdly opens its lips, continuously begging 'Please put it in my mouth,' so you push apart the lips and insert your cock into the mouth, thoroughly enjoying the sensation of the cheek flesh rubbing against the glans. Finally, using the tip of the tongue to grasp the corona, both reach climax… Yes, this is 'sex' with Fruho's 'mouth.'
