I joined a clinical trial job just for the money. Never expected the drug to be an ED treatment! My erection wouldn't stop, and Nurse Kojima kindly watched over me. Despite being a rookie, she skillfully gave me expert blowjobs with relentless tongue action, pushing me to climax even in the middle of the night. Gradually, I couldn't hold back anymore—nor could Kojima. We ended up having creampie sex. This newbie nurse licked me over and over with her tongue, tirelessly working day and night to squeeze out every drop of my cum. Her warm, tender blowjob engulfed me completely, taking me all the way to the base, wrapping her tongue around my glans in indescribable pleasure—making me explode instantly. My thick, milky semen spread inside her mouth, and she smiled as she swallowed it all. This clinical trial job turned out to be absolutely amazing.
