NFDM-431 A science woman makes a man drink a lot of pee and forcibly ejaculate for sperm research

Description

We, the Chemistry Research Department members at Freedom Gakuen, have recently been researching "the activation of sperm caused by drinking urine". I've been researching day and night to see if there's some kind of relationship to making stronger DNA, but since there aren't many men who can be samples, I'm looking for good-looking prey in the school and peeing. I let her drink and half forcibly collect sperm.
