Mercy's Duty (6 Pictures - Commission) (Patreon)

It is Mercy's duty to take care of her test subjects no matter how massive they end up. Even though she might have go overboard with Ashe as the girl overdosed on a mix, outgrowing her lab entirely before Mercy took a few doses too to catch up! What Mercy did not expected was that Ashe has some swelling tastes on pumping the poor doctor with lakes worth right into her balls!
