Nursing

Johnny used the magical computer program on his laptop to give his sexy nursing student neighbors big breasts and an even bigger fetish for giving titty fucks, especially to him, and he paid them by giving them sexy outfits to wear while they milked his cock for the cum they desperately needed on their tits.

Johnny wasn't evil, the girls were still straight A students, but the only thing they loved more than schooling was cum on their tits, and Johnny was their favorite source.
