Spellcasting 101 - Sorcerers Get All The Girls

From MobyGames:

Spellcasting 101 is the first in a series of risque adventures from the mind of Steve Meretzky of Leather Goddesses of Phobos fame.

This textual liaison pits you as Ernie Eaglebeak, a student at Sorcerer University who finds himself caught in a possible Doomsday situation. Seduce the women and have fun along the way. There are many women with little clothing, although no actual nudity. The game is loaded with college type jokes (eg: Join the famous Tappa Kegga Bru or I Phelta Thi).

The game play was a development of the parser based text adventure typical of the Infocom games but included graphic images that changed as the puzzles were solved and the game progressed.
