Spank 18

This is an interactive 3D flash game that places you as a high school teacher in an all-girls academy. The classroom is filled with all manner of hot girls and it is up to you to warn and spank them to keep them in there. In other words, you have to police them to catch them with cigarettes, chatting, masturbating, cheating, sleeping, etc. If you succeed, you get to take full advantage of them across multiple scenes involving a lot of cowgirl, missionary, and even doggystyle sex. Just be sure to read the instructions carefully if you want to navigate your way through the gameplay easily.
