To stefan

The act of closing the bathroom door behind an unsuspecting victim without their knowledge until it too late. The victim will then look around confused as you shove them to the ground. You will then "whip it out" and when they say no it will only fuel you to keep going. You will force the partner to lick your dick cheese (disclaimer: only works if penis size is under 2.5" and partner is not above the age of 16) (disclaimer: this is all consensual roleplaying)
