Cast an arouse spell
From Create Your Own Story
You decide to devote a chunk of your magic to arouse the goblin, so that he will be less likely to attack you again. You open your right hand toward the ground and point your left hand at the goblin's head, with your fingers extended. You focus your energy to bombard his mind with images and thoughts of yourself. He is struck by visions of your naked body pressed against him. Kissing him. Touching him. Licking him. When it is over, you see him looking you up and down. His green dick is now lifting his loincloth. You marvel at your well cast arouse. The goblin starts stroking his cock while looking at you.
You can barely contain yourself in your current state. You lie down and spread your legs. The goblin eagerly walks up to you.
