D&D: You use a spell to knock him out
From Create Your Own Story
You look down at the hand holding you and smile. For this spell you just need direct contact. That's gonna be easy. You whisper a few words of arcane power and a ghastly energy creep out of your arm and into his. He immediately stop dead in his track and let you go. You let him fall face first into the ground.
"That's what you get you dirty pervert."
You take your time to pick up your things and clean your mouth and face before making your way towards the merchant district.
The encounter has made you horny but you try to push back your sexual frustration elsewhere. As you walk, you find yourself passing through a street in the slums. As you get into the maze of alleys you find the entrance of the merchant's district. Ahead you see two man blocking the path to the merchant's streets and you see another man getting shoved away.
"No money, no passage. This is our street and you need to pay the toll if you want to go through."
You recognize the general behavior of thiefs' guild men.
As you approach they look at you: "You want to get through? it's gonna be 10 silver."
You ponder your options for a second. You could try another path but these thieves tends to be well organized. As you are thinking, you can feel the tingling in your crotch and fear it might affect your decision.
