It takes effect

Helga finished her meal and then started breathing heavily. She started to sweat and looked at Kazex strangely. "Excuse me, servant. I need to......do something. Clean up here." She said as she went to her bedroom hastily and shut the door.

Kazex smiled knowing that the potion was starting to affect. Once he cleaned up, he then quietly went up to her door and listened in through the keyhole. He could hear her moaning hard. He was sure she was masturbating furiously but not successfully getting off. He knew she needed a dick badly. He didn't even need to add that effect to the potion as it would be natural.
