Able to see how he affect’s others on his arm

He blinked as what looked like a status menu in a role-playing game appeared next to his sister. The menu had her name at the top and a list of things affecting her.

He slowly read the list. It said affected by charming appearance, intoxicating pheromones, and addictive flavor. Not sure he wanted to mess with anything to do with his appearance he wrote able to turn off intoxicating pheromones and addictive flavor on his arm. He felt something click inside his head and he suddenly knew how to stop his two abilities. Turning them off he watched as they slowly winked out on his sister’s display. He watched as her face started to turn red.

Lisa had been enjoying the way he tasted in her mouth when suddenly the flavor had faded, and his dick started to taste like almost every other dick she had sucked. Looking up at him her mind screamed at her that he was her brother and she should not be doing this. She felt herself blush at what a slut she was being. She told herself he was better looking than any guy she had seen before and decided she still wanted to fuck him even if that was wrong.

Matt had seen the hesitation in her eyes before she went back to sucking him. He felt his balls start to tighten and said. “I’m going to cum.” His sister pulled him out of her mouth and started to jack him off. He groaned as he blew his load all over her face. After he finished, he noticed a new item appear on her menu. It said affected by mind altering sperm and he cussed. Writing on his arm he added it to the things he could turn off.

When her brother’s load had splashed across her face, she became very horny as a new idea popped into her head. She should become her brother’s cum dump and let him fuck her every minute of every day. She started to take off her clothes knowing she would never need them again.

Seeing his sister start to strip he.
