Slip your dad a couple Viagra

You don't think you need to turn your dad into your sex ****. You just want him to join in the action, so instead you slip him a few pills of his prescription Viagra. You take one yourself for good measure - this will be a long night.

Not unexpectedly your parents barely make it through dinner before they run back to their bedroom and start fucking. You give them a couple minutes to get all your clothes off before you send Emma in. Your mom is too horny to protest as Emma quickly sheds her clothes and offers herself to your dad. And if his wife won't protest, then why the hell would he? Emma gets down on her knees and takes him in her mouth. She has one hand up on your mom's pussy, rubbing it, keeping your mom pleased.

But then Emma jumps on the bed and opens herself wide. She beckons your father to come to her. He sees his wife is touching herself, so he just goes with it. Then he starts fucking your girlfriend like there's no tomorrow.

You take this opportunity to step in, buck naked, with your cock already rock hard from watching in the doorway and you move in between your mom's legs. She looks are you surprised, but so horny you can tell she'd do anything. You slide your cock easily into your mother's pussy. You slide in and out and your mom looks more and more distressed and she struggles to accept what's happening to her. "What am I doing?" she moans, but you slap her hard across the cheek to get her to shut up.

"Just take it!" you tell your mom, and this is what she needed to hear. You silenced the voice in her head that told her this was wrong. She can now just go with it - she can let you have your way with her, to use her, she can enjoys this without the guilt. Your mom grabs your ass, pulling you towards her as you thrust. If you're gonna do this, she thinks, she might as well give you a good time.
