No daughter of mine is going to college without first learning some serious oral skills. But I need someone to demonstrate on. As luck would have it, her brother is in the house...
“Cheryl! Mark! Both of you get in here this instant.”
It was time for my daughter to learn. I knew she was not very experienced with men, and with her now eighteen years old and about to go into the big wide world, it was time for me to show her a few things. No daughter of mine was going off to college without knowing how to suck some serious dick.
“Mark, get you cock out right now.”
“What?”
“You heard, your sister is going off to college soon and I need to show her how to give a blow job. You have a dick don’t you? A brother should always be willing to do his part to help out his sister.”
“Mom!” Cheryl gasped. “This…you’re our mother…that’s…that’s incest…you can’t…you can’t suck Mark’s cock…he’s your son-and I’m your daughter!”
“You’re absolutely right Cheryl. You are my daughter, and as your mother I consider it my duty to show you how to swallow some man-meat.
Mark-am I going to have to ask you twice?”
Reluctantly, Mark pulled down his jeans and underwear, to reveal a flaccid, but impressively thick cock dangling between his legs. A truly beautiful cock, like father like son.
