Yes, my my gf's mom. We'd been up on my gf's bed shirts stripped off and dry humping, and she decided it was time to get my fat cock inside her. So she unbuttoned my jeans and was pulling my cock up and out of my briefs when her mom walked in the door.

Now, her parents were always pretty cool, and her mom did NOT freak out. She looked at us...she looked at my girlfriend's hand gripped right under the head of my erect cock, sticking out of my open jeans, and she said, "I hope you're going to use a condom."

Yes, Mom we are...er, were!
