"Don't worry.  We'll teach your sister what happens to bad girls who don't listen.  You listen, so we'll be more gentle with you." Jar chuckled as the willing lass maneuvered herself over his fat prick.  Jar watched in sick facination as his cockhead mashed against Marianne's tiny vaginal enterance.  It really didn't look like it was going to happen, but he was determined, "Grit your teeth little girl...you can take it...here we go..." he said as he placed his hands on her hips, almost completely encircling them.  Slowly he began to apply pressure to her downward, until finally the obese head of his cock sunk into her cunny shute.<br/><br/>As for Betty, her Mom would probably think that she was a messy cumslut, since that was what she was about to become.  Mack grunted and pulled out of her mouth, only to spray her face down with his sticky ball milk.  Betty would most likely be gurgling cum bubbles for a while, after the huge load that was sprayed onto her face.  Mack kept his grip on her nipples, just to make sure she couldn't go anywhere while his cock continued to fire rope after rope of ejaculation across her face and mouth.
