Go to bathroom
From Create Your Own Story
You need relief but decide its too risky to do it at the table so you go to the bathroom. As you sit there jerking off you see an underwear catalog and use it for extra stimulation. In a few minutes you are ready to cum. After you clean up, you find your mother in the living room watching tv. Shes glad to see you and gives you a hug. You join her watching tv.
Later that night all of your family has dinner together.
