Kevin remained there, sitting silently, waiting for his mother to return. Rebecca followed Sam to see him off and reappeared after locking the front d...or from inside. Her heart was suddenly beating very fast, and she could feel the wild throbbing in her cunt.Rebecca pulled a chair and sat beside Kevin."Did you sleep well?" No... mom." That all he could answer.Kevin was right. Last night, was the most tumultuous night of his life. He could sleep only after he diddled his shaft for one more. “You going to be home for dinner?”“Yes mother”“So, what are you two going to do today?”“Not sure.

Kristen collapsed, crying, as she held Marie. The mother and daughter lay on the bed, covered in dog cum, as Buddy licked up the remnants.Kristen and Marie, both exhausted, fell asleep. Marie woke.
