Son masturbates watching his mother masturbating

Mother takes a huge dildo that had recently purchased, she thought she was home alone so I started masturbating with huge dildo and moaning with pleasure. The son who had not been to school listen to those moans and enters the room and finds his mother masturbating, then also began to see her masturbating. The mother, realizing his son invites him as a mother is very excited had wild sex with her son that morning.
