Mommy teaches you about Sex Ed

This is a mother/son video.
I am helping my son with his homework, which turns out to be sex-ed. I start talking about the female body and eventually think the best way would be a "hands on" approach. I start getting naked and showing him my body. Show him my breasts and tell him that he used to suck on them as a littleboy. Then show him my pussy and tell him it's where he was born from. I can tell this turns him on and I ask him to get naked since I haven't seen him naked in a long time...
Mmmm how much he's grown since the last time I saw him. I start giving him a blowjob and finish him off.
He cums inside my mouth..
I hope I helped you out son.
