Haruka Motoyama is a beautiful mother with two teenage sons. She doesn't want her cute sons to have the wrong knowledge about sex, so she decides to use her own pussy as a teaching material to teach them about sex! She sees her sons' penises, erect as if they're about to burst, for the first time. She gently gives them a handjob while explaining how sperm is produced, and then inserts them in the cowgirl position to teach them the wonders of sex. In the end, she even cums inside them raw to teach them how to make babies... Maybe this will lead to more siblings? Recorded in digital mosaic.
