"Hey...teach me about sex too, auntie" → "I've already cum, so stop!" A mother teases and seduces her son's friend, who has just learned about sex. However, when the monkey-like boy thrusts into her with his wild and outrageous pistons, her adult pussy, which has been completely trapped by preconceived notions until now, cums over and over again, contrary to her expectations! The unconventional and messy self-taught sex that ignores theory brings unprecedented pleasure and attacks the mother's dry and frustrated body!
