Late at night, a smooth-haired girl secretly visits, making a promise to let her pure body be used however desired. She agrees to allow unlimited penetration and to drink every drop of semen.

Then, straddling from above, she reveals her loosened underwear and continues serving the man. A naive country girl offers her body in an overnight lesson. The experience draws her deeper into desire.
