Instead of explaining the biological term, Kirsten gave a pussy licking

A slender lustful blonde lady invited a student to her home under the pretext of helping to prepare for an exam in biology. Arriving at the place, the naive guy began to ask questions, but instead of an answer, a lustful devil spread his legs and bowed the guest to lick the pussy. Then the excited couple took up a dizzying hard sex, during which she spun on a member as a wound and made a good blowjob.
